@luksus thanks for your answers. I have just finished installing UT and the installation was seamless. I'm impressed with this ubports-installer.

@MrT10001 Thanks. I've reflashed with the UBports installer and the phone is back!

I saw there was an OTA update this morning and I installed it. My phone rebooted to install the update, then rebooted again and has been on the boot screen for several hours. Should I not install OTA updates?

I guess I need to reflash using the ubports installer again?

I have bought a brand new Fairphone 3+. It is running Android 10 but is prompting me to upgrade to 11. At the moment the Fairphone website only provides links to Android 11 images.

So I have two questions:
Q1 - I think I already know the answer to this, but I want to check: the ubports FP3 page currently says Ubuntu Touch OS for FP3 is built on Halium 10.0, therefore needs Android 10? Therefore does this mean I must not upgrade to 11, and if I do, then I won't be able to install Ubuntu? I also believe it is then not possible to roll back Android to 10 from 11, is this correct?

Q2 - As I cannot find any downloads of Fairphone OS Android 10, I cannot restore Android 10 can I? So if either the install doesn't work, or if I decide I don't want Ubuntu Touch OS anymore, then I must install Android 11?
