SC Live 4 Engine DJ OS 3.0.0

I'm looked at the Denon SC Live 4, and it now looks like Denon started signing their firmware images and using sha256 rsa2048. :(

Guess they're using a newer processor with u-boot, and decided to do things the right way.

Just wanted to share in case anyone was interested, or sees something I missed.
