1. Take a wrong network SIM (a sim the phone does not currently accept) and insert a half of it, so when you turn on the phone it won't detect the SIM. Very important so it won't ask for network password and shows "Insert SIM" message.


2. Turn on the phone, First do a CUSTOM reset: *2767*2878# (phone may display foreign language – don’t worry !) (The last digits after the * will appear as - - - -, this is normal)

3. Now push the sim all the way in, at this stage the phone is still asking to "Insert SIM" with the WRONG SIM inside.


4. Make a FULL reset by typing: *2767*3855#


5. The phone should reboot working with "wrong" sim inside. (do not turn off the phone)


6. Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#


7. Disable network lock by typing: #7465625*638*00000000#

Your phone will now be unlocked.
