        Once your bootloader is unlocked you must reboot the device and set Android up again.

        In Developer mode you must enable USB Debugging for the installer to see the device.

        I had done that.

        My first problem was that the "Allow USB debugging?" prompt was not appearing on the device after plugging it in. After several more attempts, it appeared and the Ubuntu Touch installer was able to recognize the device. (I think it may have been due to the device not having the correct date and time set, but am not sure).

        After setting "Installation options":
        Channel: 20.04/arm64/android9plus/stable
        Wipe Userdata: ✔Wipe personal data (required for new installs)
        Bootstrap: ✔ Flash system partitions using fastboot

        The device rebooted to the Fastboot menu, and the Ubuntu Touch installer displayed:

        Cleaning up...
        Formatting system partition

        Nothing happened for about 20 minutes, until I gave up.

          This is what te installer should look like on first install.

          As you can see that is not displayed, so you must be using an older installer.

            I have 0.9.7-beta from latest/stable channel installed. Which version should I be using?

              @ginggs It should still work, however as we know, it also may not 😠

              On my Ubuntu Machine I have installed it using the snap store and the Edge version which is version 0.10.0. I use this version on my Windows machine as well.

                Thanks! OK, I did:

                $ snap refresh ubports-installer --edge
                ubports-installer (edge) 0.10.0 from UBports refreshed
                

                Unfortunately, the result was much the same.

                The device rebooted to the Fastboot menu, and the Ubuntu Touch installer displayed "Cleaning up..." but nothing further happened.

                I'm wondering whether I need to go back a step, and figure out why the Local Upgrade of OnePlus6Oxygen_22_OTA_054_all_1908302047_fulldowngrade_f019784c78234a67.zip does not work.

                  @ginggs That rollback has worked for me (the OB25 rollback is for the OP6, not 6T).

                  Download the last Android 9 flashable zip from here.

                  On a Windows machine, open a terminal in the extracted folder and attach the device in fastboot mode. Then run the flash-all.bat file.

                  This will return the device to Android 9.0.17.

                  Then you can try again with the UT installer.

                  Something must have gone wrong on the install. I have found the OP5/5T, OP6 and 6T the devices that give me least problems downgrading Android and installing UT.

                    Thats for the OP6, not 6T. Slightly different ROM even though there is cross platform development.

                    Go back to Android 9 for the OP6T and start again (I always go back to the start when there is an install issue).

                        I didn't find a Windows machine, so tried to flash from Ubuntu.

                        I looked at flash-all.bat, and saw that basically all it does is:
                        fastboot -w update images.zip

                        So I unpacked 9.0.17-OnePlus6TOxygen_34_OTA_024_all_1909112343_d5b1905-FASTBOOT.zip on my Ubuntu machine and after booting the device into Fastboot mode, ran:

                        $ fastboot -w update images.zip 
                        

                        Which seemed to be working, but then failed at:

                        ...

                        I tried again, this time without -w:

                        $ fastboot update images.zip
                        

                        This completed without error, however attempting to boot the device now gives me:

                        QUALCOMM CrashDump Mode

                        Attempting to enter Recovery mode results in the same error, but I can still enter Fastboot mode, so the device is not bricked yet. :grinning_face_with_sweat:

                          @ginggs You cannot flash that through fastboot like that. With a .bat file it has to be Windows and run through the Windows terminal.

                          Linux would use the .sh and run through a CLI.

                          To manually flash you need to extract the images.zip file and then flash manually in this order:

                          fastboot flash aop_a aop.img
                          fastboot flash aop_b aop.img
                          fastboot flash bluetooth_a bluetooth.img
                          fastboot flash bluetooth_b bluetooth.img
                          fastboot flash boot_a boot.img
                          fastboot flash boot_b boot.img

                          fastboot flash dtbo_a dtbo.img
                          fastboot flash dtbo_b dtbo.img
