I'm sure this has been asked before but I can't find it. Here in our at&t forums, we use a Tmo Jelly Bean leak that has been modified for our phones. Over in the Tmo forum, they have the same leak with better battery life and stuff. My question is, will the Tmo ROM run on our phones as is? Or does it require special mods? I know an at&t modem is required, but what about the kernel and so forth? Forgive my ignorance.

Wondering if I moved to AT&T will I be able to flash a skyrocket rom and there modems to use the AT&T basebands? Would I be able to use there 3G and 4G?
bump: Sorry if this is a stupid question but I really don't know. Any info would be awesome.
Sorry if this sounds like a really nooby question.. My girlfriend has a SGSII on Telus, that I rooted a long time ago, but now I'm wondering what roms to put on her phone. Do I have to use a rom specifically for telus? or can any t-mobile rom work? Do I need to flash a new radio or modem?
I have a Telus Note, and I can use any ATT rom available, just wondering if it works the same way for these phones.
Thanks for your help!
You can use any T989 ROM. Not sure if Wi-Fi calling will work on it. Here is a link from a great dev that made a nice ROM based on your ICS update. I've only heard good things about it.

Awesome, thanks for your help!
As the title states, I just picked up a AT&T galaxy S3. I am looking to use it on T-Mobile. Coming from a galaxy S1, the unlocking procedure is a bit different. It also seems that roms are fairly brand specific, so I assume I should be looking for i747 roms. There are so many options out there, could anyone point me in the right direction to get this phone up and running? Are there any special considerations I should be taking since I am using an AT&T phone on T-Mobile?

Before you do anything, if you want to unlock you phone so you can use it on another network go to this thread http://forum.xda-developers.com/showthread.php?t=2033225&highlight=sim+unlock
You will probably need to change the apn numbers to match t-mobile which is easy.... as far as roms go, you should do some searching for t-moible roms in the development thread. Also not being familiar with AT&T and T-mobile you should check to see if they use the same band and also check which modem (radio) you need... I am sure there have been lots of people that have done this arleady.... search search search at least you asked the question before you started not after you had a wreck
Thanks for the link. I did the unlock procedure, haven't tested it yet since I still need to cut down my SIM card.
I also went through and did the CF-Root procedure with ODIN. So theoretically the phone should be ready to flash a custom rom.
I was under the impression that I should be looking at i747 roms instead of the T-mobile version (i999?) since my device is originally AT&T branded. You are saying this is not the case? Basically I should look at roms in the T-Mobile section? It might not matter anyway since some popular roms run on both.
UPDATE:
I installed Stockorama V2 on the phone and it is up and running on t-mobile. It is a multi-carrier rom, but I used the AT&T options when installing. Would I have better luck installing it as T-Mobile? Basically, can I install a T999 rom/kernel on a i747?

yes sir, just the modem is different
Hey guys, I have been having more than normal dropped calls and poor signals so I have decided to move to an actual TMobile ROM.
I am coming from an AT&T based SKy Note Air G2 ROM with the MK7 modem and PSN_AGNi_pureSTOCK-v3.9.5_N7105_4.3_AROMA-signed Kernel, I also had to do a WIFI patch because I upgraded from the 4.1.2 BL to avoid Knox issues. I have TWRP back from March this year. I was wondering if I need to do anything special before installing the JEDI ROM.
Any helpful guides to install this ROM? I have checked the ROM page but couldn't get the info I want.
Can changing back to a ROM native to your carrier help with service signal?
I have a pristine looking insurance replaced Note II that I'd like to Root and Rom with a stable Rom that retains T-Mobil's WiFi Calling feature.
Also, I'm getting the unlock code for the device sent to me by T-Mobile; which I'd like to do as well. I do have a T-Mobile SIM for it and can get at an AT&T SIM to unlock it if necessary.
As far as Root/Rom goes; I'm fairly certain this limits me to Android 4.3 and below; since T-Mo hung Note II users out to dry for a factory 4.4.x update; and I need the WiFi calling feature to work properly.
This specific device showed up with the following on it and is currently locked.
Firmware: 4.1.2
Baseband: T889UVBMD1
Kernel 3.0.31-935627
Build No: JZ05K.T889UVBMD1 (probably redundant info)
I have 2 Questions to start:
1. Should I unlock this before or after flashing root/ROM?
2. What Root/Rom(s) is (are) stable and let's the T-Mobile WiFi calling feature working properly. (I've seen Info on Jedi Rom, not sure which of them would be best or if there are others that keep WiFi Calling)
Some advice on this would be sincerely appreciated; since I have no experience with unlocking and/or root/ROMs; though I've been reading and really can't find info on my first question.
TIA to anyone that can point me in the right direction.

1) If you are getting the unlock code from T-mobile then it does not matter if you unlock before or after you root your phone.
2) I would advise to read through the forums in dev section and decide for yourself which ROM better suits your needs. Only Stock based TW ROMS retain/support WiFi calling and those are the ones to look out for. A quick glance for feature list under OP should let you know if WiFi calling is supported.

Thank you very much ciphercodes.
Yeah its a tmo unlock code, so one less thing my noobishness to worry about..
I have been reading through the dev section trying to figure that out and it looks like the Jedi roms retain wifi calling, and to keep it we can't go past tmos 4.3 stock ROM rev.
Not sure what TW and OP means. I can see why it would have to be based on tmo stock ROM though.
I'll dig more in the dev section.
Thanks again

Sorry, I should have been clear, TW - Touchwiz this is Samsung propriety front-end interface and Wifi calling is only supported in Touchwiz ROMS.
OP - I mean Original Post or the first post where all information about ROM is listed. OP also stands for Original Poster.
