Is there currently a working T-Mobile modem that gets 3G on T-Mobile for the AT&T note 2? Instead of the typical Edge. (same as on Note 1) I have my AT&T Note 1 with 3G on T-Mobile... Any releases yet for the Note 2? I already ordered the dual sim card adapter for the Note 2...

I can't seem to get a straight answer on this either. I have been searching for 2 days now and I haven't been able to find any solutions. I have jediX on my unlocked AT&T phone with a T-Mobile sim and all I get is Edge. ive tried to put on the T-Mobile Radio and it just boot loops me.
I may have to try and find someone that wants to trade phones with me at this point.
I believe that most of the T889 roms have a radio built in.. Have you tried that?

yes i have, when i flash other roms that say the radio is included, it still shows the AT&T radio under settings>device info.
I have Jedi -X4 for Build number but,
i317UCALJ2 listed as the Baseband Version.
Model number shows SGH-T889.
if i try to flash a the T-mobile Radio, it just boot loops.

I have only just started looking into this myself and was expecting a working T-mobile radio that can be used on AT&T (or Rogers) to be floating around, considering they are all using hardware revision JRO03C.
Any help would be appreciated.

Please clarify: you have a T889 (TMo N2) device using an AT&T SIM, in an area confirmed to have AT&T LTE service, and you're getting no LTE? Have you tried flashing the modem package off an i317 (AT&T N2) onto your device to see if LTE gets activated that way?
Did you tried *#2263# and then u can choose lte 17 for att.good look ..
I didn't try those two, but I will right now. Tried another method using a long input string, but it didn't work.
Yep the *#*#4636#*#*doesnt work on theese roms, however the*#2263# works on the x5 rom but not on the 4.1.2 lk7 roms.on theese roms u can choose lte and hspa from mobile settings but there is not lte only option.do u have a succes with the code ,by the way you can try hspa plus on 1900 mhz on tmobile card with that code too.i tryed it and I can confirm it is 21mbits for now.

TMobile Modem on Galaxy Note 2 ATT i317
I am in the same situation as the OP. Looking to flash a T889 modem onto an ATT Galaxy Note 2 (i317) similar to the solution for Galaxy Note 1 ATT (i717) users using Tmobile network (by flashing a modified Amaze? modem).
Anyone successful in getting 3g TMobile speeds with their Galaxy Note I317?

LTE should work if you do that, but make sure your IMEI is still OK, and have a backup phone if you try flashing back the T889 modem. My phone is stuck in a bootloop since trying to go T889V -> I317M -> T889V.

I have an AT&T note 2 unlocked working a T-Mobile sim and 4G has been working from the start!
Did you double check that you're in a strictly AWS area, spectrum-wise?
Oh, and quick update: I was able to get the phone to boot with the I317M modem, switch it to diagnostic mode and fix the EFS NV entries. LTE works, not sure about AWS HSPA and not in a position to test.

So you have a T889 and flashed I317M Modem and accessed the *#197328640# code and did what exactly? and you are getting LTE on AT&T?
please elaborate.... please...

Hello TEKHD,
I have a T889V, but my carrier up here is Virgin Mobile Canada, whose network is technically closer to AT&T's band-wise. DC-HSPA 42 on 850 and 1900 MHz with LTE on Band 4 (AWS).
Reason I got a T889V is because I also keep a T-Mobile SIM for stateside trips, it was a bit cheaper and it leaves the door open to switching to Videotron in addition to the "Big Three".
I first unlocked the phone using the ServiceMode menu method.
I backed up /efs, and this is where I made my first mistake. I know I've been ranting about this for a few days now, you need a proper Qualcomm NV backup.
I usually stick to the Canadian ROMs as they tend to remain closer to their international brethren than the US ones, and also because they don't require tethering fixes. In this case, the T889V ROM also allows switching network modes between GSM, WCDMA and GSM/WCDMA/LTE easily.
I did modify the CSC files to remove the <CscFeature_Setting_DisableNetworkMode>lte</CscFeature_Setting_DisableNetworkMode> line in /system/csc/others.xml and even went so far as making a customized VMC CSC and reapplied that to get all the other little carrier tweaks like FastDormancy. The line is cosmetic only, as I've had it show 4G in the network icon and still get LTE, otherwise it shows 3G, H, H+ and LTE on the T889V. The other place I've seen it have an effect is in the network settings where it'll show GSM/WCDMA/LTE instead of GSM/WCDMA.
I've used Odin before, I have a download jig (two paralleled leftover 620kOhm resistors and a Sparkfun breakout board) and I've tarred my own images before with Cygwin.
To get the necessary files, I downloaded the stock T889V, I317M (Canadian LTE Note II variant, the one that'd actually be sold by VMC if they ever do.) and T889 ROMs from Sammobile.
My initial attempt to flash the I317M modem through Odin (as a standalone image) gave a fail before the phone began the actual writing process, i. e. it transferred the radio image without any issues. Later experiments show that only the T889V modem tar flashes with Odin, the T889 one doesn't either. Same goes for the whole, original Sammobile images, the modem partitions fail if you're cross-flashing.
I then used CWM with an update zip sourced here on XDA that included a "flash_image" binary to flash the 317M LJ2 modem. I used it to prep T889 and 889V zips as well. Rebooted the phone, it connected and gave me LTE, network icon and all. The before and after speedtests went from 3.5 to 35 Mbps. I did check and my IMEI showed 0 instead of, well, my IMEI.
No big deal, or so I thought, I'll just restore /efs in CWM, reflash the T889V modem and carry on. NOT.
The phone immediately started bootlooping, and the only way I initially got it to stop was to flash an N7100 boot.img. The S-Pen didn't work, nor did any networking apart from wifi. Getting QPST to talk to the phone was a bust as well; the hen and the egg.
I tried different combinations and couldn't fix the problem. (My flash counter sits well over 20 now.)
I got another poster (deeznutz1977) to send me his T889 NV backup (sans IMEI) the other day. I later had the idea of reflashing the I317M modem again, which did not boot loop after all (there may have been a matter of wiping /cache and Dalvik cache at the right time).
This time dialcode *#7284#, selecting "Qualcomm USB Settings" then selecting "RNDIS + DM + MODEM" worked. I could get the programs talking with the phone. I inserted my IMEI in deeznutz1977's backup, wrote that to the phone and rebooted.
The phone doesn't bootloop anymore, my IMEI is back, as is service on my current carrier. Plus, this configuration still works with AWS HSPA. The one catch is that bootloops resume if I reflash the T889V modem through either CWM or Odin.
I made a few more speed tests before writing this and managed to get an average 45 Mbps down and 12 up along with a 40 ms ping.
Hope that answered a few of your questions.
Regards,
Darkshado

Wow... thank you for taking your time and explaining everything... really, thank you... so you managed to completely transform your T889V into a I317M... that's why it now bootloops if flashing the original T889V... as it would if you really had an I317M... is that right?
you don't have access to a sim with the t-mobile band in order to test for just a minute?
So... here is my story... maybe I can help here with the transformation of T889 to I317 and viceversa... (or maybe an hybrid modem like the one for the Note 1)
-> I have both the AT&T I317 and the T-Mobile T889...
-> I also have both with dual sim card adapters...
-> I also have 1 Unlimited everything T-Mobile sim card & 2 AT&T unlimited everything sim cards...
I want to be able to keep the T889 with 1 sim -> working LTE on AT&T and the 2nd sim -> ready for future T-Mobile LTE...both sims in the dual sim card adapter on the same phone of course (I also want to sell the I317) just keep one universal LTE Note 2
What can I do here? Willing to sacrifice whatever I need to... in order to accomplish my objective... This will help everyone here on both carriers...
As for now... I have noted that while navigating on both phones thru the service menu... the I317 says ENS: ENABLED and the T889 says ENS: DISABLED ... searched on google... no answer.... ENS stands for? Emergency Notification System? lol
Is there anything I can do here since I own both phones... that can sort things out in order to unlock the LTE feature on the Tmobile variant? or is that something we all just have to wait for the carrier to do via OTA? Is there any modded modem that can solve this? Your I317M modem... can it do something here for the T889?
On the pictures the one on the left is the I317 and on the right the T889... both with AT&T sims at the moment of the picture. If I go outside, the AT&T Note 2 will get 4G icon (LTE) and the T-Mobile Note 2 will stay in HSPA+...
I have MTP + ADB on both phones when using code *#7284# also... is there anything useful in this code besides unlocking phone? *#197328640# ??? Diagnostic mode here... *#0*# any more codes?
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?
Bump
*bump*
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.

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

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?

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
