Ok I currently have my D710 on the Straight Talk network and only have talk and text, no 3G or 4G service. It is rooted with JB 4.1.2. I have no idea why i cant get 3G/4G to work. Any help would greatly appreciated!
Did you read through this guide yet?http://forum.xda-developers.com/show....php?t=1995259
You need your MSL to change APNs-http://forum.xda-developers.com/show....php?t=1921045- beyond that I can be of no help because I have never flashed to another carrier
I have already gotten access to my MSL. the getprop ril.MSL didn't work. So I downloaded a APK and it told me what it was. I also got Project X ROM running on my phone. Its WAY better than stock ROM! Loving it so far! This ROM also lets me set new APNs. Stock ROM wouldn't.
But I am not 100% sure as to what PRL should be as well as APN settings.
This would actually be the best place to ask-http://forum.xda-developers.com/show....php?t=1995259
