Hello, back a few days ago, I had to clean out my office space as our office will change vocation in the coming months. I found out my old Kobo mini. When I tried to start it, it was flashing green so I reset it and it worked, got back to home screen. However, when I tried to put the back panel, it froze (see capture) and e-ink is kind washed out at left. Do you know how I could revive it once again? Reseting it doesn't seems to do the trick anymore, maybe I broke something while putting the backcover? Any ideas? Thanks!
