Sponsored Links
152w ago - Following up on his Guide to Remarry PS3 Blu-ray Drives to other consoles, today PlayStation 3 developer Mark Webber has shared another on how to recover Blu-ray drive playback on 256MB FAT PS3 consoles.

To quote: Ok, so finally....

How To Recover BD Playback On 256meg Fats

  • You will need to QA flag your PS3
  • IF you are on 3.55: Using the special 3.55 downgrade PUP by Jaicrab, then down again to 3.15 or 3.41 using stock PUP files
  • Follow this guide to QA flag your PS3

By ps3nemesis: (EASY QA FLAG INSTALL)

NOTE BEFORE YOU ATTEMPT THIS OR ANY MOD TO PS3 FILE STRUCTURE PLEASE BACK-UP YOR dev_flash 2 FOLDER AND THE WHOLE OF dev_hdd0/home AS THIS IS WHERE YOUR PSN / DLC/ PSONE LICENCES ARE KEPT. ALSO MAKE AN EXTRA BACK-UP OF dev_hdd0/home/act.dat .

PLEASE ALSO BE AWARE THAT SOME PEOPLE ARE STATING THAT THE TROPHY SYSTEM GETS MESSED UP !!! FOOLS RUSH IN...

Note: Only works on Otheros++ 3.55 or 3.41 CFW at the moment, so you'll have to reflash to it, then go back to your cfw's (i.e 3.55 CFW > Otheros++ > QA Flag > 3.55 CFW )

Requirements / Installation Instructions:

  • [Register or Login to view links]
  • Rename it to PS3UPDAT.PUP
  • Install the firmware
  • [Register or Login to view links]
  • Install the qa_flag.pkg
  • Then run the qa_flag program
  • If you hear a beep, it worked.
  • Restart ps3
  • Go to network settings (Do not enter it) and hit or hold L1+L2+L3+R1+R2+down on the dpad
  • QA auto flagging is now done
  • Turn on the 'system update debug' in the debug settings
  • Play a BD disc with the highest MKB version you can get..Latest release from Blockbuster or whatever.

Note: It may start to play and then you get no video output to the tv. This happened a few times to me. Just power off, accept the "naughty boy" messgage from Sony and try again until it plays.

If it keeps doing this, you need to change to AV or component leads since your TV seems to not be 100% HDMI/BD compliant. I have tested this on several (at least 5) PS3's with 100% success rate.

Fixing DRL and CRL Hashes Tutorial by Glevand

Introduction

It's a small and easy guide (via ps3devwiki.com/wiki/Fixing_DRL_and_CRL_Hashes) how to fix your DRL/CRL issues on GameOS with PS3 Linux.

Tools

You need my latest ps3dm tool with VTRM commands retrieve and store_with_update.

ps3vuart-tools: gitorious.ps3dev.net/ps3linux/ps3vuart-tools

DRL and CRL Hashes

DRL and CRL SHA1 hashes are stored on VTRM FLASH region. First 20 bytes are SHA1 hash of DRL. Then following 20 bytes SHA1 hash of CRL.

Read current DRL and CRL SHA1 hashes from FLASH using VTRM service:



Write current DRL and CRL SHA1 hashes to FLASH using VTRM service:




If you write wrong hashes intentionally then you won't be able to play BD movies and you will get the following message:



How to get correct DRL and CRL hashes:




Test

  • I intentionally wrote wrong DRL and CRL hashes with VTRM service store_with_update.
  • After that i couldn't play my BD movies on GameOS.
  • Then i wrote correct hashes again and BD playback is working again

EID2

You will new decrypted EID2 data. How to get it on Linux is described here: (ps3devwiki.com/wiki/Spuisofs#Dumping_EID2_Key_with_spuisofs)

EID2 contains encrypted P-Block and S-Block. To get decrypted S-Block and P-Block first you have to decrypt EID2 with EID2 key and IV and then decrypt the blocks with DES-CBC. P-Block and S-Block DES-CBC IV and key:




Writing P-Block

  • P-Block is stored in BD buffer 2.
  • BD buffer 2 is of size 0x60 bytes.
  • P-Block is in decryoted EID2 at offset 0x20 and of size 0x80.
  • Not all P-Block data is sent to BD drive. Only data starting at offset 0x10 and of size 0x60 bytes is written to BD drive buffer 2.

Test


Writing S-Block

  • S-Block is stored in BD buffer 3.
  • BD buffer 3 is of size 0x670 bytes.
  • S-Block is in decryoted EID2 at offset 0xa0 and of size 0x690.

Writing New HRL to BD Drive

HRL is stored in BD buffer 4. BD buffer 4 is of size 0x8000 bytes.
glevand@debian:~$ sudo sg_read_buffer -i 4 -m 2 -o 0 -l 0x8000 -r /dev/sr0 | hexdump -C
