How do I downgrade my iPad 3 from 7.0.4 to 6.1.3?

My iPad got stuck in a loop and I was in need to restore it, which updated to 7.0.4 and it's moving slower than usual, some features of iOS 6 are missing and I kinda liked those, the look of it, etc. I've tried with iFaith but it says it's not compatible with the iPad 3 SHSH blobs. Does anyone know any method of downgrading iPad 3 from 7.0.4 to 6.1.3?
