On my Xperia 10 III the update to 4.4.0.68 itself went smoothly and without any problems.
But after the update I was faced with the ‘IPv4 mobile data connection not possible’ bug again:
After hours of trial and error, the only solution was a full re-flash to Android 62.0.A.3.109 and then back to SFOS 4.4.0.68.
However, i really don’t want to do this procedure with every update.
Does anyone have any idea what could be causing this problem?
