First, is flashing a ROM going to fix my modem issue? I have my doubts, seeing as it was a separate .zip for the Nexus 4, and I don't see how this would be much different.
Second, if flashing a ROM doesn't help, then is there any way to reverse this? I'm very sorry, I just don't have the expertise required to solve this.
Any help would be greatly appreciated. I'm well aware of what I did wrong, and am now seeking help to fix my screw-up.
Okay, so I was an idiot and didn't do enough research. I have a T-Mobile Moto X (XT 1053) and stupidly used stillthisguy's toolkit (which uses Cydia Impactor, RockMyMoto, MotoWPNoMo, and SlapMyMoto) without being aware that it is completely unnecessary since the XT1053 has an unlockable bootloader. Long story short I no longer have LTE, only Edge on a T-Mobile pre-paid plan. I am currently going through the process of correctly unlocking my bootloader and rooting, so I had a few questions.
