Hi all,
I've been searching this morning on here for issues around Cyanogenmod and LTE, and I've tried following some ideas and help on here, but I'm struggling to get a solution. Cyanogenmod updated itself this morning to CM11. I updated GAPPS and everything is running ok. The issue is that I no longer get LTE connection. I am in an LTE area, on an LTE provider (o2 in the UK).
I deleted my APN's and got O2 to resend the info, and it all looks like it should look (I think) but there's still no LTE.
Is this just an issue with CM11, or is there something more than I can do? Do I need to roll back to CM10 to get LTE? I've read there might be bluetooth issues too.
A lot of whats in this thread seems to be for "Rogers" network in the US, so I'm a bit nervous of doing anything that might screw the phone up anymore than necessary....

Is anyone getting LTE working on CM11? Any help would be massively appreciated if you are. Otherwise I guess I'll wait for further updates.
Thanks all.
EDIT:
For the record, I reflashed, reupdated o2 settings, and rebooted and now get LTE signal. Should have tried before posting. My apologies. Please lock/delete thread. TIA
So you're back on cm 10.2? Or does it work now on cm11?
I'm using CM11 nightlies on my GT-I9195 LTE and LTE has always been working fine.
okay that's weird. i got an upgrade from my provider that includes LTE up to 16 mbit/s... but my s4 mini never connects with 4G...
it wasn't a problem because with 3G i reached up to 14 mbit/s...
but so theres the problem with my provider, not with my phone.

Hello xda. I need some help with my GS3 and LTE. I rooted my phone on day one and have moved from rom to rom. I live in the SF Ba. Area and they are turning LTE on. Using sensorly I found some LTE areas, but my phone won't connect. I have tried different roms: CM10, Paranoidandroid, Ktoonsez, and now Liquid. I started with radio LJ9 and am now on LJ7.
I hope someone can give me a few ideas on what to try next. I heard updating the PRL can help, but I don't know how to do that.
Sorry if I did a poor job of searching, I am on my tablet, on 3G, and I couldn't find much
To update your profile and prl (prl is for roaming and doesn't effect lte).
menu -> settings (scroll to the bottom) -> system updates -> update profile / update prl
I'd odin stock JB or ICS and test LTE that way.
Though all of the ROMs you listed should have perfectly working LTE.
good luck
I flashed back to a Odex stock, and updated my profile and prl (just incase). I still don't seem to get any LTE.

Don't feel bad im goin thru the same thang had the phone four days rooted it the second day i had it NO LTE to date wtf sprints trippin
samsung GSIII rooted
I know! Don't you love paying 4G price for 3G service? Fo real!
Well I'm not 100 % on what fixed it but it suddenly started working. Speed seems a little slow. 5mbps up and down. Don't people get in the range of 10 to 20

On CM10 (and all AOKP ROMs based on it) eHRPD authentication is not working right yet. I think they're close to a fix, but for right now, if you're in an area with a weak LTE signal; you're gonna have some problems
Hello, I am on AT&T on a GSM Galaxy Nexus. This problem has been happening since the the 4.2.1 update to JB and made me root and flash CM just to see if it would solve it (though I initially wanted to because I was curious since this is my first smart-phone).
So the problem is that at work and certain places I get absolutely no data. I can text sms (no mms since no data) and call people just fine but nothing that requires a data connection works since it timeouts. It happens specifically at work. Nobody that has AT&T in my office has problems except me, so I'm ruling that out. Now previous to this I would encounter the problem in very densely populated places like shopping malls or stadiums but I don't think that's the case here.
Here's the other strange kicker: if I switch to "GSM only" instead of "WCDMA Preferred", it works just fine but it's only Edge so it's slow. I have also tried "GSM/CDMA auto (PRL)" to no avail. The only one that works consistently is "GSM only". Once I leave work I have to switch it back again to either of those to to get HSPA+.
I have flashed multiple versions of CM to see if it fixes and since I like the rom so much I haven't gone back to stock. I've done CM10 Stable through M1~M3 and RC1~RC3 to CM10.1 stable and absolutely nothing has fixed it. It is driving me insane because sometimes work is slow and I grow stupidly bored.
Any clues?
Try flashing a Radio. You can find a list in the development forum.

Ok I'll look into it. Also noticed I have a ton of APNs...
Here's a list of what I have:
ATT wap.cingular
ATT Activation Iwaactivate
ATT Broadband broadband
ATT LTE pta
ATT Phone phone
StraightTalk ATT att.mvno

I read somewhere that you should start deleting them or something, but I'm unsure which.
I know I'm more likely to find my answer posting in the thread for the ROM that I'm using but as a new user apparently I can't post in that forum at all. I know the issue I'm having is common with GE 4.4 ROMs, but after having read through threads for more than one of these ROMs, I seem to be the only one having this specific issue.
I'm using the Dandroid 4.4 GE ROM, though I had this same issue with one on the 9505 dev forum too. Even after flashing the updated modem.bin, I'm unable to get 3G service to work at all, at least not for long. I'm not talking about just data either - if I'm in an area with no LTE reception, and anything other than 2G service is selected, I won't get any signal whatsoever. If LTE is available and selected, it'll work, though my signal doesn't seem to be as strong. If I have the phone scan for mobile networks and actually select T-Mobile, 3G service will work briefly, but after only a few minutes it drops out completely and never comes back.
So did I flash the wrong modem or do something incorrectly somewhere along the line? Anyone else having this issue?
Nevermind, I think I solved my own problem. I guess the modem.bin had never flashed correctly, I reflashed it last night, twice, and it seems to have stuck.

Periodically I would not receive texts or calls if I leave my settings on GSM/WCDMA/LTE, enabling Data would restore functionality but it shouldn't be necessary for those lower level services.
I had this issue on the last few builds of official CM10.2 and continues on the CM11 nightlies.
Manually switching to WCDMA preferred fixes issues but only H+ service and it's a nuisance to switch each time. LTE quick settings button has been broken in CM11 since it started. Thought I'll ask if anyone's experiences a similar problem and has a fix.
Currently on the MK2 modem, switched last week to try and see if that was the issue from previous one. I've checked the APN and it looks fine to me, I know I've seen a few variations for T-Mobile, maybe there's a better one.

I've recently seen this happen in cm11 when I'm in certain areas, where before updating to the newest nightly, I would get great signal and still send/receive calls/text. Now for it to work properly I would need to switch from 'lte/gsm/wcdma' to 'gsm /wcdma auto' mobile network.
I have been using Beanstalk 4.4.4 for E980 for quite a while and my phone has been hehaving well. But lately I can't make or receive any phone calls if my network is on LTE. I know that voice is on 3G (HSPA) but when I am on LTE and I make a phone call, the signal switches to H and then it disconnects after I hear one ring. Also, when I receive a call and I am on LTE, once I hit answer, the call disconnects. I then did factory reset and also flashed other CM11 based roms such as Vanir and Blissstalk and the issue persists. I searched on the web and it seems to be an issue with CM11 users with ATT such as Nexus 5 and one plus one users. The rumor is that ATT is experimenting VoLTE in the northeast area (I live in NYC) and that there is a problem in CM11 in that situation. My wife's S4 doesn't have this problem with touchwiz version of kitkat. I can fix this problem by choosing 3G as my preferred network but then I lose LTE speed in data.
So are there any other people experiencing the same problem? Is there a CM fix that I could flash to avoid this problem?
try this
You try changing preferred network to 3G from LTE, and maybe that should fix the issue.
I'm using e980 with CM11 snapshot m11, and starts about a month ago, my phone starting to loose the connection to the mobile network regularly. It happens when ever I reboot the phone, and I have to reboot the phone 2-3 times before it's able to connect again. I switch to the cm11 nightly 3 days ago, as of right now I have been able to connect to the mobile network each time I reboot my device. I saw a few complaints regarding this issue on the cyanogenmod forum. Just thought I share the problem.
