The happening of the problem only lies in the system update process is canceled.
Now,
While I use a USB cable charging process, the power light is flashing.
Both the initial charge, and the initial boot, the screen is flashing white and black, and then there are the blank screen.
Through the USB cable to connect the computer, the computer can not find H2O DEVICE DISK.
So i can not use manual methods to restore factory Settings.
But
“- Turn it on and quickly tap both bottom corners of the screen at the same time. Tap a few times until something happens.”
the screen twice white and black,then the power light is flashing.
If anyone I encountered this kind of problem for KOBO aura H2O?
I must return to factory maintenance device?


thanks
