Been running Darkside rom for several weeks now without any issues. Just picked my phone up to check it and it says no service and "searching" but never gets signal. I took the sim out and used it in my other phone without any issues. I have the replacement warranty if I need to swap it but is there anything I could try before I do that and return it to stock? WifI calling does work but with Wifi off, no cellular service. Thanks.

I had this with my old iPhone. It usually happens when its baseband crashes. For some reason jailbreaking always did that to it.
Just reboot your phone. If it happens very often you might have a bad flash.
It is working again. I think the 4G must have been out in the area because if I selected GSM only it would get edge. Thanks for the replies.
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 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.

Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...

Hello
I've just bought a new galaxy ace 2 and I am experiencing some problems.
When I'm using only gsm network type (i think, now I'm testing HDSPA), typically, when I'm logged on icq, mobile sometimes loosses signal and displays there is no service. After few seconds is everything OK and network is back at full singal. This can be seen also in battery usage view, when I'm having always yellow line with thin red places.
I'm now using it with mixed mode on HDSPA and there are no problems with network.
The phone is under warranty, so there is no problem, but I dont have much time and first I would try other solution. I tried to flash it with odin to same fw, but no change. I tried to google it but I didnt find any solution. Could you give me advice?
Thanks for answers

Well the "train" issue is due to the train being like a faraday cage, blocking the various microwave signals, the reason you get a signal on a train is because they have amplifiers to retransmit the signal into the train and vice versa.

I have noticed that there are people starting to notice that that have LTE in their frequenting areas, but it's messing with their data once they leave these areas.
For me it was having issues kicking back to edge and even 4G signals would not pull any data, would simply say that I had no connection. Didn't matter whether rooted or not or which rom I was using.
Anyway,
I have discovered somewhat a fix for this issue.
Under Connections tab in Settings, click more networks, then mobile networks, then Access Point Names my Access Point Name was epc.tmobile.com.
I noticed in other forums their APN should be fast.t-mobile.com so I thought I'd give it a try and incredibly my results were pretty good. It goes in and out of LTE areas pretty smoothly in comparison to losing data altogether.
Give it a try and report back.
Thanks
I was experiencing drop of data connection for long period of time (at least 5-10 mins) every time I leave the house, losing my wifi connection. More than once it just won't connect at all for a good couple of hours. I just did a test today, messing with the APN, network operator settings and get it to connect to 4gLTE. Once and turn on and then off the wifi, I lose the data again. And it wasn't gonna come back.
The fast.t-mobile.com address seems to do the trick and I'm now immediately on 4gLTE after losing wifi. and the speed is AMAZING at 24,000kbps download and over 10,000kbps upload.
Thanks!!!

great find, I must have switched between 5-7 different roms trying to figure out why I'd lose data for up to 20min. after coming off wifi. Once I got reconnected to 4g I was afraid to even turn my wifi back on.
This seems to me to have just started recently, I'll have 4G but I might use the elevator at work and lose my connection, upon being back in service I'll be stuck on Edge for about 10-20 minutes before it picks up the 4G connection again.
I've been switching to Airplane Mode then back and that seemed to help but it doesn't any longer.
My APN is already fast.t-mobile.com, is there any other solution to fixing this?
EDIT: If I reboot my phone it connects to 4G immediately, and I'm using a Rooted Stock MDL Build w/ the Faux kernel.
