I have a Ubuntu system with UBports on it. I was able to unlock the new Oneplus N10 (Android 11) without problems, and was installing when it came up with the error that 'flashing is not allowed for critical partitions'. When I tried 'fastboot flashing unlock_critical' I recieved the notification that the phone was unlocked. adb and fastboot both installed, but UBTools will not work in fastbootD.

I may be able to install an *.img file for billie, but I cannot access one. Can anyone assist?
