# Example usage (as an alias)
# Assumes the device is running Android, syncs kernel modules (and whatever else)
# and then reboots and flashes the kernel
# $ alias aflashboot="adb remount && adb sync; aflash.sh -t -b"

# Flashes everything, from bootloader

Yeah, you can get it going in postmarketOS by using my pmaports branch here: https://gitlab.com/sdm845-mainline/pmaports/-/tree/mm-tracking

You'll need to get rid of the top commit it was just for my testing and doesn't work. 
Checkout HEAD~1 ("modemmanager: QRTR testing") and then change the modem manager APKBUILD to use this branch: https://gitlab.freedesktop.org/aleksm/ModemManager/-/tree/aleksander/qmap-settings-udev (from !501). Then:

pmbootstrap checksum modemmanager
pmbootstrap build libqrtr-glib --arch aarch64
pmbootstrap build libqmi -- arch aarch64
pmbootstrap build modemmanager -- arch aarch64
