Did you find any solution? Also trying to get VoLTE back, German T-Mobile... Wasn't successful yet.Sorry for the dumb question .. after I install the zip (1.2GByte?), which app can I use to actually set my csc to the one I need?
EDIT: alright tried to change csc after installing the german multi csc. I need DTM for t-mobile, but phone info shows still DDE as active code. I tried selecting DTM through phone info csc changer, device rebooted, reset itself, but still active csc is DDE.
how can I change my csc to dtm? I am pretty sure that's why my VoLTE option is gone ....
thanks,
polford
