It seems some talented dev behind the DS scene is interested on the ps3 and has been hard at work by dumping the dev_flash of the 4.0 firmware… thats right guys you heard it right UpSilon managed to dump the dev_flash contents for other to have a look, here is a rough translation of what he had to say:

Here is a dump of the version 4.00 dev_flash
I dump my earlier leaked firmware 3.73 (Available for download in the ” Download “), but my site was still under construction and I lost a lot of time to update 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 for 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 do 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.

Also a dump of 3.73 for those interested
Download 3.73

Another homebrew app has been released that mounts a writable dev_flash. The great thing about this one is that it supposedly works on all firmwares. This will save alot of time for people wanting to modify their flash files since they will no longer have to run the AsbestOS installer. More and the source below:

!!DISCLAIMER/WARNING/WHATEVER, YOU’LL DO IT ANYWAY…

Make a back up of your dev_flash before attempting anything with writrable flash (PS3 Firmware) slightest mistake could cost you your ps3.

If you do brick, and it blinks when doing so, boot into recovery and re-flash your current firmware – 3.55

Unbrick PS3

The above tutorial covers *soft bricks*, so just be careful, I will not be held responsible for your unfortunate misshaps.

ITEMS NEEDED
[x] COMGENIE AWESOME FILEMANAGER

[x] ASBESTOS INSTALLER 1.4 PKG

1: Download AsbestOS 1.4 & install.

2: Run It. Leave it to install, no HDD light will flash while installing, so you’ll have to just wait untill it finishes.

Once its done it will have PRESS [X] TO QUIT Or something, also you will get an error stating that it could not inject something into LV2 – IGNORE the error.

3. Now go to Comgenie and there you will have another folder saying rwdev_flash.

4. Just be careful, i cannot stress this enough.
