How can I get into my one S?

[Guest Tom Kitchen]

So i managed to forget my pattern unlock after i changed it and lock myself out of my one s to the stage where you can only sign in with your google account. However for some reason this isn't working properly (data and wifi are turned off so maybe because it needs to connect to the google servers). What happens is i type in my googlemail and password and i click sign in, and it just clears the password field and nothing else seems to happen, occasionally i see a connecting message for a split second but it goes away pretty quick.

So I looked online and there are suggestions that the way to get round this problem is to do a hard factory reset. Booting holding volume down should bring me to the bootloader says google... but what i see instead is the soft buttons flashing on and off then it just boots normally.

Does anyone have any ideas, with or without a factory reset, though without is obviously prefrerable.
