It is running the latest firmware (I updated 2-3 days ago).
As the title suggests I am stuck in the sleep mode.
When I was finished reading yesterday I simply put the device in sleep mode. The next day pressing the power button did nothing. There is also no response to the long press on the power button.
Pushing the reset button on the bottom makes the notification light blink a few times but the screen still shows only the sleep mode state. Factory reset (holding the light and power button) make the light blink a bit faster but no change on screen.
The device obviously doesn't get recognised when plugged in a pc.
Also, warranty ran out a few months ago.
I've already had trouble with this device before such as the device freezing every 6 pages, some clicks didn't register, etc. I did a factory reset and it didn't solve any of those but I could still keep using it. There is no hardware damage as far as I'm aware.
Any advice would be welcome. Willing to provide any other necessary information.
TLDR: Stuck with the sleep mode screen, preforming factory reset with the buttons does nothing other than make the notification light blink. Also had trouble with the device in the past.
