how do i change pin number

Solution
Can't be done. You put it there to protect your personal information and data and that's what it's doing. The best you can do is take it back to factory settings and start again - preferably without a PIN.

Turn it off and press the Volume Up button while turning it on again. A menu will show up and you choose by scrolling using the volume up and down buttons and making your selection using the power button.
