Can I change the Boot Slot from Fastboot with a command?

fastboot - platformsystemcore fastboot set active slot I choose yes and then get back in recovery with “Active slot: b ” I didn't need to do fastboot —set-active=b So I then relaunch: adb fastboot getvar currentslot Then change slot a to b or b to a if phone already slot a first set-active=a or b Bootloader

fastboot change slot set-active=a if you have slot B active or fastboot --set-active=b if you have slot A active Check the active slot with fastboot getvar all
