Oh, thank you @ohnonot for reporting, I was looking exactly for this kind of info.
Years ago my XA2 was flashed over android 8 (not even 8.1!) and then updated all the way to SF 4.2.
Now it’s about time to re-flash the latest version of SF on it, but without reverting to Android, i.e. staying on 8.0 baseband (with my skills, the least I do, the better).
Have you already updated to 4.6? Any problems with that?
