        I already had downgraded and used UT 16 and wanted to try UT 20, but there were some issues
        then upgraded to android 11 and tried postmarketOS, but it feels like a beta
        so I want to try UT 20, but it is not working šŸ˜ž

        is UT 20 planed for OnePlus 6, or will it only support UT 16?

          @SSD It does work fine on the OPO6T and 6. The Qualcomm crash dump appears after some reboots, esp when the battery is low. A power off from the power button and power back on gets it back up.

            Going back from postmarked OS did not work for me either. On my other onpluse 6 my UT 20.04. STABLE works fine. But also postmarketOS gets better and better with plasma mobile, so just keep it and get another oneplus 6. Just an idea...

              @MrT10001 I just tried multiple reboot and every one crashed
              also @Pingu I was using v22 postmarketOS, but edge should be better, so it doesn't feel like beta

                @SSD Could be the sign of a dying battery.

                    @SSD On my OPO6 and 6T, on the good ones, I get about two days on Xenial. On Focal it is hit and miss with a day. I can get about a week on Aeroplane Mode (which kind of defeats the purpose of the device). Oddly though the OPO6 and 6T are the only ones that give me a Qualcomm crash and that is when the battery is low or has died and I am plugging it in for a recharge.
                    For me it is a good device, but not quite ready in the sense for daily usage. That is like a lot of devices running UT, many factors involved.

                      @SSD as I wrote, if you flash postmarkedOS with installer, you can not go back to UT. No Xenial and no Focal. It is one way. I tried many things, twrp etc... Thats why I keep it with PMOS, watching, enjoying it. Maybe someone knows a way back?

                      My other oneplus 6 works fine with Focal.

                        I guess you have to reinstall the good android version before installing UT back, like for any phone there.

                        For doing that, you need to use android flashing tools, or, better, and if exist, oneplus flashing tool.

                          Via fastboot flash an appropiate recovery and dtbo image.

                          I would use a TWRP recovery image, and a dtbo image from LineageOS.

                          fastboot flash recovery twrp.img

                          fastboot flash dtbo dtbo.img

                          Without flashing the dtbo, you won't be able to boot to recovery.

                            In worst case scenario, MSMdownloadTool will get you back to stock OOS
