Unlock android phone with forgotten password and attached gmail account details too Unfortunately My android phone Sony Xperia Go with got locked. I gave this to a friend for use and he gave this to his friend. Now the problem is no one have any idea which gmail account is linked to this. Neither any one is taking the responsibility... well that's other problem.

I am writing here for help. If anyone can help in this.

The phone is not allowing to enter pattern now. It is asking for gmail account details or security question answer and don't have any of these.

I hope anyone could help me this.
If you don't worry for the data of your phone the everything will be easier.First of all turn off the device.Then open it again, wait 3 seconds and then press the power button and the volume up or down(the reboot may differ from phone to phone) Then, at the reboot you will be able to use it only with the up and down volume buttons.Reset the phone and everything will be deleted (even the password) For more information check here : http://www.greenbot.com/article/2458403/how-to-perform-a-factory-reset-on-your-android-phone-or-tablet.html
