Hey everyone. I'm having a problem with my network after going into the test menu (*#*#4636#*#*). I'm hoping someone can help me out, and hopefully this will also help others in the future that have the same problem. I haven't seen any other discussion about this for this phone.
Background: I was helping a friend re-enable 4G LTE on her HTC Thunderbolt, which the store had disabled for her when she first got it because 4G was not yet available in her city. I figured this was done in the test menu, so I went to it from mhy phone to help her set similar settings.
The Problem: Stupidly enough, because I love tinkering with things, I pressed the menu button (...) and pressed the "Set GSM/UMTS Band" button. My two options were "USA Band" and "Cellular". I panicked a bit, then thinking, decided to select "USA Band". When I did that, I was on Verizon Wireless, and I get LTE data. However, I can't make or receive phone calls. My phone won't ring (though it "rings" for the person trying to call me and they get to my voicemail). If I try to call someone else, it hangs perpetually at "dialing". Setting the band to "Cellular" gives me both LTE/1X data and phone calls, but now I'm perpetually stuck on "Extended Network", which I can only imagine is U.S. Cellular in my area.
Normally, this wouldn't be a problem. I can make and receive calls just fine, data works OK. However, I'm afraid that when I travel and (what I think is) U.S. Cellular, I'm going to be in trouble, and not be able to make or receive phone calls. I need to fix this before I travel. I understand that doing a factory reset or SBF to ICS will solve the problem (please confirm if this will fix it?), but that's my ultimate and final solution. I'm not rooted right now so I don't have the luxury of backing up my app data and text messages, and would like to find a different way to fix this first if it exists. I'm hoping I didn't permanently screw up my phone. Any help is appreciated.
