What should I do if I forget the Nokia mobile phone lock code, the mobile phone lock, and the formatting forgets the lock code?

I changed the lock code today. When I used the lock code later, I remember that I entered the modified lock code. However, an error was prompted, and the default 12345 error was entered, after a few more attempts, the system is suddenly locked (only five attempts can be entered ).

Finally, I found that I set a 6-digit password with a default password of 5 characters. However, when I entered the password, it identified a single digit.

At last, I removed the last one and unlocked it!

 

Hope to help the person who found this post!
