Android 13 installer script seems to do nothing

I want to try ubuntu touch on my FP5, so I need to downgrade from Android 14 (pre-installed) to Android 13.
I have successfully followed the instructions on the FP page for unlocking the bootloader etc (https://support.fairphone.com/hc/en-us/articles/18896094650513-How-to-manually-install-Android-on-your-Fairphone)

I downloaded the zip file, unzipped it and ran the script. It detects the phone and asks if I am sure I want to continue. I say yes, It then does nothing.

Here is the output from the terminal.

❯ ./flash_fp5_factory.sh

I don’t really know what I should have done differently.

can you share the .sh file?

Is that really needed? Ubuntu Touch is also a ROM, right? The flashing of a ROM would replace anything installed, it would be strange the flashing would depend on a pre installed ROM.

I suppose you can just flash Touch on it? As long as it’s unlocked.

This is needed as per Ubuntu instructions. Ubuntu requires a specific FPOS Android Version. This was always the case also wuth previous FPs

Please check that your device is a Fairphone 5 (FP5).
Your device must be running the Fairphone OS version of Android 13 before installing another operating system. With a previously installed custom ROM, it won’t work! download-icon

Hello
Sorry for the delayed reply. The script is in the zip file at the link: https://fairphone-android-builds.ams3.digitaloceanspaces.com/FP5/A13/FP5-TT4H-factory.zip

I went ahead and installed directly from android 14. Some people on the UT forum said it would work but may result in some things not working.
The installation went well.
