    Rumor: PS3 "Phat" BluRay Compatability Restored

    UPDATE: I received the following PM earlier today:
    I've been working with Hi3 and the rest of the crew at #ps3bluray on Efnet and it's urgent that the story about bluray playback problem being solved be removed because the research is not even CLOSE to final and the person who released the information was not authorized to do so. If you need to you can contact hi3 or myself on Efnet #ps3bluray
    So its not finalized yet and you should proceed to do this at your own risk. According to hi3, "If the traitor system is triggered it could lead to drive/host revocation en-masse in the future."

    Well a great gift this morning to the PS3 scene, as arodd of PSX-Scene has managed to restore Bluray again to "Phat" PS3 models that were lost @ time of downgrade (the issue was the loss of the DRL1/DRL2 files when the PS3 was downgraded).


    The current method, posted below, is a bit complicated and requires the knowledge of how to use a PC with BluRay reader and HEX editor. You can however expect an "newb friendly" tool in the future though.

    To quote:
    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.

    https://spreadsheets.google.com/ccc?...en&output=html

    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.

    Only ever played the demo

    The only Blu-Ray Disc I ever played in my PS3 was the Demo BRD that came with it, I would bet that there are a lot of people in the same boat and have never played any other.

    I think a lot (if not all) of fat ps3 owners with 256 mb Nand Flash so BD playback problem after downgrade know a PS3 in jailbreak mode will not play BD discs. If that was the whole problem the scene didn't need a couple of weeks to sort that out.
    P.S. to much smilies makes a post difficult to read ..
    ---------------------------------------------------------

    OT: I'm glad the scene found the solution again. Sony was hoping the problem would stay so less people want to downgrade but to bad for them :thefinger:
    Never underestimate the power of the PS3 open source devs !!

    this is all good but see i updated it to 3.55 a while back in hope that the update would restore it and it didnt so im stuck without BD playback and cant downgrade. I guess my mistake but it was way back before downgrade was even possible. I was one of the first people to report playback disabled after using JB on a phat model. Sucks.

    check that link as it seems the guy that released it was just a tester , who didn't fully understand the problems it could cause.
