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

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!
