    Questions:
    1. Does this method factory reset the phone twice?
    2. Can the second file from point 6 only be flashed without flashing the file from point 1 in your answer?

    Yes, it erases all data.
    No, you need to install the rollback build first

    Hi guys, I`ve rolled back before many times but yesterday I had the "wise" idea to try lineageOS cos it had android 11 but also, I got some bugs and wanted to go back to OOS 10. Any idea of the procedure? I`ve spent half day with a bricked phone to restore it to LineageOS again...so no clue for now how to rollback to oxygenOS frankly... no option for local update here...

    Thanks so much for instructions and file links. So disappointed with OnePlus after moving to OOS 11. Phone performance after upgrade was worse than my 5 year old Motorola. Never had to downgrade a device before so I was very anxious. Backed up all data to Google Cloud using OnePlus Switch. The only issues I experienced were...
    1. Restoring backup on beta build, it got stuck reinstalling apps. Showed "Installing 1 of 126" for several minutes. I was able to stop the update and reboot and it picked up where it was and completed update.
    2. Call log was not restored from OnePlus Switch backup. Although it says it backs up call history, the call history was empty. I had another call log backup from SMS Backup & Restore that was on my Google Drive and was created the previous day, so I lost one day of call history by restoring this one.
    One Plus 7 Pro appears to be back to original performance.

    You should have updated OnePlus switch app before restoring the data.
