[Duke]

hi my friend borrowed my u1 for a while, & he gave it back without saying anything wen i try to open it, Its showing too many pattern attemps, by this its evident that it got locked due to wrong pattern, but when i try to put my genuine gmail account id n password still it isn't opening, shows wrong username or password.? & wifi is turned off so how to connect to internet as no options are available except id n password

tried reset button, nothing happend how to reset it ?

It happens if too many wrong attempts are done so just wait for some hours and then try your Genuine pattern and it should unlock.
