140w ago - A few weeks back PS3 Firmware 4.0 was released, and recently French PlayStation 3 developer UpSilon has made available a dump of the dev_flash contents for others who wish to examine it alongside a previous version below.

To quote, roughly translated: UpSilon, French developer already known to have deciphered some files on the console of Nintendo 3DS, ext today through his blog, the dump dev_flash firmware 4.00.

For information, dev_flash is a very sensitive part of the PS3 NAND which contains many key information such as firmware, the numbers of encryption running games and other programs, or other important files firmware. The dump of this part could therefore, if a developer managed to unpack, to facilitate the establishment of a CFW 4.00.

Upsilon also announced it has started working on the reactivation of the Service Mode (Jailbreak) on 3.56 + firmware.

From [Register or Login to view links]'s page: Here is a dump of the version 4.00 dev_flash.

I had previously leaked dump my firmware 3.73 (Available for download in the "[Register or Login to view links]"), but my site was still under construction and I lost much time to update it due to the time I devote to my studies (Terminal LAC) and I did not have much time was devoted to the scene.

During the holidays I am responsible, but I will try to give as much information as possible waiting for a response from Kakaroto. I shared these dumps to get the attention of developers to program an emulator we dev_flash.

For those who want to test dumps on 3.41JB with "FIRM JaiCrab Load" because you can try on my side, I used "CFWLoad 1.0" in 3.41JB (PL3). Emulation looked heavy, I could not leave the program because after a few seconds the console would have been totally blocked. I thought at first the problem was my jailbreak. However, this was not the case, because after I tried with a 3.41 dump (edit) and loading it well.

I finally concluded that the emulator should help the dev_flash home to work, for this reason that when you make a NAND emulated with SHIFT it resets everything to ultimately make a regular MAJ that will change the real dev_flash your console. Attention, the emulator does not emulate completely dev_flash stored in your USB drive. (Internal HDD etc ...).

If developers are interested in these dumps, I hope they will do something. I for my part I work on the Factory / Service Mode firmware higher than 3.56 and the Nintendo 3DS.

NO !! I can tell you from my work. Yes you can emulate but not everything is working in case of some files are only loaded douring boot up and cant be changed after it or with a cold boot.

You can do some tests and exermine it but a COMPLETE emulation over a existing fw doesnt work. And its not only dev_flash !! Some files need to be placed onto the hdd and some of them need to be placed into the flash.

You can emulate (i will say) the half of the flash but not the hdd part. Its more likely you can do some mods on files and quick test them even if your not on real FW 4.0.

Good for dev's and modders to create the first steps and parts of a 4.0 CFW

If I understand corectly this, he mean that on a PS3 in CFW 3.41/3.55 & using a hombrew which allow-us to mount a dev_flash fw image, we could load the dev_flash 4.00 = the firmware 4.00 without installing-it !! just from a USB drive !! a virtual machine !!

Like using this Jaicrab USB Firmware loader: jaicrab.blogspot.com/2010/09/ps3-usb-firm-loader_22.html

But is this really possible, was it done before !!! launching OFW 4.00 without installing-it !! it seems to be so hard in my mind, am I wrong ?
