7. 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 getvar current-slot

To switch slots:

fastboot --set-active=a

or

fastboot --set-active=b

  1. I tried to perform this downgrade on my new Nord n10 5g but the System Update setting for local upgrades is telling me to place the update file in the root of storage. So I had it there, but the system would not find it automatically and there was no option to browse and select. Should I be renaming the file to something else, that will be recognizable as a system update? Thanks for any help.
