So I grabbed a couple of tablets for a project. I might just end up using the lcd panels on a pi but, I'd like to try something with the tablets first.
Trouble is the android install is corrupted. Stuck on a failed update or something.
I can't get into android to enable developer options. So I can't root and flash through fastboot.
It tried to upload img but fails. I'm assuming as I'm not in dev mode.
What I'd like to do is enable bios/uefi so I can boot into x86 os's. (Linux)
I'm pretty sure hardware wise this uses the same motherboard as the Windows version of this tablet, that has bios options.
But first step is to get dev options enabled so I can run fastboot root and flash methods.
Sooo need to repair android.
Anyone know where I can find the recovery image to put on the sdcard to reinstall from droidboot?

Guys,
I have a Freescale iMX515 A8 9.7" unbranded tablet running Android 2.2.
The software/firmware on there is f'ed up, because it doesn't have recovery mode. Since that's not all that is wrong, I need to update the firmware, but I don't know how.
If recovery mode works, then no problem, but it doesn't. So can someone tell me how to install new firmware without using recovery mode?
For info: I have a Mac and do not have access to a windows based PC. I also tried ROM Manager, which also doesn't allow me to install new firmware, and finally I tried quick boot, but that too doesn't allow me to utilise recovery mode.
As a suggestion (mind you, I'm a noob otherwise I wouldn't be asking for help here), I would expect a solution using adb shell, or perhaps just copy/pasting a clone of the internal TF card (most likely the best solution)
Hi,
A friend gave me a Storage Options Scroll 7" Model 51624 (TCC8902) with 2.1.
I found that cyanogen has a 2.3 Rom for this device so I tried to flash it.
I flashed the clockwork recovery and did my back up. Then I downloaded the rom from cyanogen and installed.
What was my surprise that when I restarted it got stuck on the main screen with the logo "scroll Storage Options"
I tried to enter the recovery but doesn't work!!!
I think my error was the rom I choose for flashing.
I used the Storage Options Scroll 7" resistive 8K, and I know now that mine is the same one but the resistive 4K.
I though I could do something if I could use the Adb commands and some inspiration but the problem is that my computer doesn't recognize the device (Android in yellow on device manager). I installed the Android SDK that has the google usb driver but still not working. I tried the VTC 5.0.0.1 drivers too but no luck either.
I desperately need some help to install the boot recovery and then I'll flash the right rom.
I use windows 7 x64 and a laptop with windows xp 32.
I've been reading the thread http://forum.xda-developers.com/showthread.php?t=1101094 but has 163 posts and I have to say that I didn't read all of them. Anyway I did a search about bricked scroll and didn'f find anything. If someone knows where to point me at I'll be very gratefull. I appologize if my posts is already solved somewhere.
Thanks in advance
there is a guide on getting android adb set up on the pc with modified drivers somewhere...
1st things 1st though, have you tried holding vol up while turning it on to get into recovery?
as long as you installed the custom recovery correctly (which im sure you did if you managed to install another rom), then you should have no problem getting into it.
unless, that is, you dont have any volume buttons to get into recovery / they dont work!

To flash the cyanogen rom I had to enter the clockwork recovery with the power+vol up. So first thing I did after realised it wasn't going to load the rom was to restart the tablet into recovery but it doesn't work.
That's why I was thinking the posibility of flashing clockwork recovery again through the adb commands or maybe the boot.img (I think this img is the one responsible for boot). But as I said my computers don't recognize the device. Both says Android with the yellow warning.
I'm looking for this modified drivers but can't find them. any web site address?
I have downloaded the firmware from Storage options but as I cant enter into the recovery I can flash it.
Hello,
I have a tablet that has recently stopped booting. The manufacturer does not provide a firmware rom, nor have I been able to recover it any other way. I feel like I have been running in circles in researching ways to recover it (but I have learned alot). I think that I could recover the tablet if I could install a more flexible recovery manager, such as CWM or TWRP. However, to my knowledge, the tablet must be rooted first in order to install these custom recoveries. So that brings mt to my question: How can I root a tablet that won't boot? I have heard many good (and a few bad) things about Kingosoft Rooter and other root methods. However, even Kingosoft requires the tablet to have USB debugging enabled. Unfortunately, I did not have this enabled before my tablet crashed. So:
1. Is it possible to root my tablet that won't boot?
2. Is it possible to enable USB debugging on my tablet that won't boot?
3. Is there any other way you can think of to get this tablet running?
By the way, the tablet is a RCA RCT6378W2 tablet. I can access the stock recovery (android system recovery <3e>, but I can't seem to make it do anything worthwhile. Any ideas? Thanks!
1. You can't root because the tablet must be on
2. You can't enable adb debugging because the tablet must be on
3. I guess that your tablet is a made in china tablet, so there should be a devices that have same or similar characteristics, and maybe there is a stock rom for those devices
Good luck for your tablet :good:

Wipe cache and reboot and when it doesn't work do you have to try factory reset.

Thanks to both of you for your suggestions.
@ bink feed - Thanks for those recommendations. Those are the normal recommendations that should be given to most people. Unfortunately, I have already tried both of those options with no success. It seems that many, many people are running into this problem. It makes me wonder if the recovery partition is corrupt or if some system files were somehow corrupted. The "wipe cache" option and "factory reset" option both perform successfully according to the recovery system, but they do not fix the problem with the tablet not booting. I apologize for failing to mention that I have tried these options. If you have other ideas, please let me know.
@ kfarhan57 - Thanks for the suggestion. This seems like a good idea and it is something I have attempted to do. Problem is, I don't know precisely what similarities must be present for this to work. I have tried using ROMs from other tablets that share the same processor and motherboard, but have not had any success. They seem to always fail the verification process. I have very, very little experience in all of this, so it's always possible that I am not doing it correctly too. Do you know of anyone who has successfully done this? (Someone who has restored on device with a firmware from a similar device). If so, I'd like to ask them how they did it. Here is what I have tried:
1. Boot device into Android Recovery System.
2. Select "Apply update from ADB"
3. Connect the tablet to PC using USB cable
4. Load up Cmd terminal in Windows, navigate to folder containing ADB.exe
5. Type in "ADB sideload filename.zip"The only thing that I have successfully sideloaded (and passed verification with) has been 3 small firmware updates for my tablet. Unfortunately, they are minor updates and do not restore the Operating System or ability to boot into the OS. Presently, I have been toying with the idea of merging one of these small firmwares that pass verification with the factory OS firmware from a similar device. I don't know if this is even possible, and if it is, I probably lack the knowledge needed to do it. If anybody reading this post has a suggestion, please let me know! BTW, one other thing I forgot to mention is this- I have the files copied from a working tablet of the same model. I have the boot.img, recovery.img, system.img, and virtually everything from his device... I just don't have a clue what to do with it. Thanks again. Hope to hear back from one of you!
Ok, so as the title says, I have the blob files (which I just found on my laptop). The tablet has TWRP v2.6.3.0 and asks for a password, which I don't know. Reading around it looks like it's just the error you get if you happen to have installed the wrong recovery for your bootloader. I have run the JB brickproof (flatline) and have my files. However, I can't get my desktop *or* my laptop to see the tablet in adb. The drivers fail. I also can't seem to get it to boot to APX mode. It only wants to go to TWRP. I can't force the BL to run because I can't get ADB to run. Anyone have any thoughts?

Try reinstalling the Universal Naked Drivers, using a different USB port, using Test Mode (if on Windows 8) to get the ADB working.
When that does get up, this thread should be helpful:

Hey todd.. I have a tab thats briked too for around 9 months now( flashed wrong twrp and on top of that chose wipe option from bootloader..my mistake for not reading the instructions clearly)and i hadnt made nvflash backup..now i am desperatly searching for the blob files so that atleast i can try doing something to get it out of the graveyard.. I never it online anywhere..I know the files are device specific but what goes in giving it a try..curretly the tab just boots to recovery with adb and apx only..fastboot doesnt work..
So will it be too much to ask if its possible to share the blob files??? ..
Can you BOOT into TWRP from bootloader using only a USB stick? Autorun the boot command with the twrp file on the stick somehow?? Ive been searching the internet but not having any luck..:good::good:
Wouldn't this create the same issue as having autorun.inf load something on a Windows PC? I find it hard to believe that many people would be OK with being able to boot to bootloader, pop in a USB, and have something run automatically. Although it would be convenient from an upgrade on the go stand point, it would be a big security risk.
