3G not working but 2G is :S

Guys my phone will not work whilst on 3G. If I switch to 2G all is good.
What is happening?
I rang vodafone and they said nothing is wrong with my account.
I have even done a full wipe and tried a various number of cyans ROM's including the new experimental but still the same issue.
Check APN settings all look good so i'm a bit stuck

APN has nothing to do with it.
No signal? Could be THEY have a bad transceiver. Or there's a lead wall between it and you.

[Q] 4G data works on Sense-based ROMs, not CM -- Credo Mobile

I looked back in the forum a couple weeks for similar threads but couldn't find one that was just like this issue.
On the stock ROM that came with the phone and with the d3rpOne ROM (Android 4.1.2, HTC Sense 5) I can get LTE working fine. I don't think it even really requires any airplane/network mode toggling.
This morning I tried Beanstalk (Android 4.3, CM 10.2) and two different releases of another CM ROM (Android 4.3, CM 10.2 and Android 4.2.2, CM 10.1).
The general instructions with those ROMs were just to toggle the network mode between LTE/CDMA and CDMA only, or to toggle airplane mode. Neither worked.
So how can I fix this? I don't really like Sense-based ROMs, but I definitely don't want to be without a good data signal.

Having the same problem. With the stock ROM, I get 4G. On CM 10.1.3, I can get 3G after toggling the network mode, but I can't get 4G.

LTE works for me using beanstalk with out doing anything special

Yeah, I got the impression that was the norm with most people. I might not have read the full thread, but I did read the first and last few pages and it seemed like everyone got 4G working at some point.
Glad I'm not the only one with this issue, though!

Bump for a new week.

Say open apns
Select lte internet
Enjoy lte
Credit goes to David in the dev forum for the fix.
The APN will change back occasionally so you need to just select lte internet again.
With lte internet selected 3g and lte will work.

That sounds like a good solution, but it's still not doing it for me.
I went to APNs and selected "Sprint LTE Internet". That alone didn't do it. I toggled airplane mode, toggled my network mode, still nothing. I tried both Global and CDMA+LTE/EvDo. I gave it a few minutes for each one and still nothing. Rebooting didn't do it either.
Is there something I'm missing? How do my screenshots look? I read that someone wasn't getting an LTE indicator when they followed these steps, so just to confirm I tried to use my browser. I couldn't connect, so it's not just a matter of the signal icon being inaccurate.

I'm still seeing the same symptoms as Roboslim. Tried the same things, got the same results.

I finally got around to flashing a new radio. Could that make a difference?

When you flash the radio are you adjusting the frequency or band? Sprint uses LTE 1900 are you/can you change that? Trying to find ways to benefit an unlocked phone and take it to another carrier as Sprint sux so bad and has no 4g in my area?

I'm not very experienced beyond flashing self-contained ROMs, so I just got a ZIP someone posted in the Sprint HTC One boards and flashed that without any modifications. It didn't break anything when I went back to a Sense-based ROM, so I'm assuming it's alright.
As for unlocking and leaving Sprint... I'm actually with Credo, who uses Sprint towers. I like them, plus I just started my contract, so I personally won't be leaving anytime soon.

One last bump, I guess.
I suppose if it comes down to it, I can deal with Sense. The system settings really are way too simplistic, but with Widget Locker and a custom launcher it's something I can live with.

Alright one MORE bump. I'm getting the CM itch again. I just gave the MoKee opensource ROM a try and am having the same issue as ever.
Are there any other possibilities out there?

Flash the latest nightly. It should work fine. Worst case do a reboot after a fresh flash when the new ROM is fully booted.
Also try installing the most current firmware.
Make sure you are set for CDMA+LTE/EVDO and also try "home only" with a stock PRL before straying from default.

I have been flashing the latest releases for multiple ROMs and have had the same issue with all of them. I've tried reboots each time too.
Now, I might need some education on the rest of that post. Where can I get the latest firmware? Would that be an official Sprint/HTC thing?
I've messed with a lot of different combinations of settings after flashing these ROMs. I've done CDMA+LTE/EVDO and I'm pretty sure I've done "home only" (would the other option be "automatic"?). As for the PRL, would updating it from the system settings give me a stock PRL?

There is a firmware thread here:
http://forum.xda-developers.com/showthread.php?t=2406330
Download the latest version and flash in CWM or TWRP.
The radios are the firmware images.
Changing the PRL can only be done in stock ROM, or by using QPST. The stock rom is by far the easiest if you have your MSL. Sprint should give you your MSL once you give tech support a call. If they don't then call back and get another tech. (I have never had a problem).
I would recommend using the latest stock PRL. I have noticed that if I try to roam on 3g there is a problem getting data (verizon towers IIRC). I believe that is because it is using EVDO vice eHRPD for 3g. What the difference is?? Well I don't know?
I do know that evdo and 1x still have ongoing issues. So I usually stick with home only to ensure that I stick with Sprint towers. I believe that this is the issue with me connecting to 3g data to my airave as well.
Could you post a screen shot of your APN settings?

I'll have to re-flash a CM ROM before posting a screenshot, but from what I recall my APN settings looked like your image. I had "Sprint LTE Internet" selected. I'll flash the latest firmware from that thread while I'm at it.
As for the MSL, I'm not getting my service directly through Sprint. Would I get the MSL from my carrier, then, or would I have to get in touch with Sprint somehow? Do you know how that works? Either way, that'll probably take a little more time and waiting around than just flashing some stuff.
Once I get that MSL, what are the steps to set my PRL?

Who is your carrier? Did you buy the Sprint version off contract?

Only getting 1X Data - Verizon

Hello:
I searched for a while on the forum and did not find any reoslution.
My N6 is from GPS with a cut SIM card, running custom ROM/kernel. Have had no data issues and have had LTE for a few weeks now with all running perfectly, but since yesterday I can only get 1X and occasionally 3G. I did not alter any of the cellular data settings.
I obviously cannot function with just 1X. I restored a few backups and played around with the cellular data settings. Nothing has worked. Can anyone assist with how this could be resolved? Is it a data settings issue?
HELP!
Many thanks!

You stated you didn't change anything so how could it be a settings issue?

Whereas I didn't alter any settings, sometimes things can just get glitchy and toggling settings or editing a build prop etc. can cause a fix.
So I was able to fix the issue and here is what I did (posting in case any other users encounter this issue):
1. Restored stock root backup
2. Had 1X
3. Went into cellular settings
4. Changed from global to LTE
5. Enabled the data roaming
6. Rebooted
7. Had 4G
8. Backed up for safety
9. Reflashed desired rom/kernel
10.4G remained.
Thanks...hoping this doesn't occur again.

Sprint Nexus 6 Data Issues

I'm on a Sprint Nexus 6 running 5.1.1 (Euphoria) and have issues with my phone connecting to LTE. I will often leave the house or work where I am on WiFi and then it will connect to 3G where I should have LTE. If I put it in airplane mode and then back it will connect to LTE like it should. Sometimes it will even require a reboot.
I've tried different Roms and even returning to stock and still have the same issue. How do I fix this?
Thanks!

Are you set to Global or LTE (recommended) in cellular networks settings? Also, in developer options, you can set to aggressively hand off to data from WiFi.

Was on Global, will try LTE (Recommended). Also just FYI, it will even occur if I'm out driving around and not connected to WiFi at all. It will switch to 3G and won't switch back until I toggle aiplane mode again or reboot.

It may be hard to believe but it may also be a sprint issue. Try the dialer code if you're on a stock ROM. *#*#72786#*#* select reset.

Unfortunately still having the same issue with Global and aggressive data handover on. And I'm on AOSP so the dialer code and carrier settings under mobile networks will not work. Any other ideas? Thanks!

Honestly, I'd flash a stock backup or a stock ROM. Then go into carrier settings and update PRL and Device config. Then flash AOSP again and see if it's any better.

I've tried AOSP a dozen times while on Sprint with different devices; not once have I been able to get data/mobile to work.. Just gotta stick to stock ROMS.

Have you tried using the data fix zip in the OP? I've flashed a bunch of stuff and only once couldn't get data going. ???

This seemed to have helped so far. Must have reset whenever I flashed a different radio while on AOSP. Thanks!

Resetting 'band' setting changed from test *#*#info#*#* menu?

The short:
I changed the "Select radio band" setting in the test menu (*#*#info#*#*) and it screwed things up.
I wiped and reflashed CM12.1 - but it didn't reset that setting (it's still borked).
Does anyone know where it stores that setting, or how to reset it somehow?
The long:
Initially in CM12.1 I was having problems staying on LTE - it always fell back to 3G and stayed there.
So tried this band change that someone who had the same problem suggested.
Now, every option I try is great for LTE but says "cellular network not available" and I can't make calls.
The exception is "Cellular" which I can make calls but only get 1X data.
These are the options in the menu:
"JAPAN Band (WCDMA-800/WCDMA-IMT-2000)"
"USA Band (GSM-850/PCS-1900/wCDMA-850/WCDMA-PCS-1900)"
"Cellular (800-MHz)"
"PCS (1900-MHz)"
I don't know what it was before and I can't see figure out how to tell what it currently is set to.
I just want to flash back to stock so things work again, but if this setting doesn't get reset then I don't know if that will work anyway.

Any chance settings like that are stored on the SIM card?

I seemed to have luck when I made the changes according to this post and then immediately ran the ping test. I don't know if the ping test really did anything to help but I've had cell service since following these steps.

Unfortunately that's what I did initially. The setting in that link ("Cellular") made my calls work, but I could only get 1X data.
So somehow by just flashing and reflashing different things (including failing to reflash to stock), it's back to where it was when I started.... which sucks, but is at least useable. Calls work and data works, but the first time it has to drop back from LTE to 3G, it get stuck in 3G forever (until airplane mode). Super sucks since it's my primary home router tethered. I have to airplane mode like 5 times a day.

Just in case someone else ran into this problem, I ended up getting a new sim from Verizon and everything's working now finally. It still says "000000" when it's in 3G, but I don't care about that - it works and it goes back to LTE when it can, rather than staying on 3G forever.

Works for Moto X play - should work for others too..
I too did the same mistake. Changed my Band to "USA" and couldn't restore to previous despite Factory reset.
The SIM 1 went into 4G data only (No voice) , didn't recognize 2G & 3G network for any sim.
However Sim 2 worked fine for 2G,3G & 4G.
i came across a thread in XDA, and after breaking my head over how to execute it, I finally did it.
I have written a brief guide to it. Here's the link.
