I've tried running multiple ROMs, CM10, CM11, AOSP, Carbon KK and for some reason, for each of these ROMs, the data doesn't seem to work. I have full reception and everything works well except I can't seem to get any sort of data transfer.
The only time the data works is when I restock the phone back to ATT I747 UCUEMJB stock ontop of installing the Modem CWM I747UCUEMJB.
I'm currently running AOSB Kitkat 1.2.9
Kernel version 3.4.79-cyanogenmod-g29c22cf
Modem CWM I747UCUEMJB
Any thoughts on how I can fix this data problem?
