When trying to enter an unlock code, the message "Phone frozen" is displayed.
In this case, you will need a Freeze code (MCK code) to solve the problem of freezing the message on your phone.
How to enter freeze and net codes on Samsung android phone on our Z3X youtube channel
MCK = DEFREEZE = Defrost - various designations for the "defrosting" code, which are necessary if you have entered an incorrect unlock code (NCK=Network Lock=PIN) by mistake and the device does not accept the correct code. This is not an unlock code - it is a so-called "reset code". After entering this code, the phone will display the message "successful" and then ask you to enter the unlock (NCK=PIN) code again.
It is important to note that Samsung phones do not have a menu where you can check the number of unlock code attempts. Therefore, if you have a used device in your hand, it is impossible to know whether unlock codes have been entered before or not.
P.S. NETWORK PUK code = freeze code.
To input the freeze code:
- Switch on the phone with an unaccepted SIM card.
- The message "Phone is frozen / SOS" appears on the screen.
- Type the unfreeze code (Nothing will show on screen)
- Press the Enter button
- The phone will ask for the Network lock code
- Enter it from your Samsung Tool software.
- The phone will be unlocked
This should successfully solve your phone freeze problem and unlock your Samsung phone to any GSM network.
