Right now I have 2 ROP chains ready, one for idps dumping & the other for flash memory dumping. The CFW Rebug 4.81.1 is proposed 2 version REX as D-REX, the Rex is intended to consoles under CFW cex file, while the D-Rex must be install on past console or benefiting of a DEX (Firmware Development). It requires providing values/parameters & offsetting to each gadget instruction as well.įirst week of September, I joined their effort & 2 weeks later we had ROP execution.įrom that moment, I have been doing all the ROP development work alone while the other 2 helped with testing & researching (and debugging for esc0rtd3w). The principle is simple, select snippets from the system code (snippets like these are called gadgets) & assemble them so execution jumps from one gadget to the next until the task we planned is done.

Executing our own payload is made impossible by NX but we can still execute code despite NX using ROP (Return Oriented Programming).

One way or the other (by hardware or by software) after the patch has been applyed you can install a CFW 4.I started investigating the ps3 webkit about 6/7 months, but at the time, it was only to gather information, I had no idea I would eventually be the one working on it!Įnd of August, I gave the information I had to esc0rtd3w & expected he would work on it alone.

The exploit is compatible with OFW, HFW (and not sure if CFW too) of the latest versions, since 4.84 or so. the exploit hosted in the bgtoolset web initiates a process that writes the patch to your flash chip/s This requires money, time, reading a lot to learn from tutorials and the experience of other users, etc.Īnd the other way to do it is by software. so you would need to repeat the process 2 times or buy a "clip" that is attached on top of the flash chipīut in your motherboard model is more challenging because it have 2 flash chips of NAND type. To do it by hardware is required to buy a hardware flasher, and either solder a bunch of wires to very tricky points of the motherboard. You can convert a CEX console to a DEX console, if thats what youre into.

The patch needs to be applyed to the flash (a chip soldered into the motherboard), and there are 2 ways to do it, by hardware or by software Downgrading is taking whatever firmware your PS3 is currently at and in most.
