Have you ever forgot your android lock pattern or password??
Wanna hack your freinds mobile???
Many of people would tell you to format phone to reset password.
But a good Working solution is here.
Now connect your android to PC via Usb Cable.
open command prompt.
check following command:
“adb devices”(type all mentioned command without double quotation)
Now output should be something like alphanumeric string
eg:0123456789ABCDEF(may be different)
That means device is connected.
Now You you have to enter the system to delete password /pattern file.
