At&t - Wanna unlock for all carriers

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).

if your phone has root access simply download galaxy s unlock from the market by helroz and run it. it's pretty simple. to know if you have successfully unlock your phone just dial *#7465625# it should should show network lock off. and you"re good to go any carrier sim you want that supports your phone baseband. if you're not at&t way to go....

[Q] Questions about unlocking and rooting after Samsung 2.2 update

OK first post here. I have done a fair bit of reading and searching but still have a couple of questions. I have just bought a Captivate. Made 3 phone calls with it and that's it. It has already been rooted and unlocked by the seller. I know if I upgrade to 2.2 via KiesMini it will remove the unlock and root. After the update can I unlock and root again. ? I hear Super One Click might root it. I have the code numbers from the original unlocking. What can I use to unlock it? Thanks

you dont lose the unlock by updating it. even if you did, you have the code so it doesnt matter. you dont need it unlocked if you are staying on ATT....unlocking is so you can stick another providers SIM card in and use it on any GSM carrier

I am not on AT&T. I have an AT&T phone that's used on Roger's. That's why it needs to stay unlocked.

if you have the code then it doesnt matter if the unlock goes away.

Use the SIM you intend to use plus the code previously extracted. [APP]SuperOneClick v1.7 (Root, Unroot, Enable Non-Market App works on Froyo.

Update. Unlocked and rooted phone. Updated with Kies Mini to Froyo 2.2. Phone remained unlocked after update. Root was gone. Used SuperOneClick 1.7 and root was back. No problems at all.

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

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 !

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

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

Have you tried with the tmobile device unloced app.? If that doesnt work then head over to this awesome guy, he can help you unlock it remotely. https://forum.xda-developers.com/tmobile-galaxy-s6/general/sim-unlock-honestly-free-t3601740

fyi regarding sim unlock and rooting

Fyi if you root before you sim unlock tmobile says it locks out the app and you cant sim unlock it.ive been going round and round the last week with tmobile over this.they say it cant be sim unlocked because it shows in their system as rooted.even though i did a kdz restore on 20o the unlock app doesnt work and tmobile cant over ride it they said they tried and it failed.on the app i keep getting error device not recognized by your service provider call customer care

yes, this is true, i actually had very same issue, tmobile keeps telling me the device is not theirs because it is rooted lady said she tried to override but cannot get it through. ish i would have known this before rooting. is ther anyway we can trick it to look like it is not. i figured rooting would not matter as long as have stock rom. guess not

I rooted my device way last year when it was in 20N. I had it rooted and was able to unlock to phone. Was running stock at the time. This is kinda scary. Its also a shame really, maybe something tripped in 20o that detects root. Who knows.

Couldn't you just flash the 20o KDZ and get back to stock? Then unlock?

your answer can be found on OP.

I have no problem to unlock with the app.
Mine is 100% stock rooted (with adapt client removed).

I revert to the 20i rooted by MicroMod777 (http://forum.xda-developers.com/tmo...-mm-20i-global-20e-stock-rooted-roms-t3317932) and then perform the Device Unlock app. It worked while I'm running that ROM, but once I revert back to CM13, it ask for a SIM network unlock PIN.
I contacted T-Mobile and has been stonewalled that they don't provide the SIM network unlock PIN.

I'm on rooted Extreme rom and I'm unable to unlock using Device Unlock app (Unlocked Failed: This mobile device is not eligible for unlock) despite TMobile said my device is eligible through multiple chat sessions.
Now I'm going to go back to stock and try again

Found Marshmallow odin file!!!

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. Enjoy. http://www.theandroidsoul.com/download-galaxy-s6-stock-firmware/

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.
