Big problem with a Kindle Oasis 9th generation, with standard Amazon's firmware. The device is already out of warranty by a very long time, but it was working fine so far. It stopped working suddenly; after changing the language in the settings the device started rebooting and never was back again. It is stuck on the boy under the tree screen, with the screen illuminated, with no progress bar. The device is not recognized as a USB device, so it freezes before that is possible.
I searched in the Internet for help and tried many things, including the hard reset (the screen goes blank but then back to the same screen), trying to drain its battery (not easy because at some point it seems that the light gets off and so probably uses very little energy), recharging during a long time with a wall charger (using the original cable and charger), etc., with no solution found.
The closest point I was to solve the problem was this: after I got a "Low battery message" I left it charging overnight and next day I had a "Critical error troubleshooting" screen (similar to the one shown in
https://www.reddit.com/r/kindle/comm...le_is_over_it/). I tried the option of resetting to factory settings, but it didn't work (I'm again stuck with the boy under the tree screen, with no error shown in the middle).
Now I'm trying hard to get again the "Critical error troubleshooting" screen (no luck for the moment), in order to see if with that screen the device can be recognized as a USB device. I read at
https://www.mobileread.com/forums/sh...d.php?t=280483 that there is REBOOT_LIMIT that may force that screen to appear, but I really tried rebooting many times.
Any advice or idea is welcome!
