Dear Forum,
yesterday something very strange happened: I successfully installed the 2025110800 update via ota, first reboot went fine.
Then, some hours later, while watching an unsuspicious news-website (guardian.co.uk), out of nothing, the device shut down. Any attempt to reboot leads to the google screen, then a few seconds with graphene logo, finally switching to "grapheneOS Recovery", displaying an error saying: "Cannot load Android system. Your data may be corrupt." If I repeat the process, same result.
First thought was to sideload the update via adb again, since fastboot mode seems still reachable via pressing volume down while rebooting. ("Fastboot devices"-command showing correct device number). However, the device does not accept the "fastboot sideload ..." command. (Bootloader is unlocked, however)
The error screen offers an additional device reset, which I would like to avoid.
Maybe the collective wisdom has an idea how to proceed?
thanks in advance for any suggestion:
