          @wusa When you unlocked the device did you boot back into Android and set it up again?

          Xiaomi Redmi Note 7.... And more...
          I have too many devices...

            If you mean the installer, yes i tried both versions.
            First install and wipe data and
            First install without wipe data.
            Both runs into the same error.

            No, first i installed OOS and set everything up.
            Than i tried to flash UT. In Fastboot the message tells me the device is unlocked.
            I unlocked the device years ago.

              @wusa I found that devices would lose connection if I did not boot back into Android directly after unlocking and went straight into the UT install (trial and error).

              I had an issue on a Oneplu3 where it would not load any ROM. I ended up re downloading the last ROM and installing it piece by piece in fastboot. This worked and then allowed UT to be installed.

                I dont know which ROM was my last ROM i tried so many different custom ROMs my whole time i used the phone.
                But i also tried to install TWRP through fastboot and i installed OOS again through the console in ubuntu.
                Then i did the developer settings and connected my device.
                Than i tried the installer again. Everything failed.

                I dont know how to proceed now.

                Maybe someone can tell me an order how to proceed step by step again.
                What I should delete, how and where I should delete, etc.

                  @wusa Not just that. You might have to install TWRP and wipe and format cache, data and system to ext4.
