If you, like me, prefer to stay on 4.46 and not to update, you wont be able to watch recently bought blu ray movies.AACS (Advanced Access Content System) is a copyright-protection technology that is used on Blu-ray movies.
The copyrighted content is protected by setting an encryption key on both the disc and the device used to play the disc.
An AACS encryption key expires in 12 to 18 months and must be renewed.
You will be greeted with a message like this :
(Translation: To play this BD, you must renew the encryption key. Perform a system software update to renew the encryption key.)
What you need:
* Playstation 3 Console on Version 4.46
* Playstation 3 Update 4.50 PUP File for CEX/Retail (everything lower than 4.70 can work, not 4.70 tho)
* pupunpack, depkg, unpkg or similar tools for unpacking updates
* Multiman, dev_blind or similar tool for ftp, accessing dev_flash
* scetool or similar for decrypting, resigning
* and skills to use them
What we will do:
The "key" (literally) lies within a file called "AacsModule.spu.isoself".
We need to resign this file from Update 4.50 for 4.46 and replace it on the console.
Preperations
Get a hold of the PS3UPDAT.PUP of Firmware Version 4.50.
(MD5::E3DECAF8BEEF0ABC8F7999F66DE05AF9, SHA1::2F879E594841CD0821CDF55AD049AAD864EDEB89)
Make sure you got all necessary information for decryption inside data/key-file for scetool, namely:
[isoldr]
type=SELF
version=0004004600000000
self_type=ISO
revision=0001
(...keys...)
[isoldr]
type=SELF
version=0004005000000000
self_type=ISO
revision=0001
(...keys...)
Step 0: Unpacking
Use your favourite tool and
* unpack the PS3UPDAT.PUP
* extract "dev_flash_022.tar.aa.2013_09_14_050612" from "update_files.tar"
* decrypt "dev_flash_022.tar.aa.2013_09_14_050612" and extract "/dev_flash/bdplayer/AacsModule.spu.isoself"
Step 1: Decryption
Locate the just extracted isoself module and decrypt it using scetool.
Code: Select all
Decrypt Command:
scetool --verbose -d AacsModule.spu.isoself AacsModule.spu450.elfscetool 0.2.9 <public build> (C) 2011-2013 by naehrwert
NP local license handling (C) 2012 by flatz
[*] Loaded keysets.
[*] Loaded loader curves.
[*] Loaded vsh curves.
[*] Using keyset [isoldr 0x0001 04.50]
[*] Header decrypted.
[*] Data decrypted.
[*] ELF written to AacsModule.spu450.elf.
Step 2: Resigning
Unlike game selfs, isoldr elfs need to be signed specific for firmware version and are not interchangeable simply by replacing.
* Start up Multiman and your ftp program
* Get yourself a hold of your original "/dev_flash/bdplayer/AacsModule.spu.isoself"
* This can be a good backup incase of problems, and we use it as template
* Rename the copied file on your Computer (not Console!) "AacsModule.spu.isoself" to "AacsModule_446.spu.isoself"
(Alternative: Get a 4.46 PS3UPDAT.PUP and decrypt it like in step 0 to get a hold of its file.)
* We will now resign AacsModule.spu450.elf.
with AacsModule_446.spu.isoself as template to a new AacsModule.spu.isoself.
Code: Select all
Resign Command:
scetool --verbose --template=AacsModule_446.spu.isoself --sce-type=SELF -e AacsModule.spu450.elf AacsModule.spu.isoselfscetool 0.2.9 <public build> (C) 2011-2013 by naehrwert
NP local license handling (C) 2012 by flatz
[*] Loaded keysets.
[*] Loaded loader curves.
[*] Loaded vsh curves.
[*] Using keyset [isoldr 0x0001 04.46]
[*] Template header decrypted.
[*] SELF built.
[*] Data encrypted.
[*] AacsModule.spu.isoself written.
Make sure it is using the isoldr keyset for Version 4.46, the target system.
Now we will only have to replace this new file on the system.
Step 3: Replacing
* Start up Multiman incase you didnt before
* Enable "writeable "dev_flash"" in settings column (it is usually the 4th least option)
* /dev_flash will now become available for replacing files, mounted as /dev_blind
* Overwrite older "/dev_blind/bdplayer/AacsModule.spu.isoself" with your newly resigned isoself (Remember: /dev_blind not /dev_flash !)
* Exit Multiman
Step 4:
* Insert your BD Movie and watch it. (tested with MKB v47)
