Go to the N78 area of Saipan Forum to download a software called Advanced Program Lock (you need to register Saipan account), which must be installed on your mobile phone, not in your card, and then set it up. Remember that the initial password is 1234.

I used 78, and I also installed that software.

You may need to sign your name. If it can't be installed, I suggest you crack the phone. After cracking, everything can be loaded. Cracking has no effect on mobile phones.

Go to the forum more often, there are many good things on it.
