G920T root/custom goodies on the G920T1 - T-Mobile Samsung Galaxy S6

Hey guys,
So I just bought bought a G920T1 and I am aware that it is the same hardware as the G920T with a few software differences (missing download booster). Knowing this, is it safe for me to use the root methods/custom recoveries/custom firmwares of the G920T on my phone?
Thanks

Yes. And by custom firmwares I assume you mean custom roms

Yup, they are exactly the same phone. So use Unikernel to root, TWRP for recovery, and firmware of choosing.
One thing tho is if you wanna use the unlocking method with Metro which use codes. Then don't flash any TMO modem and bootloader as you will lose the unlock. Just update them to lastest 5.1.1 from sammobile or OTA if you need to. Other then that you should be good to go.

I bought the phone off swappa and it was listed under the T-mobile S6 section, but I noticed that the model number in the pictures was G920T1. I'll probably ask the seller how he unlocked his phone. So flashing a custom ROM should be fine, right? Based on my previous experience flashing my older S3, flashing modems were usually a different .zip than the ROMs and I don't really remember all too much about bootloaders.

Yeah flashing custom rom is fine as they don't include the modem nor bootloader. It's just that most newer roms require you to have the lastest bootloader and modem for best experience. Sorry didn't mean to confuse you more, but G920T and G20T1 are the same phone. Some people just swap firmwares between TMO and Metro as the G920T1 is easier to unlock. I have the same version G920T1 and bought code off of ebay to unlock easily.

Alright, then can I upgrade to the newest Metro bootloader to keep my unlock and then install the newer ROMs? Or would I lose my unlock that way.?

Hello again, about to get my S6 soon and was wondering if you could point me to some root methods that would work without breaking fingerprint scanner or tripping KNOX. It's been awhile since I've been back in the rooting scene and was hoping you could point me in the right direction. Also, if I want to keep my unlock and upgrade to Tmo 5.1.1 stock, I would flash the Tmo ROM with a Metro bootloader?

[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.

Once you unlock with the MetroPCS firmware, do not ever flash back to T-Mobile firmware, or you'll end up relocking it! You can flash any compatible ROM, just not the T-Mobile radio firmware. ROM'S never include the radio firmware, so you should be fine.

Ok and really quick, lets say I used the unlock app to get a temp unlock and froze it to kind of make it perm could I flash another ROM and still be unlocked?

No, it's not that easy! You need a real unlock to make it permanent.
You just need to decide which route to take to unlock it.
I did the MetroPCS firmware and then traditional sim unlock, and then custom rom.

But what if I went back to tmobile stock and then I would lose the unlock BUT after going to the tmobile rom which would make me lose my unlock could I go back to a metroPCS ROM and unlock with the same code?

No, It's the low level firmware that's the key to the unlock.
MetroPCS firmware = traditional code unlock
T-Mobile firmware = proprietary device unlock
After you're unlocked, you can change the ROM all you want. It's the low level firmware that you must be careful with (mainly the radio).

Do you mind pointing me to the guide you used to root and install recovery on your S6.
I just unlocked mines using the metro firmware and I don't want to accidentally install the T-Mobile firmware
Thanks

Don't download and Odin flash the T-Mobile firmware or radio, and you'll have nothing to worry about!
Rooting is simple on an unlocked bootloader if you don't mind tripping knox.
1. Odin flash TWRP.
2. Boot straight into TWRP after Odin flashing (vol-up + home + power)
3. Flash SuperSU from TWRP
Done, profit!

Hey! I do have the same question as the person that created this thread. When I flash the MetroPCS firmware should I select MetroPCS or T-Mobile on a 3rd party unlocking company to buy the unlocking code? Thank you all!

MetroPCS, that's what I did and it worked fine if you flash the MetroPCS firmware.
I need to get my S6 to show the Tmobile Logo on bootup so I can Jump to the S7. I had flashed it to MetroPCs for the unlock. I thought if I went the Odin route and installed the Tmobile software it would change the bootup Logo but so far after running Odin it still boots up with MetroPCs.

Which MetroPCS firmware did you use and where did you get it from?
I have a SM_G920T on TMobile 5.1.1 Baseband G920TUVS3DOJC and I tried flashing the G920T1UVU2COF9 MetroPCS firmware from sammobile and I get a FAIL message on Odin.

I Odin'd the MetroPCS firmware (G920T1) a long time ago, and it was newer than the TMo firmware the device had on it at the time. I think you're failing to flash because the MetroPCS firmware you used 2COF9 is older than the Tmobile firmware 3DOJC you already have on it. That's my guess.

Need help regarding my NEW S6 G920T

Okay so i have read a few thread posts but all this seems a bit too confusing. Here is the situation. I bought a used S6-G920T which is unlocked as of now, i don't know what method was used to unlock it since i bought it pre unlocked. My sim(Non T-Mobile) is working fine. I am on 5.1.1- BASEBAND: G920TUVU3DOJ7, what i want to do is update to marshmallow, the official OTA isn't really available as it says the system was tampered with. I want to know if it is safe to update to 6.0.1 via odin without losing my unlock. Thanks in advance to anyone who bothered to read through.
BTW as of now i don't have root access.
What do you mean when you say you're unlocked?
You can use Odin to update the phone to newer baseband and bootloader; you can then use Odin to flash TWRP, and install the ROM of your choice.

I'm pretty sure the phone unlock has something to do with the IMEI of the phone being tied to the carrier. If it is unlocked, you should be able to use it on any carrier. It sounds like the process takes place in a special partition that is at the lower levels, like the bootloader, and does not change regardless of what software is used on the phone. I'd say just go for it and update, I can't see any reason why it wouldn't work, even after an Odin flash.

[Q] Update N910T with stock firmware w/o updating bootloader?

I have an SM-N910T running N910TUVU1COG2. I've kept it at this because I didn't what to lose the unlocked bootloader.
Is it possible to update my N910T with stock firmware without updating the bootloader? I've done it on other Android phones without any problems, but am clueless about the Note 4's ability to do so. What say you all?

Well, that totally sucks. Damn Samsung/T-Mobile. One of the main reasons I bought the phone was because it had an unlocked bootloader so that I could do as I will with it. It was bought out-right, unsubsidized, and I should be able to install what I want without worrying about the bootloader getting locked. So I guess I'm stuck at COG2 for a while longer, at least until my desire to keep the bootloader unlocked is overcome by my desire for new hotness.

If once you upgraded to marshmallow you can only downgrade to 5.1.1 OK1 but no 5.0 or 4.4.4.
But with 5.1.1 OK1 bootloader you can still flash 4.4.4 and 5.0 roms with custom kernels and they work flawless.

Only revert lock. But if you are looking at rooting, recovery and flashing roms its not locked. I took mine to PE3 MM and left it there.....
OK, I'm confused.
Sorry to belabor the point, but I'm confused. If the bootloader is unlocked, then should I not be able to flash any ROM, Samsung's or not? i.e. I don't understand how the OK1 bootloader, if it's unlocked, will prevent me from flashing COD2. Or is it that the bootloader itself will not properly boot anything prior to OK1?

TWRP and ROMs for Note N920A w/ Nougat

Bootloader
I recently talked to at&t about getting my bootloader unlocked and a supervisor told me the only way to do so without bricking would be to being it in to an at&t store and they will unlock the bootloader.. anybody else have this told to them?
They're most likely taking about a Sim unlock not bootloader. Also there is a method for rooting it but you have to be on a specific bootloader and you can only use it on lolipop.

Ya, I know about that root method. Unfortunately, my phone decided to update itself a few weeks ago and now its on BL 5. So that's pretty much a no go.
In relation to bringing in the store for a BL unlock, I did specifically ask and made sure the tech I was speaking with knew the difference between BL and sim unlock. In fact, i made it very known that my radio was already unlocked, I done that weeks before i talked to her.
