flashing:
 update ZIP                 Flash all partitions from an update.zip package.
 flashall                   Flash all partitions from $ANDROID_PRODUCT_OUT.
                            On A/B devices, flashed slot is set as active.
                            Secondary images may be flashed to inactive slot.
 flash PARTITION [FILENAME] Flash given partition, using the image from
                            $ANDROID_PRODUCT_OUT if no filename is given.

basics:
 devices [-l]               List devices in bootloader (-l: with device paths).
 getvar NAME                Display given bootloader variable.
 reboot [bootloader]        Reboot device.

locking/unlocking:
 flashing lock|unlock       Lock/unlock partitions for flashing
 flashing lock_critical|unlock_critical
                            Lock/unlock 'critical' bootloader partitions.
 flashing get_unlock_ability
                            Check whether unlocking is allowed (1) or not(0).

advanced:
 erase PARTITION            Erase a flash partition.
 format[:FS_TYPE[:SIZE]] PARTITION
                            Format a flash partition.
 set_active SLOT            Set the active slot.
 oem [COMMAND...]           Execute OEM-specific command.
 gsi wipe|disable           Wipe or disable a GSI installation (fastbootd only).

 snapshot-update cancel     On devices that support snapshot-based updates, cancel
                            an in-progress update. This may make the device
                            unbootable until it is reflashed.
 snapshot-update merge      On devices that support snapshot-based updates, finish
                            an in-progress update if it is in the "merging"
