Thank you for your application ! It's the easiest way to disable Acer Shell !
Even if was forced to use Acer Tool to reboot with rw permission because in the Terminal Emulator it doesn't work when I want to remount system with rw : " Mount : operation not permitted" . Do you know why ? (My bootloader is unlocked)
And I have also a problem with my lockscreen : when I listen to music with any player, the background is black... Is it normal ?
Despite it, I can personalize my phone as I want
