Troubleshoot your unlocking process for Samsung phones

  • Failed to request
  • Unlock code request unsuccessful
  • Failed to unlock network
  • Your attempt failed

#1 You or the previous owner of the mobile devices might have entered too many incorrect codes. This situation is also known as “Phone Freeze.

#2 The mobile device does not run on an original ROM or the ROM installed in your mobile or tablet is a customized one. The provided unlock code will only work if the ROM installed in the device is original.

#3 The code you entered is wrong. This may happen if you entered an incorrect digit or missed a number from the code. In this case, recheck the code you have and match it carefully with the one you entered in your phone. If both the codes are same, contact the cell phone company who provided you with the code. They may have given you the wrong code. Although this situation is rare, it can happen.

Phone Freeze Scenario
To rectify this error, you require two codes. The first one is the Network Unlock code, also known as NCK Code and UNFREEZE or DEFREEZE key, also known as the MCK key.

Remember, to keep your phone safe and bug-free, before starting any process switch off your device correctly. Now replace your old SIM card with the new SIM card, switch on the device and enter the PIN in the device.

When you see the “Phone Freeze” message, enter the UNFREEZE or DEFREEZE code and confirm by pressing “#” or “OK” or “Call” button.

Do not worry if you see the phone screen to be blank. This is normal, and your phone has no technical faults. You keep on typing the code blindly.

Another way of doing this is when your device shows “Phone Freeze” error, enter “#7465625*638*UNFREEZECODE#” (without the quotes) and insert MCK code provided to you by replacing the UNFREEZE CODE.

If you are still facing issues, enter the NCK code, press OK button and confirm. Then enter the MCK code, again press OK button and confirm. Now enter the Unlock Code carefully, your device will be unlocked.

Before you start using the phone, do not forget to reboot the device.
