so… i’m running lineageOS on my phone (a Oneplus 6T) , have been for a very long time. Usually i’m really happy with this but not tonight:
- Phone suggest a update of OS , just a weekly build. Sure why not, so it does it thing and i reboot, all good.
- Open a app to listen to some podcast: screen goes black flickers a couple of times showing empty launcher. thankfully power button long press shows shutdown menu (but looks different from normal?) and lets me restart
- do same thing again , ok looks like latest update broke something
- update app, same
- go to settings , updates to try to revert to previous version: no option to install older version , only option is export. weird ok lets try to export old version . Now it lets me install that
- installation loops , seems it failed
- try app again, same black screen , hold power button to get boot menu again : now phone says ERASING … wait what stop no … (does lineage have a panic wipe my phone key combo i didn’t know about?)
- rebooting , rebooting again
- welcome setup your phone screen :(
- remember that my cloud server disk burned last week , no way to restore backups :( :(
I think you should have used ADB to boot from the other A/B partition
