The question was: has anyone tried to decrypt /dev_flash[2|3] using HDD decryption method? I have seen data descrambled and rebuilt with this tool - /dev_flash was nicely readable but from certain point it was scrambled (encrypted)? What I propose is to take those scrambled data and have the PS3 they were taken from attempt to decrypt them as if it was part of the HDD.
Also on another topic: it seems (almost) every storage place has been made readable but nobody found where BD-J is implemented (so far no traces of java, jre, bd-j, *.jar, ...) . Any guess?
