Introduction
EID2
- You will new decrypted EID2 data.
- How to get it on Linux is described here: http://www.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:
IV: 00 00 00 00 00 00 00 00 key: 6C CA B3 54 05 FA 56 2C
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
- Tested on my PS3 Slim with OtherOS++.
- After writing P-Block to BD drive buffer 2, authenticate the BD drive with ps3dm.
# First enable writing BD buffer 2 sudo ./bd_enable_buffer_write -b 2 # Write P-Block to BD buffer 2 sudo ./bd_write_buffer -b 2 -i pblock.bin # Authenticate the BD drive sudo ps3dm -v sm drive_auth 0x29 # It should not fail !!! ss status 0
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.

Test
- Tested on my PS3 Slim with OtherOS++.
- You cannot just write a new HRL to BD drive buffer 4.You can actually but it will corrupt your current BD HRL.
If you corrupt your HRL then nothing bad will happen but you won't be able to play BD movies. First you have to send P-Block to BD drive, after that authenticate the BD drive and then write a new HRL. Only in this order will it work.
