Method 2 (using fastboot):

fastboot getvar current-slot
  • if return with value ‘a or b’ meaning device support dual slot
  • let’s write patched boot image to both slot
fastboot flash boot_ab boot.img
  • if you have not write vbmeta earlier then write it like this
fastboot set_active a
fastboot flash vbmeta_b vbmeta.img
fastboot set_active a

then set active A & reboot

fastboot set_active a
fastboot reboot

fixing any bootloop issue: just set alternative slot, if a is active we set b or if b is active we set a

fastboot set_active a
fastboot set_active b

Single Slot device:

  • in earlier steps we check for a slot, if the return value is not A or B meaning device does not support slot, let’s flash boot image to boot partition.
fastboot flash boot boot.img

then reboot

fastboot reboot
