How to enter flash mode
- Your bootloader must be unlocked via this method: https://forum.xda-developers.com/t/unlock-root-twrp-unbrick-fire-hd-8-2018-karnak-amonet-3.3963496/
- 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 and 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
