From GaryOPA: We received an 'an0nymous email' from some random one-time dropbox, containing a weird little attachment, with a simple note:

Program: metldr838exploit
Author: Unknown
Usage: Unknown
Reason: Unknown

Before posting we had one our PS3 crunching developers look it over, and it seems to be a set of 'C' code and headers and an compiled ELF and SELF that exploits the 'chain of trust' to dump an 'unecrypted' version of your PS3 'metldr'.

How to Load METLDR in SPU Isolation Mode on PlayStation 3

How to Load METLDR in SPU Isolation Mode on PlayStation 3 1000°
259w ago - Just over a month ago the PS3 Hypervisor lv2 (GameOS) was dumped and GeoHot hinted that it was accomplished by commanding an SPU to load METLDR.

Today dondolo let us know that simone has detailed how to load METLDR in SPU isolation mode on the PlayStation 3 and included some source code.

While this is definitely a step forward, he still doesn't specify what the read/write u32 functions are... or which functions to add to the recent XorHack release.

Those interested can check it out below, and to quote:

"After some experiment I succeded to load METLDR in spu isolation.

You need geohot's exploit to do this, because you need to turn spu relocation off (MFC_SR1[R]=0) and not let know the HV you are using a SPU (so no calls to lv1_construct_logical_spe or similar). For some strange conf, it doesn't work in HV way."
