If it is true,it is really a good news to many guys,someone released the solution to solve the BluRay problem when you use the PS3 break, E3 card reader,P3Go,PS3 game HDD do the downgrade.They reported that the reason is the issue was the loss of the DRL1/DRL2 files when the PS3 was downgraded. And also released a solution too .
Notice: this method is complicated and need more tests to prove it , so take care before you decide to try it.
The method 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.
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."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.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.”
As i have said ,this news still need more info to prove it. we will keep focuse on the update news and send the news in time.
