[Q] D2ATT and CM 10.2 Loses mobile data

So I flashed CM 10.2 to my D2ATT last friday and was completely happy with it. The snow storms cancelled my weekend plans so I was home with my wifi all weekend. Upon leaving for work this morning, however, I noticed that I was unable to pick up mobile data. I found out through googling that this is a common error with 10.2 so I tried upgrading to a CM11 nightly. For whatever reason my phone doesn't like them and CWM gives an error when trying to install them even if I perform a system wipe.
I tried switching to AOKP and got absolutely 0 service from AT&T as far as cell reception, calls, texts, and mobile data.
I'm back to CM 10.2 right now, and word on the net is that I need a modem file, but I can't seem to find one for my phone. Can anyone get me a link or a fix?
Thanks!

In the SGS III development section there is all the modem files it has it's own thread

I appreciate the response, but I quite frankly have no idea what I'm looking at in any of the three dev forums and can't find the modem file thread. Could you please be a bit more specific?

before trusting on anything
go to your setting-->about and look if your IMEI is still intact

I do have a 15 digit IMEI as well as a two digit IMEI SV. I did however notice that it said "mobile network status: disconnected" so I had it search for networks (it found two labeled AT&T and one was a 5 digit number) and auto select the best one. During that process I received and sent a few texts. After that process it said "selected network" but nothing had changed, and it still said I was disconnected.

I had the same problem when I flashed to stock 4.3, I lost T-Mobile service and only could call and text no data! I flashed the modem from here http://forum.xda-developers.com/showpost.php?p=47817339&postcount=23 only download the modem_ and after I flashed and reboot viola! Data working perfectly Hope this helped!!!

T999L issues

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.

No Mobile Data

Ok here is my story. I decided to downgrade my Note 2 I-317 back to 4.1.1 due to wifi issues I was having on 4.3
all was well once I got back to 4.1.1 so I decided to unlock my phone ( For some stupid reason) everything seemed fine the whole night so I thought. The next morning I woke up to not having a mobile connection then I remembered I forgot to pay my Net10 bill. So after reactivating the 3 phones I have the Mobile connection for the 2 other phones worked fine but mine didn't. Not knowing I decided to reupdate my phone again thinking I might have done something wrong trying to unlock it. then I bricked my phone not knowing about the bootloader issue I finaly figured out how to fix that issue but once I got back to 4.1.2 I still have no frigging data.
I need help here what have I done wrong and any insight on how I might fix this problem.............Thx in advance

Try Odin flashing the tz-param file in post #2 here.
http://forum.xda-developers.com/showthread.php?t=2618447

ok I tried that and it still aint working I really think I messed this thing up when I tried to unlock it when I was on 4.1.1 I think I hit the sha256on instead of off

no matter what apn settings I use will not get me my 4g symbol. I can txt and talk just no data

I really think I turned off my radio or something idk very frustrated

1. Check with Net10 on the off chance they need to reprovision your phone/sim
2. Your APNs should be fine if they were working before, but here's a list of a few options to try jik ... http://androidforums.com/net10/676048-net10-byop-apn-settings.html
3. You could try flashing just the 4.1.1 lj2 modem and try the unlock again .. This might clear your issue if you did choose the wrong option since the unlock involves turning that setting off - uncharted waters here, though. If you do attempt this I recommend you make a efs backup first.

Not registerd on network

Hi guys
You are probably sick of hearing this problem but I have had it and I have tried to scour the internet and I cannot find a solution to my problem.
Basically I have not used my Samsung Galaxy note 2 GT-N7100 for 6 months or so and I decided to use it and to use a new rom. Now after I installed it I could not call anyone or text anyone nor could anyone else call me or text me. However, the internet was working which was strange but again I got the same error message "not registered on network. I tried to install another rom in the hope that the problem would be sorted out but this time I cannot get the mobile data or the wifi to work either. The main problem is the "not registered to network.
The first rom I installed was the latest Hawkish extreme rom and the second one was Android Revolution HD by Mike1986 if it makes it easier to help me. I will still be searching on the internet but if someone can help me that would be grateful and much appreciated.
Thanks in advance

Try the following: use Root Explorer enter to EFS folder, delete NV_DATA.BIN and NV_DATA.BIN.MD5. Reboot your device and check imei.

Thanks for the reply.
Right before bothering to read the reply I decided to download omega jellybean 4.3 and guess what, no imei number but I flashedkit kat back in and it was buisness as usual. emergency calls only. Right when I get back home I shall try what you told me, but one question as a n00n and I do apolagise, where is this efs folder?
Thanks for the reply, I almost lost my rag yesterday with this phone!
Thanks

Root/efs.

I have a similar problem. The 7100 was purchased with Wanam lite 4.1 installed and working well with TMO SIM card. I upgraded to stock 4.3 JB and will not connect to network. Build is XXUEMK9. After factory reset,it starts up in Greek. Any ideas? Thanks in advance.

Sprint Note II on Straight Talk CM11

Ok I just flashed my phone to CyanogenModd 11 and now I've lost data. I've read a bit about updating the APNs but I'm not sure what all I need to put in. I flashed to CM11 to use the hotspot since on the stock rooted ROM I kept getting the Sprint Device Self Service screen asking to get a hotspot plan but nothing was available. All the apps (FoxFi, Wifi Tether For Root Users, etc.) never worked please help.
Edit: I DO have texting and calling

You need to edit your build.prop first. There are a couple of lines that have change. See attached pic.
