First let me apologize if this has been answered somewhere else before, I've read at least 15/20 different threads that had an issue similar to mine but none of the fixes suggested in those threads were of any help. I cannot seem to find anything about LTE working perfectly on someone's phone then just stopping working; every thread I have found pertains to people losing LTE after flashing a new ROM or while traveling to different cities.
I have a SGH-T999L and am located in Chicago where there T-Mobile does have an active LTE network in place. I have had my phone for almost a month now and have had no problems; I have flashed several different ROMs onto it (cyanogenmod, liquid smooth, pacman) without issues as well. Early yesterday morning though my LTE suddenly stopped working. I have not updated the device or changed anything on the phone or ROM. I haven't even installed any new apps in a few days. I first called T-Mobile, they said their network is working properly in Chicago right now. After determining it wasn't a problem with the towers, I tried reflashing the modem for the device (I got it from this thread: http://forum.xda-developers.com/showthread.php?t=1880987) to no avail. Even though the IMEI was showing up properly I even did a NV restore to see if that would help, which it didn't. I then flashed the stock ROM (UVAMB7) to see if that would fix anything, however the phone is still not picking up LTE. I have even tried doing the diagnostic codes *#197328640# and according to that, the LTE radio is turned on and working properly.
As it is right now, the phone will go through periods where it cannot find any data signal for about 5 minutes at time then HPSA+15 turns on, which also confuses me as Chicago is HSPA+42 market and if I turn on my regular SGH-T999 and set it next to my SGH-T999L, it is able to pick up the HSPA+42 without a problem. Also, the phone hasn't been dropped or anything so I don't think it has to do with physical damage to the antenna or anything like that; literally I had my phone plugged in charging on the table all night and the next day the LTE had just stopped working. I have tried everything I can think of, if anyone can give me any help with this issue it would be very greatly appreciated

You might odin back to root66 and see if that works. If not, triangle away and warranty it out.
Hastily spouted for your befuddlement
start a downliad, then go to Settings, about device, status. what does it show under network type? roms dont always didplay things as we are used to. this will show your true connection.

When I do that, it shows up as UMTS until I start downloading, then it will connect to HSPA+15 then go back to UMTS once the download finishes. The phone network type used to show as LTE before I had problems, sometimes it would switch between HSPA and LTE while I was downloading or loading webpages but it would still show LTE under network type. Now it seems as though it isn't even connecting to the LTE at all.
i wouldnt worry about the hspa 42 so much. it may be the lte devices dont use it in order to save bandwidth for non lte devices. just a theory.
as for lte, you can try flashing the T999N modem to see if it helps. otherwise id agree with the other suggestion. odin flash your root66 firmware and see if it still happens. if so it may be hardware related.

Thank you, I will try flashing the modem. As for reflashing via odin, I tried doing that and the problem is still there so if flashing the modem doesn't work, I'll have to call Samsung for a warranty repair . I just wish I knew why it randomly decided to fail so I don't accidentally kill any other devices lol
Well, flashing the modem didn't work. Hopefully Samsung will be able to repair whatever is wrong with it. Thank you so much for taking the time to try to help though, I very much appreciate it
it could be something as simple as an antenna becoming disconnected, or something wrong with the radio itself. but once you are full stock, and still having issues it pretty much rules out a firmware/software type issue. Leaving the most likely cause to be one you probably couldnt fix.
just to make sure tmobile was correct, id try to go a few miles away and see if it connects though. just to be thorough.

I've been using the Galaxy Nexus for about a month or so and have recently started to notice that the 4G signal will drop whenever I turn on the screen after some time in deep sleep. The signal meter will be fine, until I actually try to use some data. It typically takes about a minute to reacquire a signal, but the phone is essentially useless during that time.
As you can see in the screenshot, there are several red spots where the signal dropped out. I am not in a poor coverage area, and others with the same device do not have these issues. I saw this with a rooted 4.0.2 OTA and am still seeing it with a rooted, deodexed 4.0.4 rom (http://forum.xda-developers.com/showthread.php?t=1481613).
What do people think? Will exchanging the phone possible fix the issue? Is there anything Verizon can do to try and help me out? I'm basically just spitballing here, but this problem is making my phone very frustrating to use.
Are you rooted or stock? I don't have any issues with my 4G on stock or rooted with Gummy 0.7.6. I had an issue with an earlier root where my 4G would drop. I would disable / re-enable and it would start to work again. Maybe try rooting if you are not rooted????

Yes, I see this on rooted stock, as well as the ROM I referenced in the original post (supposedly deodexed 4.0.4 stock ROM)
EDIT: From several posts in the other thread, this issue is not isolated to me or my hardware so I probably won't bother exchanging the phone.

Can you please tell me where you get that HISTORY screen from. Ive checked all menus in settings and I can not find it anywhere.
EDIT... Please ignore my post... I found it...
So, I'm having the same exact problems but i did a log cat to see what might be culprit.
I have narrowed it down to this:
02-08 11:21:51.912 E/IMSFW (415): IIL: Disconnected from '7467' socket
still have no idea what can cause it yet.
also if you switch to 3g it seems it doesn't happen so maybe its a sim problem on verizons lte network end?
11:22:40.029 E/IMSFW (415): ImsSMSInterface: Registration failed, go for retrying if isim nounce present
that's what i found so if anyone can clarify and maybe see if it is really on Verizons end as this is the 4th phone that has had this problem.

Hey fellas, I'm posting in this thread because it relates to the issue I'm facing. Coming from the Thunderbolt, I had no problems holding onto a LTE signal in Atlanta, but with my GNex, the signal just drops a lot (every half hour or so maybe), at work, at the store, wherever. It shows an empty signal bar with a small x, and says 'Searching for Service'.
This seems to happen only when I have it in LTE mode. I switched to CDMA under the 'Mobile Networks' settings window, and it was able to hold on to the 3G signal all day. I am starting to think if it is a LTE sim card authentication issue.
I'm going to VZW to see what I can do (I'm still within the 14-day window).
I'm having the Same issue holding onto a 4g signal in Savannah and Atlanta, cdma only is fine. Let me know what Verizon tells u cause they basically told me to wait for an update

Just came back, basically they said they can't do anything unless they replicate the problem, which they couldn't. (it was a random problem.). They told me to call customer service when I got that issue, so I have to see that at work tomorrow.
I tried a suggestion online where I updated my prl from the 15xxx version to the 52642 version. I did this by creating a contact with the following number
*22899
and dialing that contact. It went through a 'activation' process, with some elevator music, and the signal seems to hold.

To this and post 10, I still have those data issues, but they are much less frequent on the 4.0.2 radio than the 4.0.4.
I got in touch with Verizon wireless online support, and they basically told me to wait till they release a software update. I asked for a new sim card (since I thought it might be LTE authentication issues), and they said it was a software problem, not a SIM problem.
I guess its a wait and see.
Some basic info: Sprint SGS3; rooted, manually updated to LG8. Otherwise, stock.
Since then, I've noticed that my phone doesn't "hold on" to 4G as well as it did pre root and update. For example, the 4G icon will be next to the signal strength in my status bar then it will disappear, there will just be signal strength with no connection indicator then either 3G or 4G will appear. I don't ever remember this happening before root/update. I haven't flashed anything else on the phone, and the main reason I rooted in the first place was so I could easily tether.
Has anyone else had this same issue?
Its funny that the LG8 update was supposed to help users that were having LTE connectivity issues... this happens to me on occasion too. i would venture to say that a combination of LTE still being in early development and coverage being spotty at times even in areas where u may have gotten full coverage at one point plus the "Connection Optimizer" that often jacks with ur data connection switching between wifi, 3g and 4g(LTE)... try doing a ##72786# to reactivate ur phone on the network... this will automatically re-associate ur data profile with the network and update prl info as well...

Thanks for the reply. I'll try the ##72786# and report back with results.
You make a fair point about LTE still getting off the ground, but I will say that pre-root/update, my phone held 4G consistently. Whatever the issue is, hopefully it will sort itself out soon, or enough people will have the same issue that it spurs some action on Sprint's side.
I'm in Houston, FWIW.
Edit/Update: ##72786# seemed to do the trick. HOWEVER, about 15 minutes ago, I attempted to turn on WiFi Tether. My laptop connected with no issues, but about 5 minutes into it, neither the 4G nor the 3G icons appeared next to the signal strength meter. ##72786#'d again, just to see if it made a difference, updated PRL and Profile. Things are holding steady so far, but we'll see how long this lasts.
I'll try to update later in the day.

Glad to see it worked. This is by no means a permanent fix. As u flash different roms thru out ur phones life span its a good idea to run this code every so often as flashing can overtime degrade baseband performance as those files dont get replaced with a rom but different roms interact with those files depending on the tweaks made at software level...

I am up here in Sugar Hill. Sprint Map shows you deep in LTEville. I worked in Tucker last year when a co-worker got a Verizon Tunderbolt. His 4G was screaming. He was getting 40+ down!
But the map also shows Cumming in LTE land so I drove over there just to see what LTE looked like and I saw the icon flicker on for about 30 sec. but it never really was there.

Just flashed back to LG2, so I'll update later and see how things are going.
Hey guys, I just a sprint gnex phone a few weeks back and ran the GNex toolkit v9.1 to unlock and root it this past saturday so I could use a hotspot app for my tablet.
I don't know if this is just a bad coincidence or if I did something wrong..I'm not new to roms and have modded my previous phone (evo 4g) about 50 times, but here's what's happening.
Prior to this weekend I had full signal/bars..Now I can barely get 2..It's mostly sitting at 1 bar and sometimes drops the connection entirely. At the same time, every txt msg I send comes back with an error stating it did not send, however...It does actually go through, twice even. This happens with every text to every person.
I didn't put a rom on it, and I didn't even install clockwork mod...I simply just unlocked the bootloader and rooted it. I did setup google voice afterwards. I can't see how doing this would cause these kind of issues and I haven't called Sprint yet as I absolutely despise their customer service..I'd rather get feedback here first.
The coincidence that I'm referring to is that I'm in Austin, Tx and they're in the process of spinning up 4g LTE towers right now..If by chance they started upgrading my tower this weekend (yesterday & today) then I could definitely see these issues...I walked down about 2 blocks where I do get a full 4g signal, but my txting still had the same issue.
Any ideas or thoughts about my problems?
On one hand, I would tell you that rooting doesn't cause that.
On the other hand, you used a toolkit, so who knows what you ended up doing.
If you haven't changed anything as far as ROMs or mods, then I would suspect you're right about something with the network. The only other thing I can think of would be hardware problems of some kind. That seems a lot less likely though. Sprint does supposedly keep a list of networks that are being worked on. You could check in with them and see if the one in your area is being upgraded.

Reboot your phone and go to about and sprint system update.

Idk why but its sometimes happens for no reason.
Make sure you have good connection first.(go outside)
If that doesnt work update prl to make the network find the closet tower to you.

I was trying that repeatedly hoping it would fix it..but it doesn't.
On another note, today when I woke up and rebooted the phone I had full bars on 4G signal..Thought life was good and then about 5 mins later it was back to 1 bar 3G. That's the first time I've seen a 4G signal here in my apartment so I'm hoping it really is just the towers in my neighborhood being converted to 4G right now.
I've rebooted my phone 3 times now and the same occurrence happens..Full signal with 4G for a few mins, and then it drops to 1 bar 3G..Have updated my profile and PRL and tried airplane mode..Only way to get that 4G signal back is to reboot the phone..Won't stay on 4G though.
I bought a Tmobile Galaxy S3 on new years from staples, and since ive got the phone ive been experiencing strange 4g speeds. While im in my house, I always have full signal strength, and it always says 4G. I live in the Bronx in New York City, and when the 4g is working properly, I get upwards of 20 megabits down, and 1-2 up. Now I could literally be sitting in the exact same spot, and later ill test the phone and it says 0.2 - 0.3 megabits, and like over 1000 ping and the up is so slow it doesnt even measure it. It usually comes back after waiting, turning airplane mode off and on multiple times or doing a battery pull. I find it strange that I can get either 21 mbps or 0.3 in the same house, while always having full bars. In the phone status sometimes it would say UTMS or HSPA, so it does switch from 3g to 4g sometimes. The thing is my previous phone was Nexus S with 3g and im pretty sure I never had a problem loading a simple image in my house because the internet was so slow. I consistently pulled 3-6 mbps on that phone. I tried calling t-mobile 3 times and they give me the same basic crap, like clear your cache, make sure airplane mode is off (really?) make sure youre network mode is on auto (i tried auto and wcdma only and it still gets slow) and all that other stuff. Is there anything else I could try to see if its a network or phone issue?
It sounds like it might be something with your local tower. I would call Tmobile and put in a repair ticket.

Thanks, I just did that. Called t-mobile and just directly asked them to check for tower issues, and they filed a complaint. They said to check back in 3 days, hopefully this gets fixed, or else it might be the phone. Do you think flashing different modems would change anything?

It wouldn't hurt to try. What are you currently running? (rom/kernel/modem)
Sent from my SGH-T999 using Tapatalk 2
Completely stock 4.1.1, with UVDLJA modem, which is the latest I believe. The phone is relatively new so I wanted to try touchwiz before I rooted. Does installing something like cm10 change the modem? Or is it independent of rom/kernel. I saw an application for tmo that can change between multiple modems pretty quickly, I might give it a try.

I work for T-Mo,
If I may lend my opinion,
To me, it definitely sounds like the tower. If you go from 20Mbit down to 0.2, and with 1000ms latency, it's super obvious there is something
wrong with the tower, or there is significant demand on the tower from other users, hey its NYC population density is insane.
Something to note as well, New York City is "in progress" for "network modernization" where they are switching to 1900Mhz.
This is why some people who have iPhones are now getting 3G in certain areas, unlocked devices, as well as AT&T phones can have 3G down there.
Due to this, since there is quite a lot of switching around going on down there, that's probably what's going on.
Example:
http://www.tmonews.com/2013/01/t-mobiles-network-modernization-what-is-it-where-can-i-get-coverage/
Hope it helps.
I see, well that makes sense. I dont really mind if its a tower issue because thatll be fixed eventually, I just would of hated if I had to replace the phone, it would of been such a hassle because I didnt buy it direct from t-mo. Thanks to both of you!
Also, since t-mobile seems to be using multiple bands for 4g, I guess it would be better to leave it on auto in network settings?

If it helps you at all to see if you are on a different band than 1700/2100mhz
You can go into the dialer and do:

Up top mine says band 4
Which is for 1700mhz AWS
BAND 2
which is for 1900mhz PCS.
You might be on band 4 or 2 on a tower by tower basis, or if they are making adjustments
You might be switched but that is above my pay grade lol

Yeah I dont think thats my problem though because my girlfriend has tmobile and she is not rooted but her phone works perfectly she has the s3 and ontop of that everytime I restart my phone the speeds return to normal for like 5 min then go back to the really slow speeds and my plan is unlimited

I have been on the phone with TMO about the same thing for over a month, plus my issue goes a little further. I will lose connection to a tower and not get texts or calls until I reboot the phone.
TMO had me replace the phone and SIM card, then opened a ticket with the Engineers in Las Vegas to troubleshoot, their response was that it was a known issue and would be resolved in the next weeks or months.
Everything ran fine until they pushed out the 4G LTE update, after that the service has been horrible.... even after that update that was supposed to resolve it...
I am wondering if there is a ROM out there that someone built to address this issue as I have about had it...
I am rooted but haven't thrown a ROM on it .... yet

Im guessing you updated your phones softwarem if so, you may want to downgrade to a 4g non-lte radio, and set yourself up on a 4g apn as well. It should help at least until rhey correct their tower issues. 4g is still pretty fast and at least your mms / signal will work as you will be back in the 4g towers instead.
Edit
Actually try this:
Settings--> wireless and networks / more settings --> mobile networks --> network mode --> and select the automatic 4G /3g /2g setting
Then go to access point names and add a new one. The only 4 lines you need to edit are as follows :
Name - Tmobile 4g
APN - epc.tmobile.com
MMSC - http://mms.msg.eng.t-mobile.com/mms/wapenc
And
Apn type - default,supl,admin,dun,mms ( no spaces inbetween the comas )
Give it a shot and let us know if it helps. It should force you back onto the 4g towers which use a different frequency. If you still have issues, then keep all these settings active THEN try an older 4G radio.

Just like pyraxiate up here just said is exactly what i was going to say. Go to this thread right here, http://forum.xda-developers.com/showthread.php?t=2102380 , & flash the last modem which is T889UVBMB4. I was using the T889UVBMD1 modem at 1st & was getting ok service but it just got to the point it was way to slow. I still go back to the T889UVBMD1 modem once and a while with the latest 4g lte apn but 75% of the day it is just way to slow of a combo. Like mentioned id also suggest flashing the T889UVBMB4 modem with the T-MOBILE US apn setting on this thread, http://forum.xda-developers.com/showthread.php?t=2208408 . There's only one page on the thread so it will be right there when you scroll down.

It's screwed from coast to coast. Been back and forth driving from california to pennsylvania, and the network is spotty on LTE within LTE markets, otherwise it runs great until it hiccups.
Seems like you get the equivalent of 'buffer overrun' issues from cd burning. Gert a bunch of data quickly, then stops for a minute to sort it out, then another data burst.
Seems like it happens to deliver a handful of megs of data, then practically loses network service for a few seconds, then another couple megs of data.
Just what i've seen running around nationwide.
LTE is fast when you find it though, nowhere near the speed of my verizon LTE service, but I can live with it.
Hopefully once they finish the LTE rollout it'll be back to normal.
