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

Advanced features include Active When placed in an HDMI slot on a television set or computer monitor, the device turns that display into a personal computer

--slot SLOT Use SLOT; 'all' for both slots, 'other' for non-current slot --set-active Sets the active slot before

fastboot_ error_ failed to identify current 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

fastboot change 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
