Excuse my ignorance, but how do I flash with EDL mode? As mentioned, I am using Ubuntu.

@rocket2nfinity MSMDownload is a windows program, no? Or is there a Ubuntu version of it?

Hi. I am using a Ubuntu computer to try to install Ubuntu Touch to a new Oneplus N10. I have unlocked the OEM, and unlocked the device, as seen from the response below. But I cannot unlock the Critical partitions. If the bootloader is locked, the result is below:

fastboot oem device-info
(bootloader) Verity mode: true
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true

When I try to unlock critical partitions and bootloader us unlocked, I get:

fastboot flashing unlock_critical
FAILED (remote: ' Device already : unlocked!')

Any ideas? What am I missing?

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?
