This is my first post. I've a big problem. In my job, we've tablets Hyundai Koral 10x2, for any reason someone did a hard reset from
factory modeand now we can't pass the screen google account 'cause the person what did the hard reset forgot the mail & pass. So, anyone know how can i remove
FRP? I have not found anything on youtube or google
Tablet Data from Android Recovery:
i can't use
adb commands, from sdcard i can't install apps 'cause always shows error: Signature verification failed. Error 21.
any solution? please
Things what i do to solve the problem:
1st method: changing language to pyckknñ, insert new wifi network, long press in space key, press in green letter, click in green button, click in option with rigth row, click in three points (up|rith) press in second option, open in Switch, now in the video show a shared button this not see in my tablet (shared option is'nt visible like the video) if i touch the video, this show a shared button after i press shared this open YouTube Go at this point all looks good but YouTube Go show: please login in your google account and when i try to do it, same error: this device was sinchronized with another account. https://www.youtube.com/watch?v=pYdExc-DcGM

https://sourceforge.net/projects/rkflashtool can dump firmware off device and write single partition/offset. It is therefore capable for erase FRP partition. this https://github.com/neo-technologies/rkflashtool might help to figure out usage.
There are maybe easier methods for example https://www.techeligible.com method which is pretty generic (check https://www.google.com/search?q=rockchip+rk3126+frp )
