Hi,
First of all I hope this has not been covered, I searched but found nothing.
I recently bought an unlocked Captivate from the US, I am in Australia. I put my sim in and all was good. Used it for about 4 weeks and then one day turned it on and said on the screen 'you have entered an incorrect unlock code, please contact service provider.'
Now I never entered a code or even had a chance to enter a code. Now it will not let me use any sim at all or even give me a chance to enter and unlock code, which I have obtained using the one click unlock found in this forum.
The phone is rooted but was working fine when rooted originally.
Can someone help? I can still use phone with wifi just not sim. I have tried a hard reset and that still has the same problem. I have tried flashing it back to an older rom, same deal.
What can I do? I can't even enter an unlock code to get it unlocked.
All sim based devices have a PUK code...contact your provider, ask for it and then try to unlock your phone till it ask for it...then you can reset it...that'd what I would do.

Hi, i bought a factory unlocked captivate from USA and never had a problem with custom roms. The sim never got relocked and i had flash over 20 roms on my phone. And i live in Argentina, without any access to an AT&T sim.
Though i would suggest, that you try to get your unlock code written down somewhere before you do custom roms, specially if you did not buy it factory unlocked. There is an app that gets the unlock code for you, I can't recall its name. Some of the phones get relocked after going back to stock; though I'm not sure if it is because they where manually unlocked instead of factory unlocked. What I do know is that when i tried to get my unlock code it wasn't anywhere, so I started flashing the phone hoping it didn't get sim locked.
If you don't get the code, flash and get sim locked there are several posts that explain how to unlock your phone. Those and the "universal sim unlock" gave me some peace of mind at the time.
Thanks!

Back up your efs directory. It is possible to relock and be stuck if you don't. There is no factory unlock captivate. All are att and have to be unlocked via code.

Ok, I purchased an unlock code and unlocked successfully. A few weeks later, I sent out for repair for GPS lock-on issues, and recieved the same exact phone back(s/n and IMEI's match). I am really not too sure if the phone is unlocked still or not but I don't think it is because I cannot delete the T-mobile APN.
I tried to unlock the phone by using the 2945#*999#, but when I enter the unlock code that I have purchased, it says unlocked unsuccessfully.
Does the unlock code change or stays the same always. If it stays the same, why am I having a problem? I tried inputting twice. Please help, thank you.

Did you try inserting "a SIM card not attached to your current provider (e.g if you have T-mob use an ATT SIM CARD) and turn on your phone?" (credit sanfranx415 post) edit: maybe try a different gsm carrier in the same country you reside.
From what I have read and understand different versions of busybox will work or are compatible for different things (maybe somebody will tell me if that is not accurate).
Here is a video that might help.
Good luck!
Try contacting t mobile and tell them your going overseas for a few months and want to take your phone with you and is there a way to unlock it so it can be used in another country.

When you insert the sim card and power up the phone, as you unlock it it should give you a network lock screen that only lets you use the phone after inputting the unlock code.
hey, I tried to unlock this cell phone (SGH-T679) for few days now
but I failed to unlock it
it's really tough to unlock it i guess
Tried using several unlock Apps from android market but they didnt work ;(
and I even bought a code from a website but it didnt work either lol
nah.. can someone please help me out to unlock this phone?
it is originally from T-mobile but now i'm using Fido (in canada) ... so have to unlock it ASAP
If the phone is from T-Mobile, and you are using it successfully on another carrier, then it is already SIM unlocked.
EDIT: Nevermind, I called ATT to double check and they gave me a different code that worked. Sorry for the post.
I know this gets asked alot, but the information, situations, and answers out there are so many it is difficult to determine what needs to be done, so I am hoping someone can at least point me in the right direction.
I had unlocked my bootloader using htcdev, installed 4ext recovery, and flashed latest Cyanogenmod. I have been wanting to switch to T-mobile (I know about the possibility of not having 4g with that) and come to find out, entering the Network PUK code doesnt work in Cyanogen..
I gleaned that I needed to re-flash stock rom and then try to unlock, but I did this, and it still isnt accepting the code, argh. Do I need to relock my bootloader or do anything special? I got this code straight from ATT. With the ATT SIM in the phone, it doesnt ask for it, I restart phone with my T-mobile SIM in, and it asks for the code, but always says its incorrect. How is it checking this anyway, as it doenst seem to be communicating over the mobile network.
Any ideas would be much appreciated, thanks.
