[Q] Just purchased a AT&T S3 to use on T-Mobile - Rooting and Rom Questions

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?

[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] Question about custom roms on the SM-N900T

Hello everyone, I have a new T-Mobile Galaxy Note 3 running stock 4.4.2. The phones been pretty good with the exception of TouchWiz. I HATE TouchWiz. To me it is a deal breaker. I much prefer the vanilla Android experience of my Galaxy Nexus. So I'd like to know if it would be possible for me to install something like CM11 or AOSP? Or should I just exchange my Note for Nexus 5? I apologize if this has been answered before, but as a newb I haven't been able to find a clear answer in searching and I really need an answer with only a couple of days left to exchange my phone.
To skip to the question,
Would it be possible for me to install a ROM like CM11 or AOSP onto my new T-Mobile Note 3 which has been updated to 4.4.2?

Yes, you can install CM11 easily, as long as you don't care about KNOX.
You just need to download your favorite recovery(I use TWRP 2.7), odin install it. Then download the latest version of whatever AOSP ROM you want, and make a backup of your current system in recovery, then format all(excluding internal and external SD), then flash the ROM.

I don't see any CM11 or other AOSP ROM's in the TMO Original Development subforum. My favorite AOSP ROM, SlimROM, only shows the "Hlte" Note 3 as being supported. Which I think is the International N3. Can we flash that on the TMO S3's?

Yes, ALL AOSP Rom's are "Unified" meaning that the HLTE version of their roms support our device, and other hlte versions(AT&T and so on).

Thanks. That's the way it is for the S4 also.
But on the AT&T S4 original development subforums, we actually have AOSP ROM threads. Where as I see none on the TMO Note 3 subforum. Kinda weird.

[Q] Which ARHD ROM variant to install?

Hello all, I've been following the M8 forum for a few weeks in anticipation of getting a new phone on May 8th. I have a bit of a noob question though, one that I've been unable to find the answer to myself.
Which version of ARHD 5.0 should I install on a T-Mobile HTC One M8? I've been following their thread for a while and intend to unlock/root/install ARHD within a few days of getting the device. I see mentions of the international version as well as different versions for each US carrier. My understanding is that GSM carriers can install international versions whereas CDMA carriers must install their specific variants.
If my understanding is correct and you are able to install the international version or the T-Mobile version, then what is the difference?
I appreciate any help. I'm not a complete noob when it comes to rooting and flashing roms, but I'm coming from a VZW Galaxy Nexus where it was pretty much idiot proof. I've been running the same ROM for so long that I know exactly how to flash it each time a new update is released. It didn't have specific variants because the ROM was designed specifically for the VZW Gnex. So I'm a little confused by the different variants and want to make sure I don't mess anything up a week after I get the phone.
Again, thanks to anyone who takes the time to help me wade through my confusion.

You can flash any GSM variant.
The differences will be whatever the carrier has done to tweak their version of the roms, included apps, tweaked settings, signal icons etc.

Thank you for confirming that. While I was like 90% sure, it's better to have someone confirm that for me.

[Q] Roms and Such

Hello, I haven't been on android for a really long time but i was just wondering if i buy a htc one m8 from rogers, can i use any rom or do i have to use a specific rom?

Rogers is a GSM carrier .. nearly all the roms in the M8 international forums will work fine on your device
it's a good idea to update the software OTA fully before you begin the bootloader unlock / custom recovery / Rom flashing

Would that be the same for the samsung galaxy s5? If it's from rogers cause it seems like s5 has alot of models etc

The s5 has locked bootloader

So does that mean if I want to get back to flashing Roms and having the most opportunity, I should get a m8?? Cause the compaptability of Roms with s5 is limited with model??(GONNA assume that's what locked boot loader means)

Aside from ROMs specifically intended for CDMA variants (Sprint & Verizon) and dual SIM variant (if there are even any ROMs) any ROMs meant for the M8 can be flashed on your Rogers variant.
Aside from the exceptions listed above, the M8 versions are identical in hardware, aside from minor cosmetic differences like carrier logos.
You might need to update your firmware to run the current ROMs (s-off required).
