70w ago - Below is a video demonstrating my PS3 4.00 Dev_Flash modification, which simply allows users to install Retail signed package (PKG) files from the PlayStation 3 XMB.
Note: This modification
does not allow the installation / usage of unsigned content / PS3 homebrew etc. This is purely a convenience hack and is aimed for use by those who have hardware flashers which allow dual boot.
After
technodon's work creating a modified kiosk dev_flash which lets you install retail signed package files. The restrictions of having to use kiosk firmware inspired me to find a way to add "Install Package Files" for retail firmware.
This is hack does the following things:
- adds "★ Install Package Files" and "★ /app_home/PS3_GAME/" to "GAME" on the XMB (allowing the user to install retail package files anytime they want)
- adds other debug functions which are small but still there
- does not give access to "★ Debug Setting" (reasons for this are explained below)
Installation instructions:
This installation procedure is the similar to technodon's original dev_flash hdd swap procedure
For this you will need two hard drives a e3 flasher or similar device to downgrade your PS3 (assuming that you're on firmware 4.00 and you have an e3 flasher)
- downgrade to 3.55 using the downgrade tools from e3 (Of course when downgrading to 3.55 make sure you use a different hdd than the hdd which you were using 4.00)
- once booted back into the xmb turn off the console
- swap hard drives turn on the system, press the PS button and you will be asked to reinstall the firmware
- place the pup file from the e3 downgrade tools in the normal PS3/UPDATE usb folder and follow the on-screen instructions to reinstall the firmware
- then install dev_blind.pkg & Blackb0x FTP from install packages
- run dev_blind then BlackB0x and FTP into the console
- goto /dev_blind delete everything and replace them with the customised dev_flash
- press the ps button and the console should reboot and and ask to reinstall the firmware again, switch off the console and swap the hard drive back
- turn on the console press the ps button twice
- the console should boot back into 3.55 Rogero
- goto system update and install 4.00 OFW
- once installed turn the console off again and swap hard drives back and you should boot into a modified 4.00 retail firmware.
My package (downloadable at
http://www.multiupload.com/20LFVKUHDG) includes:
- My modded dev_flash
- OFW 4.00 PS3UPDAT.PUP
Sorry about the camera quality, it's the best I can manage.
P.S. BTW the "nas_plugin.sprx" in this dev_flash has not been altered to achieve "Install Package Files". Also for those who will analyze my modded dev_flash, you will find that I have used debug .sprx files from the a debug 4.00 pup.
P.P.S. I originally intended to get "★ Debug Settings" to work with this. But usage of "debug settings" required the ps3 to use a debug vsh.self, and that crashes the ps3 when trying to load applications (I did some other things as well to prevent the PS3 from giving me a RSOD when I swapped the vsh.self files, I'm not detailing it in public because I don't want Sony to patch it).
hope to find something usefull here .. hello

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 ?

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 http://upsilon-project.webs.com/news.htm'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 "http://upsilon-project.webs.com/download.htm"), 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.
