Hey guys I have been searching all over for a solution and nothing seems to work at all. Im on CarbonRom right now, I have flashed roms of all sorts on 4.2.2 and I just cant get 4G on my Galaxy S3 on AT&T. I have the right APN settings, Ive been flashing modems, did the lte fix in a thread in the development section, tried editing my build.prop, tried flashing a different CWM, different roms, dialing *#*#4363#*#* and changing it there, factory resetting my phone, wiping data, caches, everything, you name it. I feel like Ive tried everything but cant get 4G lte on my phone. Whenever I try to switch my network mode to LTE/GSM/WCDMA it automatically switches back to WCDMA preferred. Is there anything else I can try? It doesnt seem to be as serious as a problem for others as everyone appears to have found way to get 4G lte on theirs. Any more ideas I can try? Thanks for your help guys!

Here's the problem.
I installed many roms and kernels on my gnex since i bought it. Lately i came across a strange problem. If i install codename android, gummynex or foxhound with any kernel or radio i'm unable to download over cellular network. If i install android revolution hd or cyanogenmod 9 nightly its work even if i change the kernel or radio ??
Now when i say it doesnt download...my signals bar are max out on hspa+ but it aint blue, its gray. Usually when there is activity an arrows appears to show it. In my case case i only see the up arrow. I also when look under the *#*#4636#*#* menu and i data being uploaded but download is a 0. Ping test didnt work. Signal strength is around -85db. Preferred network is set to GSM/CDMA auto (PRL). I also tried to change it to GSM auto (PRL) and GSM only without success. I played with airplane mode. I tried turning on and off cellular data. Nothing works.
For now I'm on CyanogenMod 9 Nightly Build with Franco Kernel 16.2 and Gaaps 4.0.4 with XXKL1 radio. I have a Bell GSM Galaxy Nexus and my carrier is Rogers.
Does anyone have an idea of to fix it ?
P.S. I tried to wipe data/cache + dalvik + system.
I'd check your APN settings - sounds like some ROMs have the right ones, while the others may not.
Settings --. More --> Mobile networks --> Access Point Names
You can google around for the correct APN settings for Rogers. Here's the first hit I found: http://www.nexusoneforum.net/forum/...gers-wireless-apn-settings-data-mms-here.html
Thx a lot ! It worked ! Thx for your quick reply : )
Thnx since the OP didnt.
Bumping this.
This is my exact issue on T-mo USA. On nearly all radios, that is if I get a signal at all. Upload only no download. I've tried AOKP, Rooted deodexed icl53f, Slim, Liquid. Problem persists. What really chaps my ass is that it came with xxkk6 and now that one has no signal bars at all......
At least I can still make calls and send messages with no download radios.
your APN settings are wrong. read the how in this thread
I have apn set to these settings:
http://forum.xda-developers.com/showpost.php?p=21630221&postcount=1
Which are the same ones generated by using the "Reset to default" option. And what are listed in numerous other sources.
It sounds more like a firmware or hardware issue than an APN problem to me. You've said you tried a few different radio firmwares - have you tried UGLA4? I've had really nice results on T-Mobile US with that.
I'd try loading up the factory image with UGLA4 and see if that works for you. If that still doesn't play nice, you may need to look into getting a replacement.

Thanks for the info. Is there by chance an odin flashable for the GSM icl53f? I keep only returning hits for the CDMA version.

Not for ODIN, but you can get the official Google factory image here: https://dl.google.com/dl/android/aosp/yakju-icl53f-factory-89fccaac.tgz
You can extract it and flash the "image-yakju-icl53f.zip" file in fastboot:
Code:
> fastboot flash update -w image-yakju-icl53f.zip
I was able to restore but on xxkk6 I have no signal to speak of. Will have to go the Samsung route. The postal service has already lost one $350 dollar phone this month. So I'm very hesitant to be honest.

Hi guys
I have problem after rooting DHD with AAHK with gprs/EDGE data and 3G data. GSM works fine, WiFi, GPS also but I cannot turn on data over mobile network. Tried different ROMs, flashing different radio versions, return to stock rooting again and still nothing. Tried to change APN settings, pull off the battery also but no luck. Also I tried with *#*#4636#*#* to switch radio off no luck. Is there any way that I can troubleshoot this to find out what is causing the problem. My radio version is
12.56.60.25U_26.10.04.03_M
Sabsa Prime V8.0 - tried CM7.2, stock, Revolution HD, Jelly Time, Pacman Jelly... no luck
Thanks in advance for any help
I think the problem is with your APN settings. Something like this happened to me recently and it was because my APNs were messed up. Try this app to save your APNs. Maybe there's some error in what you're manually entering. I see no other reason as to why your mobile data shouldn't work on any ROM, especially if you're getting a signal.

Thanks on your reply. I found that the problem was with my operator, because they disabled the data service for my account. I thought that problem is with my phone but it was on their side. Thanks again
Hey there,
I'll try to be as specific as I can about this... So basically, I have the i747 through AT&T but am currently out of the country (in Japan) for a couple months and am using a prepaid data only SIM. Phone is unlocked and data works fine on stock, but I've tried flashing for the first time since leaving the US (with BeanStalk 4.3, MIUI, and LiquidSmooth using first CWM, then TWRP) so I'm guessing this isn't a particular ROM issue.
I'm unable to connect to the Japanese Docomo network when I flash. The phone recognizes the network, IMEI is still intact, but the APN is gone (so I tried APN backup/restore to get the option back, but still no data). Then I reflashed most of the i747u modems, also to no avail.
Also got out my AT&T SIM, which still works on stock. APN shows up, but no voice/data.
Anyone have an idea of what the problem could be? Any other options I missed? As a disclaimer, I don't really have experience beyond clearly written directions posted here, but I read a lot before I try anything and have been flashing my last couple phones with good success.
Thanks so so much to anyone who reads
I can't seem to fix my signal after flashing a ROM anymore. only get 1x which is only better than no signal at all. At one time in the earlier releases of M.O.A.R I was getting LTE and 3G with no problems then later releases I've lost both. I unrooted and went back to stock and my 3G was back and rooted again, went back to MOAR and still no 3G. So now I'm on beenstalk and still cant get a signal. I love both of these ROMS hands down and would like to fix this issue without experimenting with every ROM in the forum. Has anyone else had this issue? I've resetted radios flashed different modems (except MK3) and I still end up with bad network. I need help
Open the dialpad, and then ##72786# . The Device will reboot a few times. Just let it do it's thing. It will go through the Handsfree Activation Process. This will reset your Data.
I am one of the unfortunate few who can't seem to keep a data connection on 4.4 Roms with my Verizon Galaxy Nexus.
I have tried many different things like clean flashing multiple roms, switching out the SIM card, returning to stock then flashing, changing the network settings in *#*#4636#*#* menu, and flashing different radios. Has anyone experienced this issue and successfully fixed it?
