Yesterday my 7-year-old daughter was fiddling with the flipper, pushing buttons around. After that, I found the flipper’s screen off. It was not responding to normal buttons.
I thought she exhausted the battery. I plugged in the charger, but the charge light never turned on.
I managed to reboot with LEFT+BACK.
The flipper booted up and showed the usual screen. However, when I pressed CENTER, it was starting the snake game. I figured out that I needed to switch into “Brainiac” mode by pressing RIGHT and selecting this mode.
Then I found out that my all saved RFID keys were deleted. I find it unlikely that my daughter was deleting the keys one by one. As I do regular syncing with the phone app, I had the backup of all keys and restored them successfully.
HOWEVER, when I decided to update to the latest firmware
0.82.3 using the phone app, I noticed a strange behavior.
The update has been pushed from the phone to the flipper. Then the screen turned off. When I rebooted with LEFT+BACK, the screen turned back on, it showed the update messages and the progress bar. After a few update messages, the progress bar filled up, and the screen turned off again. I had to press LEFT+BACK again, and it booted up finally.
To double check, I ran the Flipper OS reboot. The screen turned off and didn’t turn back on. Again, LEFT+BACK helped boot back into the OS, and all was functional again.
- what may be the technical cause of such a behavior, when a reboot only works via LEFT+BACK?
- how do I fix this to make flipper boot normally again?
