Default [Q] Flashing stock KitKat

Hey everyone

So I am having a problem flashing KitKat to my phone.

I was on B120 CN and then flashed to CM10.1 and everthing has been great. Now I want to flash to Kitkat so I can test OmniRom 4.4.2.

So now I have flashed back to B120 CN stock but I can't seem to get it to update via dload/Update.APP

I am using the B118 Recovery so I am not sure if I have missed something and that I need a new KK recovery?

Any help is much appreciated
