[Q] 3g not working since 4g outage

Ever since the 4g outage my thunderbolt is no longer able to connect to a 3g network. Whenever I leave a 4g coverage area it goes immediately to 1x. I've got LTE on/off and have tried both "CDMA + LTE/EvDo auto" and "CDMA auto (PRL)" and neither get me connected to 3g.
My Thunderbolt is rooted but is running the stock ROM that came with the original root instructions, not running a custom ROM. I haven't done much if anything to customize it.
Any ideas on how I might be able to fix or troubleshoot this?
Thanks in advance.

It is not your device.
Verizon is still reporting various outages as they are still updating the LTE network.
I have more or less the same issues from time to time since the outage and I can mostly get back to 3G by doing a battery pull when I'm in a known 3G area.
When I'm in a 4G area the only way for my device to revert back to 4G is again to do another battery pull. As I write this my weather widget will not update even as my device shows that I'm in a 4G network. To verify that it wasn't just my device I look at another TBolt here at work and the same is happening to that device.
Hang tight is all I can offer.

did you update your radio? if you're rooted, you may not have gotten the pushed update for TBolts that updates the radio. try flashing the new radio file. 4G works great on my stock roms.

No I haven't flashed anything - where can I get the updated files? Is it a whole new rom or can I just update the files?
BTW pulling the battery seems to have fixed it - now seeing 3g/4g switching. Although the last time I was in my hometown there was 4g here and now there's not. I suppose that's Verizon working on their network.

I had the same problem. 4G would work but in a 3G area I got 1X. So I rebooted the phone and it fixed the problem. Can you try that?

[Q] new to NS

Hey, I recently just got the ATT version of Nexus S, running on T-Mobile. I HAVE 4G data in my plans but with this phone I am not getting 4G. I am understanding that this device is not a 4G device so I should at least be getting 3G (3.5) you think, but I am not even getting that. I am getting 2G only. Any ideas?

setting-wireless/network-mobile network-uncheck use 2G only...

The ATT version is not compatible with T-Mobile 3G (which is why it is the ATT version)

I have the exact opposite problem. I have a T-Mobile Nexus S on At&t...only get 2G

then you 2 should exchange your phones....

[Q] No LTE on CM10 M1 VZW GS3

I have not seen 4G on my device while standing next a person with 4G. I have 3G data, I do not know what is different now. I have checked the Mobile Network Settings but still no go. Any suggestions?

[Q] 4G not available anymore?

I've been flashing a few 4.2.2 and 4.3 ROM's lately and all of the sudden I don't get 4G LTE anymore, it just sticks at 3G when there is complete coverage. Any suggestions?

[Q] A question about modems and networks (Straight Talk)

I have a Strait talk SM-S975L galaxy S4 running Kit Kat insane rom android 4.4.2. Baseband version S975LUDUANB1. I have noticed with both this and the factory stock that my 4G and 4G LTE signal completely disappears (I lose all data connectivity and can only call and receive sms) in the town that I work, no 3G signal, no H+, H signal nothing. This is about 15 miles from my home town where the 4G/ 4G lte signal is great. I used to have a straight talk galaxy S3 that worked fine in this area. When I spoke to straight talk technical support, they told me the reason is that the S4 doesn't work well in this area is because it runs off AT&T towers only, and not both AT&T and Verizon(unlike my S3). My question is this, is there a way to flash the modem or do some other hack that will enable me to get a signal off both towers, like my S3 had? Any help would be greatly appreciated, thanks!
