Hi, I stay in English, so others can read this too.
(Short in german: WLAN hat funktioniert, SIM-Karte nicht. Das adaptation-common Repository war noch von 4.3.0.15. Geholfen hat dann der Austausch auf das korrekte Repository.)
In my case WLAN was working but the SIM card (Vodafone) could not be detected. The solution I found in
(Thanks to everyone there.)
“ssu lr” showed an adaptation-common repository from 4.3.0.15, all others were from 4.4.0.58. Since WLAN was working from a computer I used Putty logged in as nemo and then devel-su. I did:
ssu re 4.4.0.58
ssu rr adaptation-common
pkcon refresh
pkcon install ofono-ril-binder-plugin
A reboot was not neccessary. Immediately a pin code for the SIM was requested on the XA2 and everything is fine again.
