I don't know what would cause and hope someone can answer for me been looking but nada. I flashed jelly bean goodness rom to my phone and once everything done and said no signal bars so no calls. So at this point I reflashed one of my other roms and got 3 out of 5 bars signal strength sounds good doesn't it. Well then tried to make a call but never rang so I decided to try to call from home phone but sent directly to voice mail. I then flashed back to orignial jelly bean rom using odin everything went smoothy but have same issue can't call in or out but good signal strength. Does anyone out there know how I can fix this? Also spoke to verizon tech support and they don't know what to do. Please help. :'(
