so i bought a T999l a few weeks ago had it unlocked, rooted and activated with my existing t-mobile account. For some reason my 4G never worked with them and after several calls they said because my phone was modified they couldn't help me basically. I started with some of the roms from this link http://forum.xda-developers.com/showthread.php?t=2308514 but ended up going back to stock or prob trying to go back to stock because it still says its modified in status of phone. so i was back to 4.1.2 with uvamb7 kernel. I ended up trying sim cards from different carriers and found out that 4g works with at&t sim cards. so the other day i joined aio and finally had 4glte for the first time on this phone. As the days go by though i started noticing it wasnt keeping 4g or 4g lte when i was moving around. As a matter of fact i have to force it to go 4g or lte by either restarting and getting lucky or by using *#2263# and switching sometimes several times from only lte and gsm to automatic or all lte basebands (which gives me lte but i cant make calls or receive calls apparently) and then switching to automatic. Basically if i get lucky and its getting 4glte on automatic it will be fine until i move to a area where there is no lte then its gone until i force it to go lte again even if i get into a area that has lte/4g. Its like its not automatically detecting its in a 4g/lte area, it just stays on edge until i force it. I then tried the 4.3 rom at this link http://forum.xda-developers.com/showthread.php?p=48399478. I sort of got it working but i think i might have been using the wrong kernel because whenever i restart the phone it doesnt load past the galaxy sIII splash screen. If i dont restart however it works but same issue i have to force it to detect when its in a 4g or lte area. So since that wasn't working too well i went back to the stock 4.1.2 setup. So im thinking is this an issue with my antenna or something? I'm still learning this phone so any input would be appreciated. Thanks in advance
If your had updated to stock 4.3 and if the latest version from Samsung contains KNOX in t999l variant, follow this step !
reboot into recovery mode and clear the cache and restart the phone! this should work..!

i found a t-moblile 4.3 firmware update last night and flashed it using odin. Seems like its not rooted anymore since i'm getting the stock recovery now. I assume wipe cache partition is the same thing right? so i did that and restarted the phone. 4g lte came right up. I make a call and it drops to 4g which is fine considering before it would drop all my data during a call. Here is the thing though after the call it shows full 4g for a couple seconds then no bars, nothing. No data no network and it will consistently do this . im starting to think this phone is possessed
Stop flashing stuff. Odin to stock (4.3 if you have ever flashed 4.3 via odin, 4.1.2 otherwise) and bring it in.
Also, make sure you use the right firmware, or you will hard brick. If you have never flashed 4.3 via Odin, use MB7. If you have flashed 4.3 via Odin, use MK4.
No amount of flashing random stuff will fix your nv data.

I did flash MK4 and i bought this phone off ebay. I don't have a warranty with it. Where exactly am i bringing it in to?
If you have the t999L it has warranty... Hasn't been out long enough for warranty to run out
Bring it in to your carrier (tmo?) And have them reprovision it. It sounds like bad nv data, and unless you have a good backup, the carrier is the only one that can fix that.

I have the same problem, I paid 15 dollars to the unlockpros.com to remotely unlock my T999L. they did unlock it but now 4g data in t mobile is gone, it freeces, on aTT I get 4G but it goes on and off.
I spoke to them and they tried to fix it remotely, the 4g finally appeared again on t mobile network but then after restart same problem again, no 4G data on t mobile,
does anyone has a full NV data backup that I can use to restore?
will a NV backup from another gallaxy 3 work on mines??
hope someone can help.
Don't use anyone else's nv data, major problems if they turn their phone on ever, and legal issues.
Just Odin the root66 mb7 full restore. That will put you to 100% stock, but with root. You can then use triangle a way to reset the flash counter and modified status, then bring it in to tmo. Make sure to tell them not to update you, or you are stuck with the new bootloader. They might update you anyway "for your convenience", just FYI.

Anybody ever have issues with apps? I first had an issue with the stock messages app not allowing me to send out texts to a single person. Been having this issue for about 2 months. Have been in touch with T-Mobile repeatedly and they reset the signals and everything each time to no avail. Last rep I spoke with said to bring it in to a T-Mo store and get them to change out the SIM (in case that was the issue) and get them to do a back-up & reset. That too did not help. Eventually I downloaded the Google Messaging app and through that I'm able to send out normal person to person texts again but not through the stock app.
I've also got issues with apps having updated versions yet the updates aren't available in Google Play Store for me to download. For example, on June 27th, NCP Mobile came out with version 1.8, but it's still not showing. I've been in touch with the National Consumer Panel, and they say as long as I'm running Android 4.0 or higher (actually running 4.3, rooted- stock ROM) I should see the update available.
I've also been experiencing issues with Perk apps (namely Perk Browser and Perk Search & Win) not allowing me to sign in via Facebook or with email and password. Password reset links almost never get sent. The 2 times they did finally send me a reset link it directs me to the Perk homepage also on which I cannot sign in. I'm in touch with them regarding these issues too.
The last app (as of right now) that I am experiencing problems with is CSI: Crime Scene. The app doesn't allow me to connect to facebook to play with friends like I do when I'm on facebook.

Sprint Galaxy Nexus
4.2.1
Not rooted
I performed a factory reset on my phone yesterday due to it bogging down and being rather slow. I never did a reset after getting the 4.2.1 update so I figured it was a good time. I woke up this morning, putzed around the house, and setup Tasker again. I laid my phone down for ten minutes while I got ready for work. Whenever I tried to wake my phone and nothing happened. I tried a few more times and the screen would not wake up. I pulled the battery, hard reset, reinserted battery and the phone wouldn't turn on. Then, I wiped the contact terminals (on the battery and the phone) and reinserted the battery and the phone booted up. However, since then I have had some major problems.
1. Power button does not always work properly. I have to press it several times to sleep or wake the phone. (Okay, not major, just inconvenient and probably unrelated to the issues below)
2. No data connection whatsoever.
3. In the data usage menu, there is no longer a data toggle switch.
4. Under the Network Mode option, LTE/CDMA produces absolutely no cell signal whatsoever. I have to switch to CDMA only. (WiFi works fine)
5. Toggling airplane mode, as some have suggested, does not cause the phone to connect to mobile data. Another factory reset did not restore mobile data. Rebooting did not restore mobile data.
6. All of these problems are true before and after factory reset. No new problems were created and nothing was exacerbated as a result of performing a factory reset.
I've been from one end of the internet to another looking for solutions to this problem and I have found that many are having a similar issue but toggling airplane mode or rebooting fixes it. Not the case for me. Most also seem to be having this problem after rooting. Again, not the case for me.
Any suggestions? I would prefer to not return the phone. Purchased from Radioshack and the 30-day warranty has expired. This is my second gnex already, as the first one's charging port broke. It took over a week to get this one from another store which graciously shipped it in to my store. There's also the issue of being broke and not really being able to afford another $30 activation fee on top of the deductible for a new phone.
Why not try reflashing the stock image and updating again to 4.2.1?

Not at all. You'd use Odin . Myself I have very spotty sprint signal in my home. Spoke to a corporate executive and they mailed me an AirRave free . Never have less then full bars 3g all around home. You should a- flash to stock using Odin following posts in sprint sextjon . b - call up and try to get an airavana.

Excellent. I will give it a shot at some point today or tomorrow and then let you know how it worked out. Thanks!
So, I restored the phone to stock. Signal is still non-existent on LTE/CDMA mode. Cannot perform Profile or PRL updates. Still no mobile data. I'm guessing hardware failure?
Also, on setup it asks for a SIM card. And at the bottom of the drop-down menu, it says "No SIM card|Sprint" or "No SIM card|No Service" depending on if I am in CDMA or LTE/CDMA.
Also, in the Status menu:
My phone number
Unknown
MIN
Unknown
PRL Version
Unknown
ICCID
Unknown
Seems a little odd to me.
Attempted fully rooting and flashing radios. No luck there either. It's also not wanting to update. Tells me my phone is up-to-date (connected via WiFi). Downloading Cyanogen now to see if it will work in the morning.
And while attempting to flash a new ROM, got the famous "can't copy anything to the device ever, under any circumstances" error.
Update: Got CM10 installed. Still "No SIM" error, no 3G, no data, no LTE. Found some more information on this No SIM error. Apparently a few others have had this same problem and in the end had to get a new phone.
Anyone know anything?
You should a- flash to stock using Odin following posts in sprint sextjon
I've been back to stock twice now. The first thing I did was flash to stock. Then I played around a bit and now I'm back to stock again.
Is there a difference between using Odin and Nexus Root Toolkit to return to stock?
Bump
Wow, one day and my thread is buried!
After battling for about a day, I got updated to JB 4.2.1, I can do profile and PRL updates again, but there is still no 3G/mobile data, and I still have zero bars on LTE/CDMA and have to use just CDMA. I am currently stock but the bootloader is unlocked, no root.
If anyone has heard any solution, please help. Also, if there's a difference between flashing to stock with Odin vs NRT, please say so.

Try fastboot flashing your LTE and CDMA radios again. As far as I know, fastboot commands do NOT require root. I had a similar issue.
Edit: link to post with directions http://forum.xda-developers.com/showthread.php?p=39446679
Sent from my R2-D2 unit on the far side of the moon
Indeed, fastboot does not require root. I've flashed my radios several times now in various different ways. I even flashed different versions. I attempted again but with no luck. I have normal service when using CDMA but nothing on LTE/CDMA. Still no data, still "No SIM card" error.
Pretty sure I'll have to get it replaced. I've gone from stock JB back to stock ICS, rooted, CM10, back to stock ICS, rooted, back to stock JB unrooted, and flashed three different radios. I'm surprised I haven't managed to brick it yet.
UPDATE: Sprint is sending me a new phone, for free.
So I have been waiting patiently for the 4.3 update to roll out to me OTA with hopes that it would fix my issues but my phone has been saying download interrupted and so I have gone back to completely stock and triangle away to get my device status back to normal but it still wont let me download. When looking around for other possible causes I saw that my build number is JRO03L.I747UCDLK3 which comes up as a build number for a nexus 7, the correct build number for my att should be JRO03C. I have no idea how it got that way but I am wondering if the person who bricked it might have put the wrong version of the bootloader or some other part of the firmware on and it somehow didn't brick but is detecting a conflict and not letting me OTA. Or that is what is causing my cell network issues as well. Wanting input from a a few devs as I am not 100% sure what the first part of the build number represents.
Ok guys and girl, I am having a really weird issue with my Att Gs3 that I wanted to see if anyone could help with. To start off a little bit of background. I Hard bricked my s3 in August, sent it for tag and got it back working and stock with no issues. All I did was root the phone for fear of messing it up again but it was running all stock without problems for over a month since the unbrick. About 3 weeks ago I went out of town within the state but a ways away, I was talking on the phone with a co-worker right before leaving town. At some point that evening I get a a text from my wife asking why I was ignoring her calls, I had never received them and according to my phone was in the middle of prime 4g lte zone in San Antonio but I was apparently only receiving that lte signal and the phone was not switching to the voice network on 4g to make or receive calls, I was even able to voice chat with my wife but I couldn't just call her normally. After returning home I was still unable to make or receive calls unless it was right after a restart and I had to try about 15 times, so I called att and tried all of their bs which didn't make a difference at all. Looking around on the internet I found the number that you can put in to get into service mode and switched it to gsm or wcdma only and voila I could make calls again. The only problem with that being that I travel within a city for work and move from 4g to 3g to edge all the time but if I have it set for wcdma only then I have no signal and have to take the time to pull up service mode to switch back and forth. So I tried going back to completely stock again by resetting/ formatting all and flashing the stock rom via odin, my issue persisted so I also decided to flash synergy rom (which I was running prior to the hard brick) and then intergalactic because I saw the fewest problems with it to no avail. I have flashed each stock modem new and old which made no difference at all. Today I was messing around in service mode and found an area that was called handover, in that subsection you have the option for checking the phones ability to switch from gsm to wcdma and back as well as to hspa, when I select any of those options I get the message "temporary block due to build e" or " temporary block code".
I was wondering if anyone has any ideas about what the possible problem could be, imei, modem hardware, or a stubborn stuck modem firmware setting.
I was also wondering if anyone had any experience with figuring out how to re-enable handover because that is where I feel my problem is, either through adb or any programs that let me force change the settings, I would also be happy if someone knew how to turn of only LTE and have both gsm and wcdma on at the same time.
Any help would be much appreciated, I have tried everything I know how to do, but am to the point where I am forced to look at new hardware because my wife is pregnant and I really needs to be able to get a hold of me any time.

if that doesnt work go back to odin and install stock firmware 4.1.2 from Samsung but again you have to wipe data/factory reset

this is the software/programme i used to back-up, recover or even fix my EFS files (if they are corrupt and can be used) NV items reader writer
type it on google and pretty sure you will find something , try different links and again am sure you will find a download
have you tried flashing the new 4.3 stock firmware and modem follow this link for everything http://forum.xda-developers.com/showthread.php?t=2498233 or you can wait for AT&T to release the official 4.3 firmware and that will be 100% satified to be stable and will fix all your EFS/IMEI problems FOR GOOD :laugh:
i have the NV items reader writer software that can fix your problems but i dont know how i can share it with you without breaking any rules
ULTIMATE/final solution send it to MOBILETECHVIDEOS and will fix it like its nothing, take it to samsung and have to play some ball, or BUY A NEW PHONE
tried kernels (idont think it will make any difference) but its good to check
I have tried all the other versions but will try the 4.3 what's the name of that software so I can try and find it or of you have drop box you could pm me the info and get it to me that way . In the meantime I found an fusion 2 for 38 bucks from att so I can get calls for the time being.

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.
Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

This is something wierd with Kitkat. I do not believe a fix has been found just yet. but if you dial *#*#info#*#* on most phones you can get into the phone systems and turn LTE back on.

I didn't know about this menu. Thanks for that. I went into Phone Info and tried selecting LTE only but it didn't connect to anything. Not sure what that means. There are other
There are some other options in there for networks (e.g. TD-SCDMA, CDMA auto). Would any of them help picking up Sprint LTE?
Other options include:
Turn off radio, CellInfoListRate
Turn on IMS registration required
Turn on SMS over IMS
Turn on lte ram dump
SMSC:_____________ Update Refresh

KitKat roms are currently having data issues. You could try backing up your current KK rom and go back to Stock, update prl and backup your DNS settings then go back to your backed up KK rom and restore from the dns settings you backed up.
How does one downgrade from kitkat to jellybean? I tried to just flash a jellybean ROM with a clean install and got an error?

It says something to do with missing a partition?

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues?

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^
Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.

This should work http://forum.xda-developers.com/showthread.php?t=1794956
I've tried all sorts of roms, AOSP and Sense, they all stay connected to 4g for a few minutes at most after a reboot and then go back to 3g.
Everything else works fine, and my sim works good in other phones and stays on 4G.
Any idea what this could be or what is causing this?
Have you updated to the latest firmware? If your using kitkat roms, you need kitkat firmware. You can find the firmware in the second post of santods stock rom thread in development. Use the no boot.img one.

Yea I've flashed those also. Everything used to work fine until that roaming display issue. Never returned to normal for me, even tho roaming is gone.
Have you ever ruu'd back to stock and then done a factory reset from hboot? That is the only way to wipe out the network settings and force them to be updated. Worth a try i guess.

I guess that's my only option, thought maybe I'd be able to avoid it.
I'll try tomorrow and update.
Tried to ruu back to stock yesterday and still getting the same results. No 4g after a few minutes.

I'm not getting 4g at all on my phone. I came here to post a question and saw yours, so thought posting another thread would be pointless.
I've got NusenseSIX RC4.5 running and while the 4g icon comes on, there's no data transfer at all. I flashed the new firmware first, as instructed, and that seemed to go just fine according to the directions. But, when I swapped my sim card from my other One and waited a few minutes, even *228'ed, no data.
I got the phone already rooted and s-offed with TWRP 2.7.0.1. How do I get it back to stock to clear out the network settings? Or could it be a bad firmwware flash, so I'm screwed anyway?
EDIT: I redid everything, and just stuck with the Sense 5.5 mostly stock ROM. Data works now. Might've been firmware, might've been the ROM on my phone. Zero idea.
Is it possible to have a bad sim?
I just got a replacement device and I still cannot get 4G service for more than about 2 minutes before it switches to 3G

Sure, you can have a bad SIM, but I don't think that'd cause the drop in data transfer rate... lack of data all together, or other things not working, sure, but if you can actually catch a 4G link and then it drops to 3G, sounds more like the radios, the hardware, or just a bad coverage area. I'm no expert, though.
In case anyone was wondering, I ended up getting a new SIM and that has fixed my 4G issue. No idea what was wrong with the SIM, but anyway it sucked.
I'm having an issue with connectivity, please help if able.
1. used CF auto root method from this link https://forum.xda-developers.com/sp...uide-links-files-update-root-restore-t3366862 when I went to TWRP it would say recovery is not seandroid enforcing, but would go on to TWRP anyway.
2. made backups
3. connectivity problems started. could make and receive phone calls in certain places. dropped phone calls and went straight to roaming with unstable connection.
4. reflashed stock firmware from Koop1955's post
5. noticed I still had connectivity issues even when back to stock
6. reflashed twrp and root
7. still have connectivity issues
8. not able to activate through hands free activation or dialer codes.
9. can see sprint then it goes away. will get LTE in other places
10. Any ideas or direction to how I can start to affirmatively diagnose issues?
@Saafir, I have been trying to help, but I am out of ideas. Any suggestions for him?
Tried dialer code

I tried that dialer code on it, it goes to SCRTN then reboots and goes to Hands Free Activiation where it fails all times.
Thanks

Providing you have your MSL # do the ##data# menu, and make sure you have all of the LTE bands enabled. Carrier aggregation too. Other than that not sure what to recommend besides a trip to a Sprint store.

I have MSL code and looked at ##data#. All bands are enabled on the LTE front. Would placing a new SIM card work? or should I try going through more advanced diagnostics? The phone works and makes and recieves calls as long as i'm not in a bad spot. The thing is, there are ALOT more bad spots and it shoots me to roaming in the same area my fiancee has LTE and good reception. Same phone, same service. Any way this information can help?
One more thing

I had to get the phone repaired about a month ago. They placed a new daughter board completely on it. Could this affect it after flash? I had no problems with reception before root and twrp so I didnt think this would be relevant but maybe you guys know how to check if that is where this issue is coming from.

Doing a wipe via TWRP and then flashing the TAR should return the phone to stock state. Since the problem happens when you are unrooted and back to stock recovery (as well as when you are rooted and running TWRP) it seems likely that it is hardware. If I were you, I would do another wipe (System, Data and caches) then Odin the latest TAR and bring the phone back to where the repair was done. Tell them that you took the latest OTA update and the phone failed and that they need to fix it.
