I see some comments wondering about the SDXC update so I'll just let everyone know my experience.
I have a launch system (1.0.0) that I had updated through 4.0 and wanted to leave it there for HB. Until then I was using a 32GB SD card which filled up, so I bought a 256 SDXC. After inserting to the system it prompted me for an update. Knowing there was an SDXC patch I ran the update, but it actually also performed a FW update to 4.1.0.
So regardless of version, if you didn't have the SDXC driver the system will perform a full FW update to apply the SDXC driver.
