For anyone who might have bricked their device or just want to flash marshmallow on their s6 I have found the odin flashable file to do so. (Warning, make sure your bootloader is unlocked if you are upgrading or downgrading) I did a lot of research until I found this because I bricked my phone.

What process did you use to unlock your bootloader? I am under the impression no one has been able to do so on g920a.

I was not able to unlock my bootloader. But I do know other people who can unlock bootloaders from other cell phone companies who want to switch to att firmeware so I included that phrase. I bricked my phone trying to downgrade when the bootloader was locked and had to find the original marshmallow firmware so I could fix my phone. I do believe though that once you own your phone you should be able to take a phone to att and have them unlock the bootloader from my understanding. That is what you have to do anyways if you want to change service to straight talk or other carriers.

AFAIK they will NETWORK unlock, which is what you're referring to, not bootloader unlock.

No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.
You can do whatever you want to any rom, and that won't affect anything that makes it unlocked
thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....
is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,
Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

Root and carrier unlock are different things. Carrier unlock requires a code from your provider.

Would he need to do a carrier unlock even in the case he installs a new ROM on to it? (even the ODIN One-Click stock ROM?)
Sorry, just curious myself!
What he describes is the fact that in 2.1 ROM, carrier unlock code is very easy to extract from the phone (it is not encrypted). But once you flash to any 2.2 ROMs, the unlock code is now encrypted and much difficult to extract but still doable.
Flash back to 2.1 will not give you back the encrypted unlock code. So, it is important that get get the unlock code while still in 2.1 and write it down somewhere.
There are instuctions posted in dev forum about how to extract the encrypted unlock code in 2.2.
Regardless which ROM you are on, your unlock code stays the same unless you flash to a custom ROM that is not properly ported to Captivate and it will likely destroy your IMEI, product code and unlock code.

Ah I see! So much like the CM7 ROM then
So I'm guessing my phone was already unlocked somehow beforehand...
Call ATT, make up some BS about going to Europe on a trip. Tell them you already bought a prepaid sim card for an international carrier and you need the sim unlock code for your phone.

Custom ROM has nothing to do with unlock status.
Exactly, that's what I'm meaning
I've never unlocked my phone, yet it's unlocked.

How do you know it's unlocked? Are you using it on a different carrier than when you first purchased it? Are you using prepaid SIMs in it? That's what carrier unlocking allows. Rooting allows access to the base OS so you can run certain apps and make mods that involve the system. You can be rooted and locked or unlocked and you can be locked or unlocked and not rooted. One has nothing to do with the other.
I never said they had anything to do with each other, I'm much aware of how they both work. I'm both rooted and unlocked (not bound to any carrier, and yes I use prepaid SIMs).

Hi, I have a T-mobile GS6 and want to unlock it I know I need to flash METRO PCS firmware unlock it then flash back to stock but what unlocker is $20 or less and works with the S6 tmobile that is on METRO PCS firmware also while I am doing this and it asks me what carrier I am currently using do I select METRO PCS or T-MOBILE?
Thanks

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.

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!

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.

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.
So this may seem a bit of paranoia I may have but I already got my device unlocked from T-Mobilw but wondering if I flash the Unlocked Firmware (N950U1 from N950U) and then to Android Pie would I lose my carrier unlock that I already got unlocked from T Mobile by doing so. Also would Carrier to Unlock Firmware break the device?

No you won't lose it because it goes on a spot in your phone that doesn't get touched or erased when you change firmware or whatever. And no your device will not break however if you're wanting to try Android Pie there's one for the N950U1 version out now so you don't have to go all the way back to N950U.. Directions are on the forum already.

The carrier unlock is done server side at T-Mobile. Once it's unlocked, it's unlocked. Period.
