iPhone with password was locked

[zvezdochots]

Hi everybody!
I have set up a password on my iPhone. Then I forgot it. I remember that my password consists from 3, 4, 6 and 7. Now my iPhone is locked and I have one attempt to enter password every 30 minutes. What should I do if I won't remember my password? How can I completely reset my iPhone?

DFU restore with iTunes.

Is Find My iPhone enabled? If so, log into iCloud and wipe it remotely. Then enter your iCloud credentials and restore it.

Start by eliminating the numbers that definitely aren't in your password and go through the permutations systematically. You can probably figure it out in less than a year, by my calculations. Get started.
