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 :( :(
