The ViolaPad 10G I got my hands on is still pretty ok I think (rk3188 Cortex A9, 2048 x 1536 resolution, 2GB RAM) but the Android 4.2.2 is behaving odd to say the least (not even recovery mode is working properly), and there are no updates from the manufacturer.

Any chance there is a different Android rom available that might be working with this device?

 I do not have much of a clue I have to admit, so far I was just using different roms for my old HP Touchpad, so at least I already did some repartitioning, flashing and so on 😉 

Addendum: Is there some one else using this device that could provide a backup of the original rom?
