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.

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.

Well, just moved to washingron, and t-mobile has no coverage within 10 miles of where I am at, but at&t has full 4g here. Got the at&t sim, on the go-phone plan, modified the apn and get data now. However, I keep getting warnings that my sim card is bad by several t-mobile functions. Can I flash an att rom to it, and do I need to avoid the att modems, or are they also ok to flash on the att network?

No. You can't do that.

First of all, don't flash any modems.
My phone is an AT&T Unlocked i747 Galaxy S3 and I no longer have AT&T service, but instead I chose Tmobile.
I now have a tmobile sim and have been flashing Tmobile roms ever since I changed my carrier to tmobile.
Everything works fine as long as I do NOT flash any Tmobile Modems.
None of the Tmobile or AT&T custom roms contain the modem image.
All of this also holds true when coming from Tmobile sim and going with AT&T sim.
If your phone is not unlocked I would suggest that you unlock it for best results.

What about kernels? Which T-Mobile ones can we flash onto an AT&T S3? I'm doing what you are. AT&T S3 on T-Mobile.

If you have a tmobile sim chip then flash tmobile kernel.
If you have a AT&T sim chip then flash AT&T kernel.
But if I were you I would stay with stock kernels which all the custom Jellybean 4.1.1 roms already come with.
So if you flash a Tmobile custom rom, it will come with a tmobile kernel.
If flashing a AT&T custom rom it will come with the stock AT&T kernel.
Good luck!

Awesome! I have a T-Mobile Sim in my ATT s3. I'm running universe s4 ROM. So I wouldn't have to flash a kernel when flashing TW ROMs from tmo?

You never have to flash a kernel regardless of which rom you flash.
All roms come with kernels, all the kernels you see here in XDA which are separate
downloads are custom kernels unless they are specified as being stock.
Custom kernels might be OK for experimenting for those people who want to
over clock or under volt their phones. In my opinion it's a waste of time and
cause more problems or issues than whatever advantages they may have.
(in my personal experience custom kernels have no real advantages at all)
tmobile phone att sim cut down

Hi all. I am new to all this and the more I read the more confused I become! I bought a T-Mobile T999 with a bad IMEI. I unlocked it and am using it with my Mobilicity SIM card.Everything is working fine except for the wifi hotspot. Also the T-Mobile bloatware is getting in the way. Iwas on my way to rooting the phone when i thought to myself... would it be possible to flash the Mobilicity stock firmware from the SamMobile sight onto the phone. If this doesn't work would I be able to flash the stock TMobile firmware back to the phone? So on the T999 can I flash the Mobilicity T999VVLDMF2_T999VYVLDMF2_MCT firmware from SamMobile
Thanks to any and all who might help.
No to all.

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?

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
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.
