Ok a couple of months ago I bought 3 of these tablets refurbished. I bought them to sell them. I sold the other two, except the third one. I just turned it on a couple of days ago and it won't go past the blue screen that says "Gentouch 78" After pressing the reset button a couple of times, i got it to go to the black screen with the little penguin on top left. And it would switch between that and black and white bars across the screen. I just need it to functional normally. I don't think its a hardware issue, as the screen seems fine. Anyway to reset or flash it to factory? I tried the reset button. Also, I can go into fast boot mode, but I have no clue what to do from there.
