        @keneda Okay in Fastboot mode there can the device be detected. If i switch into the recovery mode it is unable to detect the device. How can this happen?

        With fast boot there is the following output:

        (bootloader) Verity mode: true
        (bootloader) Device unlocked: true
        (bootloader) Device critical unlocked: false
        (bootloader) Charger screen enabled: true
        (bootloader) enable_dm_verity: true
        (bootloader) have_console: false
        (bootloader) selinux_type: SELINUX_TYPE_INVALID
        (bootloader) boot_mode: NORMAL_MODE
        (bootloader) kmemleak_detect: false
        (bootloader) force_training: 0
        (bootloader) mount_tempfs: 0
        (bootloader) op_abl_version: 0x0
        (bootloader) cal_rebootcount: 0x31
        OKAY [  0.001s]
        Finished. Total time: 0.002s

          Well, i had a similar detection issue whith my MX4, but that was the opposite, phone was detected in normal boot and recovery by adb command, but not in fastboot mode...
          But that didn't prevent from installing, my problem was a driver issue (my device needed 3 drivers installations, one for each device mode : normal, recovery, and fastboot).

          If you want to check my adventure installing UT UBP version on my phone, you can go there.

          Edit :
          I see

          (bootloader) Device critical unlocked: false
          

          In your log, maybe it's the issue, and that should be on "true", but i can't tell, not knowing your device much.

            @shadowcastiel @Keneda is right double check the bootloader is actually unlocked thentry the commands again. Both need to detect your device.

              @keneda nah critical unlock is for updating the bootloader I guess. So my problem is now. The device won't be detected if I connect it within the recovery mode. With the fastboot is everything fine. So my problem for now is, I don't know why no Notebook (Windows, Mac oder Linux) can detect the phone while it is in recovery mode. And no it also won't be shown in the device manager in windows.

                @shadowcastiel So you are sure the bootloader is unlocked (fastboot oem unlock) if so you could try here https://t.me/WelcomePlus our install group. I have no experiance of OP6 but it is normally something simple and someone there will know. If you enabled oem unlocking, developer options and Advanced boot (not sure if this is needed) not sure where to go.

                  @lakotaubp Well i ran the command:

                  fastboot flashing unlock
                  
                  FAILED (remote: '	Device already : unlocked!')
                  fastboot: error: Command failed
                  

                  So why the fastboot is still telling me this?

                  fastboot oem device-info
                  (bootloader) Verity mode: true
                  (bootloader) Device unlocked: true
                  (bootloader) Device critical unlocked: false
                  (bootloader) Charger screen enabled: true
                  (bootloader) enable_dm_verity: true
                  (bootloader) have_console: false
                  (bootloader) selinux_type: SELINUX_TYPE_INVALID
                  (bootloader) boot_mode: NORMAL_MODE
                  (bootloader) kmemleak_detect: false
                  (bootloader) force_training: 0
                  (bootloader) mount_tempfs: 0
                  (bootloader) op_abl_version: 0x0
                  (bootloader) cal_rebootcount: 0x31
                  OKAY [  0.001s]
                  Finished. Total time: 0.001s

                    @shadowcastiel Try:

                    fastboot oem unlock
                    

                    and:

                    fastboot oem unlock_critical

                      @mrt10001 for both commands the following output:

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

                        @shadowcastiel Great so that means the device is definitely unlocked.

                        Flash the device back to the required stock ROM and go into developer options and ensure that the check for OEM unlock is in the unlock position (it may be giving you a false flag).

                        When you have done that, install TWRP and ensure all the partitions are on EXT4.

                          @mrt10001 how can I flash it back to stock rom? I am not able to find a device:

                          adb reboot bootloader
                          error: no devices/emulators found
                          

                          Is my phone now bricked? What happened here? How can I install TWRP now? I am really not sure for now.

                            @shadowcastiel make sure the phone is disconnected from the USB cable and switch the phone off. Wait a few seconds to make sure. Then press the power button till and volume down buttons together until the phone switches on. This will boot you into fastboot mode. Connect the phone to the PC and install TWRP using the fastboot command:

                            fastboot flash recovery <location and name of your TWRP img file>
                            

                            Once TWRP is installed, your phone should be picked up by the PC and you can copy the stock ROM image over to the root of your device and side load it with TWRP.

                            Download the stock image from here

                            I used rollback image.

                            Once the image is installed, reboot the device and set Android up. Make sure it is on Android 9 and enable developer options. Make sure OEM unlock is enabled or has been enabled.

                            Then reboot the phone to the bootloader, install TWRP and ensure the data and storage partitions are EXT4 - this is important as UT won't install.

                            Try UT install again. If it fails, go back to TWRP (you will have to install it again) and wipe the data partition and ensure the data and system partitions are EXT 4, then wipe all the partitions except OTG. If you get warnings when these processes are happening, when they end reboot to fastboot, install TWRP and do it again.

                            If no warnings try the UT install again.

                            I apologise, I have skimmed over a bit.

                              @mrt10001 Just out of interest could you not just install TWRP then wipe and format EXT4 system,data and cache as needed like with the OP5 then run the installer.

                              Edit: If on Android 9 that is.

                                @lakotaubp If it was on Android 9, but I would go back to stock to a)make sure it is on Android 9 and b) to ensure the OEM unlock button has been checked.

                                It is a faff, but I have found with all the devices, if an error get thrown up, back tracking and going back to stock is the best way to success.

                                  @mrt10001 Good point best to check that everything is as it should be to avoid false errors and know the process is correct.

                                    @lakotaubp is now all fine with the OnePlus 6. I recovered it with the Qualcomm Emergency Downloader.
