if you forgot the lock pattern
if you forgot your lock code
the only way to fix it is perform a master /hard reset on the device
which will wipe all the data on the device other than what's save on the memory card
your pictures, song, videos only..
- power off the phone
- hold the back arrow,volume down key, power key at the same time
- keep holding until a black screen with yellow letters will show on the screen
- use the volume buttons to find factory reset.
- press home key to confirm
- the phone will reset back to as if it was a brand new phone
- start over from scratch
- you will need to recreate a gmail id and password. maybe you want to write it down this time.
- good luck!!
