Update : After several tries Ubuntu starts on my FP3.

I loved Meego Harmattan and my N9
I used a FP2 with UT, and liked UT
I used LineageOS on my FP3 (I don't like Android)
Now using SailfishOS on my XA2 (And love SailfishOS)
No I can use UT on my FP3, nice.

Next PureOS on my Librem 5 and Sailfish/UT/Mobian on my Pinephone

Hi community,

I wanted to install UT on my FP3.

I failed all the time, my phone stays on the boot screen showing Fairphone name and Powered by Android.

I used differents UT installer versions.
I first installed FPOS 9, then tried with FPOS 11 and FPOS 10

In the UBports documentation I didn't see how to manually flash the device using abd.

This is why I'm asking for your help.
