How to install to A/B slot devices?



  • I understand how this layout works, but I'm having trouble.
    Say my current slot is A. Is the right thing to do to

    • have twrp flashed on boot_a
    • flash halium to boot_b
    • enter recovery on A
    • run twrp-installer.zip
    • enter recovery on B
    • run install script

    unfortunately, either the twrp installer is bad/not working because I can access twrp shell from adb, but don't have touch functionality and it will not boot into twrp on the halium-boot slot, so I'm assuming that the UB installer script won't do anything.

    I'm on the essential ph-1
