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 pmbootstrap flasher --method=adb sideload
 * 1) Make sure you're booted into TWRP at this point
