I was playing with my new Kobo Glo and I thought I bricked my device.
I read one post of Mrs_Often and the hint didn't work but gave me one idea:
Users of Kobo Glo, to hard reset your device do these steps:
1 - Hold the light button.
2 - Press and release the reset button.
That's it, the device will be good as new
Thanks Mrs_Often for your post!
