T-Mobile stock firmware on SM-G920T factory unlocked version - T-Mobile Samsung Galaxy S6

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.

Once you above a certain firmware you can't go back. What firmware you currently on?

It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.

i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?

What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Does this firmware that the device came with (G920TUEU3COK1) have any carrier branding or logos anywhere? Id like to switch if it doesn't have carrier branding

Are you getting LTE on it.

So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?

Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

Were you able to get it unlocked? I plan on doing the same, flashing the unbranded to my t-mobile that is currently unlocked.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Thank you, I guess I'll just sell this one and buy an international unlocked, glad to hear you got your phone working.

Anyone successfully updated this G920TUEU3COK1 US factory unlocked version to marshmallow? I have Samsung Pay, wifi calling, etc. all enabled on mine and would like to update, but also keep the unlocked non-bloated firmware.

Which method did you use to update the G920TUEU3COK1 US factory unlocked version? Does using the Tmo firmware risk un-unlocking the phone?

[TRIAL] T-Mobile S6 Permanent Unlock by Code

After doing some research and doing a little bit or reading, the HTC ONE M9 T-Mobile variant has the same unlocking issues as The T-Mobile S6 and S6 Edge where the software only allows for an unlock through the unlock app and will reject any unlock codes. However, flashing the International model's firmware will rid of this road block and allow for an unlock (HTC ONE M9). I wanted to try the same method with the Galaxy S6.
Wanted to ask if a brave soul who has rooted and flashed TWRP on their T-Mobile S6 could buy an unlock code, flash the XtreStoLite Pure Edition rom from the regular S6 forums and try unlocking the phone with the international rom on it. Again, this method worked with the TMobile HTC ONE M9 and will likely work for the S6. I would try it myself but I have the edge and we dont really have any ROMS at all.
Also a heads up, if you do try and it doesn't work, wait until the dev of XtreStoLite Pure Edition updates the rom to add back some important files. it may be missing some important system APk for the unlock just like its missing important APK that enables LTE
I was thinking this exact thing. I wonder if it will work...i mean if it worked on the HTC One M9, it should be the same in this situation. Also since its just a software thing, i wonder if there is a flag we can set to trick it into being unlocked as well. Thoughts?

Tried this already and it does *not* work.
All codes are unsuccessful with unlocks.
We need kernels!
Of course if I were in the market for the M9, I'd just buy it from ATT since its bootloader is unlockable from HTCDev. Or did they change that too?

Ktoonze posted a kernel yesterday - I have not tried flashing the International rom yet - someone said data is not working on it when flashed on N910t? but would love to try to unlock if data is working?
Yeah cant try this myself since the 925t doesn't have any custom roms yet. :-/.

Failed at writing NVRAM.
Tried the Xtrelite rom and did get prompted for code but the code (from cellunlocker.net) did not work.
I dunno, I have a new IMEI since I swapped for an edge. Just going to wait this out and see if it activates in two weeks once the "remorse period" passes.
Do you think it would have worked if you had used the same IMEI that you purchased the unlock code for???

Go to www.sammobile.com and download the latest firmware for metro pcs s6 (SM-G920T1) and that should work for you. according to sammobile tmobile and metro pcs received updated firmware on the same date. downloads on the site take quite some time though, just a FIY.

I think both questions have the same answer, you can't use any other firmware other than metro pcs. I remember seeing that in a different thread. If you paid it off free and clear call tmobile and they should permanently unlock it for free. I think all you need is your imei or serial number.
So can i reflash the metro pcs firmware and still have the device unlocked ?
I have purchased the unlock code off one of the leading sites on web.
I called T-mobile and pestered the hell out of them and they in return pestered the hell out me, in the end I have an unlocked phone with no flashing this and that.

I can't give you a answer but why not call tmobile like ipaq_101 did? That way you don't need to care what firmware or rom your on, it will be universally unlocked. If long distance calling is a issue you can use the online help, just make sure the first rep you talk to knows you won't stop bothering them until it's unlocked.
Is it not possible to install a ROM and then, say, flash a MetroPCS modem or something? For the record, I'm in the same predicament; I'd like to flash a ROM, but am running stock MetroPCS firmware that allowed me to use an unlock code.

You can flash any compatible ROM. I Odin flashed the MetroPCS firmware only so that I could permanently unlock the SIM. (I found that the T-Mobile Device Unlock is buggy and not exactly permanent). Then I flashed the international "F" version of Alliance ROM along with UniKernel. Been working great!
As long as you don't ever flash a T-Mobile radio, you'll stay unlocked!

Modem issues

Alright well I flashed the new COF6 modem on 5.0.2 AOCG and when I make calls it takes a good 30 seconds or more for the call to go through, sometimes it won't even go through. Incoming calls are hit or miss, sometimes it just says the wireless caller you are trying to contact is unavailable.
So I tried to odin back to the AOCG 5.0.2 modem and is passes in Odin but then when the phone boots up it says baseband unknown with a X through the signal bars. Tried to odin the full 5.0.2 firmware and same thing, unknown baseband. I did a full wipe before I tried the full 5.0.2 firmware. Not sure what's going on. Any help is greatly appreciated!

Yes, tried both ways, manually and booting DL from TWRP. I Just odined the full 5.1.1 and now I lost domestic sim unlock, what a PITA.

Just remember to never flash a T-Mobile radio, or it will re-lock the sim!
The Metro radios work fine with T-Mobile and AT&T networks.

Carrier unlock a G920T permanently

Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock
Sent from my SM-G920T using Tapatalk
Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help

Thanks I figured it out.
Just in case someone stumbles on this thread I will post the solution.
You will need to flash the US Unlocked version of the phone then flash which ever carrier you want.
Just for clarification purposes, are you saying that once you flash the ATT firmware onto a Verizon device that all ATT functions work? Or did you have to also provision the IMEI to achieve this as well.?

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

I am looking for the AT&T firmware. I am currently in Kuwait and destroyed my phone. I had to buy an unlocked Note 9 version with the exynos cpu. The problem is I can't WIFI call or use any of the Volte functions my other phone had. Does anyone have the firmware for AT&T? Will that only work with snapdragon? I have already rooted this phone and it is ready to go. I need these functions so I can call back to the States.

Thanks for the quick reply. It looks like I need to wait for Detonator to come out with the AT&T zip. It says coming soon so hopefully soon is in the next couple of weeks. That looks like the best route to go. This is the first phone I have ever rooted. I work with networks and sometimes software kicks me in the butt!

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.

Thanks for the info. I read up on all of that and the trade off is worth it. I just need all the Volte features and hopefully the correct frequencies for the U.S. I had a note 3 forever and it got destroyed. I loved that phone. This Note 9 is awesome but without being able to manipulate the IMS settings it is a PITA. I just want to be able to call home from time to time. Emailing the wife is no fun especially with the tech available today. I will keep an eye out for Detonator to provide the AT&T CSCs and all that fun stuff. Then this phone will officially be outstanding. I do have to admit that the rooting process was fun. I am all about modified anything. Stock sucks. LOL

Im not a phone guru like others on here. But from my experience that is all I did. A really important step I didn't mention is leave the cable PLUGGED IN when you flash the unlocked software then the locked software. This caused my device to read the "sim info" and provision its self for ATT and get rid of the verizon stuff and install the ATT stuff. Hope this helps you out.

I flashed the us factory on my note 9 from Verizon. I have LTE voice and wifi calling. Didn't trip Knox. No root required. Any particular reason you want tmobile firmware?

Because my carrier is T-Mobile and my Note 9 came from Verizon. Can you provide a link to the factory firmware? Im hoping to flash to factory unbranded, then flash to t-mobile so I can use my video calling.
Thanks for any help
