[Q] [Help] Xperia z3 forgot pattern! topic

Hi guys, forgot my pattern password on xperia z3 D6603, tried to login with google account but it says - wrong id or password. My phone is not rooted, USB debugging off. I tried to run into flashmenu with volume down/up and power buttons - phone just turns on normally. Sony PC Companion doesn't work either. Any solutions for this?! :(
