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.

I've just realised my PS3 is being super sensitive when It comes to FW, I've been doing testing with modifying my the update type (CEX/DEX/SEX) flag, manually and with MFW Builder, and my PS3 will only accept the original retail one (with CEX Flag). WTF

Glitchy Joey, made another completely useless firmware which doesn't install any packages at all..

also he promises to make a fully working custom firmware which gives playstation users false hope.. it is easily created in MFW builder just patch shop to retail firmware and no other modifications. any changes to dev_flash will give you a corrupt data error.

i could make another firmware which does install retail packages however it would only install on 3.55 again? i don't see the point..

Sketchy much? If this is modified then I want to know how. I've little faith in NGU but I can seperate my hate for this.

If I remember right there was something about this in the past..? Not sure though, but either way; all of this just seems... Too much.
