      Hi all,

      After some custom rom hopping i want to give it a try to UT. So I was using my redmi note 9S like two years with lineageOS. Other day i checked ubports installer try to install the UT.
      First rookie mistake i didn't downgrade to android 10 and tried to install and installer stuck at reboot to fastbootd and i forced it and device soft bricked. After failed attempt I restored device to stock rom but this time i installed MIUI v12.0.4QJWTRXM which is android 10. After this I installed the Ubuntu succesfully everything is working fine except make/receive calls. I know VoLTE is not supported. so i go back to first stock rom than lineageOS.
      So after going back both stock and custom I can't make/receive calls. IMEI is showing up correctly tried another SIM but no lock.( for both SIM slots). How can I fix this or is there way for this?

      Also as a bonus, i now have 3 second cuts on sound output.
      Sorry for the long post. Thanks in advance.

        Hello i am sorry for your problems and i hope they get resolved. Looks like you have curtana miatoll device. The android ROMS which we tested and are working properly on that device are the following:

        • 11.0.11.0.QJWMIXM
        • 12.0.1.0.QJWMIXM
        • 12.0.2.0.QJWMIXM
        • 12.0.3.0.QJWMIXM

        I would advice to try one of them and see if your problem get fixed.

        If i remember correctly the most stable one was - 12.0.3.0.QJWMIXM so please try this one

        Best of luck!

            Update. If anyone encounter with the problem i had which is can't make/receive a call after going back to android from Ubuntu on Redmi Note 9S. Try "V11.0.10.0.QJWMIXM Global image" this image fixed calling issue for android.

            I'm gonna install "V12.0.3.0.QJWMIXM Global Image" and try Ubuntu again as @beyolf suggested above.

                The issue is fixed. I installed "V12.0.3.0.QJWMIXM" image to the phone, then installed UT with UBports installer. Now I can make/receive calls. Thanks to @beyolf.

                    That is very but very strange that you can call with version 12.0.3.0. May I ask which region of the country you are from? I have also tried to install Ubuntu Touch several times. Also tested many versions. Some worked and others did not. I made it up to version 12.0.5.0. Of course I also have versions of Android that run to use UT or other systems. Otherwise, good luck to UT. If you are missing apps, you can create your own with Webber. Of course they are not real apps but they are very helpful.

                      @DPITTI it is not strange at all, his version of miatoll is curtana, your version is joyeuse. 12.0.3 has problem on joyeuse NOT on curtana.

                      The different miatoll devices versions work best with different android ROMs and the Android ROMs are device specific, because there are differences in the vendor blobs between the different miatoll device versions.

                        Okay, I wasn't aware of that. I'm just not a developer 🙂

                          no problem , that's why I am explaining it.

                          Also because of the reason above I asked you which one is your device, when you reported having problems, so I would know which android ROM to recommend you. For joyeuse the know working well ROMs are:

                          12.0.2 and 11.0.3. this are the ones which most of the joyeuse users reported that are working stable with UT focal.

                          P.S. Just an advice when you are unsure of how something works better ask for clarification instead of jumping to conclusions.

                          Have a great day 🙂

                            Hi thanks for this good advice, I know that Ubuntu Touch will be good. I'll keep an eye on the news channel, it's definitely better. On the subject of Bluetooth and FM radio, I will probably have to accept restrictions. Even with alternative Android roms there are problems. If I want to go back to UT I would have to downgrade to 10 again 🙂
