What is a defreeze code?

Answered by Michael Wilson

A defreeze code, also known as an MCK (Master Control Key) code, is a unique unlock code that is used to unfreeze or unbrick a phone that has been locked due to too many incorrect unlock code attempts. When a user enters the wrong unlock code multiple times, the phone gets locked and displays a “Phone freeze” message.

The purpose of the defreeze code is to reset the phone’s lock counter and allow the user to enter the correct unlock code. It essentially unfreezes the phone and restores its functionality. Without the defreeze code, the phone remains bricked and unusable.

To understand why a defreeze code is necessary, let’s dive into the technical details. When you input an unlock code on your phone, it has a limited number of attempts to accept the code before it gets permanently locked. This is a security measure implemented by phone manufacturers to prevent unauthorized access.

If you exceed the maximum number of attempts, the phone enters a frozen state, also known as a phone freeze. This freeze is designed to protect the phone from potential hacking attempts or unauthorized access. The freeze is triggered by the phone’s firmware, which detects the repeated incorrect unlock code entries.

When the phone is frozen, it will display a message indicating that it is locked and cannot be used until the correct unlock code is entered. This is where the defreeze code comes into play. The defreeze code allows you to bypass the frozen state and enter the correct unlock code, thus unlocking the phone.

Obtaining a defreeze code usually involves contacting the phone’s manufacturer or the service provider from which you purchased the phone. You may need to provide them with the phone’s unique IMEI number, which can usually be found by dialing *#06# on the phone.

Once you have the defreeze code, you can enter it into the phone following the specific instructions provided by the manufacturer or service provider. This will reset the lock counter, allowing you to enter the correct unlock code and regain access to your phone.

It’s important to note that the defreeze code is different from the unlock code. The unlock code is specific to each phone and is used to remove the network lock, allowing you to use the phone with any compatible SIM card. The defreeze code, on the other hand, is used to unfreeze the phone and is not related to the network lock.
