[Q] Factory Unlock after Root - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi all,
I recently completed my contract and received an unlock code for my ATT S3. My phone is currently rooted, but running stock. Will this be a problem when/if I enter the unlock code? I'm looking to move to T-Mobile so any advice is welcome.

Power off the phone, insert a non-ATT sim, boot the phone, enter the unlock code, and you should be fine.
The i747 does not natively support AWS so keep that in mind.

Are you running a stock Samsung ROM? Where did you get the code?

unlock code
From a third party unlock shop who is arguing that they ate sire the code is good

Are you running a stock ROM? Did you check the imei you gave them? Does the imei you get from the dial pad match the imei on the label attached to the back of the phone?

No. To SIM unlock, you must either use this utility or get an unlock code based on your device's IMEI.
Just call AT&T they'll give it to you over the phone. I was going up to Canada for a week and got them to unlock my phone for me. Well to give me the unlock code. As soon as I was up there I put in the new sim card and punched in the code and it worked like a charm.

AT&T's policy is to provide the unlock code 90 days after the purchase date (although their website states after service has been active for 90 days).

Did you insert a non-Tmobile sim card?
From my experience when there is no prompt after you enter another company's sim that usually means that the phone is carrier locked or it is already unlocked.
Google Samsung unlock methods, I know that there is a code *#7....etc into the dial pad and it brings up the prompt, a Samsung representative walked me through it before, but I forgot.
If you call them they can help you, just be prepared to be on hold forever.
Also try posting this in a Galaxy S 2 forum, maybe people have ways around it. This a S3 forum

do u remember the code that u entered plz that would be helpful
you have to be on a stock based rom... the prompt for code will not come up on cynagen. flash back to a stock rom insert sim..unlock phone then go back to cyangen
once you put in sim reboot the phone and prompt will come up...when on stock based rom
Try #011*enter your code#
Not sure if it would work or not, but I always tried this on stock roms, not rooted ones.

Do a factory reset insert the unfreeze code,will say unsuccessful but is ok,then insert the unlock and should accept it.If still not working do a backup of your current rom and flash the stock firmware and try the codes again

[Q] Is the cell unlock code dependent on RUU/firmware?

I decided to upgrade to M9. I currently have a T-mobile M8, that I decided to give away to a friend, he does not use T-mobile or live in the US.
So the question is, if I flash a HTC unlocked edition RUU, will the Sim unlock code provided by T-mobile still work?
Just dropping by....

From what I know, no, it might not work because the phone might not even ask for the code.
In order to unlock the phone you have to insert a NON accepted sim and get it to prompt for the "SIM network unlock PIN".
If this is the situation, you can try flashing and see if it prompts for the code with your friends sim card.
IF, however, it does ask for the code, just try it first. If it doesn't work you have to flash back to stock Tmobile firmware, Unlock it, then it will work with you friend.
I recommend a few sites like cellphoneunlock.net or cellunlocker.net as I have had much success with them over the years. I don't know if you are using other sites but I am just contributing what I know so far
Good luck to you and your friend! :good:

Just make sure the ROM you are flashing supports official HTC codes, I think that is how it goes.
I can say that if you need codes use cellunlocker.net , they are pretty legit.

Unlock Code

I recently purchased an unlock code from a company online. I finally received my code tonight but I'm unsure how to go about using it to unlock the device. The Device Unlock application wouldn't allow me to enter anything, so I dialed #7465625*638*# and entered the code that way. I followed a few trouble shooting techniques but it still won't work on AT&T. Does anyone have any experience with this using this device? If so, I'd love to hear what to do.
Try flashing a different Rom from another carrier through recovery. Maybe the AT&T rom. I simply put a tmobile sim in the phone and it successfully my phone through the application.

Youre saying to flash the stock rom from AT&T? Have you done this? What do you mean you put a TMobile SIM in and it unlocked it..
1. Did you have a TMobile S6?
2. Did you flash an ATT rom to it? Custom recovery or stock?
3. Did you use a code?
