Hi there,
My daughter asked me to change the sleep screen on her Kobo Aura H2O (2015). I followed some instructions to change the sleep screen to book cover and it worked. But when I tried to have a picture folder I copied a wrong KoboRoot.tgz file in the reader. Since I restarted it the screen is white.
Now the screen stays white, and the led is blinking white. I tried to follow the instructions to put it back to factory setting, it didn't work. Nothing I tried worked.
I can turn it "off" it I push the start button 15 sec, and turn it "on" after: I will see the screen blink black and then go back to white.
My computer can't find it.
The battery was full when it happened.
Is there something I can do to fix it?

Thank you for your help!
