@MrT10001 That seemed to be the issue, thanks! Not sure why the installer interpreted the phone as a different device, but all was OK once I unlocked again. Additionally, for anyone else who might stumble upon this, I had a random Android emulator listed in ADB, which caused the installer to get confused and raise an error. This turned out to be a Native Instruments background service, for some reason. Following https://stackoverflow.com/a/33810103, I was able to remove it and continue the installation.

Now I could unlock the bootloader. Windows 11 Pro didn't work. But Linux Mint 21.3 Cinnamon works: Open Terminal. adb devices adb reboot bootloader fastboot oem unlock (works) ubport installer worked. Thank you for your help!

@lukasfixit Did you have the correct version of Android installed before you started the installation?

@frifo Congratulationss! Satisfying to hear that it finally worked. Enjoy Ubuntu Touch!

SUCCESS! Hard to find out what's been the essential step. I just booted OxygenOs 10.5.7 this time with a SIM-card inserted and connected to WiFi immediately. Surprisingly now I could enable OEM-unlocking and after that "fastboot oem unlocked" without any issues. UT 20.04 is running, so the device will be my daily companion from now on. Thank you so much, mates! Didn't find out to mark that thread as solved.

@Ida_ Thank you for pointing me to the thread regarding VoLTE success stories. Unfortunately, my carrier is AT&T, which apparently is stricter in what it allows than some other carriers. For example, the only U.S. success I see in that thread is using a Xiaomi phone, which is not in AT&T's compatible phones list. I appreciate your further search suggestion too. Maybe that will lead me to an appreciable solution in the future, though for now I assume the Ubuntu Touch "Supported Devices" list includes all that are really prepared up to the stable standard I need.

@MrT10001 Thanks for the input. That makes sense, especially now that Apple is playing along with RCS. I imagine the proportion of messages sent by SMS/MMS protocols is dropping dramatically. Perhaps I'll try a different carrier.

@MrT10001 Yeah those features would be nice. But first things first get my new device a sim card to test really mobile out in the wild. By far best thing until now is battery lifetime. I really kept playing around all day long and it lasted for nearly 2 days. Great work!!

@rubencarneiro Thanks for the tip! I had meanwhile procured a global version and have been daily driving it for a few weeks. Works great! Thanks sincerely for all your work. I'll probably still convert the TMobile one.. even if I sell it, good to have more phones out there running UT.

@jam1388 Thank you for that....but the phone number they give is not good for NZ. Would somebody mind calling them for me and getting the token that will release my metro Nord N10 5g. I can give you the serial number by email.

@Pingu Thanks, Enjoy your Ubuntu Touch device.

@kristatos said in Cell-Broadcast: @dosolly On my Volla it isn't activated after cold boot and I can't activate it through system-settings. So I've created a systemd-timer and a corresponding systemd-service that enables CB via ofona-scripts. Timer: [Unit] Description=Aktivieren von Cell-Broadcast [Timer] OnBootSec=2min Unit=enable-cbs.service [Install] WantedBy=multi-user.target Service: [Unit] Description=Aktivieren von Cell-Broadcast [Service] Type=simple ExecStart=/usr/share/ofono/scripts/enable-cbs [Install] WantedBy=multi-user.target After that you have to enable timer and service and CBS is enabled 2 minutes after a cold boot. The CB-test yesterday showed me, that it's working (before, there was no way to check it ) Thanks a lot, will try it later.

Hi @Jam, as @MrT10001 and @rubencarneiro already informed. Yes Android downgrade to 10. This website was helpful for me, but you should check the Windows drivers first or simply install them in advance. Windows would then complain if these are already installed. See therefore first: My device isn't detected Go to device manager and make sure your phone shows up as QDLOADER 9008. If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file. In the link described above! Now I wish you good luck and perseverance with the installation. Greetings Mario

@tq sudo apt update is not recommended as it will break your system, thats why the Ubuntu Touch is read only system.
