Time to set the scene. I had a stock rca tab laying around so I found the thread to a discontinued project on here. I flashed the files and could not get it to boot again. Stuck in an awesome two dog logo. Yay. So after searching a couple days for the stock files I ran across someone comparing this tab to the Cube u25gt-c4y. What do I have to lose. I searched and found the stock files and bam! I had a chinese tablet. Surprisingly it works with just a few flaws. After flashing you will see a nvram error in the wifi. Easy fix. Adb seemed finicky at first but straightened itself out. Screen rotation is also 180 degrees out. You have to tilt it down and lock the rotation. Lastly you have to change the language to english because the default is chinese. Will be trying to get the gps and fm radio working soon.
Install Sp Flash Tool if you have not already. There are many posts on this so I wont repost them.
I used the "Format and Download All" option. I have read dont do it on some threads but I have seen others that said to.
If you want TWRP then rename the file to recovery.img and replace the one in the roms file.
Installing SU from twrp when it asks works fine.
That should be it and now you have a working tab again.
As always USE AT YOUR OWN RISK!!! Nothing to risk though if your tab is already a brick.
Thank you to all the posts I searched to get my tab back working.
