Any help.

I have two Arnova 8G2 tablets, one at home, one at work. different apps installed have different uses.

Both of them today have started to do the same thing.

The Arnova logo comes up and then the screen flashes white and the tab resets.

If not connected to power (usb or charger) they will not start up.

I have tried flashing rom, took 3 attempts for rockchip tool to say updated successfully but this still did not work 🙁

Any suggestions?
