<![CDATA[Ubuntu Touch on Redmi Note 9]]>I am trying to install Ubuntu Touch on a Xiaomi Redmi Note 9 with Ubports. Ubports recognises the device and starts flashing it. After flashing is almost finished, the device boots into UBports recovery and at the bottom of the screen is the following written: failed to save locale to cache recovery last locale no such file or directory. I can try whatever option on the menu, it always boots back to this UBports recovery or another menu or Fastboot. What can I do to get UBports to install Ubuntu Touch?

There is a way to force the update.

eliminating this annoying step

actually there was an effort to do that at least for one port (not Xiaomi)

https://github.com/ubports/installer-configs/pull/299

I know because I actually argued that it could be dangerous. Devs judged that my fears were unjustified, however the PR is still stalled because 3 approvals are needed and one of the code owners has something else to do it seems. So things are advancing at a snail pace on the installer front. Unsure if it will be committed one day, unsure if this solution will be extended to other ports (you'll notice that there were considerations of antirollback protections that could be a blocker for other ports).

I managed to flash the device back into Android and the WiFi is working. However, installing UT with UBports doesn't succeed... It's a pitty that it is so difficult.

A specific version of android is required for technical reasons, mainly partitions and Vendor BLOB's (drivers).

You need to go back to the correct version of Android, set it up and then install UT.

The zip file for the correct Android ROM contains various scripts to flash Android to the device.

If you are on Windows (10 or 11) use the flash_all.bat

If you are on Linux use the flash_all.sh

I guess you are using Windows as you mentioned the C : prompt and tried to run the Linux command in that - it won't work as you can see.

(Make sure you have Android Platform Tools installed as they contain the fastboot and ADB drivers)

What you have to do is totally extract the Android ROM file.
In the folder where the Android ROM file is extracted, open a command prompt - right click on an empty space and choose in the drop down box Open in Terminal.

Put the device in fastboot mode and connect it to the PC.
In the terminal run the command ./flash_all.bat and note the ./ in front of the command.

As it starts doing it's thing, leave it alone and be patient, it can take up to 10 minutes to flash the ROM onto the device and ma seem to hang, but it will be doing stuff. Once it completes, it will reboot, then go through the Android setup and make sure everything works, camera, GPS, wifi etc. Then do the UT install.

flash_all.bat script

Hi, I downloaded the file and tried to use it to flash my device using MiFlash. That didn't go through: I got the error C:\Linux permission denied (but the directory was accessible for all users). Anyway, I don't know why but I decided to use the UBports again and suddenly Ubuntu Touch was installed. However, now I the Ubuntu Touch system cannot connect to the WiFi or the cellular network (but this is maybe a question for another topic?).

Use the fastboot version and run the flash_all.bat script (Windows) or flash_all.sh (Linux) from a terminal with the device in fastboot mode. DO NOT relock the bootloader as it can brick the device and be patient, the ROM takes about 10 minutes to install and may seem to hang at one stage, but it is doing things.

As @developerbayman pointed out, ensure you have installed the Android ROM stipulated by the porter (see the devices page) . If you have done that, ensure you tick all the boxes on the installer "wipe data" and the others. If you did that and are running it through the installer again that is not so important.
