This should work on all Qualcomm Snapdragon based Samsung galaxy SIII's, if it doesn't, PM me the model and I'll try and find a solution.
WHILE THIS IS VERY LIKELY TO WORK FOR ANY BOOTLOADER/MODEM/FIRMWARE BRICKED PHONE, THERE IS NO UNCONDITIONAL GUARANTEE THAT THIS WILL WORK FOR YOUR PARTICULAR SITUATION, THERE IS A POSSIBILITY THAT THERE ARE SOME BRICK STATES THAT THIS WILL NOT WORK FOR, but in my experience, almost all cases can be resolved by rewriting the sdcard with correct partitioning.
Disclaimer out of the way, let us begin.
Needed Materials and Files:
EDIT: if you have another phone or know someone else with the same phone have them run this and the output will be a debrick image you can use: busybox dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1M count=200 if it does not work then change the last number (count=) to something larger and try it. If you create an image please upload it so I can put it into a repository I'm creating
16GB or 32GB class10 microSD card
A hard bricked Samsung galaxy S3 US Cellular
The debrick image for your device:
[[Here is the drive image for a folder containing all the debrick images that I currently have uploaded, more will be coming: https://drive.google.com/folderview?id=0B612qYHFMILfWUlMTTEwdUstcXM&usp=sharing ]]
If you have any images that I missed, please send me a link or, better yet, upload them to drive, make them publicly shared, and share them with me at [email protected], I will put them in this folder for all to use

---I did not upload these images, I have simply collected the links over time, please thank Cnexus for his help in finding these and
---helping me to originally unbrick my S3
Your computer
A card reader that will accept the card (another phone will not work as this is an image, and it needs to repartition the SD card)
Either a partition editor (I've heard that you can use dd or something on linux, but I haven't tried) or this: View attachment win32diskimager-v0.9-binary.zip
A wall charger (computer charging isn't as reliable)
Procedure:
1. Take the sdcard and insert it into your computer
2. Download the mentioned image and the software to put it onto the sdcard
3. Use your computer to pull the data already on the card onto your computer hard drive, as the sdcard will be wiped when the image is put onto it
4. use the software that you downloaded earlier to burn the image to the sdcard
5. Remove the battery from the SGS3
6. insert the sdcard into the S3
7. Put the battery into the S3
8. The S3 may boot automatically, or you may have to manually boot it by holding down the power button for 5< seconds
9. If the update that bricked your phone also messed up /system, then you'll have to coerce Odin mode to shove a stock firmware image to your phone, though I've had more than just SOME trouble with that in the past (in other words I haven't been able to get back to stock yet...), if you simply had a radio update or something go wrong, then proceed to the next step.
10. Do a victory dance with your phone in your pocket not the repair bench, or on second thought, make sure you don't drop it, don't create another problem.
11. After that, you can just use your device normally with the sdcard in it without worry of bricking it, though it will not be able to boot if you remove the sdcard;
the only known method of getting it to boot without the sdcard is reflashing stock firmware, which completely wipes the phone and resets everything back to complete stock. Also, Odin mode has, at least for me, objected when I've tried to flash the stock image back onto it, and even if Odin mode was sure of working, backing up ~16GB of data isn't a fast process, especially with the most reliable means being ADB. If you try to flash a stock image and it fails, your device will almost definitely come up with a version of dmode when you try to turn it on with the sdcard (still bricked otherwise) that says something about Kies update failure, the only way of correcting this that I've had success with is flashing an image that won't do much, such as the same recovery that you already had, over odin mode from that special dmode, as while that won't correct the actual brick, it will at least make you able to boot from the sdcard again. I will provide links to the stock images in a little while, once someone gets that far, as I will have to find all but the one from the US Cellular version.
I am currently looking for firmware images that will only flash the bootloader/modem, if anyone knows of an odin file that could do that, please let me know as soon as possible, in the meantime, I will try and create an update.zip that will flash the necessary files; as most bricks are likely cause by an update.zip that was meant for a different device, I am very confident that it can be fixed with another .zip file.---Stay tuned!
---Don't forget, that thanks button won't bite your finger off if you push it:fingers-crossed:
If any of the links are not fully functional, PM me to let me know, and if you have the link to another debrick image for another device, send me the link so I can include it here!
Please note: While there is a similar procedure for Xynos based S3's, they apparently require a physical modification that requires an amount of soldering, so it is most likely best for them to simply take them in for Jtagging and then just not brick them after that.
EDIT: here is the link to a full youtube tutorial that I made, just for those of you who like watching a video instead of getting lost in a written guide https://www.youtube.com/watch?v=-RTAbLBVfMI
EDIT AGAIN: I'm sorry about both of the mediafire links being down, I will try and find some more and upload them to my google drive, along with the others just to make sure they exist somewhere safe.I'm downloading the images now and uploading some that I already have, they will be available in this folder (https://drive.google.com/folderview?id=0B612qYHFMILfWUlMTTEwdUstcXM&usp=sharing) on google drive and will be available by email upon request

If you want to get your phone to operate without an sd card in there for every boot, stay tuned, I'll have a guide to return to stock soon, though a quick google search shouldn't be that hard if you're desperate
I will clean up this guide in a little bit but currently I have school and such to attend to so it may not be immediate
I know this is getting unwieldy but (big thanks to youdoofus) I have a way to completely debrick and fix it so it doesn't require even the sd to boot.
"Restoring stock bootloader
1) You were able to boot into the ROM
2) Plug your phone into a computer and use MTP mode
3) Move the debrick file onto your internal sdcard (/sdcard/debrick.bin)
4) Disconnect your phone
5) Open up a Terminal Emulator on your phone and input this code
Code:
su
dd if=/sdcard/debrick.bin of=/dev/block/mmcblk0
6) Reboot"
Of course this should be modified for the different versions and types of debrick image as some are img, some are bin, I think there might even be an ISO hanging around somewhere
EDIT: As of October 10th I'm working on a tool that will get an image directly from a stock rom/tar and put it on the SDcard. This is pretty complex so it will probably take a little while, but it should make it easier to get images if all that's required is a stock tar.
I've followed all these guides and haven't had any luck. I did use a CM 4.4 rom and some people are saying i need a debrick.img of a 4.4 to get it working again. i'm on an i-747. can you help?

You don't need a debrick.img of a 4.4 to get it working, you need a debrick.img of the correct bootloader. If you bricked your phone by flashing an older bootloader after upgrading to the 4.3 bootloader, then you need a debrick.img with the 4.3 bootloader.

Explain your situation. Randomly bricked is very vague. Did you flash anything? Do you remember doing anything? It's important. Phones don't go and "randomly brick" unless of a HW problem, and to either confirm or eliminate that possibility we need more details.

Like i said, it was totally random. My phone froze and rebooted yesterday. It got to the Samsung logo so i thought everything was okay. I fell asleep and woke up to a bricked phone. After all of my attempts, I got one debrick.img to show something on my screen and it shows "BOOT RECOVERY MODE". Odin sees my phone and tries to fix the PIT and the Bootloader but it always fails. From what i gather, it seems to be a hardware issue.

Whoa whoa there, if your phone still boots in either recovery or download mode, then you don't need to use a debrick.img.
If you have a custom recovery, you can flash your custom rom. If you don't, you can flash a stock ROM using ODIN in download mode.

It is hard bricked. Without the sd with a debrick.img installed, I get no response at all. And I've tried all the i747 debrick.img files I could find here with no success.
I can get to boot recovery mode with one .img I could find but boot recovery os different than recovery mode. It's essentially useless and Odin doesn't like it.

It really sounds a lot like the BRICKBUG to me, anyone know how to tell if a chip is insane without it working? And did you have the 4.3 bootloader? If you got that you should have been safe, but if you didn't then the kernel may have burned out the chips from the "bug" (it really doesn't seem too much like a "bug", more like an issue worthy of recall)
Sorry I don't know exactly what's wrong off the top of my head

If you get ANY response at all, then the debrick image is doing its job; what you need is a stock image, I'll try to find a link for you to use. Try using Kies or something, alternatively, as if you have the serial number you can apparently flash it quite cleanly, all data on the phone will be lost though, as it effectively wipes the eMMC.

Exactly
This image gets you in the clear if the ONLY thing screwed up is the boot partition, meaning modem/firmware/bootloader, it does NOT get you fixed if you got your rom F***ed up, and do not expect it to, this will get you into dmode so you can use odin or something like fastboot to flash a /system image or a FULL stock rom if you want to get your bootloader fixed without the SD card being in all the time.

if anyone can find the correct debrick.img i need to use, i would greatly appreciate it. I have tried Kies and Odin without success. They can see the phone but seem not to be able to access it. I can't flash anything via odin or get to the CWM recovery or download mode. this is a really weird screen i haven't seen before.

If you bricked the /system partition AND the boot partition you will need a stock rom as well, just use Odin or something if possible after using a 4.3 image, a 4.4 image is more or less the same as a 4.3 as far as I know, I mean I bricked mine after using cm11 by flashing the wrong rom, it's just that the rom you tried tried to flash a 4.1 bootloader, and thus tripped the eFUSE or something in the Knox bootloader, what you need is a 4.3 unbrick image, as 4.4 didn't really change the modems/bootloader from 4.3, and the unbrick image isn't really that much more than a collection of pieces from the boot partition that are used as an autoboot by the phone when the eMMC fails to load properly.
This is pretty neat..
does it always work?
It's nice to have such a recover method whenever something like this happens to you.

I believe it will work on basically anything, as in I haven't seen a case that can't be cured at least somewhat by this, I think it works like an alternative boot, as if the bootloader on the eMMC is corrupted, it seems to remove the boot flag, thus making it so that the phone does not detect a bootable partition, the unbrick image has a partition layout mirroring the one that is supposed to be on the phone, so it is used as the boot partition but then redirects control back to whatever is on the eMMC after the bootloader, think of it as a liveCD on windows, just one that hands control back to the system after it has gotten past booting the BIOS.
I was trying to find a custom recovery, or any recovery that will work on my lg realm. I boot recovery and it gives me a error message so im guessing its either wiped out or blocked...any ideas out there on how to correct or replace it

Looking for one as well. I have not found one.
Recovery is actually preinstalled
I found this just tooling around. Use your favorite file browser, I used
Total commander. /system/vender/itson
The zip file is there. Hope this helps. (Rooted LG ls620)
Could you explain in a little better detail on what you mean Enigmatic177... I'm pulling my hair out Hehe
If anyone makes or finds a working recovery please post it.
Itson is a zip file that was installed after last update it has the basics to unlock the boot loader. I unpacked it used Rom toolbox pro rebooted to RECOVERY did regular reboot system upgraded.
A couple if bit mapp errors 11111. Then I basically flashed CWM.
Before you do this the partitions change from ext2-ext4. I'd advise
Backing them up.

TWRP recovery help L620 LG Realm
hello I followed the steps in the read me file and i succeeded in installing twrp although im having troubles booting up to my system os. when i power on my device it takes me straight to twrp. i have a feeling i might of missed a step. i tried creating a backup but i cant because i noticed my screen turns off fast. do you think you might know what might be the problem why i cant boot up to my os? thanks!
I think i know what seems to be the problem. I think i might have accidentally replaced the boot img with the twrp recovery img. i did not make a backup before this happened. is there anything i can do to make my phone boot up to its normal image? thanks
Nope. It is officially a paperweight and no one I know of has access to the stock ROM either.
Sent from my LGLS620 using XDA Premium 4 mobile app
Hey
Has anybody found a custom rom?
Finally. Easy as pie
Ok, I downloaded an image (w5c_twrp_bumped.img)
put that img on the root of my sd card
downloaded Rashr from the google play store
opened rashr and tapped 'recovery from storage', navigated to external sd and tapped the image and tapped
ýes please'
flashed it. after the flash the phone rebooted into the twrp recovery.
then just rebooted back into the system
worked perfectly.
im new here im not allowed to post outside links yet, just google "w5c_twrp_bumped.img" should take you to a link for a download of that recovery
i got twrp now as a custom recovery. on my lg realm.

You have the bumped recovery so all i can say if u messed up is to flash a stock rom u can find on google i had to re flash mine a few times messing with root
right on, thanks for the info. I had no problems at all. it all fell in place like i was hoping. The Realm is the easiest device Iv ever rooted, flashed, and messed with. Well, as far as rooting and flashing a custom recovery. dunno bout roms though. Im sure its simple?

OK, I grabbed and extracted this. I used Flashify to simply flash the recovery (w5c_twrp_bumped.img) and it works like a dream on my LG Realm.
OTOH, trying the same on an Exceed 2 gets me TWRP, but it cannot mount much of anything and the backup fails. After failing, it tells me "No OS found, continue?" I continue and get the message "Appears your device has no Root, install now?' I am absolutely certain I have root, or wouldn't even be able to run Flashify, so I continue and it simply boots into the OS just fine. Perhaps the readme isn't complete, as I see the following file in the extracted folder (resources.zip) with no explanation of why it's there. It "appears" to be a flash-able zip that installs "itson" (whatever THAT is). Note that the Realm has this in the /system/vendor/itson, yet the Exceed 2 doesn't.
Have you actually used this on an Exceed 2? And if so, what am I missing here?

I'll do you one better. Just forget about the post you replied to, as it's convoluted as hell. Install TWRP 2.8.6 from here. Ignore the big red warning about the Realm, as he evidently hasn't updated the OP. You can view my notes regarding the Realm in this reply. Tested several times and verified working better than anything else available. Easiest recovery to install I've ever dealt with (all done with an .apk). The option to access via cold boot (battery pull procedure) is something to behold
Be sure to thank the developer, even if you need to create an account to do so. Very VERY nice work!

Before you replied I installed the version 2.8.5 from here:
http://androidforums.com/threads/twrp-2-8-5-0-for-realm-ls620-and-exceed-2-vs450pp.908704/
Is 2.8.6 better? Looks like the 2.8.5 can't be booted into via key combo from power off? Are there any other differences? I just used the Rashr flash tool from the market to flash 2.8.5. Worked flawlessly. This is actually my mom's phone and it wanted to do a system upgrade but I wanted to back it up first so that's the reason I wanted a recovery.
Pretty cool though, this recovery installs just via an APK!!!? That's amazing!
I'm tempted to install this on her phone next time she comes over... it should be fine right?

That one will cold boot with the battery pull procedure too. A little further down that thread you'll see I modded it to work correctly with the Exceed 2 in addition to the Realm. I like the 2.8.6 better if only that the dates of the backup are correct now. The 286.apk will work fine and overwrite your current recovery. If you leave it installed, you can always open it and reboot to recovery from within the app. If I have more time I'll post a screenshot, but running late for work. I think the screen dimming/timeout issue was fixed as well, but I haven't verified that. I normally disable that in TWRP anyway, as I like to monitor what it's doing during a backup/restore in case of errors.

Just got this same Tab for my son & have been looking around for the best ways to root. It's actually a nice little tablet. For $65 I'm quite impressed.
Couple questions for you if I may.
-Does this download have any prerequisite downloads, surveys or ads before it's installed on my PC? You know, junk & not just the program.
-Which super user app is installed?
Kingo root comes with all the files you need with no surveys or bloatware. It installs its own super user program but I deleted it wit ha system app remover and installed super su from the play store. If you can, after you root your tablet can you pull the stock lenovo launcherHD and upload it to here. I deleted mine and you need it to change the lock screen wallpaper.
hI guys!
Good to see topic about our tab 2. Small question - any1 of you got lolipop update already? Week ago Lenovo said it's ready... I have so annoying touch bug and hope update gonna fix this.
The update is not out yet but lenovo said late summer so I would think it would come out sometime in august. Once it comes out can someone try kingo root on it, I'm not updating if I can't get root.

Well I tired to get a recovery on the tablet but failed. Mtk tool and sb flash didn't work since the tablet is write protected and also I don't think is works for media tek 8 series chips like it does with 6 series chips. I was going to build twrp but you need a unlocked bootloader to flash it and when I run fastboot OEM unlock it returns three dots. I think my fastboot drivers got messed up after I unhard bricked my OnePlus and that's causing it to return 3 dots. I will try another pc and report back.
Nope it still returned the three dots. Well I'm out of ideas to unlock the boot loader. Maybe a more experienced dev can do it or we can ask lenovo nicely.
Bootloader
According to a thread on the lenovo community... the device has a mediatek proceesor, which can be flashed without unlocking anything using their SP flash tool. Only downside is any custom roms would have to be built for mediatek and using a "scatter" file.
Thread: forums.lenovo.com/t5/Lenovo-Android-based-Tablets/how-to-unlock-the-Lenovo-A3000-bootloader/m-p/1588718/
Stock Rom: androidxda.com/download-lenovo-stock-rom-models

The rom's source is also available on the Lenovo support site.
Unfortunately, I'm not expert at anything to make anything happen with this information.

Then again, all that may have nothing to do with the A3300, since it's all based on the A3000... but same processor type? doesn't seem like mediatek has any info on their site about it either.

It was like pulling teeth, but I FINALLY got TWRP running on this tablet. It was EXTRA painful for me because the tool I use asks you to select your device resolution and like a dummy, I actually picked 1024x600 (which is the device's resolution in landscape, but not portrait mode.) When the thing finished installing TWRP and booted up, I was locked out of the tablet because the touch elements for twrp to actually restart or even unlock the device ran off the screen making using them impossible. I had to wait seven hours for the battery to finally die before I could access the thing again, (thanks for skipping the reset button on the a7-30F, Lenovo!)
In a nutshell though, I started with Kingo Root, which was successful, and then used Easy Magic TWRP Installer made specifically for mediatek devices, found on another xda thread. JUST MAKE SURE that when it says "Unable to detect your device resolution" that you choose the highest res below 600x1024 (it was like 546x964 or something like that. I can't remember exactly.) After I had a working TWRP, I switched to chainfire's SuperSU
I hope this helps.

Let me know how it works...
The biggest challenge with installing a ROM methinks though, is that you have to use the SP Flash tool to actually upload a rom. I could be wrong... I haven't tried through TWRP. It took me so long just to fix my screw up that I put it down for a while. The SP Flash Tool needs some kind of Android Scatter file, (probably a Lenovo specific MT8127_Android_Scatter.txt), which I have been unable to find or figure out from the source. I'm just not that talented.
It IS entirely possible that just applying a rom via TWRP will work fine, but it's also likely that the system will bark at you. I'm curious to see what happens.:good:
Usually you can get the scatter file for mediatek device with mkt tools but the option is blocked out when I plug the tablet in. I downloaded the cm source but I ran into my first hiccup when I use cat /proc/mtd to extract the boot.img it won't show any of the partitions.

Yeah, I think the mtk tools app is unable to access the root shell on the device for some reason, keeping it from being able to grab the scatter. I'm not sure why it's not working though. I got SuperSU installed and running on the tab, but that application still fails to get to the root shell.
I can't find any time to work on porting cm to the A7-30; Can anyone else give it a shot.?

It was dumped into the 'last_log_r' file from my last update. Then today I downloaded the lollipop OTA and pulled the scatter file from that (this is what I attached here).

How is the update? Is it worth it?
Hey guys!
To start, I want to say what an amazing place XDA is and how much information and knowledge you can get from here and how awesome the moderators are. I don't think I could ever find another amazing and/or helpful community such as those found here! Thanks to all who have helped me out with my Android issues!
Now to my issue and I apologize ahead of time if there is another thread (or related thread) found in the forum.
As the title states, I have a 2013 Motorola Moto G XT1031 Boost Mobile device. I had upgraded it to Lollipop 5.0.2 or 5.1 when it came out (I can't remember which one it was) and I had then decided to root it. I can say that I believe I was successful in rooting the device because I was able to install Supersu and use RootChecker to verify the install. Everything was going okay until i decided to research and eventually install a custom recovery and attempt to install a custom ROM. Well, let's just say that the recovery install was a bust...
In doing my research for a custom recovery, I found that TWRP had a custom recovery for my phone and apparently for my firmware via TWRP's app on the Play Store. So, I searched for my device in their in-app search for a custom recovery, downloaded it and installed it from the app. Now, my gut told me that this probably wouldn't work and that I should probably be installing a custom recovery via CLI. Nope. I didn't do this. Instead, like I said, I installed a custom recovery from the app itself. That screwed things up for me. I have no idea if it was the install, but my phone began to act incredibly strange. When in the TWRP recovery, my screen had this line that would continuously scroll from top to bottom. It wasn't a completely solid line, but it was transparent, almost like an empty thermometer glass stick was going down the screen. It was weird and not normal. I figured the phone's software was partially broken. It only did this in the TWRP recovery. Nowhere else did this happen. It was slightly annoying.
Later on I decided to install a custom ROM. Again, I did the necessary research to find out if there were any ROMs available for my phone (using XDA of course and others) and found that there were a few out there. So, I downloaded one (wish I could remember which one) and attempted to install it...keyword there. After attempting the install, my phone would not boot. Like at all. Dead. So back to the drawing board I went to try and reverse the damage. Using XDA (ironically) and a plethora of other sites, I tried to resurrect my phone and bring it back to life. After countless hours of trying and trying and trying and more and more research, I just gave up. The phone is dead. Great. $170 spent on a phone to break it a year later.
It's been roughly 4-5 months since I have attempted to redo the process and after another minor attempt, somehow I was able to remove the root completely, including the custom recovery and ROM. I don't know what the heck I did, but it worked....sort of. The phone is now stuck in a bootloop on the logo and sometimes the "bootloader has been unlocked" screen when try and factory reset the phone from the default recovery. When trying to reinstall the stock firmware, I read everywhere that I need the phone to have USB-debugging set and to have this and that. I have this and that installed on my PC, but obviously cannot enable USB-debugging which is needed for ADB and fastboot to recognize my device.
So, my question for anyone who would like to help me out is this: what are my options? Is the phone recoverable? Is there any way I can get ADB/fastboot to see my device and finally install the stock firmware on the phone? I have the proper drivers installed and ADB/fastboot are on my PC. Any help would be amazing, even if you have to tell me to junk it.

This is incorrect, where did you read that? To reinstall the stock firmware using fastboot, you must be able to boot to the bootloader menu only.
I heard this from a few websites actually, although I could never find a situational fix for my phone. I am trying to restore back to Lollipop without a custom recovery, because within the past hour I found out TWRP was never fully removed when I tried booting into recovery from the AP Fastboot menu when doing to power+vol down option. The TWRP logo shows for about 10 seconds and then the phone tries booting normally, showing the unlocked bootloader warning.
So, yes I can boot into the bootloader menu all day long with no problems. It's just an selection I make doesn't get me anywhere. My question I guess now is: how do I go about reinstalling stock firmware via the bootloader menu. I have Minimal ADB and Fastboot installed on my PC. If I need the full ADB, I can download that. And of course I'd need the firmware, too.

I am trying to follow the steps listed here http://forum.xda-developers.com/showthread.php?t=2542219&page=35 and for some reason I cannot run any of the commands pertaining to the sparsechunks. This is what I get:
Is there anything you could tell me about that?
Edit: I was able to figure what the issue was when trying to write the sparsechunks. I had to insert a "." after 'sparsechunk' because that is how the file is named in the folder. However, now I am getting a new error, but it takes place on the phone screen. Every time I attempt to write a sparsechunk, it will initiate the process of doing so, but on the phone I'll get what appears to be an error saying, "Image is too large" in pink lettering. Why does this happen? Each sparsechunk file is at least 4MB less than the max-sparse-size according to the ADB and my phone, which is set to 256MB. Is there any way to change that?

Check which sparsechunk files you have and make sure you flash all of them in ascending order. If it still fails, copy/paste the contents of your command prompt window (no screenshots please).

I will try that. There was a ...sparsechunks.0 as well apart from sparsechunks.1, sparsechunks.2 and sparsechunks.3. Shall I include that, too?
And adding the screenshot was an amateur mistake. My bad.
@_that this worked like a charm. Phone is 100% working ans usable now. Incredibly helpful. Thank you so much!
I dunno, but I thought maybe I could make a separate thread about a possible way to poke into the LeapFrog Epic's preloader so it could accept unsigned images. LeapFrog won't spill the beans for us, as their staff (falsely) claims to know next to nothing about it, so unless we somehow managed to social-engineer them into giving us a signed ROM or an unlocked bootloader, our only chance is to patch it so it would ignore the lack of digital signatures.
What I've done so far is to run a strings check on the preloader and uboot binaries - fastboot seems watered down somehow as it lacked references to "oem unlock" and so on, but none of that Amazon Fire-style failsafe seems present from what I can tell.
Preloader: http://pastebin.com/H9QbzqC0
lk: http://pastebin.com/kSxRKYna
Boot files from the latest firmware revision are attached here, so if anyone is interested, please please please let me know so we can fix bricked units and finally port TWRP to this underrated kids' tablet.

If I may ask, how did you extract the strings from preloader and lk? Did you use a hexeditor or there is another app?

I used this utility to do a strings dump off an Epic ROM:

It did turn up some interesting stuff but I was wondering if a binwalk or perhaps an IDA disassembly analysis would do wonders so we can finally poke into this tablet.

Thanks for the tool but I cannot seem find a way to use it.
@gursewak.10 or @smartmanvartan please chime in to help us because they were able to hack the preloader of k4 note and lk of RCA Viking Pro respectively
I also know a friend who is willing to donate a spare Epic, if that helps.
As for using Strings2, the following batch script should work:
Code:
@echo off
strings2 %1 > test.txt
pause
Just drag a binary to be analysed into the batch file, and a resulting text file with strings and stuff should be generated.
Hello friend
You need to tweak lk to unlock bootloader . i am giving you my phone's both files(.you can easily compare them.
on unlocked bootloader u can flash unsigned images via write memory option of SP flash tool .
Try HxD hex editor

Hmm, I can flash the preloader to my leapfrog via SPFT, but not anything else. Write memory works, and I can flash stuff one at a time to it, but I couldn't get the tablet to force itself out of flash/download mode and into normal mode. There's no reset button, and not even taking the battery off does the trick.
However, on my working Epic, I can alter the demo system image, flash it back using Write Memory and still end up with a working device, just as long as the preloader isn't messed with in any way. Right now I am at a loss as to how to revive my other Epic, short of taking it apart and shorting KCOLO and GND. It also didn't help that the testpoints aren't labeled at all. :/
Also, I did a quick logcat while running the FOTA utility, and I managed to get a few URLs off the said logs. Problem is that while the ZIPs may be of some use, they're incremental and there doesn't seem to be a full scatter/zip image to restore a faulty unit. There definitely needs to be a way to patch the bootloader so we can do whatever we want to it, but is there any one of you guys who are experts when it comes to MTK modding?
Any more ideas?
Anyone, please?
Bumping in case there's anyone interested in poking into this.
Now this is interesting let us see what we can do.

You happen to have an Epic with you? Please let me know if you need more than just the firmware images. I've tried contacting LeapFrog regarding this issue to no avail. They did give my friend and I the kernel sources, but it's no use as the bootloader has to be unlocked for custom boot or recovery images to be used.
Is anyone willing to test if SP Flash Tool 5.1532.00 works on the Epic? I managed to flash a complete system image to a bricked Epic but I was unable to revive it as it has been bricked prior due to a botched preloader flash. The ROM's on my main Epic discussion thread, but one should take note to flash just the boot, recovery and system images and see if the device still works.

Are you able to muck around with LK or sbchk using IDA Pro or some other tool? Makes me wonder if merely deleting /system/bin/sbchk would disable boot-time checks or if there's more to it than just that.

well i tried hex editors but lk.bin isnt decoded for my rom so half of my lk file is not showing me anything exept weird characters but i can see some of the other half.
if you delete the file...will it brick?...will it even boot?
GREAT NEWS I MANAGED TO GET ROOT WITHOUT UNLOCKING THE BOOTLOADER ALL YOU NEED IS TO
1.download your firmware and extract it
2.extract the boot.img from the firmware and put it on your phone REMEMBER WHERE YOU PUT IT SINCE YOU WILL NEED THIS!
3download magiskmanager install it and open it.
4click install and choose the boot.img it will install magisk into it
5.put it back in your firmware folder on your pc
6 look for a file that says Checksum_gen and run it
7 once that completes use spflash tool and load your scatterfile and flash JUST THE BOOT.IMG wait for the reboot and you have root!
THANK YOU DEVELOPERS OF MAGISKMANAGER!
