So I decided to let my Kindle discharge (because I thought doing that once in a while is a good idea), but when it started to shut off instead of shutting off it kinda started to change to a black screen, but halfway stopped so now it is stuck on the last page I read mixed with this "fading to black" that started:
I tried debricking with kubrick, but that doesn't work because the screen doesn't change so I can't make the necessary manual input, but it seems that I still can enter usb download mode? At least kubrick recognized my device as having entered the usb download mode.
Any idea what to do? Charging doesn't help, hard reset doesn't work. My device was jailbroken when this happened.
