        I installed UT using the installer, selected the 20.04 rc channel, but now I want to switch to a different version. I have enabled developer mode.
        Using

        adb reboot bootloader

        results in the screen turning off, but nothing else happens. The terminal is stuck on that command until I ctrl+c.
        Trying to enter fastboot using volume up+power is stuck in a loop of splash screen to "bootloader unlocked" message then back to splash screen for as long as I hold the buttons. When I release them it just boots normally. Holding volume up+volume down+power results in splash screen flashing for a moment and then disappearing and then flashing again for as long as I hold the buttons. Again releasing them results in UT booting normally.
        When I try to use the installer and select FP4 manually it also gets stuck on rebooting to bootloader.

          @bubba_pl If you go to Updates in System Settings and can you not see the other update channels available. If you can try that.
          If using the installer try ticking all the wipe and bootstrape options ( if you have not tried that) and install the 16.04 Devel or RC. We also have this group https://t.me/ut_on_fp4 for more help.

            @Lakotaubp Thanks for the quick reply, I found help on the telegram group.

            To enter fastboot I had to

            sudo reboot -f bootloader

            in the UT terminal
