This might be a special Christmas gift to the PS3 CECHA to CECHG (“phat” large NAND flash) systems owners as arodd has found a way to bring back the ever wanted Blu-ray playback functionality on their consoles. Honestly, i have no idea what arodd has been talking about as i am no downgrader myself but i am sure you guys can figured it out easily.

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.

DRL Reversing – Project #PS3bluray

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.

kalle71 has confirmed that the method above do work on his phat PS3 console.

Nice it’s working. My bluray is up again.

I did it in two step first i replaced the DRL1 and DRL2 and it was not working, then i put my ps3 phat i servicemode and reinstall the 3.41 system and switch the DRL1 and DRL2 and the blu-ray was back.

I follow the guide and replaced the DRL1 and DRL2 with the info from my latest blu-ray disc.

EDIT1:

hi3 (Dec 25 2010):

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.

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.”
