[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).

[Q] Need clarification on roms for T889V

Hello people,
I am sorry I have to make a new thread
I have a t889v note 2 on 4.3, rooted, with videotron 4.3 using this http://forum.xda-developers.com/show....php?t=1975560 rom, baseband T889VVLUCMK4 and I want a piece of that kitkat action. I have used EFS professional to backup NV items because I don't want to end up with a f****d up IMEI number with no reception, but I'm not sure Im in the clear to test out different roms.
This is the reason for my post, I want to know which roms I would be the safest with. I have read so many conflicting posts on this I don't feel confident enough to make a judgement call. Does t0lte roms include any modem that would conflict with my t889v modem/baseband? What about t0ltetmo ? I understand that's the part where t-mobile comes in but this post http://forum.xda-developers.com/show...06&postcount=8 says I shouldn't ever use t0ltemo, but would t889v not be closer to t889 than GT-N7105 ? In the same thread people are saying they flash t-mobile roms and then just flash the canadian modem on top and it works fine, but I would rather not mess anything up the first time around.
Anyone care enough to help? Basically I just want to know what to look for in my rom selection, I understand I don't want a rom with a built-in modem, but this is conflicting too, omnirom early builds have no modem while later builds have one?

I'm guessing you've been deterred by my post at http://forum.xda-developers.com/showthread.php?t=2684412
In my experience, ROMs for the GT-N7105 work fine. You can also try other ROMs for AT&T, and Sprint, they are usually ok. I think there are many other posts on this on XDA, so have a look.
The moral of the story is, make sure to back up your EFS partition. It's that simple.

if it is a rom that you flash in recovery you should be fine. they don't usually contain a modem or bootloader that would bork your install. You should be able to flash att, tmo, or n7105 roms with no problem

Thank you very much to both of you, very appreciated.
I went on to install omnirom 4.4 but Im not really liking the multiwindow, its a poor experience compared to touchwiz, I might eventually switch to a touchwiz ui based rom to get note 3 features and all the goodies, Im not sure yet.

As long as you don't flash a non T889V modem you should be good. When in doubt, nothing stops you from checking the zip or tar to see if it includes a modem, and removing it if needed.
If you haven't seen it yet, some recoveries recently had issues after flashing KitKat ROMs where your IMEI would show as unknown along with the phone not having service. Flashing the same ROM with another, updated, recovery fixes it.

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

I got DN4 working on my unlocked i317/ATT Note 2. But, I'm using a T-mobile sim. Phone runs like butter. Really love this ROM

SGH-T889 turned into a 7100, can this be fixed?

So I was running 4.4.4 (I forget who's build) and I just did a search on marshmallow and I saw a CM 13 so I flashed it without reading. I know, stupid noob. Anyways, my phone now says it is a GT-N7105 on android 6.0.1.
I do not like it. Before I try, I was curious if anyone knows if flashing it back is possible.
Thanks

N7100 or N7105?
i317, N7105, T889 are universal and every lollipop(?)+ROM will be branded as N7105 to my knowledge since there's no reason to maintain three different sources

I don't think there's no practical reason to not like that "cosmetic" change, but can understand the feeling. If you really can't stand it so much, you can get a build prop editor and change the model name yourself. I don't think there's any app relying on that info nowadays.
On the other hand, I kind a wonder if those three models are exact same ("universal") down to PIT level. Not that it matters unless you want to increase the size of userdata or something.

Boot into download mode to confirm the phone's model #. Once you have the model #, find the latest firmware from sammobile.com and flash it via Odin.

Will N7105 Custom ROMs run on SGH-i317M?

Hey guys,
I'm sure this has probably been answered somewhere but I have an old SGH-i317M from TELUS and was wondering if you can flash custom ROMs for N7105 on these old devices. I've noticed that only the International variants have been kept up to date in terms of development work when looking at Cyanogenmod whereas the US models have pretty much died after KitKat.
May you please advise?
Thank you.
deltatux

No, don't use anything from a different model number.

I know that other than the modem firmware, there is no difference between the sgh-i317, sgh-t889, and gt-n7105. However I don't know if the SGH-i317M from TELUS is any different from the SGH-i317 from AT&T. Some cursory googling leads me to believe that they're the same.

You can use 85% of gt-n7105 on i317 i am currenlt using Mokee from N7105, flash shift kernel firstafter flashing rom then reboot
