Difference between SM-G900T3 and SM-G900T and ROM compatibility - T-Mobile Samsung Galaxy S 5

Hi,
I have been having trouble with Odin on my T-mobile S5. Only now I realized that my model is SM-G900T3, not samsung Galaxy S5 SM-G900T. So I can't flash ROM posted as they are for 900T, not 900T3.
Is there a repository for T3 ROM?
Or is there a way for me to use T ROM instead? The developer option has "OEM unlocking" but I am not certain what it does.
Thanks

That's probably why you're having so much trouble trying to get on KitKat. The SM-G900T3 was never officially on KitKat, just lollipop (5.1.1)

---

It has only 5.1.1 ROM -- I guess the model came out later than G900T and only has 5.1.1 ROM
Is the bootloader locked?
I've seen post that people installed CM ROM for G900T on G900T3 successfully. Does anyone know if I can flash stock rooted deodexed G900T ROM on G900T3 with TWRP?
Thanks

Yes you can. I'm in possession of a g900t3 and I can install any and all of the t-mobile TouchWiz roms. It's the same firmware as the g900t, I guess it's just a newer manufactured model.
Edit, bootloader doesn't seem locked, but there is an option in developer options to unlock bootloader anyways

It seems 900T3 will fail to boot up with 900T ROM. Have you tried it?
Thanks

Yes. I'm actively running vison-x OL1 rom. Was running the de-odex stock rom till I f'd it up messing with permissions. Both work no problems

I got my replacement phone from tmoible store, backplate has AT&T logo.. lol. So much for that. I switched with my old sprint backplate so it has no company logo. But yes, I've worked it with tmobile roms, no problems at all. No reason to goto kitkat unless u r trying to unlock all frequencies. Tmobile works in the basement where I work, sprint s5 didn't get s*** for signal there

What are the steps to install the G900T ROM? Thanks

---

Sorry for such a delay, I've been having serious health problems. Before changing roms or rooting, enter developer settings and click he "unlock" bootloader option. Then you can use the same rooting techniques as the g900t. Use Odin to flash TWRP 3.0.0-0 recovery, then reboot to recovery and make a nandroid backup. Download whatever g900t rom you would like, and flash away. I am personally using the Vision-X rom from 3-4-16. Once you have the recovery installed and have a backup of stock rom, you are good to go. And you can Odin flash any g900t baseband, modem and it will work. Even kernels from the g900t can be used, flash them thru recovery. When TWRP asks to help root your phone, deny it at all times. It seems to f up the root on the custom roms that come pre-rooted already

Sorry for necro bump but is it confirmed that the T3 version bootloader is unlocked? And you can simply load CM/Lineage as you would a regular G900T? Thanks.

if Odin fails during the Custom Rom Install and you have a ROM that is compatible with the T3 model from sammobile, then yes it is locked, if it proceeds and passes, then no the bootloader isnt locked. bear in mind it is normally that AT&T and Verizon who lock down their bootloaders to prevent downgrading

you can find G900Ts on Amazon.com (better priced than the GS7 for sure).
Mine is carrier unlocked and brandnew as of last year. I compared Specs between G900T and G900T3, same phone.
Your Firmware is here

Can't find any new non refurbished ones. The t3 version seems like only new ones out there.

As far as flashing roms goes, there's no difference between the G900T & G900T3. If you're flashing firmware, however, there is a difference, Odin won't let you flash a G900T firmware image onto a G900T3, and vice versa. I own both a G900T & a G900T3. If you're buying a used/refurb, you're better off with the T3 because it's newer. When new firmware is published, I flash both phones with their respective firmware (V1 for the 900T, V3 for the 900T3), then the 900T is rooted but otherwise stays stock, and the 900T3 is flashed with a deodexed rom, all of which seem to be built from the V1 firmware and which work fine on the T3. Whatever the difference is, it seems to be in either the modem and/or the bootloader, and it's minor enough that it doesn't effect the booting of the rom.

Thanks so does this mean I can or can't load CM/lineage on the T3 version?

I don't know how to make it any clearer. You can run any rom on a G900T3. I've yet to find one that doesn't boot. I'm currently running the G900T3UVS3GPK3 firmware on a G900T3 with the Resurrection Remix rom which is based on the official Lineage OS 14.X.

I don't think you'll be disappointed. I don't know why anyone would bother with the S6 or S7, although I do have to say the S7 looks pretty sexy.

I got mine new from B&H Photo directly at their Manhattan store since they sell the T-Mobile model new and unlocked (they open the box, unlock it, and put it back in all without touching the battery as I was explained). Only difference I notice is that the battery door is now truly plastic for the black model instead of being a rubber type material as they originally were (I owned one when it was first released, so I remember). Heat seems to be another difference, and it is more easily felt with the plastic back. Battery seems to also suck alot more than the first ones, but I read that this is a Lollipop and Marshmallow problem, and the heat it added.
Other than firmware, does anybody know any OTHER differences? 3DMark fails to recognize it.

Well I got my T3 but couldn't root. I get a message that says FRP lock when trying to root via oden which is same process I've used on other S5s so not sure if this means bootloader is locked. Any thoughts? Thanks
