        Hi, I did some experimenting and now I cannot install UT on my 6t. All installation guides(that I tried) presume that you have >android 9 installed on the device.

          @CyBerT The easiest way would be to use the MsmDownloadtool and reinstall OS9 as described in the OP6/T section of this forum.

          You could also flash it by using fastboot since your installation is not corrupted.

              @CyBerT Plenty. Here's one

              https://www.getdroidtips.com/oneplus-6t-stock-firmware-collections/

              Here's another

              https://xdaforums.com/t/rom-stock-fastboot-op6t-stock-fastboot-roms-for-oneplus-6t.3862516/

              If you still have UT Recovery flashed to your device, you can use that. Personally, I just use msmDownloadtool. Going back and forth between UT, Mobian, PostmarketOS messes with your partitioning. It is often best to just use the factory tool to reset it - especially if you haven't flashed a ROM before.

                    @CyBerT Did you download the zip file recommended in the ubports device page? Sounds like you just downloaded msmDownloadtool by itself and not the OS image that should go with it

                      You can download the fastbootrom from (oneplus6) fastbootroms/files/OnePlus%206/9.0.9-OnePlus6Oxygen_22_OTA_034_all_1909112343_dd26-FASTBOOT.zip
                      (use this ZIP, because you need Android 9 for UT)
                      after extract this file exract the image.zip you get some img-files this files must flashed with fastboot - for example:
                      Step 1
                      fastboot -w

                      Step2
                      fastboot flash xxxxxx_a xxxxxx.img &&
                      fastboot flash xxxxxx_b xxxxxx.img
                      ....
                      next
                      ... with every file in the image-folder, but some file can not flashed but this is dosn't matter

                      If you are ready with flash start form bootloader, give the device some time and the onplus6 Start into stockrom. You can in setting>developer-mode adb-usb activate and reboot into bootloader (fastboot)! Next step you can use the upborts-installer

                      fastbootrom for 6t

                      If you need a list of terminal commands I can post if you want?

                          @CyBerT I am not shure if the msmdownloadtool works with Ubuntu (maybe with wine or Windows in vm) - I don't use Windows.
                          I have used the methode via fastbootrom, because you can track every step and understand what is causing the error.

                          If you want the list of terminal commands, let me know. All you have to do is copy and paste.

                            It seems like I cannot get in to "Recovery mode" of the phone(actually both 6 and 6t). When I choose recovery mode it just reboots the device.
                            Does somebody know what the problem might be or can I fastboot flash UT to the device?

                                Step 3
                                Start Smartphone from bootloader

                                The oneplus start in Android 9 Stockrom!
                                Finish - you can install a recovery or other ...

                                  @Dieter42 Ok first I would like to try something else then I will come back to fastboot.

                                  But first after installing Android 9 I try to install UT with installer and when it finishes I get stuck at boot screen.

                                    And I get stuck at boot screen because newer version of UT does not work with OP 6, and that is why I flashed mobian in the first place!!!

                                      @Dieter42 Ok back to this particular fastboot issue; could I leave the bootloader as it is and flash UT on a and Mobian on b? Would I be able to boot both? List of commands would be much appreciated.
