G510 Unluck Forget Patern Look

If the handset is locked by the pattern code you can try to enter the username and password for the google account to unlock it, or else you can try to enter the username for the google account and try to enter the password as "null" or else the last option is to reset the phone which will delete all the personal data from the phone but it wont delete any information stored on the micro sd card The procedure; turn off the phone >press and hold the volume up key , the calling button and the power key together at the same time >(you will get a black screen with the android system recovery options) first select >wipe data/factory reset then select >yes- delete all user data (wait till the data wipe is complete) then select >wipe cache partition wait till the cache wipe is complete and then select >reboot system now and the handset will reboot and unlock.
