Joyeux noël ! Voici une solution pour ceux qui ont perdu la lecture des films en BluRay sur leur PS3 depuis un downgrade.La méthode est pour l'instant très complexe mais pourrait être simplifiée dans le futur.
Edit: Cette méthode est très risquée et n'aurait apparemment pas du être publiée car il s'agit de bêta tests dans le but de fournir au final un outil automatique. Ne faites donc pas cette technique et attendez l'outil SUR.
Ho ho ho, des blurays sur le sapin
Pour rappel, les PS3 fat avec une mémoire flash de 256Mo (donc normalement pas les slim) qui sont downgradées ne peuvent plus lire les films au format BluRay. Le problème se situe au niveau des fichiers CRL1/CRL2.
Voici la méthode pour retrouver la lecture de ces films, en utilisant le fichier CRL présent sur le film le plus récent lancé par la console.
There is now a *hacky* method of doing a safe downgrade for users who don't have the ability to do a backup of their drl files. This method can also be used to fix a ps3 with broken playback if you know the newest disc your ps3 has played.
If you go out and rent Inception(high mkb) and play this in your ps3 before downgrading this spreadsheet will be updated with the hex values of the DRL files to recover your blu ray playback.

I don't have the DRL data from inception yet, but this is a good candidate as it has one of the higher mkb versions. Once I get it I will add it to the spreadsheet. Let's say that The Dark Knight was the highest MKB version that your PS3 has seen, than the below data would be used to restore your playback.
We have found out that the mkb from the title that updated your drl files can be used to restore your playback completely. The MKB data is located inside BD://AACS/MKB_RO.inf; If you use a PC BD drive from windows, mac, linux, etc. You can extract this data. We are working towards a method of doing this from the PS3 directly, but so far it appears GAMEOS may be blocking this file.
If this file is opened in a hex editor the beginning of the file contains the Type and Version record...
ie: 10 00 00 0C 00 04(mkb version) 10 03 00 00 00 09 -- The Dark Knight
Then the HRL is listed....
21 00 00 6C(record length) 00 00 00 07 00 00 00 07 00 09 FF FF 00 00 00 0B 00 00 FF FF 00 00 00 16 00 08 FF FF 00 00 00 21 00 03 FF FF 00 00 00 35 00 04 FF FF 00 00 00 4E 00 03 FF FF 00 00 00 54 00 03 FF FF 00 00 00 5E 2B 73 F1 7E 29 D4 04 7D 74 84 21 1E 3F 35 42 FE EB 3E B9 B1 63 B9 57 7D 86 AF F4 1A 02 A9 33 61 96 51 5A 67 0A 27 5C 8A -- The Dark Knight
Following the HRL the actual DRL data begins.
20 00 00 34(record length) 00 00 00 00 00 00 00 00 44 8F F5 FA B4 79 A3 FD FC B9 92 01 35 5C 21 3B D9 8C D3 20 06 B0 76 B5 46 92 1E 46 52 16 EE A5 5D 1E 7B 2D 02 C7 6D 0A -- The Dark Knight
Combining the Type and Version Record with the DRL data gives you the hex contents of the proper DRL1/DRL2 files if this disc was the highest mkb version your ps3 has seen. This is called a Partial MKB.
IE: 10 00 00 0C 00 04 10 03 00 00 00 09 20 00 00 34 00 00 00 00 00 00 00 00 44 8F F5 FA B4 79 A3 FD FC B9 92 01 35 5C 21 3B D9 8C D3 20 06 B0 76 B5 46 92 1E 46 52 16 EE A5 5D 1E 7B 2D 02 C7 6D 0A
The above hexed over your broken drl will restore your playback. This isn't surefire if you've played another movie that is higher than inception or have updated your drl with a different movie that is the same mkb as inception. All in all you just need to know which newest disc you have played and that will give you the method to restore your playback.
FYI: Merry X-Mas! This is a gift to all! Thanks to HI3 for doing all of the leg work in understanding the different record types.
Une méthode plus simple / automatique devrait venir prochainement (espérons le).
