A Working Way To Restore Your Blu-Ray Playback! - Now with easy to use PHP Script!

[The Central Scrutinizer]

Finally, after alot of nights looking at HEX editors until your eyes started dreaming in HEX and tons of people working together figuring out the format of the DRL1/DRL2 files that get destoried by the downgrading process for some reason on the 256mb NAND PHAT PS3 consoles.

A confirmed way to restored your blu-ray playback has been posted in the wee hours of the morning, when everyone should have been busy dreaming of their XMAS gifts, but in a way this a special XMAS gift for all PS3 consoles!

Please note, that this is just a rough way to get you back up and running and you need to be handy in using a PC with a Blu-Ray Reader and a HEX editor, but these hard-working PS3 developers are working on building a easy tool to make the steps much more easier for all the PHAT PS3 owners waiting.

UPDATE #4: Since tons of people have been using the PHP script to fix up their blu-ray playback, you might be able to do the same if you lucky enough to own one of the same movie titles, see here for list of already ready to download titles:

UPDATE #3c: Many people have been able to restored their Blu-Ray playback by following the HEX editing steps below!

But now thanks to the helping hand that Arodd has offered he now shares with us a easy to use PHP script! Where you can upload your MKB file and it returns a custom built DRL just for you to use on your PS3! Now updated to v1.1!

MKB to DRL Script --> http://arodd.com

For this to be successful you need to take your original blu-ray movie discs you own that you have played on your PS3, and you need to find the ones with the highest MKB value and then try out those resulting DRL's on your PS3 until you find the one that you had played that in fact updated your drive! -- Read the following to try to understand the logic:

Though movies can have the same MKB version, different titles have different DRL's/HRL's and you need the title that has the matching DRL to go with the HRL currently on your blu ray drive. -- For Example:

Played Title(mkb17) = DRLa(dev_flash3)<-> HRLa(Blu Ray Drive) <- new higher mkb, so files updated!
Played Title(mkb19) = DRLb(dev_flash3)<-> HRLb(Blu Ray Drive) <- again newer mkb, so drive updates!
Played Title(mkb19) = DRLc(dev_flash3)<-> HRLc(Blu Ray Drive) <- we are already at 19, so no update!
Played Title(mkb3) = DRLd(dev_flash3)<-> HRLd(Blu Ray Drive) <- still at 19, so again no update!

If this was the sequence of movies played in order, your Blu-Ray drive would have HRLb, and you would need DRLb to restore playback. Replacing your dev_flash3 from someone elses has no impact on this requirement as the HRLb is still on your blu-ray drive.

Sadly, you still will need a PC with a Blu-Ray reader to grab the BD:/AACS/MKB_RO.inf file from the movie disc, but SnakeMar points out you can also downgrade to v3.15, install linux from this link: (Ubuntu 0.04)

And then insert your blu-ray disc, and it appear on the screen, then just navigate on /dev/cdrom/AACS/ and grab the MKB_RO.inf -- It's just another way for people don't have Blu-Ray reader on their PC!

THE FIX: Arodd's original post has now been updated it to make it clearer to follow, but PLEASE note now that easy to use tools have been released, it is only there to inform you more on how this fix works:

I updated some of the wording in my original posting making it slightly easier to understand and now that it has been restored I feel comfortable directly posting a copy of it here....

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 potentially recover your blu ray playback.

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

The DRL data from inception is now in the spreadsheet, this is a good candidate as it has one of the higher mkb versions. Let's say that The Dark Knight was the highest MKB version that your PS3 has seen, then 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 10 03 00 00 00 09(mkb version in hex) -- The Dark Knight (12 bytes) 0x09 -> MKB9

Then the HRL is listed....

21(HRL) 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 (0x6c = 108 bytes)

Following the HRL the actual DRL data begins.

20(DRL) 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 (0x34 = 52 bytes)

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.

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 updated your drl and that will give you the method to restore your playback. Most won’t have to try too many DRL variations until finding the right title.

Others are (0x3c = 60 bytes)

10 00 00 0c 00 04 10 03 00 00 00 13 20 00 00 3c 00 00 00 01 00 00 00 01 03 e7 00 00 00 00 00 01 93 78 15 97 ad d4 32 7b 90 7f 5b b7 f2 b2 e7 99 d9 ee 28 11 8c b5 4a f3 c1 fe 35 56 bd bf 9a db 38 7a 29 49 d4 87 ba 01 -- Inception (0x3c = 60 bytes) 0x13 -> MKB 19

If you have MKB files from titles not on the spreadsheet and aren’t comfortable extracting this data yourself. Add a download link tempfiles, rapidshare, putfile, etc. to the spreadsheet with the movie title and I will grab the data and update the spreadsheet. Also if you find the hex for your title, please update the spreadsheet to help some others who may have used the same movie and don’t have a BD drive or the skills to produce it themselves.

I followed arodd's example.

I took my latest blu-ray disc and copy the MKB_RO.inf file from the AACS folder.
Open the file in a hex-editor.

I compared my blu-ray title against, arodd's blu-ray.

In my case i had 21 00 00 84 (record length). took "hex 84" and converted it to dec in the win7 calculator and i got the value 132.

After that its time to count from the value 21 00 00 84 (1 2 3 4 to 132), 21 is equal to 1 etc.
After this first calc, you go to the next step. Look into the MKB_RO.inf file .

The next i converted, in my case it was 20 00 00 3c (record length). 3c in dec is 60.
20 00 00 3c 00 00 00 01 00 00 00 01 03 e7 00 00 00 00 00 01 25 7c 86 19 67 43 32 0e 8f 09 66 d1 6b a6 08 77 b4 c9 20 79 71 4e 69 92 bb 35 0e 79 04 b5 75 2a ff 7d b1 13 d2 4e 40 5b

arodd have explianed it pretty well in his post.

Damn, so there is no way to do this with a PC without a BD-drive? My PS3 only played 1 BD, the James Bond Casino Royal that came with the console. So if i could get my hands on the complete DRL of this particular movie, I wouldn't need a PC with BD-Drive, right?
Thank you, kalle71!

EDIT: I added your DRL-line to the spreadsheet

"Merry christmas, one small clarification, for all the people does not have bluray drive in pc, how can we solve for those people, pls suggest is there any other easy way for restoring bd movie playback, does this work in 40gb ps3 console, i m based in india"

a lot of later pc dvd drives have also the ability to read BD discs. Don't know if it will work but you can give it a try

[steplay29]

just wondering guys would this work if you dont have a blu ray player on your pc.download the blu ray of your desired film and run it through a blu ray player virtual disc on your pc to extract the file you need?

ps forgot to say many thanks to all you guys out there who worked on this.guinness for u all if ever in ireland lol.

[pablo_jre]

Wow, quite a complex way of fixing it. Ingenious though!

Why did Sony design the PS3 (or blu-ray playback for this matter) in this way?

Why am I on the internets on Christmas!?

Merry Christmas all ye good people. And Merry Christmas to the dicks too.

[KaISeR SoZEi]

it's complex but very clever !

In order to make it quick and safe to do, we need someone to make a little apps that extract MKB_RO.inf from the BD we played last and restore drl file automaticaly ( it can be done easily by someone even with a very little coding skill )

i never seen a bluray film on my ps3, but i downgraded and i lose bluray playback, i didn't done dev_flash3 backup, so now i have only a backup of already broken bluray playback (attached below and already sent to devs)

i'm really sorry because i know that ps3 with zero playback is "special" for you

can i restore bd playback with a random bluray film? (i have no ps3 access until 10th January)

[Incognitus]

it's a real genuine Christmas miracle!
