How do i reset the pattern lock on my cell phone if my google account and password dont work

Hi Sheena

If you forget your pattern:
1. After you fail to unlock the screen in pattern for 5 times (4 dots at least), there will be a text sign of "Forgot Pattern?" appeared on the lower-right of the screen.
2. Tap "Forgot Pattern?" and then enter your Google account and password saved in this phone to disable pattern lock.Note: If you do not log in your Google account or the device is not connected to internet before the phone is locked, you will need to perform factory data reset in DROIDBOOT mode to solve this problem.

If you forget your PIN or password:
1. To reset your PIN or password, you need to in advance log in your Google account in your device and have your phone connected to Internet as well as Location function enabled.

Do you want to get all your contacts back?
If not then just flash stock rom into your device using ODIN. You will get your phone into working condition but will loose your contacts and messages if they are in the phone memory.

Your's is an Android mobile phone I believe.

For Andorids with the Pattern lock, if you try the wrong pattern 5 times, you are given the option to use your Gmail account to unlock and reset your Android device unlock pattern.

Once you get the prompt for the Gmail login, use the account that you have set up in your Android device. This would take you to the option of resetting the unlock pattern.

Please note that if you have set up the 2-step-verification for Google accounts, your password will not be the regular Gmail password. You'll have to generate the authorizing password here: https://www.google.com/accounts/IssuedAuthSubTokens

Hope it helps. If so, please consider rating this solution.

Get your account password wrong 5 times and it will ask you if you forgot your password at the bottom. Then it gives you the opportunity to unlock your phone using your Google account credentials.

the only way I know is to master reset it, create new google account or use the previous one to activate it.

It is an Google account registered phone i believe. Then when you try wrong lock patterns a few number of times it will prompt you to lo-gin using your Google account and you can access the phone through that.

If you have also forgot the Google account and password details then only authorized service center can reset its memory and get it working

try password as "null"

format the phone... download the firmware frm the HTC site and follow the instructions
