Got a question about the tablet. I experimented a bit with the settings and I adapted the tablet one file in ROM (Data / system / etc).
Unfortunately tablet not move, you will only android logo and then nothing. In recovery I got, I gave wipe data / factory reset and wipe cache partition but without result, that result is the same.
Is there any way to copy or modify the edited file in ROM?
I suppose some way by cable and ADB, Google wants to help me somehow ...

Firmware unfortunately I do not and I did not find him anywhere.

It is a tablet with Rockchip RK3188 3Q

Sorry for the translation...
