Debrand Vodafone K770i

[omar8]

Hey, I bought a UK K770i from Vodafone on Pay and Talk.
At first I Unlocked it using a guide but now I want to remove the Vodafone firmware. The problem is that Vodafone do not seem to sell the generic phone so when I put the generic firmware it does not correspond the buttons (I have attached an image showing the difference in buttons).
is there anyway to use the generic firmware but set the buttons to work how they work in the Vodafone firmware?
