Fix bootloop caused by a magisk module
There are two methods to save yourself from a bootloop CAUSED BY A MAGISK MODULE:
Booting into safe mode
- Hold power button so the phone reboots
- When you see the boot animation, hold the volume down button AND KEEP HOLDING till you feel a vibration. If you don't feel a vibration, wait and see if it boots. If it doesn't boot, start from step 1 again, but this time try holding both volume keys
Then, reboot to get out of safe mode when the phone boots, and you should be able to boot. Note: all of your modules WILL be disabled

And that's it. Next time you face a bootloop, your phone should reboot automatically. Could take some time but it will. When a bootloop is detected, the module will disable all modules and reboot. Note: you have to reflash the module EVERY TIME you change the kernel
