Ugh! Very sad to hear this. I looked at my IMEI and it has a number, so I don't seem to have the exact same issue, but I fear I am in the same boat. Do you think this is a hardware problem?
I tried this, and either I did something wrong or it just doesn't work because it didn't fix the problem. I used Matt's utility 1.82 to restore ICS. The restore went fine, but it wouldn't fully boot as expected. I then installed the JB OTA via recovery, but still no 4G. Is there a way to ensure my radio has the right software?
Went to Verizon today. Got a new SIM card. Didn't fix anything as expected. Verizon told me that I am over a year so no warantee and I don't have insurance. So my only option there is a full price replacement or live with 3G until late August when I can get a new phone. Ouch!
Any other ideas? I'm desperate and will try anything. 3G is extremely painful after being 4G.
Thanks!
I started reading this thread earlier today because I couldn't get anything but 3g for the past couple of days. Like you said, my IMEI has a number (unlike BigDaddyHicks) so I was hoping the radio wasn't corrupt. Anyway, my point is mine is back on 4g now. Unfortunately I don't know exactly what I did that fixed it. I hope it stays this way, it's been on 4g for a couple of hours now. I had tried rebooting, and airplane mode on/off, and those didn't work, sometimes it would say 4g for a few seconds to a minute but then it went back to 3g. I tried switching between global and LTE/cdma a couple of times, and pulled out my SIM and wiped it off and those did nothing. I tried to install the motorola restore connectivity app and it wouldn't install, then I tried the LG one and it installed and ran but it crashed at the end and force closed. After all of that I powered the phone off completely and waited a minute and powered it back on and it's been on 4g since. My problem may be completely unrelated to your problem. But if you haven't tried everything that I mentioned you might wanna try them, even the LG restore connectivity app, just to be on the safe side... Good luck!
