The site Ps3DevWiki continues his research on the True Blue and gives us today the payload.

This new dongle allows for recall reading backups 3.6 and higher disk drive and Blu-Ray burned, but it has an access control to ensure its presence in the custom firmware 3.55 otherwise the special features are disabled. The secret of this dongle is the use of debug eboot, it would not be a big step forward and could be countered easily. The payload of the True Blue has yet to be decrypted before it is used on USB dongles ( Teensy example, E3 Card Reader, PS3Key). Whitezilla Thanks for the information. Homepage: http://ps3devwiki.com
