How do you unlock phone freeze? - Samsung Propel A767 Cell Phone

The phone Freeze problem. Your phone has gotten hard-locked; it will not accept any unlock codes. This problem can only be caused by improper unlocking. Basically this happens if you or someone else has already entered 5 wrong unlock codes on your phone.
You can get the unfreeze code, NCK code and SPCK code from third party. After unfreeze your phone, you have to enter the NCK code to unlock and use it with any gsm network in the world. i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website

It freezes because you have reaches the maximum unlock attempt of your phone. Consult a phone technician to do the unlocking. They will wired your phone and probably get reprogrammed. That is the best thing to do.

Phone freeze means you enters the network code 3x wrong

If you have the original cable for this phone you can power it on without simcard.
Then get an account for the SRS online server (Unlock Samsung Online - Samsung Remote Unlock Server EN - Samsung Unlock)

now connect your phone to the computer, and install the drivers (if needed)
login to the srs server, select the correct port, and model. Now press direct unlock, and sit back. (process can take up to 5 hours). After you get "unlock done" your phone is unlocked, and the phone freeze is repaired.

I have unlocked phones and i think the best way to get your phone unlocked depending on the provider is with a simple unlock code.
Ther are sites like unlocktotalk.com and lockpop.com that offer codes a a goo price.
Most solutions the do a hardware unlock on the phone and replace the firmware with an exploited firmware just have to many problems and are very hard to accomplish. You will brick your phone if your not careful.
Taking the phone to an experienced tech would be wise, considering the cost of a new phone or a repair to fix a screwed up phone.
As for what to do with your phone now, if you want some help explain what you have done and maybe it can be reverse by someone who knows how.

If you have entered the wrong unlock code too many times, your phone will lock up.  Call AT&T for further directions.
