gmail and password lock after pattern lock

[AC Question]

A little boy got ahold of my HTC One M7 and swipped the pattern too many times and the phone is now asking for gmail user name (which I dont remember)and password. I know the password but do not remember enough about the username to be able to retrieve it. I can not loose the information that is on this devise!!! I need to hack into this devise. I have all that is neccessary to prove that I am the owner of the device.

You need to contact Gmail to get your credentials straitened out first. Then you can get back into your phone.
