How to enter flash mode

  • PMOS needs to be flashed using TWRP instead of fastboot so the boot.img can be patched with the amonet exploit.
  • TWRP can be reached by holding vol down and power at boot.

Installation

pmbootstrap init
pmbootstrap install --android-recovery-zip --recovery-install-partition=data
# Make sure you're booted into TWRP at this point
pmbootstrap flasher --method=adb sideload
