Pre-requisites:
a) Rooted
b) CWM Installed
c) Sim Unlock Code
I could not find a straight forward way to get the ATT SGH-I727 Unlocked and working on T-mobile so I thought I'd make this short list of instructions for those going through the same trouble.
The first thing I had to do was unlock the phone. I contacted a local company that charged $35. Free options failed. Expect to pay. There were mentions of calling ATT for the unlock code which I did, however, the CSR looked up the IMEI and determined that the unlock code was not YET available. From what I gathered, because the original phone owner was still under the two year agreement, this unlock was on hold until that time period was up. Those that bought their phone outright without a contract are provided their code with a call to customer service.
With the phone unlocked, I still couldn't get the phone to connect to a T-mobile signal. With a tmob sim, either a no-signal icon appeared or the phone simply showed full ATT bars but wouldn't allow T-mobile use in options. Also, *#simunlock# would generate a com.android error.
Finally, the following formula allowed for an unlocked phone picking up T-mobile signal:
1. Install the STOCK ICS UCLF6 4.0.4 - UNTOUCHED - rom following the instructions on that page impeccably.
2. Install Busybox (may not be necessary)
3. Install UCLF6 modified boot Kernel
4. Install T-mobile compatible radio - Blaze_4G_LB7_ICS_Radio_MOD worked for me
Boot it and see if you have a signal. You may need to go to options and manually choose T-mobile.
After that, I was able to install a different ROM. I chose SKY-ICS 4.2F6-2.6.1
With any new rom, you will still need to flash a tmob supported radio.
My s.o. will be using this phone, so I won't be messing with other roms, unfortunately. Let me know if you have a fast and stable configuration.
I hope this helps.
Actually as the radio is deeper than the firmware we flash normally you should only need to flash a tmo radio once unless a rom has radio built in most all roms do not

Does it make a difference whether I install the stock ics and kernel you provided? All I did is update the phone to ics via kies, install a recovery, flash superuser, then installed the blaze 4g radio. Would it make a difference between doing what you said and what I did?

It works, but its very crappy, sometimes connects, sometimes doesn't, even followed this post's instructions, still has crappy connection
For those who have T mobile fine on the Skyrocket , how much DL and UP speeds are you getting (and compaired to true T mobile phones data speeds) ? I heard some say they never get more than ~1 or 2 mbps which sucks TBH
Heard this is the hot T-Mobile skyrocket radio.

Are you trying to get Call/Text connection or 4G HSPA+ Connect?
Works on WIND too!
I spend a while trying to get this phone working on Wind (Canada's 1700 AWS carrier, similar to Mobilicity / TMo). I've finally succeeded by doing the following.
1: Install latest ICS STOCK
2: Use CWS to flash AT&T UCLF6
I have not been able to get nearfield working with this modem, but it's working great other than that (albeit somewhat slow UL/DL speeds, but that's likely a more wind's crappy network than the phone). Let me know if anyone has any ideas regarding the Nearfield issue.
Just wanted to share. I have been made so freaking happy by the fact that this worked
I bought my SR for full price (549.99) months ago and stupid att also saying my unlock code is not available yet !!
I made the mistake of not meeting at the Verizon store and bought a Galaxy S3 off Craigslist. It has a clean esn but it won't read the 4G sim card. I found out it was flashed to Cricket so I used Odin to flash it back to the original rom that came with the version of the phone which changed it to Baseband version: I535VRLEC but this still won't work it still has the same problem reading the Verizon 4G Sim.
I guess my question is... if there is a different rom I should flash it too? Or is it that once it has been flashed from Verizon to Cricket it can't flashed back to be used on Verizon again?
I would just get a new sim card from Verizon, that may resolve your issues. A few questions:
1) Does it still make calls and texts? The main issue is it doesn't connect to LTE? Maybe I'm not understanding your issue entirely.
2) Does the phone have your phone number and matching IMEI (labeled on the retail box) listed in Settings/About Phone?
You could Odin the stock image VRALF2, VRALEC was a pre-release image. Do not accept the OTA then dial *2767*3855# to reprovision the sim card. Maybe see if this resolves your issues.

Well when I brought the phone in the first time to get it activated I was switching from a Droid X so they gave me a new 4G Sim card. But yeah it won't make calls or texts and it won't connect to there 4G data network or pick up the sim.
So are you saying changing it from VRALEC to VRALF2 might fix it?

Oh yeah and I don't have the box it came in but my phone number did show up in the Settings/About Phone
And at the store they told me it was picking up the Verizon network it just wasn't connecting I guess? so it wouldn't get on the internet or make calls or texts

What I was saying is that normally people Odin to VRALF2 or VRALG1 then reprovision their sim card. That code will work on VRALEC but I was just trying to put you on a common starting point since we here don't really use the VRALEC stock tar in Odin. Primarily what you'll find in the stickies are VRALF2 and newer images. VRALF2 was the "store bought" earliest software version of the Verizon GSIII from the summer. Its worth a try but consider the following first.
Since you said it doesn't call/text then I think you lost your IMEI. Could you check for me under Settings/About Phone? It should be 15 random numerical digits if I'm not mistaken. If its not 15 digits, it will be 0 or several 0's. Don't post the exact number if it is 15 digits, but tell me what you see.

No I didn't lose the IMEI it's still there, all 15 digits.
So is it possible to flash a Galaxy S3 from Verizon to Cricket. Then back to Verizon? Is it just a matter of changing to the right software?

Honestly I know nothing about flashing to another carrier. It's not something that I have a reason to research so I'm not knowledgeable in that area. My suggestion still is to run that reprovision code since you've already Odin flashed to VRALEC.
EDIT: To clarify, my suggestion is Odin VRALF2 then run the dialer code.
Just as a precaution, you should write down your IMEI, ERI, and maybe even your MIN and PRL version and store them somewhere on your computer. Since you don't actually have the retail box, this should be kept safe if we can't get this current situation straightened out. My reasoning is if you do somehow lose these before you're 100% fixed, having them written down may help you if you need to use one of the IMEI or ERI tools in the dev section.

Ahh, great! When you do just make sure to root, unlock your bootloader, make a nandroid backup in CWM or TWRP recovery, then use the "Comprehensive IMEI /EFS Backup" thread to properly backup your IMEI.
I encourage you to flash roms until you find something you like. I'll suggest that you stay with touchwiz roms then see whether sticking with Samsung's software in its various forms is good enough for you. If not, there's plenty of AOSP to go around!
So you just followed step 5 on the link above and it worked? (flashing with 4.0.4 ROM)
I'm going through a similar issue and been having a hell of a time getting mine to work. Mine was flashed to work on nTelos which is a CDMA provider in my area. I have flashed to just about everything possible (except 4.0.4) and haven't had any luck.
I went to the Verizon store and they tried to activate the phone but they couldn't but game me a sim to use and told me to call back if and when I could get it flashed back.
I tried at one point to take a working sim from another phone but it will not activate..... will not make calls, will not get data etc etc. when I dial 611 it still goes to ntelos.
Someone suggested putting Phone info on and setting the Phone to RUIM but I could not find that setting in Phone Info (even on the correct phone info, after time I found out the original phone info was pulled from the play store and I had to manually download it.
Anyway with the SIM I have and following section 5 as suggested mine does not give the option to accept or deny the OTA so I can try to enter the re-provision code. Should I get hold of the known working SIM to attempt this?
THANK YOU SO MUCH!!
The key to this however is to have a working SIM (the only one in our workplace was from an iPhone 5), I fashioned a nano SIM to mini SIM adapter and got the info on to the phone then my phone could finally be activated however the nano SIM I used got tied to my phone and couldn't be put back to the iPhone 5 it came from lmao... so I had to run to the Verizon store to get my co-workers phone re-activated.
But going down to the 4.0.4 and VRLEC modem then inserting the active sim, reprovision once it activates (it didnt give me the option to not allow it to do anything), then insert the mini sim, call Verizon they got it activated, I just now updated back to 4.1.1 (need to get 4.1.2) and everything is working wonderfully!!
All of this info is extremely refreshing to hear since I have the same problem with one exception. My s3 has a bad charger port. Sent it in for warranty repair and Samsung said it was moisture damaged and corroded and is not covered under warranty (lies). But that is beside the point and another subject.
My question is, can all of this stuff be done through the sd card and not through the USB? I know it is a long shot but any help would be greatly appreciated.
Thanks!
I know this thread is a little old but I just wanted to say thanks, the exact same thing happened to me (phone was previously flashed to cricket but i was unaware until AFTER purchasing and trying to activate)
ODIN Flashing the OMBINATION_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship.tar.zip package then reprovisioning with the *2767*3855# worked like a charm, I was sweating for a while as the deal was from craigslist
So far as i can tell to do this you NEED to use the VRAL as I tried a few other (newer) stock files and this was the only one that worked
THANKS AGAIN!

My Girlfriend bought me the new Verizon Samsung S4....not knowing that each phone is "tailored" for the carrier. She used her upgrade for me for Xmas and instead of telling her "i cant use it" and have her feel bad, i would like to Flash a T-Mobile Stock Rom onto the S4.
I currently have my T-Mobile Sim card in the S4, and it actually does work for Voice Calls, but Data wont work. Ive tried configuring several different APNs to it (per T-mobile's website). But i still just cant get Data. I also can not get "wifi calling" because Verizon's Rom does not offer it.
So quick questions:
-Do I need to have Root in order to Flash my Verizon S4, with a T-Mobile Rom. I am assuming Yes.
-Would any T-Mobile, Stock Rom, that works with android 4.2.2 be compatible?
IS IT AS EASY as i am hoping? I am not shy to the Rooting/Unlocking world, so if its possible, i will get it done.
Here is your fix

Carrier unlocking is separate from ROM. If you can install custom recovery (CWM, TWRP), switching from ROM to ROM is as simple as doing a backup of one, wiping the device, and installing another ROM. Always save a back-up to your computer, and it's also a good idea (much easier in the end) to do a batch back-up through Titanium of all the user apps, so you can simply restore them to the new ROM instead of downloading them all over again and losing the app data.
Factory firmware can be obtained from sammmobile.com and are flashable with Odin (google it).
thanks for the help but why can't she update the stock rom from the settings though when she switched to tmobile? are the update locked to the att carrier?

I'm working on this too. So far I've got the same situation as you, Data works but no calls/text.
in a few weeks the person who wants me to unlock this phone for them is switching carriers and plans on buying a new phone to use until I can unlock the S6, so I'll have more time to mess with it then.
There's a few things I want to try, but I can't post links here (XDA rules).
One involves Rooting and using a service code to unlock the bands (google "TeamUSCellular GSM unlock S6")
The other also requires rooting and involves using "galaxy tools" to unlock the bands (not sure if this app works with marshmallow, though) (google "theandroidsoul how to sim unlock sprint galaxy S6")
My hopes are not high for getting this phone to work fully. I've also been trying to get custom ROMs to work, but I can't get the cell radio to work at all on custom ROMs. Even with the stock SM-G920R7 Kernel straight from the latest update .tar

I'm working on this too. So far I've got the same situation as you, Data works but no calls/text.

Thanks for the suggestion, yeah I have tried galaxy tools (GT) to change the phone mode to LTE/GSM auto and tried different CSC values, and accessed the hidden menus through there. The sim unlock in GT asks for a code which I dont know, but the phone doesn't seem to be locked anyway since it doesn't care when I try different sim cards. Weird thing is the GT app doesn't work very well (most hidden menus not working) on the current rom i'm using but worked better on the stock cspire rom. Note, I tried using MSL 000000 in ##3282# data menu and it works but most the settings in there don't seem to be applicable to GSM networks.
Currently I'VE been messing with the build.prop file, also tried the CDMA to GSM flashable zip which edits the build.prop but nothing has gotten better. One time after editing the build.prop the phone would only turn on with a blank screen and vibrate every few seconds, that was SCARY. Also was planning on flashing other radio/modem but having trouble finding many of those files and pulling them from roms seems difficult to get the correct file to flash on odin.

I'm not sure you'll even be able to flash other models' modem..? I can't say I've ever tried.
Anyway, getting your hands on the firmware is easy. Just use SamFirm (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647)
To use it, just input the model number (SM-G920R7/R4/P/V/T/A) and the region code, then select "auto".
Region codes and model numbers:
C-Spire: ACG (SM-G920R7)
US-Cellular: USC (SM-G920R4)
Sprint: SPR (SM-G920P)
Verizon: VZW (Locked out from download, app can't download) (SM-G920V)
T-mobile: TMB (SM-G920T)
ATT: ATT (Locked out from download, app can't download) (SM-G920A)
This app downloads firmwares directly from Samsung servers, so the download is really fast and guaranteed to be perfect/stock.
**the SM-G920R7 is closest related to the SM-G920R4 (US Cellular) & SM-G920P (Sprint). The US Cellular one recently supports GSM Bands natively without any rooting/messing with hidden settings, so that's where i'd start. You may not even need the baseband/modem, just flash the rom? I'm not sure. Good luck dude It'd be awesome if you get it working
*** Also, make sure you have a backup of your EFS before messing with the modem. Apparently if you flash an incompatible modem you can erase/corrupt the EFS partition and lose your IMEI. Hell, make a FULL backup with TWRP, and make sure that backup is copied over to your computer before doing any flashing. You can't be too careful with this.
Haven't had any luck flashing stock firmware or modems from other models using Odin, errors with a security message or something, tried G920A and G920R4. Probably for the best I suppose. Flashing custom roms has not been a problem, even if the don't work properly. Wonder if there is a test mode or way to use logcat to see why calls don't proceed like normal. Never worked on going CDMA to GSM before, I always did CDMA to CDMA in the past.
