Vodafone firmware is called "vfe_x" where x is the region number. If you find the corresponding region (there should be at least one version in the downloads section), flash that FS using the corresponding Vodafone CDA (you can use generic MAIN). If you run SEUS after that, it'll detect a Vodafone CDA and It'll flash Vodafone MAIN and Voila, you have rebranded your phone!

And remember, you don't have to flash the latest F/W as SEUS will update anything you flash anyway.
