decrypting the firmware upgrade files

Is there any information about the firmware upgrade files for the orizon and the odyssey? I want to have a look at the files inside them and was hoping there was some obvious way to decrypt them

The files (CybUpdate.bin) start with the string 'Boo1' and end with 'GAME OVER', but otherwise I didn't discover any patterns in the data. There are no text strings and it's not very compressible (with bzip2 they actually become bigger). I looked at the firmware upgrade files from both devices and besides the header and the footer I didn't see any similarities in the data.

Does anyone have access to the file system to figure out how the firmware updates are done?
