K5 Kindle Touch 10th gen bricked

Hi there,

all of the sudden my kindle is stuck at the "Guy under the tree" screen.

Long-pressing the power button achieves nothing, the screen flashes and goes back to the same image.

It was jailbroken and running 5.15.1 FW (updated after the jailbreak).

Suggestions? Anybody knows if Kubrick could be of any help?


Thanks!
