Since the release of Tical’s task for ps3mfw builder we have seen several mfw that have been released with cinavia patched out.  Well now you no longer have to leave your favorite firmware to enjoy that option. Codename: Rebug has released a handy little .pkg to do that for you. Remember this is unnecessary if you are already using any of Rebug’s firmwares.

Disable Cinavia Installer for 3.41 and 3.55 CFW/MFW will permanently install the necessary ‘Cinavia Free’ video modules (excluding AVCHD/Blu-ray) to your PS3.

This has been a feature of the REBUG firmware from the start but since there seems to be a lot of interest by users of other CFW/MFW we thought we would make an easy installer for everyone.

PS3 hacker tical has managed to disable the annoying Cinavia DRM protection on the PS3 console. In short he basically found the files on the PS3 responsible for the checks and patched them. The file he released is known as change_cinavia_files.tcl for the PS3MFW builder – allowing you to create your own modfied firmware with the cinavia patch.

Currently the fix only works for DLNA playback and copying and is still being worked on for AVCHD and BD playback.

To quote:

I have traced the Cinavia DRM checks to 4 separate sprx files and after a long time trying to patch these files I have found that 3 of those files are present in the DEBUG (DEX) firmware don’t have the Cinavia DRM checks enabled. Files are videoplayer_util sprx, videoplayer_plugin sprx and videoeditor_plugin sprx.

I have successfully copied these 3 sprx files from DEBUG (DEX) FW 341 over to my retail PS3 unit running OFW 341 using dev_blind and Cinavia seems to be now disabled. I’ve confirmed this by playing back a number of Cinavia affected video files.

This means that Cinavia is now disabled for all DLNA playback and copying, but Cinavia checks on AVCHD and BD playback are still present with Message Code 3 that mutes the audio as the sprx file with the Cinavia check bdp_plugin sprx is not present in DEX firmware because BD playback is disabled in DEBUG. If someone is able to patch Cinavia out of bdp_plugin sprx this will be solved too.

I have created a new task for PS3MFW so this can be easily made part of any new MFW’s as needed. Any FW version that has had the DEX firmware leaked should be able to be used to create a CFW of the same version. eg DEX 3.41 -> MFW 341 or DEX 355 -> MFW 355 etc etc. Don’t use sprx files from different FW versions! See git hacks for change_cinavia_files task source.

Big thanks to the KaKaRoTo and REBUG team for their community contributions as this would have never been possible without the knowledge they’ve shared with us.
