DRL and CRL Hashes

  • DRL and CRL SHA1 hashes are store in VTRM FLASH region.
  • First 20 bytes are SHA1 hash of DRL. Then follow 20 bytes SHA1 hash of CRL.

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

sudo ./ps3dm -l 0x0 -p 0x1070000034000001 vtrm retrieve 0 | xxd -c 16 -p

00000000000000000000000000000000

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

sudo ./ps3dm -l 0x0 -p 0x1070000034000001 vtrm store_with_update \
    8f0652bc6162a240362f90f1b2e5405bb82ee50296791f41f9a76f4d895dd5820db108ec03d19250

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

Playback of BDs is prohibited on this system.
