I have a Poco F1 with the latest LineageOS rom found elsewhere on XDA. I had to do a factory reset because of some weird problem, assuming that my backup to Google Drive could be restored during the setup wizard.
The backup turns out to be encrypted with my lock screen pattern, a policy . Unfortunately, I was using a 6x6 unlock pattern, but the setup wizard only allows me to enter a 3x3 pattern. Unlike other pattern screens, there is no 3x3/4x4/5x5/6x6 selector on the bottom of the screen. In other words: I cannot unlock mt backup.
Things I tried:
- Skip the restore process in the setup wizard, go to the system settings first to configure the exact same 6x6 lock pattern, and then return to the restore process. This did not help.
- Running adb shell bmgr restore also failed:
(I know, it says "done", but nothing changed and this happened much faster than I would expect a restore process to be.)
What can try next? All help is appreciated.
