Thanks for the info, can you possibly link me to instructions on how to flash just the rom and not the boot-loader or modem, all the instructions i see include both, and does it also flash the recovery or can i still hard reset at some point and go from S3Rx back to the stock android 4.1.1 currently on my phone. Thanks!

First I you must be rooted and have custom recovery like twrp. Then nandriod backup using twrp. Then if you are not on a newer modem for i747 I recommend downloading bootloader "mj2" and mjb modem if you have US version i747u. Install that modem and bootloader. You can find flashable zips in the i747 forum. This is not the latest locked bootloader. It is the one previous. You should be able to use the phone like this.

Then use option 1 of install method for s3rx. Download the rom and flash it and flash the rom and choose custom kernel mj2. I left the rom options in aroma almost all stock options. Be sure to nandroid backup before flashing the rom.

When I had my SG S3 ATT I747... I made a few roms, and 1 from tmobile and changed the setting in network mode to CDMA Only and was able to get 4g,

this was back in Feb 2013 if I remember correctly, that is when tmobile changed the antenna for LTE, before LTE was out in Tampa FL...

I actually had 402 downloads in 1 day, and never has anyone downloaded again, other developers made tmobile roms, so that is all you need to make it work, I was not able to change any modems back then on my SG S2 and S3, but using the tmobile roms I was able to change those setting which no other firmwares had that option..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] macklin345:
Hey so you had lte or 4g back then? I will give a T-Mobile rom a look see, my main thing is what changes in a tmo rom compared to stock att rom? Do you remember if you had a write up?

I'm going to search your thread for that tmo rom.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mdiaz33685:
now I didn't create thread, I just wrote it in some thread, look on my signature for that rom, I have a link to all my roms.., http://www.androidfilehost.com/?w=devices&uid=9390248398092763634 but there have been new firmwares since that, look for any tmobile rom any developer create, that would have that feature...

back then the LTE wasn't out yet, when they dropped the 4g antenna making way for the LTE..

I always said that was the smartest thing tmobile ever did... they forced anyone who was using tmobile frequency like simplemobile and tmobile users to buy tmobile phones...

forced me to buy 2 tmobile phones.. haha..

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Jinsoku:
I'm in a situation where I get zero signal at home and at work after moving, and I had flashed my i747 to work with TMO earlier this year. The best carrier around this area is now Verizon which is not an option for this phone, or ATT. I'm also not too knowledgeable on the bandwidth differences between networks and whatnot, so if I switch back to ATT, would I have to flash the phone back to ATT i747 stock? If so, how would I go about it? I ask only because I know it probably won't be as simple as just finding the stock rom and flashing back using ODIN. At least, I don't believe it would be, and this thread exploded last I came here. Also thread search doesn't work. D:

Any help would be awesome.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
No. You will need to add in your att apn for data but the att modem in your phone should still access all att frequencies. Even though you have a tmobile based rom. Just need the att sim. You could try it if you can borrow a coworkers sim.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Forge64:
What's the current method?

So I've just gotten an I747 from a friend, for use on T-Mobile. Got it unlocked, got a new SIM from T-Mo, and it's working with LTE/Edge only. Good enough, mostly.

I came across this thread and gave it a shot, nearly bricked my modem. Took all day to untangle myself and return to status quo pro ante. So with the newer 4.3 and 4.4.2 bootloaders, it's my understanding that this method no longer works. Flashing this modem onto a newer bootloader/firmware results in no bars, no IMEI, unknown baseband. Does anyone have other experience? Does anyone know of any methods for enabling AWS 1700 on newer firmwares, particularly the FNE4 4.4.2? Thanks. Have searched, keep turning up old info.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] androidphonz:

Yes, I would also like to know how to accomplish this on the new 4.3 and 4.4.2 bootloaders. Anyone have a solution? All the other methods do not work and result in soft and hard bricked modems.

Flashing an AOSP rom like CM will reset the radio firmware. You need a touchwiz based ROM.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Forge64:
Just wanted to check in, I overlooked some replies. Did this change last year, stayed on CM11 current up till Tuesday, when I flashed latest CM 12.1 onto my phone, and I'm still getting T-Mo LTE, have done so this entire time. Thanks yet again for this fantastic thread and resource.

forevergone - That's not my experience. Cyanogenmod generally does not include radio firmware, so it has preserved my mod since I started. Carrier OTAs would have replaced my baseband+radio, I'm sure, but CM does not, probably because they build for so many devices.

The last one will take really long to complete (minutes?). Once done, you should see something like:

+COPS:

...

If the above has WIND (302490)/T-Mobile (310260 not 31026) then you have AWS support.

As far as flashing an i747 in order to make it work on T-Mobile with 1700, I have seen it done with a few LTE phones being that the LTE bands inside the phone include 1700. When I took my Bell Galaxy Note, rooted it, and flashed the Skyrocket modem, I had access to WIND/Mobilicity's 3G networks which run on the 1700/2100 frequencies. Esentially I think that if we can edit the modem in order to make the 1700 band work as WCDMA instead of LTE, it should work. But I could be wrong.

I will attempt to play around with some modem files and see if I can get it to work. Ill post back here.

Yes, it has the software to do it, but the 8960 module used in the T999 is different.

The T999 for 1700 uses a MSM8260A.. HSPA+ is only on the 8260A, LTE is on the 8960

So we have three variants of Package-on-Package multi-chip modules.

8960/MSM8960

8960/MSM8260A

8960/MSM8270

They all have the same Krait CPU, same Adreno 225, same memory, use the same external WLAN/BT module, same audio codec chip... But the radio hardware is different with different inductors for the 1700 band.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] newuser134:
Not totally related, but on a similar subject, I came across this thread when looking for a similar answer about the wcdma bands of the Verizon GS3, the I535 model. "Out of the box" (when rooted, with the correct APN settings added) it can get HSPA+ on wcdma 2100 (most foreign gsm carriers use this band), it can also get gsm 850, 900, 1800 and 1900. I think that the hardware is there, but Verizon blocked it and allowed only 2100 MHz for the ability to roam on foreign carrier networks if you choose roaming through Verizon.

Other than the lte part, it's the exact same hardware as the AT&T I747, I have flashed an AT&T rom on it and it works fine (not radio, supposedly flashing AT&T radio on it will brick it). Despite being identical in hardware to I747, the AT&T model can get wcdma 1900, but the Verizon model can't. No one is certain if the physical hardware is there to get the 1900 band, but using service menu or netmonitor, the option for wcdma 1900 is there, but it won't activate, like it will 2100. All the gsm bands do work just fine, so if gsm 1900 works like on I747, it is strange that wcdma 1900 doesn't. I believe the hardware is there, but Verizon's modem firmware has disabled wcdma 1900 to prevent anyone from getting domestic high speed data on gsm carriers, basically on AT&T (or t-mobile in the future), but left 2100 alone so overseas roaming on foreign gsm/wcdma networks could still be possible. Just like you AT&T guys are trying to go from 1900 MHz to 1700, we on Verizon are trying to go from 2100 to 1900, same 200 MHz difference downward, lol, sorry for the joke. Anyone here know if it can somehow be verified if the radio hardware is there through terminal commands similar to those for checking AWS compatibility on the AT&T version? Does anyone think (or is willing to modify one) an AT&T modem image can be modified to unlock the 1900 band on the I535 without bricking it after flashing?

I don't know how you guys flash T999 radios on your phones without any permanent damage, but I've been told by some of the most experienced devs here that flashing another device's modem on an I535 will hard brick it, it will cause the bootloader to fail, so you basically lose the ability to boot into Odin or a custom recovery so you can flash your original modem back.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] joederp:
Did you look at stuff from samsung? Yes some of it is the same hardware. You can flash i747 because cpu, gpu, mem, wlan, usb, pmic are all the same.

But t999 has different radio hardware. Period. It has different /firmware aka modem partition. It has different name 8260A. Period.

So it is likely you will brick phone with wrong modem. Just like flashing s2 rom will brick it... so quit saying "same hardware".. it isn't
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] newuser134:
The I535 and I747 have the exact same hardware. I was comparing the Verizon and AT&T versions, maybe you should read my post before you reply.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] joederp:
Umm... no.. totally different pcb board layout. At least the t999 and i747 have 99% same pcb. They only have the same cpu, gpu, usb, pmic, audio, lpddr2

Radio chipsets are different, pcb different, passives and placement different...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] newuser134:
Oh ok. Sorry if I misunderstood you earlier. So you're saying the I747 and I535 have different radio chipsets? But they both have the name msm8960, which is the exact same. The T999 has the msm8260A, which is different from all other US variants of the GS3. So do you think it is possible that even with the same exact radio chipsets, the I747 can receive gsm 850, 900, 1800 and 1900, as well as wcdma 1900 and 2100, while the I535 can receive all the same gsm bands as I747, but only wcdma 2100? If both chipsets are the same, how could oe receive both 1900 and 2100, and the other only 2100? It seems like a software disabled function. That would seem like a lot of assle to go through (as in different pcb layout) just to disable wcdma 1900. Since the I535 has all gsm bands working, which it doesn't really need anyway, if gsm works on 1900, I don't see why wcdma wouldn't, the reception hardware is there, it's just a different type of modulation. That's why I think the I535 has both wcdma 1900 and 2100 MHz as well, but Verizon has disabled it through modem firmware and software.

The same as Note i717, and S2 LTE i727. Try to 'massage' the TMobile modems to get 1700Mhz working on S3 i747.
