Okay Figured it out. Just in-case anyone else has this issue in the future you have to go to /System/Library/Carrier Bundles/iPhone/ and get the old bundle which was named Vodafone.nl and place its contents in /private/var/mobile/Library/carrier Bundle.bundle. That downgraded my carrier version from 11.3 to 11.0. Luckly I had an iPhone 4S also for Verizon which wasn't updated to pull the bundle from.
