No mobile connection with XperiaXA2

For some time (maybe last SFOS update … that I do not know), I do not get any mobile connection on my XperiaXA2. Everything else works as expected. I tried a different SIM card to no avail, I tried the SIM card on my XperiaX SFOS mobile device: It works. It used to work before on my XperiaXA2. Restarting did not help, reflashing the phone with SFOS did not work. Any thoughts?

I reflashed 4.1.0.24 → no connection
Now I am on 4.3.0.15 → no connection:

I restarted ofono service and here is the status after restart:

[root@XperiaXA2 journal]# systemctl status ofono

Then I removed the SIM card and inserted it again and here is the status after that (no restart yet):

Apr 30 10:57:20 XperiaXA2 ofonod[7372]: No SIM card

note the “No SIM card” at the end. So appearantly the phone recognizes the SIM card but for some reason it is not requesting unlocking it, i.e. entering the PIN code.

Any thoughts?

airplane mode on/off did also not help.

As I am on Linux using EMMA to reflash to Android is not an option.

Thanks.

Edit: I updated to 4.4.0.72 → still no mobile connection
I checked logs of ofono and the only suspicious I see is:

ERROR! Failed to add inotify watch /run/ofono/ril.ecclist mask 0x000a: Permission denied

When I do “systemctl restart ofono” the logs say
