Can anyone help me with how to change the boot screen and shutdown screen on my Lenovo Tab M10 FHD Plus? It seems to me that I cannot change the files in the system. It won't let me edit them or replace them etc.
I've tried for hours with this and got nowhere. I tried changing files in system files but they're locked up and can't be edited or overwritten, etc. I tried an app that's meant to write over them for you with new animation files for start-up and shutdown, but that won't do the trick either.
Any help would be much appreciated.
