[Q] Galaxy s4 is always searching for network
After installing MIUI ROM on my galaxy s4 my network has been messed up I tried installing just about every Rom there is for this Phone. I have data and can text people with a little window coming up and saying no network but it still goes Through. I can only get 4 g and no 3g my phone just doesn't have a signal unless it is connected to 4g. I can't make calls at all, I tried a factory reset and it changed my signal to roaming and I have no data and then I use the Samsung Service mode app and click on LTE and I have data again. Also I tried using Odin to flash back to stock and it always gets stuck at getting pit for Mapping. My brother has this phone too and it work perfect for him, but not mine. Please help I'm all out of ideas.
Also I tried changing the Sim 2 times, could it be my efs is messed up.
