- If everything worked your phone should now boot into OxygenOS. The files will be flashed to your currently active boot slot. If any of them fail to flash, switch to the other slot and start over from the beginning. I wasn’t able to flash ODM, product, system, system_ext, and vendor to slot a, and had to use slot b instead. To check the current slot:
fastboot reboot
To switch slots:
fastboot getvar current-slot
or
fastboot –set-active=a
fastboot –set-active=b
