This thread is a continuation of some of the discussion that was from this thread: http://forum.xda-developers.com/showthread.php?t=2568427
While not at all high end tablets, it's always fun to see what can be squeezed out of them! As stated in the title, this thread will be regarding the following devices: Nobis NB07, Iview 774TPC, and DA-741QHD (which all appear to be the same hardware) rooting and ROMs. That should be pretty simple for now since, we currently have no ROMs and no proven root method. Some have reported success using the Kingoapp. If anyone is able to obtain root, we would like to ask that you make a copy of the firmware and upload it for those of us having trouble doing so. After doing so, we can modify it and hopefully get more our of the software.
You may also post information regarding tweaking the ROMs for these devices and other ways to make them more useful!

Warning: The following may have unforseen effects including breaking your tablet to the point of being unrepairable.
Option #1, Use KingoApp Some users have reported that this did not work for them, at least one user reported that it did.
Instructions per RawX:
For the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers. That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times. I've done this were for clients of mine but its pretty straight forward.

The working drivers for me were: VID_1f3a_PID_efe8
Please consider trying this first and give us some feedback. A word of warning though, there has been some discussion on XDA in the past that this may be malware though I'm not sure this was ever confirmed.
Option #2, Flash firmware for an alternate device that can be rooted easily. Warning!!! Currently, there is no way to get back to stock (until someone who gets root with another method makes a copy of the firmware)
Go to this website: http://www.iviewus.com/firmware788TPC/ and download the firmware. Yes, it is for another tablet. However, the tablet appears to have the same specs as ours. Once downloaded. Install the included PhoenixSuit software. Once it is running, click the button at the bottom right to update the software to the newest version (this may not be required). Then, plug in your tablet using the usb port and install the drivers. I used google and found them all within minutes. Once the software recognizes your tablet go to the firmware tab where you have extracted the .img file and select the file. Next, click upgrade to upgrade your tablet (it has instructions to help your tablet be recognized if you are having difficulty). Once the new firmware has been flashed, then download the file RootFromOTA.zip that can be found on various places such as XDA. Move the file onto an external SD card. Then, go to settings -> backup & reset -> Recovery Mode. Your tablet will restart. Once it does, select the bottom option to install from SD card. Install the RootFromOTA.zip and then reboot. Once rebooted, install the supersu app or another root application of your choice.

Congrats... You're rooted.

Mods
Currently, I've managed to get great battery life out of my tablet by installing kernel tuner and changing the settings as such:
Governor: Ondemand (default is fantasys)
Max: 1200 MHz (Default is 1200 MHz)
Min: 240 MHz (Default is 120 MHz, but I had trouble with usability at this setting and Ondemand)
I also recommend setting wifi to turn off when the screen is off and turn off autosync.
This seemed to give me a very useable system but with greatly improved battery life. Doing the above and a few other tweaks here and there have made my battery life so that it drains by about 1% overnight when not in use. I also seem to get better battery life while using the tablet. I haven't had any trouble playing games either.

I am assuming the camera is not working using this method or did you figure it out?
And also, do you have a link to the drivers you used off hand or what did you search for to find them?

Nope, still haven't gotten the camera working. We are missing some config files still. Do you need the camera drivers or the tablet drivers?
The camera drivers are : sp2518 and sp0838, though I also see a module being loaded called cam_detect
I don't recall where I got the adb usb drivers for the tablet, but it would probably be a good thing to mention in this thread so if you have them, let me know and I can add it to one of the top posts. If you're having trouble finding them, I'll remove my drivers and go back through the process to find them again.

Looking for the tablet drivers. I am about ready to tap out on this thing for a while. lol Its driving me crazy.

OK. The drivers I used were probably: VID_1f3a_PID_efe8 (or something similar)
You can either google that or try downloading the firmware for TP718AQ here: http://www.agptek.com/forum/viewtopic.php?f=22&t=948
Remove all prior drivers for the tablet. Plug it in and tell Windows to use the drivers from the extracted file you download (Will extract to TP718AQ_Update_Firmware\USB Driver).
Sometimes I have to do a little dance with restarting the device and my computer to get it to recognize it.
As a last resort you could try this: http://www.xda-developers.com/andro...r-solves-your-adb-driver-problems-on-windows/
Let me know if you have any problems.
Good Luck!

Ok, I officially give up trying to root this thing. Stupid windows will not install the drivers in both the links you provided and I cant get windows to even try to install anything after removing them then I got the android ADB drivers to install but still zero luck. All rooting apps fail. Hopefully someone will post the image of their rooted NB07. A few claim to have rooted it just fine but I cant win with this thing.
All I want is to be able to run link2sd and a few other apps that require root. This is officially the longest I have owned an un-rooted android device. lol

I'm the one that got the root working using kingo, so for the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers ( I would post a link but I don't have 10 posts yet on XDA)
That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times I've done this were for clients of mine but its pretty straight forward.

Well, I have decided that for now this tablet of mine is un-rootable. I must have tried with 5 or 6 different drivers about 20 times with each with Kingo. I even tried that other program that is all in Chinese that loads some BS app on to your phone with no luck. So, for now, I am going to give up but if anyone has any other ideas or wants me to try something or they have for sure figured out how to root it, let me know as I am happy to help the best I can.
Edit: Oh yeah, Dont know how much this will help anyone but here is some more specific specs on the Nobis NB07 tablet I pulled off it with Hardware Info 3.0.0. Feel free to put the link in the first or second post if you want. Maybe it will help a little bit more.

Thanks to the work of someone on another forum, I have now got TWRP working on our device and am hoping we will soon have a CM working on it as well. Check back in the near future for further details. Maybe if you can't have a rooted stock, we can get a fully functional CM.

I am assuming you need to have root to flash the TWRP recovery correct. This is good news. Would love to have more info on it. Are you working with people on this site or another site? I would love to follow along.

On another site for now. Just PM's at the moment so not much to follow yet. But, all you'll need is the Phoenixsuit to install it, so you won't have to root your tab first. You'll have root on the new ROM. You'll have to have drivers fully working though. Once fully working I'll link to the site so people can get the files and hopefully we can get this guy some donations for his work.

Awesome! I would go right to CM on this and skip the whole rooting the stock firmware. Would be nice to be able to root the stock firmware though then things would be so much easier. Think the camera will be working on the CM build? If not no big deal but would be nice to have them working.
Keep me (us) posted on the progress.

Not sure about the camera yet. I have CM booting but no touch yet, so this will be the first task. I'll keep everyone posted.

Any word on getting things to work yet?

Currently, we have CM working with no touch screen/camera. I'm not sure what else all isn't working because I'm waiting on my OTG cable to come in for further testing to see what all is going to be required to get the touchscreen going. Right now, it appears we my be looking at compiling our own drivers which could take some time to do. I think we'll get it eventually, but it may take some time. If you don't need touchscreen or camera, it could be working right now.

Sorry for no updates for a while. My work has been delayed on this since I have a son who is sick and in the pediatric ICU. I'll get back to work when things calm down for me.

No worries man. Family first.

Just a question, Hippie...
On the original ROM, can you see your device in ADB? If you can, and type "adb shell" do you get root? If you have adb access but not root, can you try typing sh and see what happens?
Also, could you try loading the rootfromOTA.zip and see if you can get a printout of the error log if possible?
Also, I tried installing this from the recovery on a similar ROM and it acted like it failed. I went back into the ROM and used adb and was able to get root using vroot or kingo...I don't remember which. This may be worth a shot.
Interestingly, I have been looking for alternative ways to root and found this (but we need to find a way to get to the bootloader):http://whiteboard.ping.se/Android/Rooting
I think that the method to get to bootloader is to turn off the tablet, then hold down the back button while tapping the power button 5 times. But, I also googled and found a method for getting to fastboot from adb in android without root as well which may work.

Viewpad 7 - how to root?

How to root Viewpad 7?
Anybody suceeded?
Ok,
Use SuperOneClick, just make sure to click 'run as admin' if win7. That was were I screwed up.
In case you have issues here is a step by step:
a) Download the latest version of Super One Click (currently 1.6.5).
b) Place your Android device into debugging mode, and connect to computer.
c) Right-click the Super One Click executable and select 'Run As Administrator'.
d) At program launch select 'rageagainstthecage' exploit method, then select 'Root'.
e) If there is no activity for more than 30 seconds and the terminal display is stuck at 'Running rageagainstthecage....' remove the USB plug momentarily and plug back in.
f) You should get the message “***IF IT KEEPS LOOPING, TRY DISABLING USB DEBUGGING NOW***” followed by an ADB reset, waiting for device, and finally a successful rooting message. (Apparently the looping issue is a known bug).
g) Once this process is complete your prompted to test the root condition. Follow the steps to verify.
Yes, I rooted it that way. Thank you very much!
How about unroot with Super One Click, does it work too?

I don't know of any way TV out would be possible since there is no mini-HDMI port on the device. One of the main things that should be fixed is HD video playback. It really seems like Viewsonic rushed they're tablets to the market. Aside from that and lack of Flash I think it's a great tablet...especially for a developer. Having the 3G radio and GPS is really nice, as well as the screen compatibility mode.

It uses a Qualcomm MSM7227 ARM11v6 processor with Adreno 200 graphics, clocked at 600MHz. It's been benchmarked in direct comparison to it's 1GHz Snapdragon cousins, so don't let the clock speed fool you (performance would be comparable to the original Motorola Droid). It's certainly capable of running Flash, but Adobe has been less than forthcoming about releasing a version which will support this architecture.
There are many other devices using this chip that have been released just a couple months ago, so it is still very much in wide use. I don't think anyone has ever found a workaround (aside from using Flash Lite). So until Adobe comes around, we'll be stuck using Skyfire.

I just got my Vpad7 yesterday, and i'm already annoyed at the default 2.2. Even as rooted, my milestone with 2.3.3. still outshines it.
I cant even find an update.zip it'll accept. So when you got something worth testing, or a kernel worth booting, please allow me to test it

Because Adobe decided not to support the ARM11v6 processor architecture, even though they had a working build for it. You can use Skyfire browser to watch flash videos in the meantime.
BTW, guys, where to get and how to install custom recovery on Viewpad7 ?
I can't install custom ROM, reason of stock recovery wan't install unsigned update.zip ;(
Hallo guys..
I tried on my viewpad7, superoneclick 1.7 on linux ubuntu.. but no success.. any hint for me?
always stop at
chmod..
I read to do a adb reset, but I am a bit ..
For the recovery rom I saw in modaco that there is a clockwork recovery rom ad hoc.. but I need root to install it.
ahh, before root it, I wish to have a backup, anybody know a way to backed up the original rom ?
thank you!!!
Per request I've created a separate thread documenting the installation of alternative recovery partitions and installing custom firmwares. You can find it here:
http://forum.xda-developers.com/showthread.php?t=1015005
Hello,
no it sounds that in linux the SuperOneclick doesn't work with this viewpad7..
I read some groups in germany and only windows 7 ... umm
But really there is no way to backup the rom before root?
I am in with adb .. but read not permitted..

[DEV & CWM Recovery for Pantech Crossover]

Forgive me if I'm posting in the wrong section. Forgive me if I'm not allowed to post here yet. Just forgive me in general. I don't want to be banned or anything like that. I'm Extremely interested in android development.
I made a working port of ClockworkMod Recovery v5.0.2.8 for the Pantech Crossover. I wanted to do this before I started tinkering around with porting cm7.2. So that I would have a way to backup, restore, and flash new roms, etc... Or else when I make a noob mistake like yesterday and have a non booting phone resulting in having to flash my old boot.img with fastboot...anyways..
DANGER: DRAGONS AHEAD
FLASH AT YOUR OWN RISK
YOU HAVE BEEN WARNED
The method I used to flash the recovery was:
1)adb push recovery.img /sdcard/recovery.img
2)flash_image recovery /sdcard/recovery.img
3)repeat step 2 (for some reason it gave me a read error out of memory the first time)
Here's the link to the custom recovery:
http :// dl. dropbox .com /u/20070520/ recovery.img
I know I'm not supposed to post links yet. Remove spaces
I just hope that there are others with the Pantech Crossover that are interested in this and the possible future development of custom roms.
Also if anyone knows if there is a good way to get ahold of koush let me know, so I can give him what he needs to hopefully add this to Rom Manager. I couldn't message him on github because he doesn't have an email set up with it
And while I'm at it. Here's the method for rooting your crossover. I'm not going to provide the files since they can easily be found with a google search.
1: Find a copy of gingerbreak.apk and copy it to your sd card
2: Enable usb debugging and allow installation of non market apps
3: Install gingerbreak
4: Root device with Gingerbreak
5: You can uninstall Gingerbreak when its completed.

Thanks so much for this! I have a friend with a crossover and is always looking for my help with making it work better. I realize this is a newer thread, I was wondering how things were coming along with CM? Anything I can do to help perhaps?
crap i need a rom to fix my crossover the buttons are no longer mapped after a hard reset. please help.
Slow
Well, it's been slow goings so far. I downloaded the open source files for the p8000 and it looks like they just built the original rom from a generic build. I've been trying to get a more customized build setup but I need to do some more reading so far. One of the problems is that instead of an akmd(2) binary for orientation and compass it uses three separate modules. Plus the hci_attach is a bit different as well and so is the bluetooth. So that significantly hampers the ease of even a basic port.
As far as the gentleman with the question about a rom to fix your device. The best I can do right now is to upload a clockwork mod backup after I do a factory reset. I don't get much time to work on this between my wife and daughter.
Also, do you have adb access to your device? Surely it wouldn't be too difficult to adb push the correct keymapping files back to your phone.
You say a hard reset messed up your mappings? What problems were you experiencing prior to the reset?
Crossover
Hello,
I just wanted to let you know that there are people watching your thread. I am very interested in this as my parents have Crossovers and have recently rooted and unlocked them (well, I did) and set them up to work on Net10.
The only issue I've noted is that there are some failures, like the Market refusing to install apps no matter what is done. I'm going to install your ClockworkMod in hopes that later it might be useful.
I realize there isn't a large development scene for the P8k yet, and maybe there won't be but it's always a great hope that those with the capabilities might take pity. I was almost thinking that it might be my foray into actually looking deeper at the code than the small bit I've done.
Kind Regards,
Kaylus
Yup

I haven't had any problems with the market refusing to install apps but I do sometimes run across the no connection error with the market when on wifi. Although I did notice this before I rooted my crossover. Sometimes disabling and re-enabling the wifi helps. I really do think it is a bug somewhere in the original rom.
As far as the custom recovery image. Everything seems to be working pretty good. I use it mainly for restoring previous backups. I would say I've restored my backup at least a dozen times. Occasionally it states there was an error restoring .android secure but I have yet to track that down. I need to double check the recovery.fstab to make sure I have everything set right for the mount points.

I'm actually completely stuck at this point. I'm rooted, unlocked, different carrier, APN set correctly. I can access data and voice -- but it just hangs at "Downloading..." on the market. If I factory reset it works initially but after reboot it fails. I'm not quite sure why this occurs and if it is just this phone or a side-effect of using it on a different carrier.
Strangely Wi-fi doesn't resolve it.

I'll give your recovery a run and let you know, if you manage CM7 let me know I know it's a big undertaking. Thanks for the response.
Market Error
As far as the Android Market hanging. I see a few references to it being cause by the .android_secure folder becoming corrupted on the sd card.
One temporary fix suggest moving all the installed apk's back to the phone memory and deleting the .android_secure folder. Then rebooting and moving those apps back to the sd card.
That seems like some wasted time if it doesn't happen to work. I would just turn the phone off, remove the sdcard, and restart (granted any apps that were moved to the sdcard wont work until it is reinserted.) Then I would try to download and install an app. If that works then shutdown, insert sd, and reboot.
I'm really curious if the problems with .android_secure that you and i are having aren't just more bugs in the original rom.
Just as a poster above me said, I am watching this thread and really appreciate everything you are doing. Thanks again.
Well I appreciate the support. I just hope to be able to offer a rom sometime soon. Unfortunately I won't have anymore free time till Tuesday

Ahhhhh check out the pantech support page for the crossover. They finally have the Gingerbread update.

Which is great because I soft bricked my phone (don't ask) and this was going to be the only way to fix it.

Mildly related, but have you figured out how to root the gingerbread ROM? I've tried ginger break to no avail.

anyone have a stock image of the 2.2 for android my phone came preupgraded to 2.3.6 and i would like to have it rooted over being on gingerbread since a root method hasnt been found yet for the new firmware
Bricked?
I tried to use the pantech provided gingerbread update this morning. It got about an eighth of the way through and failed. It instructed me to reboot while holding volume up and home and power. That put it in software updating mode. I tried the upgrade 3 more times, it failed at the same point each time. Now my phone is stuck in S/W Updating mode and I can't seem to get it out. I've tried pressing volume up and down for 10 seconds, and pressing volume down and home while powering on, nothing seems to make a difference. Any thoughts about how to at least get me back to froyo?

Lenovo IdeaTab A2107A-F

I am starting this thread to hopefully encourage discussion on the Lenovo A2107A-F tablet variant.
I am aware there is an existing thread on the A2107 here:
http://forum.xda-developers.com/showthread.php?t=1982334
but that thread is concentrating on the A-H (dual sim + wifi) variant which is somewhat different from the A-F (wifi only).
So far I have not found any custom rom development, which is disappointing as the stock rom leaves a lot to be desired IMHO. While the current OTA update is fine for web surfing, reading emails etc, HD video playback (particularly YouTube HD) is very poor. Also the recent OTA update forces an optimization of apps on bootup which leads to long boot times
You can root and install CWM by following steps 1-5 from the 1st post here:
http://forum.xda-developers.com/showthread.php?t=2044496
Note that "-Update 3-" mentioned in the post does not appear to work for the A-F model!
So, has anybody any leads on possible development on this tab?
Any tips on improving performance?
My first tip:
If after installing CWM you cannot get to the CWM recovery screen after powering down the device, look for for the file "/system/reboot-from-recovery.p". If it's there, either delete it or move it to some other place. This file restores the default recovery on a system reboot.
I got bitten by this a couple of times
Thanks for starting a separate thread for the A2107A-F. I'm new to Android devices and just got this one two weeks ago. I'd like to get rid of several of the apps that I have no use for and from what I understand that means I have to root it. I got lost in the details of the other thread, but I tried reading all of it. I'm on Vista and somewhere along the line I installed one of the suggested ADB drivers via PDAnet. Device Manager is showing Android Phone and under that Android ADB Interface. I wasn't sure if that matched closely enough with the step-by-step threads since I don't really think of the device as a phone, so I've been holding off on going further. I've tried using a few other drivers that were suggested in the large thread and some other threads, but Vista always tells me the current driver is the most up-to-date one.
Do you know if it's okay for it to say Android Phone rather than something else?
Thanks. I've got some other questions about the specifics of some of the other steps, but this is probably enough to get started.
My apologies in advance if my posts are too long and my questions are too basic for these forums. Feel free to point me somewhere else based on what I'm asking for. I'd honestly appreciate any leads towards my goal of getting rid of the bloat on this device and making it more responsive. (Wow! The portrait to landscape lag is really bugging me now after reading around here).
Anyway, my primary purpose is to remove the seemingly unneeded programs, services and widgets that come with the tablet. Maybe I'm just ignorant about these things, but at this time things like messaging (IMO), mapping, and some of the other default features are of no use to me. They seem to be eating up a lot of resources. I can kill some of the services I think they are associated with, but they keep popping back up.
I did watch the "noob" video (color me a tiny ant to be squashed) and did try to search for an answer to get me even started. I've read the huge main A2107A thread (80+ pages) and tried three of the suggested ADB drivers with my Vista 32 setup for my A2107A-F. The only one that even seemed to connect was ADPnet and it showed the tablet as a Android Phone. Maybe I'm just too paranoid, but after the multiple "brick" posts I'd like to make sure I'm on the right path before trying to "root" the device which appears to be the first step in removing all the extra stuff Lenovo added.
Not that it matters, but I've had the tablet for almost two weeks now and my favorite things are Slacker Radio, Scrabble, Roll It and Zen pinball. I do play Words with Friends with my wife, but I don't like it since some of the words they allow are not valid in Scrabble (which I used to play as an expert competitively face-to-face).
If you are so inclined, feel free to PM me for a Scrabble game. I promise I will not use anything other than my brain and the built in dictionary to make my plays. (I'm a bit rusty since I gave up competitive Scrabble in 2006).
So, long story short... Thanks in advance for any and all advice you can give on slimming down the Lenovo A2107A-F. And if you want an honest Scrabble challenge feel free to PM me.
As far as checking if your drivers are installed properly I would open a dos (command) prompt in window and from within the window change to the directory where you have the 4.03root files. From the command prompt type 'abd.exe shell' and you should see something like "[email protected]:/ $". If you don't see this then you will not be able to root! You need to make that USB debugging is turned on on your device you have an entry in the device manager for ADB Interface (expand on the device which you have showing up).
I am no expert, and I struggled with this on my first go also
Once rooted you can then install Titanium Backup from the play store and use it to get rid of the bloatware! Proceed with caution however as it is possible to remove critical system apps!

Thanks! That's the type of test suggestion I was looking for to make sure I was on the right path with the driver.
So has anyone tried creating a rom for this tab yet? I've been doing some research into porting another rom to work on the A2107A-F, but want to make sure there isn't one already.
I just received a notification of a new firmware update for the A2107A-F. This would be the second available update.
Has anyone else gotten this and taken the plunge yet? I'm curious if this is possibly Jellybean, as some of the larger screen IdeaTab models run this.

I lost root after applying the first update a while back. That's typical when updating. Afterward, I was able to re-root mine again using the same procedure as before. All was well. So, don't panic...yet.
Can you report on what other changes the update made? Is it Jellybean? Or maybe ICS 4.04?

Well, I just re-rooted my tablet and everything was successful! There is absolutely no difference AT ALL with that so called "update".

Although I have my A2107A rooted and tweaked to my satisfaction, there are a few lingering issues that I'd hoped an update would correct:
1) The neutered Bluetooth stack. The tablet is supposed to work with Bluetooth keyboards, mice, etc. It doesn't. Although I've gotten it to talk to an external GPS module, other Bluetooth data connections simply will not work. Oh, and Bluetooth audio? Forget about it!
2) Some settings that are present in stock ICS builds are just omitted in this one. As an example, the ability to specify a default TTS voice. It's present under settings in my wife's tablet and every other ICS build I've ever encountered. Not this one!

I was rooted too, lost root access (only with some apps!) after the 130221 update Feb 28. I'll try the same root procedure as before to see if I can get it back. Glad to see a thread on the popular US version A2107A-F. Maybe someone will port Jelly Bean to this tablet! Doesn't appear Lenovo wants to do it...

I cannot get this 'update' to install after downloading. The tablet reboots to CWM during the install (I am rooted with CWM installed) and when I attempt to manually select the update.zip from /sdcard/googleota/ I get on error (status 7). In desperation I re-loaded the stock rom that I found on another thread and when the tablet attempts to update I get a "assert failed apply_patch_check( /system/app/applicationsprovider.apk)" error Anybody any ideas?

I'm in exactly the same boat as you. I'm getting the same exact error. except that I do not have CWM installed (I am rooted though). Perhaps there's a problem with the update.zip?
Something odd that I noticed however: After the tablet reboots into recovery mode, the update fails, and I go to browse for the update.zip, the sdcard/googleota directory is missing (along with everything that follows it alphabetically). They reappear upon normal boot. I've tried copying it to a directory closer to the beginning of the alphabet and it does show up while in recovery mode. But it still will not install.
Maybe I somehow do not have the available space to perform the update? Is that possible? I show plenty of available space on both sdcards. Could we somehow be below a certain ROM space threshold necessary for an update?
I think in my case because I loaded a 'stock' rom I got from another thread, this rom is failing a verification test the update is doing before install. I do not know how to get around this! I'm continuing my search, but I am not so confident this will be resolved easily...

Well, I am running a stock rom. I am unwilling to "mess with success" until there's a 100% reproducible way of recovering if it fails. And, so far, everything I've read in the other A2107A thread has been hit or miss for the A2107A-F people.
Anyway, If the update is performing a verification test, then it my "virgin stock ROM" should certainly pass it. The only thing that I did is to root it. Hmmm...could the update be testing for that and refusing to install if it detects a rooted device? I would tend to doubt that, since the previous ota update went just fine. I lost root in the process but easily reapplied it afterward.
Thoughts?
Interestingly, I flashed the A2107A-F_S483_121115 rom (again, found in another thread) as I was having verification problems with the OTA update just released from lenovo which was available from the A2107A-F_S484_121211 flashed rom. While the S483_121115 rom appears to be older, I no longer get the option to update via OTA as the tablet is telling me that my s/w is up to date! Go figure.
It's really too bad this device hasn't taken off. If I actually knew how to dev then I would start developng ROMs for it. I'm enjoying it now that I have root and got rid of bloat.
Hey guys. Just wanted to say if someone can send me a stock rom and be willing to test, I'll try to do up a good rom for the -f models. I'd use mine for the stock rom, but I've edited a lot of the system, so no go there. If you have the stock rom or want to be a tester, let me know.

[Q] Need help desesperately. Here's a challengue!

Good morning everyone.
First of all I want to apologize for my english, that I'm afraid it's very poor.
My question goes next: I bought an used Samsung Galaxy tab 2 7'' p3100 3G and it has a very big problem. It can't be connected to any pc, windows or mac. It's not a drivers' problem, so when the device is connected, the pc does nothing. Not even a display in the device manager, or a noise. However, it usually charges. I say usually because sometimes the icon battery shows a red ray, but it charges spending more time. That's all. It has been proved with three different original cables in several computers running different SO.
I don't know if it's a connector problem or it's a Rom one. It has an operator locked SO with Android 4.0.4 that not even shows the OTA update option in the menu. And I cannot select the way I want to be connected by usb in the "Storage" options.
The fact is I cannot update the device and I cannot root it in order to install a better rom or an original stock one.
I've googled all I can do to find a way for rooting the device, but all the roads drive me to the same point: Odin. The software I cannot use because my device can't be connected to any Pc.
I know this forum is my last chance. There are some ways like z4root or framaroot that work in another devices (Galaxy S for example, I think), but they have not been ported to my device. I think my chances are to make it by an apk o perhaps flashing a signed file from the original recovery.
I just need to install a simple clockword mod or having the device temporary rooted to install and run the Odin's apk that allows me to install a pre-rooted rom, an open recovery... Just a simple step for one man, But the Colorado's Canyon for me in my situation.
If someone of you know any solution or want to help me, I'll be truly grateful. And I didn't even mind to pay him for his help.
Thank you very much in advance.

Have you manually installed the drivers? If not, download the samsung drivers, install and try again. Read through the link below to find the drivers.

Unfortunately yes. I've tried with several versions of Kies, by installing manually the drivers and it doesn't work. The fact is I connect the device and the pc does nothing. Not even the device manager shows a new device or is alterated in some way. It's like one data pin in the connector was damaged or the rom was corrupted and it doesn't let the device be recognized.
I think my only chance is to make everything inside the device. By sd in the boot manager or with an apk. If not, I'm condemned to an obsolete device that could not even be updated.
Thanks for trying to help me.

your cable is faulty. Get another one on ebay cheap.
I'm afraid I've tried with three different cables, as I said (one of them original from Samsung and new), two Windows Pc's, one mac and about fifteen different drivers.
Believe me: I've rooted with no problem more than twenty different devices (and jailbreaked another ones ) and this is the first time I cannot make it.
Think it's a hardware problem or a corrupted rom one. In both cases I have to root it by an apk or a flash from the sd.
Anyway, I appreciate very much your help, boys.

I'm in a similar situation with a Galaxy Tab 2 p3113tsyxar
It is not recognized by any computer, and my next step is to try another cord manana. Until then (hopefully) I've got a nice paperweight.
You have not rooted ur tab till now......so u have not played with your firmwares! So its better to visit a samsung store. If you have warranty then they will do it in free.(And your android will also get updated!)
If I helped you, just press thanks!

Updating advice please ! Reroot failure

Hi everybody ! Ill try to keep it simple as I'm sure its covered somewhere but here goes ....
Ive been using my shield portable, rooted, for ages now no problems.
Like many Ive updated it in short ever since nothing whatsoever has worked properly , most annoyingly the screen doing backflips when you go near it and hundreds endless strange updates when rebooting.
Anyway I don't think you or I or any of us want to waste time trying to figure out why its done any of this but I just want to be able to fix it. I guess I'm going to have to start again somehow! its worth noting here that all my backup apps like Helium now don't seem to work.
After the update I of course ReRooted and it appears fine from boot loader , still says unlocked. but upon usage its clearly very confused about whether its rooted or not !
In short its useless. Advice please My kung Fu warriors
May your arrows fly straight and true
I have no idea about the various issues, but I would perform a factory reset, and clear cache and dalvik cache using at least 3 swipes per each function. The method of rooting I recommend is by flashing a zip of SuperSU from a custom recovery menu. CWM or TWRP are both available for the NSP. After flashing SuperSU, when you reboot and go into SuperSu you'll see that it's installed (locked down tighter) as a system app.
Downloads:
SuperSU (latest stable version) v2.65
CWM Recovery Menu (latest version) v6.0.4.4
TWRP (Modified recovery (based on TWRP v2.8.7.0)
Sorry. This is the best I can offer you right now. If this doesn't work I would reflash the stock images of whatever OTA you wanna be on. The images can be found @:
SHIELD Open Source Resources and Drivers. You'll need at least the platform-tools portion of the Android SDK (to use Fastboot to flash from recovery). A user friendly PC app that can basically do all this sort of stuff is Shield Ram v1.1. You might find that easier to use.
Oh and here's the latest Minimal ADB and Fastboot Drivers installer [v1.3.1]
If you need further help, let me know.
Hi ! Thanks for the good advice.
I should have mentioned, I'm using a Mac now.
From what I understand it's still possible , maybe
Even easier.....

Yeah, pretty much the rule is generally "as long as you can still see the screen, it's probably fixable". Sounds to me like your best bet, would be to download the OTA you wanna be on, and flash a new install to your Shield. It's the quickest way from A-B. I'm about 99% sure that this would solve the problem (as long as you re-root it properly). Though if you have your reasons, you can try some of the other things first. You're welcome and let me know how things go!
So where does one get the latest OTA?

I did link up the main Nvidia page that would lead to the OTA images, but here's a direct link to DL just the OTAs:
Edit: you can get there through the link I included in my previous post: SHIELD Open Source Resources and Drivers. I'm having issues with editing posts, and all sorts of odd **** with the link trying to post a more direct link. It's an Nvidia site, just scroll down to Shield Portable Recovery OS Images (something like that).
Unfortunately there are only Linux and Windows downloads available. I'm not sure what your best option would be, as you have a Mac. You could contact Nvidia support, and see what they say about it. Sorry, but I don't think I can probably help much more than this.When I contacted Nvidia support about a year ago, they were pretty helpful. Hopefully you get this sorted soon. Oh and the OTAs are flashed via a terminal/command prompt. So if you can emulate DOS on your Mac (which I don't see why not...DOSbox? maybe) then that sounds to me like the solution.
Ok , hit another brick wall. Im using a windows computer now, followed all the instructions i can find, and now the bootloader seems dysfunctional.
Ive got adb and fastboot and its recognising the device but once rebooted into bootloader which loads fine, the commands say no device found and nothing works in this mode.
If i hit recovery mode then a little dead android appears! poor little guy.
I tried shield ram but it had same problems, seems to run fine but cant find shield once its in bootloader...
Ive got the image zip of the update i want to flash but no idea if im doing it right- not sure how to use it.
Help!
