        Believe I read that the Oneplus installation for the 6T is recommended to be
        with a device that is running Oxygen 9??? Please correct me if I am wrong.

        Also, anyone successful in deleting Oxygen 10 and installing the 9 revision on the 6T to accommodate the installing of Touch??

            @portu51 The question from @rbhawk, me, and others is: How to install OxygenOS 9? I sent one device to OnePlus and they refused to downgrade ("not possible", haha).

            VollaPhone22 (dual-boot of VollaOS and UT 20.04 OTA-9), Pocophone F1 (pmOS, edge), FLX1 (Debian)

              @rbhawk I managed to install then stock Android/Oxygen 9.0.8 with MSM Download in EDL mode (lowest hardware recovery mode) with this tutorial : https://www.thecustomdroid.com/oneplus-6-6t-unbrick-guide/

              To start the 6 or 6T in EDL mode, set off the device and plug the USB while pressing volume + and -

              The only caveat is... MSM Download runs on Windows.

                You can use the roll back zip from here : https://forum.xda-developers.com/t/guide-rollback-downgrade-from-oos-android-10-q-to-stable-9-pie.4000645/

                you can flash the file from the oxygen update app or twrp. if you flash oos 9 from twrp on both slots twrp will not work ,you will need a twrp compatible with android 9 bootloader

                  @rbhawk It is impossible to install Ubuntu Touch on OxygenOS 10 base, because we are using OxygenOS 9 based kernel. You can just flash OxygenOS 9 to both slots and then, flash Ubuntu Touch.
