As soon as I received my dual boot tablet 2 years ago [Hi12 Q64G4517 040 3840], I had trouble shutting down while on Android (there is no software shutdown to my knowledge). Over time, it has become more and more random so that I am often forced to do a hard reboot by keeping the button pressed for a long time. This restarts Windows by default (I cannot use a connected mouse in my use of it) and I then have to restart Android from Windows by software.
Basically, I’m afraid it’s a hardware problem (bad button contact), but I’d still like to try to reinstall everything (Windows and Android) because it’s become very unstable and painful to use.
On this forum I found this: https://forum.chuwi.com/t/topic/928
I downloaded the Android and Windows files but the link on the Windows and Android tutorials is dead.
How to find the right tutorials for the use of downloaded files?
Incidentally: is it possible to have a hardware problem repaired out of warranty in Europe and how to proceed?
