Default Looking for 4.1.1 stock / where the hell did search go?

Search was never good on here but I can not for the life of me figure out how to search the development forum anymore. Anyway I am trying to unlock my phone which looks like I'm going to have to downgrade to 4.1.1, unlock, and flash a nandroid backup. Does anyone know where I can find a stock 4.1.1? Much appreciated
