After installing an AOSP rom, I accidentally screwed with my Sim settings. My LTE and MMS are both broken on all roms that I have tried, and I can't for the life of me get them fixed. LTE sometimes works when I force LTE only, but then I can't make calls or send SMS.
(Just a quick rundown to highlight the main points)
☻LTE won't work unless I force LTE only. (AOSP)
☻MMS won't send, unless i'm on the stock ROM (I've used GOSMS, Hangouts, and Stock)
I feel like I have literally tried everything. Different recoverys, different root methods, different basebands, I've reflashed the APN, and even paid a visit to my friend Murry at Sprint; still no fix. My ESN is still good, along with my MEID. Any help would be greatly appreciated; this has been giving me hell for the past few days.
