What I basically need: I want to access recovery(or bootloader, I am not sure what its really called) to do a factory reset.
History of the problem: My little sister entered the pattern incorrectly too many times and now the phone is locked asking for gmail and password. Although I know it, but the phones wifi is disabled, so it says "wrong username or password" and hence I can not unlock it. I want to do a factory reset via the recovery but the phone is not going into it even though I press volume down + power(I also tried the volume up). USB debugging is off, and the device is not rooted... please help me, how can I get around this damn problem?
