Creator of the DARKNET brand of PlayStation 3 CFW developer darkjiros is back with an update to the Cinavia Protection Tool for v4.81 Support, this tool is needed for both DARKNET 4.81 Standard & Cobra Custom Firmware builds, as there was an issue in the encryption causing a "800299D2" error code to display when attempting to play your personal backups of your BD/DVD media.
This tool solves this issue and relieves this bug present in v1.00 of both DARKNET flavors. Also note this can be used on all 4.81 CEX Custom firmware to disable Cinavia Protection.
