Database Info

After rooting, screen looks dead.

I received my transformer today and looked on google for how to root it.
I followed these instructions posted by UBRock on androidforums.com: (as I'm new I cannot post outside links, so I copied the instructions at the end)
After step 4a, my TF booted up like it normally would, with the EE pad screen. Then my screen went to what is shown in the attachment.
I'll turn the screen off, and it will turn on and off by itself.
I've googled and haven't found any issues with rooting this device.
Did I just kill this thing in a few hours? I followed every instruction and had no issues until this.
I bought it off amazon if that matters in case I have to return it. I really hope there's a solution, I got it for a vacation I'm leaving for on Monday.
instructions:
I used this to root my Transformer after the official 3.1 update and it works great. Fast and easy!
The only thing you have to do with ADB is to make sure you have adb installed properly on your computer. Everything is done via scripts.

Some background info. Highly recommend reading these if you don't know what either is!
Rooting Explained + Top 5 Benefits of Rooting by androidpolice.com
What is ClockWorkMod recovery and how to use it by addictivetips.com
STEP 1. Make sure you have all the correct asus drivers installed. Not sure if this is necessary but i had them all installed previously and i didn't run into a single issue.
1a. Head over to Asus Support/download page for the transfomer
1b. Select your PC's operating system from the drop down box.
1c. Download and install the USB driver, Asus Sync, and EEE Pad Pc Suite (don't think this one is needed but i installed them all when i first got my tf).
Step 2. Verify that you have adb running properly.
Since adb.exe is included in the download, you really don't need the sdk or adb from elsewhere.
2a. connect your tf via USB to your PC after installing the driver and other apps from step 1.
2b. Open Command prompt on your pc (win key+R) and open (and extract) Tf_rootkit_31 (link at bottom of post).
2c. Navigate to /tf_rootkit_31/root_app/ folder from the downloaded and extracted file, drag "adb.exe file to the open command prompt window.
(it should read something like C:\....\tf_rootkit_31\adb.exe)
2d. After the "adb.exe" press space bar and type "devices" (w/o quotes ofcourse) press enter.
If it says "List of Devices attached" and under that a 15 mixed numbers and letters (serial number) followed by device then adb is working!
If NOT, look at the stickies or search on google on getting adb to work on your OS.
STEP 3. Now the fun begins Here we will put the TF in APX mode and install the APX driver.
3a. Shut your TF off and while plugged into your PC, hold the volume UP and Power button until your PC makes that USB device plugged in sound and there is a notification about installing drivers.
3b. Open up the driver install thing in status bar and press on cancel (or whatever it is to get it to stop searching online for the driver).
3c. Open Device manager, scroll down to "Other Devices" (might be named something else in xp or vista) and you should see APX something with a small exclamation mark in a yellow triangle.
3d. Right click it, select "Update Driver Software..." -> "Browse my computer for driver software" -> "let me pick from list ..." -> click next -> "have disk" -> Browse -> navigate to the downloaded tf_rootkit_31 folder, open usbpcdriver folder and select "NvidiaUsb.inf" -> open, and all it to install, Ignore the unsigned error, let it install anyway.
STEP 4. Get to installing! Now your TF should be in APX Mode (if memory serves me right the screen should turn on.
4a. Go to the downloaded tf_rootkit_31 folder and double click on root.bat (on the TF screen it should say something along the line of "...update successful..."
4b. (OPTIONAL) if you want clockwork mod recovery, then go ahead and double click cwm.bat [Follow STEP 6 to update CWM]
4c. Restart TF, once rebooted make sure USB Debugging is enabled (Settings->Applications->Development)
4d. double click root_app.bat (this installs su and superuser.apk via adb, so command prompt will open up and do its adb thing and reboot your TF)
STEP 5. Confirm completion and CELEBRATE!
5a. Open your app drawer up after reboot and check to see if the Superuser app is there, if so install an app that requires root access (root explorer, adfree, titanium backup etc) and once you open it up, if you get a box requesting super user permission the you got it working!
5b. do a naked/underwear dance!
STEP 6. Update CWM recovery!! You will need a microSD card
6a. Go over to the CWM thread and download latest version of CWM recovery
6b. Place that downloaded .zip (DO NOT UNPACK) on your microSD card
6c. power TF off, then hold voume down + power button, when you see white writing in the top left of the screen press volume up and you should now bee in CWM recovery. Use volume up/down to move through the options and power button to select.
6d. Scroll down to "Install zip from sdcard" press power button then select "Choose zip from sdcard" and now it should list what is on your microsd, Scroll down and select the .zip you downloaded (as of this writing latest version is named recovery-3.1.0.1-solarnz-R3-240511-1908.zip)
6e. Follow instructions on screen, should be straightforward. And now your CWM is updated!

I can't post links, but it's the thread "Asus Transformer NVFlash Stock 3.1 Recovery Roms" on transformerforums.com

You guys extracting the 3 img files and putting it in the NVFlash root folder?

after sweating it for alittle while i was able to do as you guys said above.. downloaded the files placed them in the nvflash folder and recovered the system back to original state. Happy to say that im back to 3.1 now i have to work on trying to get the 3.2 pushed ota.. I do think this rom i just pushed into it is not factory original cuase now i can see the post and the 3.1 rom is rooted.. but im just glad to be back up and running with this amazing tablet..

[Q] CMW (internal storage) no ROM (on SD) on TF101 b80

hi! my apologies but i searched and read alot of post already on how to solve this.
i flashed Roach latest CMW how ever being so stupid i forgot to put a ROM on internal memory. did full wipe already and i have no ROM to flash as it reads internal memory only.
ive read alot of post regarding the concern, i want to try to push a ROM on internal drive using ADB but when i run "adb devices" nothing is found.
any suggestions or any links to posts that i might get help or tutorial. im not an expert on using ADB so keep instructions simple, im a noob i admit it but i just need help. thanks!
read through posts "[Troubleshooting/Solved] ClockworkMod recovery 5.5.0.4 from Koush" "Used roach's new CWM recovery, now can't intall rom" "

im on recovery and when i run adb devices it just blank. any walk through is much appreciated!

Do yo have USB debugging on?

I dont know because i was about to flash a new rom so i did a full wipe already

Did you ever get ADB working before all this? USB debugging usually have to be turn on by the user. In Settings>Developer options.

i havent with my tablet but with my htc desire hd i used adb. and when ever i flash a ROM on my tf i usually turn on usb debugging always. right now in on recovery roach r2. my ROM is on my external memory. also tried to do a nvflash how ever whenever i run the download.bat cmd opens then closes 3 secs maybe

i also got a new sdk from this forum " [GUIDE] Getting ADB Setup; An Idiots' proof guide on getting ADB working for Rooting!" as ave said above when i type "adb devices" its just blank and does not list any device.

I had exactly the same problem - I'm not sure about tablet version that I own, but I've flashed Wipe Lite and new Recovery. I also have HTC phone that I've been using on the same PC .
I've spent an hour trying to get my TF back on feet and I managed it.
I would recommend uninstalling all HTC and ASUS software and drivers, rebooting PC and installing just ASUS PC Suite. It worked in my case - suddenly Device ID showed up for a few seconds before ADB reported "no device" again.
So I've pushed Rogue XM Recovery to data/media:
adb push roguexm data/media
Of course use name of zip file instead "roguexm" in command above.
After that zip file showed up on sdcard and I could flash it - it doesn't support AROMA but it works quite fine otherwise.
Hope it'll work in your case. Good luck!

Hope it will help
I once were in your case, did full wipe and forgot to put a Rom in internal memory. But in my case I just rebooted the transformer and all of a supprise, my tablet reverted to the stock Rom! I dont know how this happend but may be Asus did something to keep stock Rom persistent whatever you have flashed roms or CWMs.
So i hope this also happened in your case, just give it a try. Good luck!

If he did "Full Wipe - factory reset" then he should be able to boot HC/ICS and from that copy files onto internal /sdcard.
But if he used Android Revolution Super Wipe script either Lite or Full then he has nothing to boot into, no system at all - I've done that Only thing that left was recovery without external sdcard support, so I had nothing to install...
ASUS and HTC drivers have some issues and make everything harder than it should be, that's why I recommend to uninstall all HTC and ASUS software, rebooting PC and installing ASUS PC Suite only, to have "clean" drivers on PC.
I've tried different drivers and none of them worked, until I've done that.
Ok, I'll try to write it simple, I'm not sure if I can post links so just in case I'll give thread names. If it will be too simple don't get mad - ok?
1. Uninstall ASUS and HTC software, reinstall ASUS software like mentioned above.
2. Create folder on your C: drive called CWM
3. Go to post "Eee Pad Transformer Android Development\[Recovery] Rogue XM Recovery v1.3.0 (CWM-based Recovery v5.0.2.7" thread - http://forum.xda-developers.com/showthread.php?t=1446019
and "save as..." cwm_recovery-5027_rogue_rburrow-tf101-r1.zip to C:\CWM
4. Highlight/select command below:
adb push cwm_recovery-5027_rogue_rburrow-tf101-r1.zip data/media
then right click on it and select "copy" - it will save you typing it later.
5. Boot Recovery on your Transformer and connect it to PC, let system install device drivers
6. Click START, "Run...", type: cmd
7. It should show you path to your profile folder - C:\Users\yourname>
8. Type: cd /CWM
it will change folder to C:\CWM>
9. type: adb devices
(it should give you your device ID, if it still will give "no device id" then there I can't help you - I'm sorry)
10. right click on black background and select "paste" (you'll see command that you've copied from number 4), then press enter
11. It should copy recovery onto your internal sdcard - you will be able to select it from tablet
12. type adb kill-server and disconnect tablet, install new recovery and from that one you will be able to select external or internal sdcard
Notes:
I don't know why but I was able to send only small file from CWM-adb connection, it kept disconnecting quite quickly that is why I recommend sending Rogue XM Recovery instead of whole new ROM.
Other thing - it may depend on what windows system you have - I'm on Win 7 x64 (don't remember how it worked on other versions) and I can paste onto cmd (black) window without problems from right click menu. If you won't be able to paste there or you'll get some rubbish, try to right click on top bar and select "Edit" and then "Paste".
Ok, that's all. Hope it will work.

thanks for all inputs. i did a full wipe but not as scripts. i wiped manually. i did try to reboot but stuck as eepad screen. will try to re-install asus drivers and uninstall htc ones. hopefully i get it done today. i will update later...

still no luck. device not found. im going to try to install new sdk... i hope it works. ive already removed htc sync and drivers. also re-installed asus sync and updated drivers. on device manager detects on other devices transformer but drivers are not installed.

yahoo! got it working now. i had to enable adb usb Drivers for Nvidia Tegra based Android Tablets and re-install SDK download android usb and learn What Is ADB And How To Install It With Android SDK.

How did you install CWM 6.0.1.3? Did you use ROM Manager? If so, that is your problem.
You need to get a working recovery installed.
Are you sure you could not get into APX Mode? It is a black screen and the only indication is that your computer detects new hardware.
If you cannot get into APX to use EasyFlasher or NVFlash, is your tablet recognized as an ADB device in CWM? If so you can push a new recovery using the dd command. I would recommend checking out TWRP.
To install TWRP via ADB, download the latest TWRP from here: http://techerrata.com/file/twrp2/tf101/openrecovery-twrp-2.3.2.3-tf101.blob
Save it as TWRP.blob in an easy to find place (like c:\TWRP.blob)
Connect your tablet to your PC and update the driver and use the Universal Naked Drivers
Put the adb.exe file in the c:\ folder as well (in the EasyFlasher Tools folder)
Open a command prompt (WIN+R, type CMD and click OK)
Code:
adb devices
(if connected, should show a device connected)
adb push c:\TWRP.blob /sdcard/
adb shell
cd /sdcard/
ls -a -l
(check for TWRP.blob)
dd if=/sdcard/TWRP.blob of=/dev/block/mmcblk0p4
reboot
Do not try to enter recovery until after it reboots past the Eee Pad logo (and shows the progress indicator). This is when it acutally updates the recovery.
Once you see it get past the Eee Pad screen hold VOL DOWN and POWER for about 12-15 seconds and then press VOL UP once you see the small text and it should boot to TWRP recovery.​
Here are the ADB commands to run:

When I connect to PC it makes the connection sound but doesn't show as a removable drive so I can't use Easyflash or any program like that also like I said APX mode wont work it makes the sound that it detects the tablet but then makes the remove sound right away. and this happened when I installed the Cyangenmod 9. I found someone who says he may be able to fix it for $50 using Odin but I am worried that he wont be able to and its an hour drive to take it to him... At this point I just want it back to stock ...

erm... ODIN won't work with a transformer, it's only for samsung devices.
Alright, you probably used ROM manager judging by your Recovery version.
You need to just NvFlash the device back to stock:
Download your region's Stock ROM from here: (WW if outside of US, US if inside.) Stock Rom
Download Wheelie NvFlash tool from here: Wheelie
Unzip the stock rom .zip first, into it's own folder. Then unzip the wheelie tar.bz2 into the folder you just made by unzipping the stock rom. Overwrite any files with the wheelie files.
Next find out your Sbk variant, Look at the serial number on the sticker on the bottom of your tablet.
If it says B70, or a higher number like B80 or any C, then you are Sbkv2
If the number is B60 or lower, you are Sbkv1.
Remember this for the next step.
Make sure the tablet is off totally, Then hold the Volume-UP key and Then press power, keep holding volume up. It will enter APX mode.
Plug it into your computer, the screen will stay blank.
It should be detected, if it says unknown device or similar, use the windows device manager to select the 'asus bootloader interface' or 'Unknown device' or similar, with Nvidia ASUS or APX or Bootloader, something along those lines, to update the driver, right click this and navigate to the 'usbpcdriver' folder in the folder you unzipped earlier. It will install and detect.
Then run the .bat file that says Reflash_(Your Sbk version).bat while the tab is connected in apx mode.
It will return to stock, give it time, DO NOT UNPLUG IT.
The screen may flash, and the tablet may/will reboot.
When done you will be on Stock latest from ASUS.
If you want safe root / recovery, download and run my PERI tool, link in signature.
good luck.

ok I am trying that now but I wish I had someone to walk me through everything in real time...

I had similiar problem when I tried to downgrade and go back to stock. After flashing stock from asus, I did it wrong by unzipping (stock_ics_kernel_9.2.1.24US-secure) first then flash the file under the downloaded zip files. Now I am also stuck at Eee Pad, can't get into recovery because it probably wiped out everything. Hopefully this can recover my Eee Pad!!!! I got my fingers cross. This may be my only hope for my asus pad .

Hi there,
Have you tried downgrading to .15.3 and rooting with motochopper? See my post in this thread for more information.
Good luck on getting root access.

So you want to downgrade to .15.3 from .27.5 with a locked bootloader. Okay, thats easy because thats what I did to get root after I lost it to a OTA update.
DO THIS AT YOUR OWN RISK-I TAKE NO RESPONSIBILITY IF YOU ACCIDENTLY BRICK YOUR DEVICE!!!!
Downgrade to .15.2 from .27.5 or similar.
1. Download the .15.3 firmware for your device and region from ASUS' website. MAKE SURE THE SKU IS THE SAME AS YOUR DEVICE. e.g., I have WW, so I used the WW firmware. To find out your SKU, go to about tablet and in the build no., it will tell you your SKU, eg build-stuff-here.WW.10.more-number.27.1.
2. Extract the .zip file you downloaded twice. There is a .zip inside a .zip. You should end up with a blob file and a folder. The blob file is the one we need.
3. Make sure your device is backed up via the ASUS app backup, and that all important stuff is backed up.
4. Make sure you have the correct ADB and fastboot drivers. VERY IMPORTANT.
5. If you don't have the Android SDK or access to the fastboot/adb command line, download and install this. It's what I use.
6. Restart your PC to make sure your drivers and software are installed properly.
7. Get your device into bootloader mode. You can do this by...
7ai. Whilst the device is connected to the pc, type "adb devices" (Without quotes) in adb to see if your device is connected properly. If you see your devices serial no., it's working properly. Or else, make sure you have the right files and the device is connected to your pc.
7aii. Type "adb reboot bootloader" (Without quotes) and hit enter. Your device will boot into the bootloader.
****or****
7b. Press and hold the volume down and power buttons until it goes into bootloader mode.
8. Copy and paste the blob file to the root of where your fastboot is running from. If you used minimalistic adb and fastboot. Right click the shortcut, click properties and then open file location. Copy and paste the blob file to there.
9. Make sure your tablet is the only android device plugged in.
10. Execute "fastboot devices" (Without quotes) to make sure that your device is set up properly. If you see your devices serial no., it's working properly. Or else, make sure you have the right drivers/software and the device is connected to your pc.
11. If all is well, execute this command.
Code:
fastboot -i 0x0B05 flash staging blob
DO NOT INTERRUPT YOUR DEVICE DURING THIS OR YOU WILL HAVE END UP WITH A BRICKED DEVICE!!!!
12. It will send the file to your device. When you see blue progress bar, it is now flashing the blob file.
13. Go make yourself a cup of coffee. This may take a while, and staring at it will only make you anxious. Take this advice seriously.
14. When you get back, it should of successively completed.
15. Run "fastboot reboot" (without quotes" to reboot device.
You should now be downgraded.
You may/may not have a problem with the launcher (this happened to me). But if you do, follow these steps...
1. You should be able to log in, but then as soon as you do so, launcher force closes.
You have two options.
2. Swipe down on the right side of the status bar to reveal the quick settings, and then click on settings to go to the settings app.
3. In settings the settings app, Select apps, then all apps.
4. Navigate to "launcher" then clear cache then data, then finally force close.
5. Hit hit the home button, and everything should work as normal
****or****
6. In setting, choose launcher and switch to the ICS launcher.
7. Reboot as prompted
This post will be updated with more information soon. I'm proofreading for any mistakes now...
If you want root, use mottochoper, and then install and use the XPOSED framework because it makes your stock rom feel like a custom one. Its pretty straightforward from there.
If you have any questions, just ask, and remember...
Hit the "THANKS" button, it's a good habit to get into.
FYI, I won't respond to your queries in the next 12 hours since I need to have my sleep, you know. It's nearing the darkness of the night in my side of the sorld. Thanks for your understanding. Speaking of thanks, hit the "THANKS" button if I helped you. I spent a lot of time typing this up!

To find out your SKU, go to about tablet and in the build no., it will tell you your SKU, eg build-stuff-here.WW.10.more-number.27.1.
2. Extract the .zip file you downloaded twice. There is a .zip inside a .zip. You should end up with a blob file and a folder. The blob file is the one we need.
3. Make sure your device is backed up via the ASUS app backup, and that all important stuff is backed up.
4. Make sure you have the correct ADB and fastboot drivers. VERY IMPORTANT.
5. If you don't have the Android SDK or access to the fastboot/adb command line, download and install this. It's what I use.
6. Restart your PC to make sure your drivers and software are installed properly.
7. Get your device into bootloader mode. You can do this by...
7ai. Whilst the device is connected to the pc, type "adb devices" (Without quotes) in adb to see if your device is connected properly. If you see your devices serial no., it's working properly. Or else, make sure you have the right files and the device is connected to your pc.
7aii. Type "adb reboot bootloader" (Without quotes) and hit enter. Your device will boot into the bootloader.
****or****
7b. Press and hold the volume down and power buttons until it goes into bootloader mode.
8. Copy and paste the blob file to the root of where your fastboot is running from. If you used minimalistic adb and fastboot. Right click the shortcut, click properties and then open file location. Copy and paste the blob file to there.
9. Make sure your tablet is the only android device plugged in.
10. Execute "fastboot devices" (Without quotes) to make sure that your device is set up properly. If you see your devices serial no., it's working properly. Or else, make sure you have the right drivers/software and the device is connected to your pc.
11. If all is well, execute this command.
Code:
fastboot -i 0x0B05 flash staging blob
DO NOT INTERRUPT YOUR DEVICE DURING THIS OR YOU WILL HAVE END UP WITH A BRICKED DEVICE!!!!
12. It will send the file to your device. When you see blue progress bar, it is now flashing the blob file.
13. Go make yourself a cup of coffee. This may take a while, and staring at it will only make you anxious. Take this advice seriously.
14. When you get back, it should of successively completed.
15. Run "fastboot reboot" (without quotes" to reboot device.
You should now be downgraded.
You may/may not have a problem with the launcher (this happened to me). But if you do, follow these steps...
1. You should be able to log in, but then as soon as you do so, launcher force closes.
You have two options.
2. Swipe down on the right side of the status bar to reveal the quick settings, and then click on settings to go to the settings app.
3. In settings the settings app, Select apps, then all apps.
4. Navigate to "launcher" then clear cache then data, then finally force close.
5. Hit hit the home button, and everything should work as normal
****or****
6. In setting, choose launcher and switch to the ICS launcher.
7. Reboot as prompted
This post will be updated with more information soon. I'm proofreading for any mistakes now...
If you want root, use mottochoper, and then install and use the XPOSED framework because it makes your stock rom feel like a custom one. Its pretty straightforward from there.
If you have any questions, just ask, and remember...
Hit the "THANKS" button, it's a good habit to get into.
FYI, I won't respond to your queries in the next 12 hours since I need to have my sleep, you know. It's nearing the darkness of the night in my side of the sorld. Thanks for your understanding. Speaking of thanks, hit the "THANKS" button if I helped you. I spent a lot of time typing this up!

So you want to downgrade to .15.3 from .27.5 with a locked bootloader. Okay, thats easy because thats what I did to get root after I lost it to a OTA update.
DO THIS AT YOUR OWN RISK-I TAKE NO RESPONSIBILITY IF YOU ACCIDENTLY BRICK YOUR DEVICE!!!!

Root & TWRP Lenovo Tab 2 A8-50F (MT8161)

Root & TWRP Lenovo Tab 2 A8-50F (MT8161)
Ok so this is a in depth tutorial on obtaining root and installing twrp for the device in the title. Anything in "quotes" eg, type in cmd "adb devices" quotes should be ignored. This guide is for those who know what root is and know there way around windows and Linux. If you did something wrong i am not liable and maybe you should have read things before trying.
EDIT: for those of you who want to root in one or two clicks i have added support for this device in the ZEUS TOOLKIT wich will root without installing custom recovery.. LINK >> http://forum.xda-developers.com/showthread.php?t=2644166
REQUIREMENTS/DOWNLOADS:
-Windows PC & Linux (Ubuntu. virtual box would be fine although i have my pc dual booting both os's)
-Driver Signing Disabled on Windows 7 and above
-Device Drivers
-SpFlash Tool (including scatter file)
-Adb Tools
-TWRP + SuperSU Files
-Insecure Boot.img
LINK FOR ALL REQUIRED FILES >> DOWNLOAD << DOWNLAOAD AND EXTRACT TO DESKTOP
Downlaod all of the above and extract/move everything to a folder which for this guide i will assume will be called ROOT on your DESKTOP
SOME READING:
The Lenovo Tab 2 A8-50F is a rather locked down device with the ability to reflash the stock rom on every reboot if required. In this guide you can only do things in a specific order to be able to get it rooted and stop the stock recovery reflashing. It took me a few times of (soft)bricking my device before i could get it sorted to a stable rooted system with twrp installed. TWRP recovery was not built from source by me personally (it was obtained from a russian website) although i have had to modify the TWRP image as it was boot looping but its sorted and working now. So roughly this is how things are going to go, we will use SpFlash tool to readback the system partition, then use linux to modify a file in the system.img the use SpFlashtool to refalsh the modified system.img. Then we are going to unlock the bootloader and then flash an insecure boot.img along with twrp and then root using chainfire's latest binarys.
THE GUIDE:
STEP 1 - installing the drivers
For this i will assume you you have already got adb driver installed if not please google it i personally used googles generic adb driver.
Please make sure you have disabled driver signing for windows "GO HERE". Now open device manager and right click on your pc's name at the top of the list and select add legacy hardware > click next > check "install the hardaware that i manually select from a list (advance)" and click next > highlight "show all devices" and click next > click "have Disk" > click "browse" > browse to the desktop\root\MTK Drivers all windows\ and choose the folder to match your windows installation and then choose the 32bit or 64bit driver file depending on your windows install > click open > click ok > highlight "MTK USB PORT" > click next > click next > if a warning pops up click install anyway > click finish. Your drivers are now installed for spflash tool to recognise your device.
STEP 2 - backing up system partition
Make sure your device is truned off and disconnected from your computer. Open SPFlash Tool form "Desktop\ROOT\SPFlash_tool\flash_tool.exe" > click "scatter-loading button > browse to "Desktop\Root\ and open MT6735_Android_scatter.txt > click the readback tab > click add > double click the entry which is now listed >browse to "Desktop\Root" and in the filename box type "system.img" > click save > check "HEX" > for region select EMMC_USER > for start address type "0xb000000" > for length type "0x74000000" > click ok > click readback. now with your device turned off connect the usb and the SPFlash tool will begin to backup your system partition to "Desktop\Root\system.img" wait until its finished and continue to the next step.
STEP 3 - editing the system.img
Now we have the system.img transfer it via usb (or whatever means) to your ubuntu machine place system.img in your ~/Home/ folder eg. ~/Home/System.img now open a terminal by pressing CTRL + T > type "mkdir output" press enter > now type "sudo mount -t ext4 -o loop system.img output/" press enter > type your sudo password > press enter > type " cd output" press enter > type "sudo mv recovery-from-boot.p recovery-from-boot.bak" press enter > type "cd" press enter > type "sudo umount output/" press enter. The system.img has now been modified and can be transfered back to windows. Goto next step.
STEP 4 - unlocking bootloader
With device booted to android and usb debugging enabled open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot bootloader". Your device will now reboot into fastboot mode when it displays "fastboot mode in the bottom left of the screen type into cmd "fastboot oem unlock" > press enter > screen will change and ask you to confirm do this by pressing vol+ > wait and when a screen with three boot options appears DO NOTHING and go to next step.
STEP 5 - flashing insecure boot.img
Now you should have the ability to flash the boot. Type into cmd "fastboot flash boot boot.img" the device will let you know it is done and when it is done flashing just type into cmd "fastboot reboot" and let the device fully boot and goto the next step.
STEP 6 - flashing modified system.img
now open SPFlash tool again it should have remembered the scatterfile if not reload the scatter file. In the main window of the download tab make sure ONLY system is checked then in the location colum click the space in line with system and browse to your modified system.img and click open. At this point before doing anything make sure your device is turned off and not connected to the computer in any way. Now click Download in SPFlash tool then connect your device via usb while turned off and the tool will begin flashing the system.img wait until it is finished and a green tick appears in flash tool and if your device does not boot automatically then unplug it and reboot it wait until it fully rebooted and goto next step. You can close flash tool for now.
STEP 7 - flashing TWRP recovery
with your devfice now booted with a custom boot and system image open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot bootloader" > press enter your device will boot into fastboot mode again when it has type "fastboot flash recovery recovery.img" > press enter > when its done type "fastboot reboot" > press enter now wait for the device to fully boot and goto next step
STEP 8 - flashing Supersu by Chainfire
Now your device has rebooted it will be missing the super user app and all binary's so open file explorer on your computer and copy the SuperSU-v2.46.zip from the ROOT folder on the desktop to the download folder on your device after doing that open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot recovery" > press enter. Your device will now reboot into TWRP recovery check the little box and swipe the arrow at the bottom to continue now touch install > touch Download > touch SuperSU-v2.46.zip and finally swipe to install. when it is finished reboot. Hey presto one rooted device with a fully working twrp. reboot and download busybox from play store and install as some programs like system app remover need some binarys from busybox.
After following the above steps you will have a fully rooted device wich can be backed up via twrp and flashed via twrp. now i have figured this out, i think its someone elses turn to build a rom for it preferably Cyanogenmod Thanks for reading this guide and all the best luck with your new rooted device. please remember to click thanks.
​

Have you found a way to root it without the need for Linux?

Hi
I would like to know if this guide will work for MT-8735
Thanks in advance,
Dimitris

Anyone found a way to root MT8735 version A8-50L or A8-50LC?

The files seem to be missing...
Any help would be much appreciated. I used the guide fine up until the Step 5.
Now I'm a bit stuck.

I used something called Kingroot along with the info and files found here https://forums.lenovo.com/t5/Androi...-to-root-TAB2-A8-50-WiFi-version/td-p/2181021 to help me root without using linux. There is a ROM listed there. If you use Kingroot.apk, you'll have to run it 2 or 3 times to get the ROOT to stick, then you can enable debugging, and oem unlocking in dev options. Afterwards, you can use fastboot to unlock the bootloader and once that's done, use the SP Flash tool to download Max Choen's rom to the device, install SuperSU and Busybox and your gravy!!!

what files? that post does not have any files provided and could someone upload the files that are missing from the post so we could also use them?

If you guys read the entire post in the link I sent you might be able to get where I got. I'm not a dev and not much for writing tutorials but my process went,
1. KingRoot
2. Unlock boot loader
3. Flash twrp via fastboot or flashify
4. Factory reset
5. Reinstall King root and re root.
6. Format and partition memory card
7. Install apps2sd
8. Install Xposed
9. Install obb to SD module
10. Enjoy tablet with 64gb of space with tons of large data games installed!!!! (Note that this step requires you own a 64 gig memory card)

I will post it in the morning, I think it's on my wife's laptop. The link I posted USED TO lead you to a post that had the files I mentioned and the process I followed. Now they are just suggesting you simply root using Kingo... Which is fine and dandy but does not give you the ability to format your memory card. I will post my recovery image for yall in the morning. You would just have to use KingRoot and then flash TWRP using Flashify once you have a successful root. Then you can format your card and install apps2sd of your choice and xposed with the obb2sd module! That's what I got going on, got TONS of large data games on the tablet cause I installed a very fast 64gb memory card, and BIGGITY BAM!!!! Turned this little budget tablet into something decent for the kiddos! Just wish we could do something about that terrible 1gb of memory, but hell, I was able to get this far so I'm pretty happy!:laugh::good:

Here it is!
Had some things to take care of first. Got a wife and kids to care for before I do my geek stuff. This is not a flashable zip! You must unzip the .img file and use Flashify after a successful KingRoot.
P.S. all credit goes to the original creators of this build of twrp I originally obtained in This Very XDA post we are conversing in! All I did was download this file, I am not a dev andi do not take credit or responsibility for any of the files I've used to root this device! Cheers!!!!

Okay... Thanks. I have SuperSU installed and working. TWRP installed and working, but I haven't unlocked the bootloader.
Will this prevent me from installing xposed framework, do you know?
And the which apps, by which developers, do you install to move apps to SD card?
Thanks for your help!
Sent from my LG-D852 using Tapatalk

I am using Link2SD, Xposed OBB2SD module. That's about it. Not sure if bootloader unlocking is even necessary for anything.

Can you flash supersu from stock recovery or do i have to flash twrp first?

I used KingRoot (ver 4.8.2) to root my Lenovo Tab2 A8-50F Tablet.
I used KingRoot as part of a SuperTool. The SuperTool, using a batchfile script, also removed KingRoot after the tablet was rooted and then installed SuperSU.
The SuperTool (April 6, 2016 version) was created by xda's RootJunky for the Amazon Fire 7 5th gen tablet, using KingRoot and SuperSU, but it rooted my Lenovo Tab2 A8-50F Tablet, uninstalled KingRoot and installed SuperSU, all with only a couple of mouse clicks.
Even if you are already rooted with KingRoot, you can use this tool to uninstall KingRoot and install SuperSU. (Just run the tool, let it re-install KingRoot, don't run KingRoot but hit Enter on the SuperTool to then uninstall KingRoot and install SuperSU).
Lenovo Tab2 A8-50F Tablet info:
Model Number: Lenovo TAB 2 A8-50F
Android version: 5.1
Kernel version: 3.10.65
Build number: A8-50F_S000037_151023_ROW
Software version: A8-50F_151023
Hardware version; LenovoPad A8-50F
The SuperTool batch file script rooted the tablet with KingRoot and then uninstalled KingRoot and installed SuperSu.
I have since installed ES File Manager, Titanium Backup, Link2sd on the tablet. Root is totally working. Rooted with only a couple of clicks!
Just enable Developer options on Lenovo Tab2 A8-50F (by tapping tablet Build Number 7 to 10 times [Settings, About Tablet, Build Number (tap 7 to 10 times)]), enable USB debugging on Tablet in the Developer options settings.
Connect Tablet to Windows 10 with a USB data cable (I used the USB 2.0 port). When screen message on the Tablet mentions connections, make sure it is in the MTP mode.
Extract RootJunky's SuperTool Zip file to the Windows 10 desktop.
Run RootJunky's SuperTool (Amazon-Fire-5th-gen.bat) You may have to read the instructions on the pages below and install adb drivers. Pick option #6 Root. Choose Option #3: version 5.1.2. This will run a script that installs KingRoot, allows you to run it manually, and then removes KingRoot and installs SuperSU.
Press enter and KingRoot will be installed on the Tablet from the SuperTool. (approve any messages that appear on Tablet screen) Now don't touch the PC SuperTool until the Tablet is rooted.
Open KingRoot on the Tablet and run it. You may have to run KingRoot several times and the Tablet may reboot. Just keep running KingRoot until the Tablet is rooted. After KingRoot reaches 100%, then press ENTER on the PC.
The SuperTool will now uninstall KingRoot and install SuperSU on the Tablet.
Choose NORMAL SuperSU install on the Tablet when prompted. When SuperSU is installed, reboot the Tablet. Disconnect data cable.
After reboot the Lenovo Tab2 A8-50F Tablet is rooted. There will be a request by SuperSU to upgrade. Approve it. You can now install Titanium Backup, Link2sd, ES File Manager, etc. Your Tablet is rooted. As easy as that. THANKS ROOTJUNKY!!!
