So I bought this T999 unlocked originally and it was working fine with StraightTalk, I was working on trying to get LTE working but turns out LTE doesn't work with this model on other carriers other than T-Mobile I guess. As I was figuring that out I updated my baseband to the latest T999 baseband (UVUENC2) from UVMD5 and no longer can get a data connection to Straight Talk. I've tried downgrading the modem, checked IEMI, and nothing is working. Can someone tell me what I need to do? Does it need to be unlocked again or something? Maybe StraightTalk disabled my data? I don't get it. Please help!
Nevermind, Straight Talk turned off my data for some reason, OMG.
Just fyi, lte does not work on the T999, with any carrier. Its just not possible.

I have an unlocked Note 2 on Straight Talk AT&T. So I don't get LTE, and I want to turn it off. But AT&T RAT-locks their modems, so I can't. I know how to temporarily turn the RAT lock off, but all I can do is set the phone to only use HSPA+ (as in no EDGE either), and on top of that the menu option is missing for "Network Mode."
I've seen someone flash an i317M modem on a T889V succesfully (after trial and error and having to restore a QCN backup of their IMEI). What I'm asking is if I can flash an i317M modem on an i317. They're basically the same exact phone (unlike the T889/V, which is slightly different). Has anyone tried this? I just want to do this to be able to change frequencies whenever I want and turn off LTE. I hate that Samsung and AT&T locked us out of this menu. I know that all Canadian models (and the T-Mobile model here in the US) have the menu option.
TL;DR: Anyone try this?

I have the same issue.
I tried flashing the Rogers modem on my AT&T phone and it went into a boot loop.
Flashed the AT&T modem back and all was well.
What gives? If these phones have the same hardware.

Someone got an i317M modem on their T889V. They said they restored their QCN backup after flashing the modem, but it's impossible because the phone reboots like a minute after booting.

The person I'm talking about described it in a lot of detail and said in the end he has to stick to i317M modems otherwise the phone bootloops. In the i747 AT&T S3 section, someone provided a bootloader for the T-Mobile S3 (T999) and converted it to a T-Mobile S3 (with AWS) while retaining LTE.

So guys in a bit of a pickle here. I have a Rogers E-971 (sim unlocked) and I am trying to get data to work on Bell.
I have read the threads about the warning of LTE not working on Bell. So my questions are can I not get HSPA (3G) data working? I can live without LTE. ANy help would be appreciated.
Also I was quite familiar with Samsung S2 and S3`s and odin flashing. Can I not root and unlock the bootloader and then flash the Bell firmware to fix the data problem.....
Any help would be appreciated!!!!!!!! till I get this working, love the phone!!
Links to the best rooting and bootloader unlocking threads would also be appreciated...just got the phone today!! Still reading.
Is your apn correct?
If it is, then you just have to flash the Bell modem. Check one of Houston's thread. He has a link for the JB modems.
Bell has LTE on 2600mhz as well but very limited markets unlike Rogers.
You can flash the Bell or Telus modem for Band 4.

Thanks, so correct me if I am wrong, I should get data on HSPA? If not it could be the incorrect APN? I did try the APN a couple of times.
Thanks for your help, I got root now, just have to unlock the bootlaoder, then flash the modem when I find the threads. Mucho appreciated!!!
Okay I got it finally!!!! Elisha you were right, the APN was set right except for apn type, I had it as internet + mms, once I deleted that (which I saw on one forum) I now am getting data!!!
I have a i317 variant. My problem is I don't know if its considered Rogers or what. Carrier is Claro PR. I saw there was an update for the modem for the i317 so I flashed it. It said not for canadian carrier.. I'm in PR so I figured.. Now beanstalk 4.2.2 keeps bootlooping even after reflashed. I resourced to updating the modem because I wasnt getting any internet for some reason even after having the apn correctly.

Good Afternoon,
I currently have an unlock SGH-T999L with 4.1.2 and MD5 baseband. My current issue is that I get 4G once I put the ATT sim card but i dont get LTE. Does anyone have configuration modification to get LTE on a LTE Tmobile phone?
Looks like you have a T999 not T999L based on your baseband.. That device does not support lte so you will not pick up lte with it

My apologies I have the MB7 baseband which is the one for the T999L
Alright, on the apn make sure it reads fast.t-mobile.com, everything else should be fine how it is.. Should pick up lte after that
Edit: my mistake, you need the at&t lte APN make sure it is the correct one

I put the right settings and its proven that even if you put a Tmobile LTE phone on ATT network the most you will get is 4g
Any update on this? Just bought a T999L to use with my ATT Straight Talk SIM card, got it unlocked and HSDPA is working fine. Is not connecting to LTE though, unless I force it using *#*#4696#*#*. At that point, it shows LTE by the signal bar, but I have no data and it says "Emergency Calls Only". After a few seconds it goes back to H+ and everything works again.
I can't think of any technical reason why the phone won't work on AT&T's network, unless AT&T has blocked non-AT&T IMEI numbers?

Can you list your APN settings and results of a speed test? I just got this phone and I am only getting H+

wow sorry i took so long I just saw this... Its just the APN settings that the AlL things ATT says... http://forum.xda-developers.com/showthread.php?t=2616221 like post #4 I think... APN settings make sure you flash the newest modem for your service provider (modem will not change bootloader) and flash the ATT modules also..l. and Kernel depending on what phone you have and what service your using.... I now am on an S4 I337 ATT on ATT but was running a Tmobile app the Sickness , deadly venom, dark carnage.... they all work together.... just flash rom the kernel if needed and always flash modules for your baseband so if your supposed to be on NJ4 att kk 4.4.4 flash the NJ4 modules... and so on... sorry hope this helps
I recently just got a plan on the Canadian cell service provider, WIND, on my Roger's phone. I unlocked it and make it able to use AWS bands, which is what WIND is on. The phone read WIND fine when I was getting the plan, but only a few hours later the signal died and now I'm getting "Your SIM does not allow a connection to the network".
I tried using ODIN and flashing back to stock 4.1.1, but that has not worked. I don't know what to do right now.
I also tried turning the radio on and off, and that has not worked.
I'm stumped. Can anybody help?
You have to reapply the AWS mod the moment you flash another modem.
My phone was was modded and has had SEVERAL different modems and never had to re apply the mod is a hardware firmware flash and should stick. You could try I suppose but it may b with all the ownership changes with carriers here they may have changed frequencies. Like Telus screwed 90% of Public mobile customers.
When I modded mine I went through QPST there is a thread in development.
