Flashed touchwiz jellybean Rom. Had no lte. Flashed back to rogers original 4.0.4 and no longer have lte or 4g. Do I have to get into an lte area before It registers? I have my tab with me and it's getting 1 bar lte 4g in a weak area. Please help.

Go into your Mobile Network settings, check "Access Point Name" and see if you're on the LTE apn.

I've had the same experience with three other roms I've flashed on my roger gs3. I have been through apn settings on all of the roms, but I still dont get LTE. When I recover the stock rom it goes back to 4g/lte every time. So, I'm sticking with the stock rom until there is a definitive fix. I'm nowhere near good enough at this to figure it out myself.
I suggest, if you want to keep receiving lte service, that you restore your stock rogers rom.
From what I've been reading on xda threads; it seems that this problem is central to the at&t/rogers/bell phones.
Roms I have tried:
d2can OTA keeproot
aokp_JB_d2att-ota-eng.task650-ktoonsez-10.3.2012c (this one is so bad ass; I might just put up with no lte)
Liquid smooth d2att jb v.2.0
NexusMod-Triune-II-(UX)-20120918-NIGHTLY
Are you basing the no lte status solely on the icon in your notification bar, or have you ran speed tests to confirm your network speed?
speed tested everytime

No, unfortunately, when experiencing these 3g/h+ instead of 4g/lte problems, on the flashed jb roms, my download speeds are consistently under 5mb/s. When restored to stock rom they go up to almost 10mbs on 4g. I haven't been able to test the lte speeds yet because rogers towers somehow manage to miss my street, but are covering the college five blocks from here. I'll test again next time I'm on campus and see how they both fare.
There seem to be so many variables involved. I'm just trying to eliminate them one by one, so as not to confound the results.
I was thinking that the aosp roms don't usually have an lte icon.

I had to give up on ktoonsez &task rom and go with CM10 nightly. This is after trying out cm cfx official rom, to no avail.
I was able to get 4g with cfx, task 650&ktoonsez,but only for a short time then they would automatically either lose signal, or switch to a different APN all together. Now I have around 13 mbps on CM10 with H+. I'll settle for that instead of sketchy hit or miss with the others. I'd like to figure out how to fix Task650&ktoonsez rom. I prefer that one so far after playing around with them all a bit.
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.

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
This is the Task650 and Ktoonsez AOKP. VERSION: d2att(4.1.2 JZ054K) from December 2nd release.
My data network goes in and out at random. It actually started happening about 4 days ago on an older build by Task650 & Ktoonsez but I saw the new one so wiped dalvik and Partition cache and rom'ed. Even after flashing the new ROM, data is acting the same way. It is completely random, happens when the phone is in use or when it is locked. I can tell when data connects for short spurts because I hear the notices for new emails. All in all today, I've maybe had 5 minutes of HSPA/3G data and the rest all I have is cellular network for calls. reception strong, and I am in areas where I always have good connection and speed.
Any ideas? Kind of frustrating if I am out to lunch and want to catch up on things (stuff is blocked at work). Also I am paying for data I can't use :/
fully wipe and reflash.. try a different modem

I am admittedly new to flashing, I just assumed everything was in the package. I flash the ROM and Gapps, is there a source for different modems?
This is definite disconnect of data DHTP. Can't get anywhere, and there is no symbol where there usually is on the reception bar. When it comes back for brief moments, it has either HSPA, 3g, etc.... on the bar.
are you able to send and receive calls? text?
I flashed that rom three days ago, and i had to replace it via warranty. it showed it had signal, but couldnt make any calls or text at all. then i Odin back to stock never worked again.
Don't think it has to do with any rom. Noticed that my wife's sgs3 has had a problem sending and receiving texts and the network drops a lot as well. She is completely stock with the jelly Bean update. My network has been a little suspect over the last few days also. Might just be the service.

Hey Guys, I may have found the culprit...sort of.
The wife has an iP5 and she said to me while we are driving to a holiday party 'I finally have official 4G LTE on my phone'. To which I of course ask what she means. Apparently the same day I started not being able to connect to data networks, is actually the day that ATT fired up their 4G LTE tower(s) in the Lehigh Valley area. When I do get data on occasion, it's when I bump down to 3G and HSPA. Unfortunately, the ROM has a bug where I cannot force it to look for just 3G, I go to save the setting and it immediately jumps back to LTE.
I may just have to flash to a version that definitely supports 4G LTE data. This issue occurred before I flashed to newest ROM, so it has something to do with the core build or modem that both versions use.
Ngriffin, if you find any successful modems please let me know. I like the ROM but I can't go without a data connection much longer.
So, for those who care, I flashed Gapps and also Flashed a new modem (http://forum.xda-developers.com/showthread.php?t=1831898) version UCLG1 and it's a no go. A few in my area said it worked great for them so now I am a bit discouraged. Northeast Pennsilvania Area.

More info, tested using the Wife's Ip5 and realized we don;t have LTE at our house, so I'll have to wait until we get withing range of the LTE tower(s) to see if it has an issue. However, I now have data reliably.

That's normal. LTE is data only and isn't used for phone calls.
I've been running Task's AOKP on my SGS II and III for a while with no data issues. Check your APN settings. If you're in an LTE area, you should be able to sit on the ATT LTE APN and have no problems, even away from LTE coverage.

To update further, LK3 modem worked for a short while, but once I left the area of my immediate cell tower and it had to connect to another tower, it couldn't. I flashed ALL modems in my list a post above and NONE work. I'm kind of pissed right now.
Any ideas? I'll probably to a full backup and then flash a completely different ROM and cross my fingers. Is there an official JB stock ROM sans the bloatware that is stable and can connect to LTE (or any data network reliably for that matter)?
It was my APN *facepalm* Thanks for the suggestion. It was sitting on wap.cingular instead of the LTE and it was causing the issue. I'm on modem CLH1 and it is working, I have the 4G (3G) symbol now and data is connecting. Well, I learned something thanks! :victory:

I started having issues with mine about the same time. I haven't been able to figure it out yet. I had just gone to JB and flashed a new ROM. Then started noticing not just data being very spotty but also my calls (both incoming and outgoing) were very spotty too. Both seemed to only work about 50% of the time. I have since completely wiped and factory reset twice. I even Odin'ed back to a stock Rout66 jelly bean system but I still have issues
I have updated my APN to ATT PTA but that hasn't helped. What APN settings did you go with? Is ther some specific for LTE coverage? On the stock system now I can actually see the LTE icon when it actually chooses to connect.
Also, where did you find other modems. I was told in another forum not to flash any that weren't specific to Jelly Bean and all I have found is the stock I747UCDLK3 which is already on my phone. I did try flashing that seperately just to see if that would help but did not.
I need to get my phone working pronto as it is my main phone for both business and personal phone calls. Any help would be greatly appreciated. Thanks in advance.

When you're on stock, only thing you can do is check with your carrier and they'll either tell you that it's something on their end being worked on or that your SIM card is faulty.
This happens to me on tasks AOKP ROM at least once per day, but it usually only happens when I turn on LTE. Basically what happens is the phone has cellular service but no data, after a few minutes it comes back. What I have noticed is that its to do with LTE so maybe there's a problem with that?

Task's AOKP doesn't set the default APN to LTE for Rogers so you might wanna make sure it's your default APN.
I have been having some serious issues with data ever since rooting and flashing custom ROM on my Galaxy SII which is on Boost Mobile. When i first got the phone before i did anything to it, i was getting pretty good 4g and 3g speeds. After rooting i noticed that my 4g and 3g speeds had dropped significantly. I called boost they said there is some work being done in my area, which i think was crap. I was running baked ROM 4.2.1 JB and it ran nicely but i had no 4g connection by this point and had only 3g connection but VERY slow. I thought to restore my saved backup of rooted stock and maybe my speeds will come back. NOPE 4g still doesnt work at all and NOW 3g doesn't work either. I've checked APNS it seems to be correct, but my connection status is still "mobile network state disconnected" . Oh, also i've tried flashing different modems and kernel repacks cause i know using custom stuff can bork ur 4g.
Can someone help please?

Right now i am on Stock Rooted, Using modem FI27. Before i was using baked ROM as my daily driver on FL24 Modem, thats when i noticed 4g had gone completely. I am using AGATs kernel FI27 repack. Its strange though my baseband says Fi27 but build number says FL24 on the end. Should it be that way?
oh btw my 3G came back, it just took forever to connect. But my 4g still wont work, it connects to the network but it still says "mobile network state disconnected".
I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

stock lies to and shows 4G all the time, cm10 and show the truth. the s3 sets at 3g until data is needed then transfers to 4g
