T Mobile S4 on AT&T - Which Roms?

Hey everyone,
I'm definitley not a noob at flashing roms / rooting / unlocking , etc....Been flashing phones like crazy the last few years (s3,note2,htc one,nexus,etc)But I have one question that I cannot find the answer anywere.. I bought a T Mobile S4 which was blacklisted on T Mobile so I am using it on AT&T wtih full LTE.. Which Roms do I flash for this thing? Do I flash TMO roms or ATT roms, or does the kernal flash just matter? If this is a stupid question, sorrry! lol. Just don't want to brick this thing.
Thanks Guys.

Not trying to sound TOO condesending, but you haven't read much of anything in these forums if you couldn't find your answer to that. All variants of the S4 can flash each other's ROMs as long as you immediately flash a kernel for your specific device. You have a T-Mobile device so you will need kernels from this section; but you are free to use ROMs for the AT&T, Sprint, i9505, etc. Just don't flash anything via Odin that's not meant for your specific device, and don't flash anything at all meant for the Exynos version (i9500).

Yeah I know most ROMS support all Variants but I wasn't 100% sure. I must of been searching the wrong things....I was confused with the kernal flashing as well. I have always owned a Carrier Specific device and never have used an unlocked device thus far, so I was a bit confused . Thanks for Clarifying though! :good:

Infamous S4 ROM has an Aroma installer that will support multi carriers.
Look at the change log for more details.

How are you still using the blacklisted phone if it's blocked for tmobile? Thought the two carriers shared imeis?

I was going to say the same thing. If you're blacklisted on T-Mobile, you'll be blacklisted on AT&T. I have a blacklisted T-Mobile and any sim (even international) is blacklisted while in the US. However, in other countries, it works fine.

[Q] unlocked Samsung Galaxy SIII on AT&T network

Hi,
I have SIM unlocked, rooted Tmobile's samsung Galaxy SIII (SGH-T999); put AT&T SIM card and it is working fine. As a fundamental question on loading custom ROMs, should I be picking ROMs from AT&T forum in XDA or Tmobile in XDA??? So far I have been using Avatar/Liquid Smooth ROM built for Tmobile....still it doesnt make sense to me as i am currently on AT&T....I dont want to brick my phone by doing something wrong.
Can someone reply?
Thanks
Mahesh
BTW - ignore my signature....i am unable to edit them - dont know why - there is no option to edit signature!

You should flash rom's specific to your phones hardware/model number. It seems to me *most* of the hardware is the same between the i747 and t999 from what i've read but always best to err on the side of caution.

by doing that, in my case, would my ROM be optimized for AT&T??

Most likely, but tread with caution. The only issue you might encounter are APN settings that you could always edit manually. From what I understand, the T-Mobile Galaxy S3 is almost identical to the AT&T one, and in certain cases, some people have been able to run T-Mobile roms on the AT&T one.

The only thing that is carrier specific as far as custom ROM's are concerned is the ability to connect to the network in question, its the hardware the ROM is designed for that is important, minus any carrier bloat apps that may be included in a ROM (non issue if using an AOSP based ROM). Flashing software to an unintended device will most likely be bad news. As drx said worst case you would have to manually enter the apn settings. If i recall the only real difference in the TMo and ATT S3's is the fact that the T999 can connect to the 1700mhz band and the i737 can't (natively).

Sweet ROMs in the international forum

Hadn't been over there in quite a while, but the N7105 forums have some sweet ROMs if you're looking for a change that should work fine on our phones...
Currently running "CM Remix" which has everything but the kitchen sink for an AOSP rom, and so far seems very smooth and stable

How can you tell if a certain rom will work on the att variant?

They should all be safe to flash. Same hardware on the internal LTE variant.
The build.prop and APNs may vary slightly, but many of the ROMs in this forum are exactly the same as their international versions anyway

By checking for a modem in the zip as the n7105 modem isn't compatible with AT&T or t-mobile. If modem is in the zip I usually just replace with proper modem for your carrier.

Mine is the ATT variant but unlocked and used in Central America. I'm guessing it will work with any modem?

No since it's AT&T you will need an AT&T modem in the phone as any other modem will cause an unknown baseband.

Got it, thanks!

Still running the ROM I mentioned in the OP, and it has too many features and too few flaws (none!) for me to try any other!
New build made yesterday - gonna try that, though
BTW, didn't have to change anything to get it optimized for the ATT model- even the APNs were all set up (unless maybe I restored settings that I wasn't aware of)...
1st Nov 2014 (ver 3.0.5.0 STABLE Fix)
Kernel : bundled with latest agni kernel ( Boeffla Sound version with new wifi module)
Update SuperSu to ver 2.16
native support to F2FS (no need to flash any convertor, native support F2FS partition of System. Internal data and Cache partition)
Fixed ART mode * (1 st Nov 2014)

Looks like a great rom!. I'm assuming this rom is ok to flash for any LTE variant (Bell) since it doesn't include a modem?

Should be fine! Just back up as you always would with TWRP and make sure you backup the modem as well. That way you'll always have one backed up if you need it just in case...

Yep, as long a modem isn't included in the zip (which it *typically* isn't in the case of AOSP based roms), you're good to go.
I personally don't even flash t0lteatt roms when they're available and instead use their t0lte counterparts, as the t0lte versions are sometimes more likely to be updated more often (and in some cases the t0lteatt device tree has been abandoned entirely!)
And if anyone's wanting to build a rom from source, while we're on the topic of AOSP roms, the t0lte tree is the way to go as far as the Galaxy Note 2 LTE models are concerned.

What reminded me to check the international forum was when I went to deactivate my old phones in Google Play Music, I noticed most of them were listed as an N7105- and all of the ROMs were downloaded from this forum anyway...

I was wondering about trying Roms from that forum too. I kept seeing posts where someone said something about a DN4 Rom. So I looked it up and downloaded..........only to find that it is not one of the Roms that works on our phone.......as of yet. It did flash and start up, but before I could make it past the welcome screen, I got a bunch of pop-ups about various items "quit working." And they kept coming back. And then I had the unknown baseband with no signal.................basically it just doesn't work. Damn shame too, cause it looked so nice. But this did make me look at the other Roms and I will be trying a few of them. I must say though, DN4 had my mouth watering for the GN4 experience on my 2.

You can only flash roms from the n7105 section. The roms in the development and original development sections won't work

CyanogenMod question.

Hello guys! So I just had a quick question about the t0ltetmo ROMs from CyanogenMod. I asked on their Facebook page but some jack off that "works for CyanogenMod" was just rude as hell, and called me stupid. So does anyone know if CyanogenMod unified the t0lte ROM and is safe for flashing on other variants? The t0ltetmo, t0lteatt etc. Thanks guys! And if you could, send me a link where they announced that? I saw the post that said they were going to make a unified ROM but they never posted and said it was done. Thanks all!

From my experience if you see t0lte, t0lteatt, t0ltetmo, N7105, it should be fine to install if your device is any of those you just may happen to flash a modem afterward if the ROM includes one and it isn't your device.
In short, it's safe.

Thanks! So even if the ROM wasn't unified, it has no way of bricking my phone real bad? If it doesn't work, it can be restored with a backup? Cuz yea, I have the t-mobile version, and the ROM I'm talking about was made for the international. It MAY be unified, not sure.

I've been flashing all sorts of ROMs under the previously mentioned codenames with no issues. Stay away from other Galaxy Note II codenames though, N7100, i605, l900

Thanks for your help man! Also, which variant do you have?

t0lteatt. Wish I had the t0ltetmo since I'm on T-Mobile and this ATT one won't get LTE some reason

Are foreign roms considered safe?

I hope this doesn't come off as dickish or ignorant... but I'm wondering if there are any concerns about installing roms originating from other countries (particularly MIUI from China). Would we know if there was malware built into these roms?
I've never read anything bad about flashing these roms, and I hope the question is not offensive.

Flashing any rom from a different carrier/device model can and will mess up your phone. At the very least it would need to be ported to work on your specific device 7 carrier. If flashing international roms worked out of the box we would not be seeing ports. so don't flash an international rom because you will be finding yourself doing a bunch of things in order to get your phone working again. The rom MUST be ported before it will work on a different device & carrier. Some gsm roms might be more compatible but you will be better off avoiding international roms unless it is has been ported correctly and the dev specifically states it is for your specific device & carrier.
