You don't downgrade to a lower firmware by simply installing over it. That can cause a brick. You would need to use a Rebug Downgrader to downgrade then go to 3.55 CFW, then QA Flag on 3.55, then you can go up to 4.70 to be safest.

Meh worked for me when I transferred from 4.70 DEX to 4.65 DEX without downgrading to 3.55 DEX but I guess downgrading is safer. Might be because you guys are talking about CEX in which case I forgot everything about CEX besides spoof.

This is only if you did not set the QA flag before. Once set you can upgrade/downgrade Rebug at will.
