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?
This is my first time with LTE phone and it seems like at times I have to go into mobile networks and select 3g then select LTE again for the LTE symbol to pop up? I'm on straight talk and just didn't know if this was normal or if the phone will select hspa signal if its better than the LTE signal ?

i think by default it will when idle fall back to the strongest network cause it saves battery.
but when you need data it will attempt to switch to the fastest available.
cant say for sure but this is what appears to happen on all my phones falls back to 3g and when data is needed it shifts to HSPA+

I'm getting the same behavior on T-Mobile. My Nexus 4, which was never intended to have its LTE radio used, would stay on LTE, come hell or high water, while I'm in the city and fight to keep it as I left. The Nexus 5 seems picky about it's LTE and only uses it if it deems it good enough. If LTE gets 2 bars or lower, it goes back to HSPA. If you force "LTE only" under the secret dialer menu, it will use its LTE, but when you switch it back to LTE/GSM (PRL), it drops LTE and uses HSPA+. I'm like, "The hell is your problem, your highness?"
I had high hopes driving into work today. I was expecting it to get on LTE much sooner, but it didn't switch until I was deep within the city until I entered the parking structure (which my N4 would still have LTE). While I sit here at work, it refuses to switch to LTE while in the building where my N4, in the same spot, would be happily on LTE.
I just don't get it. I thought LTE would be much better on this device, instead it is worse. I feel like this is a bug of some sort. We are in an age where carriers will begin shutting down their legacy networks (of course, T-Mo is nowhere near as ready), and this phone treats LTE like Sprint WiMax!
Not sure about straight talk but I'm in lte with att if I'm in a lte area.

I suppose I should re-flash my phone then. It's just silly how my phone keeps preferring HSPA+ over LTE. When I had LTE enabled on my Nexus 4, my battery life really didn't change. I suppose it had, but it wasn't perceptible to me.
I've had really good luck with it connecting to an LTE network when inside of a LTE area.
However this morning I was streaming from soundcloud while driving and I was 10 minutes into the city with LTE coverage and it would switch. As soon as I ran speedtest it switched. So I believe what was said up above to be true. It needs a good reason probably too switch if your current network mode is doing fine for your current data needs/battery.
I did read this phone is using Qualcomm s news LTE chip which saves power. That could probably play a role.
Either way I'm totally fine with it because it responded to my need of a lot of data instantly by switching to LTE when I ran speed test.
So hey if it saves me battery and h+ is enough for streaming from soundcloud I'm not going to argue with it.
Hold this helps.

Couple of things to keep in mind.
One, your phone will say 3g when not using LTE or HSPA+. This is to save battery, it only shows LTE or H when you are downloading something, or loading a webpage.
Secondly, I have noticed my phone will choose a strong HSPA+ signal over a weak LTE signal. At home, I have a solid LTE connection, so it always says LTE, but at work it switches back and forth from 1 bar of LTE to full bars of HSPA+. Speed wise, they are still comparable, at around 5-6mb/s. At home though, my LTE is around 40mb/s.
Hope this helps.

So, my Nexus 4 keeping its LTE active all the time except for when making/receiving calls was a "bug" of the hacked radio then? I'm not being sarcastic, I just never owned a true LTE phone before, but my friend who has a Nexus 5 says his LTE has been staying on. It really doesn't make sense for LTE to behave this way as it will replace the legacy networks at some point in the future in which you won't have anything else to fall back to.
Oddly, I haven't noticed this at all. I'm on t-mobile, and my nexus 5 defaults to LTE when I have LTE selected as preferred connection. It doesn't switch to 3g during dormancy as far as I can tell (when I turn the screen back on, its already on LTE).

If you don't mind, would you share how to force LTE only under the secret dialer menu?
Thanks.
[EDIT]
I think I found it with the code *#*#4636*#*# -> phone information -> set preferred network type: LTE only
When I do this and reboot, my bars just disappear, and my APN in my mobile network settings disappears too. I'm using net10.
Anybody know a fix to this?

I don't have to reboot, myself. When I force LTE only, the phone drops HSPA and goes to LTE.
I'd say put it back to GSM/LTE Only (PRL) and then reset your APN settings.

About a month ago I was in an LTE area and browsing xda and noticed a radio update so wanting the latest version I immediately flashed it. I noticed on rebooting that my lte wasn't working and I thought that the settings had just been corrupted but after a full re flash of the system and the modem I still can't get LTE in an area where other 4G phones can. However my HSPA+ works fine pulling 20mbps next to a cell tower.
Wondering if anyone can help?

Why don't you flash the old radio on which LTE worked fine?

I did, still no change. I thought that would be the solution too. I might be onto something but not sure? On the APN settings does having the bearer set to LTE make a difference, I never noticed before but noticed that it wasn't set now.
Is there a way to see and change the LTE BAND that my phone is on? Rogers support aws, 2600, 700. So I was wondering if I could manually change between them. The S5 has that option in the hidden menu, so I'm hoping I could do the same on this one.
Thanks.
The phone choose the band himself, if he don't find bands authorized by your phone company, he can't use them.

*#*#46363#*#* > Phone information > Set Preferred Network Type > 'LTE/GSM auto (PRL)'
That's as far as you can get in telling it what network to operate on. It won't let you select specific bands (at least not stock). Mine was set to 'TD-SCDMA, GSM and LTE' out of the box (international version) and since I don't plan to use my phone in China anytime soon, it didn't make sense for the phone to waste resources searching for a TD-SCDMA (China's homebrew 4G) signal. Haven't noticed much improvement to my LTE signal though, still the weakest radio I've seen in a 'flagship' in a while.
Thanks.
I am also on Rogers.
Does that mean when I am on the phone, it will revert to EDGE instead of 3g by using the LTE-edge setting?
I have major issues with reception on this phone.
LTE Works Fine but the 3G/H+ signal is awful, absolute disaster on this phone. It is extremely, extremely weak. And I lose coverage often and over 50% of the times my calls go straight to voicemail because Rogers uses 2g/3g for calling. The phone can't drop back to 2G or 3G in time to receive calls when on LTE
Rly frustrating. Have tried playing with all the settings.

I'm having issues with 3G H+ too. Dont know its CM issue or not coz I had nice H+ signals on Color OS...
Can't even use internet data. most of the time network drops after using internet for a bit.. Network just suddenly gone and after that it comes back with no internet. Internet comes back online after a while...
Really worried.. and annoyed coz can't seem to find any solve for this. Even Mahdi rom had this issue..
I was on a trip recently and I turned off LTE through quick tile because the place I was staying at did not have LTE. Now, I seem to be stuck on HSPA.
I reset network settings and even did a complete wipe of everything and I am still stuck on 3G. I have Preferred network type set to LTE (recommended). I am using the ATT LTE access point (screenshot attached).
Any ideas? Any way to check if it's hardware of software? I am running 44S.
I used to have LTE here and my gf's iPhone 6 has LTE in the same location.

I'd think the only reason it'd be hardware is if something went belly up. Seems doubtful to me as bard hardware is fairly rare. More likely software. A few times I've lost LTE after changing out my sim card, and only the phone company doing some type of reset has 'fixed' it. Not often, but enough to be a PITA.

Add "hipri" under APN Type, save, reboot & see if that helps. :fingers-crossed:
Put your sim in your gf iPhone and let it get an Att signal then put the sim back in the opo that's what I did with my phone and it worked

I tried that. I also put my sim in other OPO and it got LTE. I get LTE with my sim card on OPO thats usually on t-mobile (but his sim did not get LTE on my phone). I also tried my SIM in a nexus 5 and that got LTE as well.
Im fairly sure its hardware failure
