How to enter flash mode
Hold down the home button + the power button + the volume down button from a power off state to get into Odin mode.
NOTE: Flashing with heimdall gets stuck, so i had to use adb sideloading to get postmarketos flashed.
NOTE: msm-fb-refresher, which despite its name is not exclusive to msm SoCs, is required if you didn't choose weston as your ui, so to add it do
pmbootstrap init and press enter until you get to additional packages, add msm-fb-refresher there.
Follow the installation guide, but install with:
pmbootstrap install --android-recovery-zip
and flash with:
pmbootstrap flasher --method=adb sideload
while in adb sideload mode.
