Shsh blobs are device-specific, and once you upgrade to a newer firmware, unless you've got yours saved, you're screwed. You cant forge shsh blobs. So unless youve got shsh blobs for a lower firmware saved, you're stuck on 4.2.1

I've heard rumors one or more of the dev teams is working on a way to bypass this shsh blob thing - but then again it's just a rumor, so probably untrue as there are plenty of rumors out there about this sorta stuff
