I'm looking to get an Galaxy S5 for AT&T, and am wondering how I would update my ROM when using the G900T (T-Mobile)
My understanding is that the G900T comes with unlocked bootloader. I would be getting that model for specifically that reason "just in case" - i.e., if down the line I want to use an alternate ROM.
In the meantime, though, I want to use whatever the most "official", straightforward (i.e., "most approved") ROM I can, even if this means being "behind" on the latest and greatest.
Does this mean that I use the T-Mobile ROM? Or the AT&T ROM? Can I update OTA (as is my preference)? If not, what would be the most straightforward method of updating the ROM?
you would need to get a sim-unlocked G900T, and then you can just put your ATT sim inside and it works.
Not sure if you'll receive any OTA updates if you're not using a tmobile sim though. Most of the newer phones are already on 5.x, you you'd be pretty current.
I got an unlocked G900T last week and put a custom touchwiz rom on it from the att dev section, and it works just fine.

Hey guys,
I unlocked my galaxy s4 from AT&T and now I use T-Mobile. I was wondering if I could use the t-mobile rom since I would like to use the tethering and wifi calls from it.
I don't really want any custom rom, just because I'm fine with the carrier ones.. so I searched somethings and I figured out that I could use the t-mobile rom with loki doki.
Can I just instal the stock firmare of t-mobile? (It would be the M919UVUEMK2)
By the way, right now I'm running the MF3 and idk why I don't receive the OTA update (never received, I suspect that's because I unlocked it)
I found some other posts but unfortunately it doesn't contain enough information.

Can anyone help me ?
Thanks!
This is really confusing. Most of the threads are written such that 'how to root while updating to OF2/OF3'...it doesn't tell me which versions allow rooting in the first place? Any help. Coming from the GS3
As far as I know, the S5 Active is only available as an AT&T phone, which means it will have a locked bootloader and any somewhat newer firmwares will be unrootable. Pre-lollipop builds (Anything below OF2) are rootable but still have a locked bootloader.
Just a word from the wise, don't get an S5 Active, and DEFINITELY don't get an AT&T phone. a GS5 (regular) with a thin case (Spigen slim armor or neo-hybrid/ otterbox commuter) will be WAY more durable anyway, plus it's still waterproof/dustproof.
Get yourself a G900T (T-Mobile variant), or a G900AZ (Cricket wireless variant --Cricket is a subsidiary of at&t--), or even a G900F. Those all have unlocked bootloaders and will allow you to root, install custom recovery, custom roms, whatever you want forever. I personally have a G900T using it on AT&T with no issues, as the G900T supports all the same frequencies (and an extra one!) as the G900A (AT&T model). The G900F doesn't support every single band AT&T uses, so I would pick one of the other two if you want 100% compatibility.
MAKE SURE if you buy a G900T or G900AZ that it is UNLOCKED or you won't be able to use it. And after you get it, you'll have to call AT&T support and give them the new phone's IMEI number in order for LTE to work.
Hope what I said makes sense..
FYI The best place to buy a phone is always (XDA's own..) Swappa!

I habve an at&t variant OC5 phone available on Swappa should I get that or not, because I can't find a rooting guide for OC5
Or are you saying buy unlocked so you can use it on AT&T?
Problem is I can't find the SM-G900AZ anywhere used....might just go with the Zenfone 2 . DISSAPOINTING SAMSUNG and ATT I loved the GS3 and was looking forwar to the GS5
Which frequencies does the T mobile version NOT share?

The T-Mobile version shares all the same frequencies plus includes an additional frequency which AT&T does not use, so therefore the T-Mobile (G900T) retains 100% compatibility with AT&T. Yes, if you want to use a G900T on any carrier besides T-Mobile it will have to be unlocked. Luckily it's not hard to find an unlocked G900T.
Let me make this clear: If it's AT&T and it's a Samsung phone and it's on lollipop, don't expect to be able to root it. Go with a T-Mobile or factory unlocked phone.
I'm new here but have been following xda for years. I'm not new to rooting or flashing custom roms but after a few days of searching I can't find an answer to the following question.
I have and unlocked Verizon Note 4 n910v running Android 4.4.4 on the Cricket (AT&T) network. If I'm going to install a custom rom, do I need to find a rom for Verizon or for AT&T? Also can anyone clear up the rumor about a locked bootloader on this device? Any help would be awesome!
If you have already unlocked the bootloader on the 910V, I'm not too sure what rumor you are referencing regarding a locked bootloader ::
As far as roms go, it's a Verizon device so you need Verizon roms and firmware.

For ROMs, you must install verizon ROMs because the phone uses verizon-customized hardware.
It is no rumor that this device comes with a locked bootloader. However, thanks to the talented devs here at XDA, there is now an official way to unlock the bootloader; but you have to update to Lollipop 5.1.1 and BPA1 baseband.
I'm using a T-mobile sim in my verizon note 4 without unlocking the bootloader on lollipop and BPA1, so you shouldn't worry about your sim not working after updating. Have fun!
you have a misunderstanding of unlocked. what you are referencing is that you are using the factory unlocked gsm portion of the modem in the verizon model phone. you are NOT bootloader unlocked as you are still on 4.4! if you want to truly unlock it (as in the bootloader) then you will need to upgrade to 5.1.1 (BPA1) via odin. There are several tutorials on how to achieve this, and unlocking (including one that i wrote on the main thread).
to answer your question about using a verizon rom or a t-mobile rom, you can try any snapdragon rom that you would like, but there is NO GUARANTEE that they will work as each developer compiles with or without certain components. what ever you do, do NOT try to flash other carrier (at&t, t-mobile, sprint, etc.) firmware. BIG NO NO! although you claim to have experience with rooting and flashing roms, i would advise you to ALWAYS stick with the carrier variation of whatever device you are working with until you get a better understanding of the different components to a phone i.e. bootloader, modem, rom, etc. xda-university has a nice explanation of these things. so go read up on these things. if you need help, feel free to ask.
Thank you for everyone's advice. Upgrade to lollipop via Odin and bpa1. Got it. As far as custom rom goes, use a Verizon carrier custom rom.
Looking to pick up a GS5 and put on Nougat via LineageOS. Is there a certain carrier's phone that is more desirable than others? Since I do not already have the phone I would like to acquire the best one to get to my ultimate goal of unlocking and putting on Android 7. Phone will eventually be used on the AT&T network.
Thanks in advance,
Bob
Try and see if the international G900F works on AT&T, or simply get the G900T, to not go through the hassle which involves an international version.
If you like using custom roms and such STAY AWAY FROM AT&T!!! Bc they lock there bootloader's haha
AT&T Galaxy S5 has Locked Bootloader, which means you can't flash custom ROMs. Sprint variant has different hardware for CDMA support, so some ROM may be incompatible. If you can invest on G900F (International Version), G900F is the most ideal one for custom ROMs (Or G900W8, which is Canadian version) Otherwise, you would want to get G900T since it has unlocked bootloader.
I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
