PS3 Hypervisor LV2 (GameOS) Dump Method is Revealed!

163w ago - As promised, today JaicraB has revealed the PS3 Hypervisor LV2 (GameOS) dump method and circuit used to allow the PS3's memory to persist while booting into OtherOS, which then allows dumping of the memory.

This was apparently on a CECHG model system with board model SEM-001 1-875-384-21

To quote, roughly translated: DemonHades / JaicraB Extraction Method:

First of all, be careful if you're going to attempt this, I am not responsible.

It's about keeping the RAM alive when moving to OtherOS. To do this the ram must be fed at all times so as not to erase the data.

This area is sensitive. At that point we had settled with two resistors together. You have to remove it (remove it, but you could also cause a short circuit). It has 4 legs. At this point it tells the RAM and the integrated MOSFET turns off.

Zone B

From the point labeled we get the feed. You can put anywhere on the track.

Zone C

At this point labeled we have to make a bridge to defeat the two resistors.

The original point of the exploit.

The Technique

It is possible that the first time you start count him to do for the recovery.

It Summarized a bit with the following steps:

• Log into XMB.
• Touching, ejectura, configure, filling the memory with more information.
• Run a game, insert a BD, etc, etc.
• Then boot to OtherOS.
• Dump memory to exploit.

Remember: The first 36 Megabytes are the "privileged memory" that contains LV00, LV1, LV2. The rest is waste memory of XMB (very interesting) and data from OtherOS.

The next thing to try is to start a tiny linux system and do a full dump. So we would get more data from the XMB and less disturbed memory (from OtherOS)

The bad thing is my two-week vacation is over (I would have liked to have one more week to follow up).

Good luck to all and share!
