To quote from his site (linked above), roughly translated:

"This program allows to simulate the dev_flash from USB. Allowing a Custom Firmware. We may modify the files of our new dev_flash (USB) as we please, without running the risk of throwing away the PS3.

It is a beta version, probably find bugs. I will continue working on it when time permits me. Remember that suffers no risk to the console. All that is changed the new dev_flash'll be doing really USB.


• Syscall PEEK and POKE.


1. Copy the "FTP server" the entire contents of the / dev_flash the USB (the root).
2. Copy the JaiC_USB_FIRM_LOADER.pkg also the root of the USB.
3. Install the package.


1. Insert the USB into the PS3.
2. Run USB LOADER FIRM. After a few seconds will return to the XMB. The new firmare is loaded.

You will see that whatever you do the USB will be launched. Ideal for amending RCO, exchange modules, as you imagine.


Do not update while in Live Firmware Mode. It will reboot, setting the original dev_flash back, and then it will update! Do not update from USB FIRMWARE LOADER!"

maybe someone could make a debug/retail hybrid containing the best features of both, if the contents of a dev_flash (debug) were available to the public

I have a theory on your theory there. If this unit updates for any reason, welp, I was thinking while jailbroken, run the 3.42 update, until it extracts the data on the ps3 itself. a PUP Unpacker probably won't extract those "unextractable" files.

That being said, External fw loaded or not, I'm sure after it extracts to the HDD temp folder, shut the unit off and turn it back on in JB mode, load up FTP, and see if the files are in the temporary folder.

I'll try that out now actually.

I remember someone mentioned either in this thread or on irc about trying to load the 3.42 update but we cant get the dev_flash files extracted as its encrpyted.

What if we were to load the 3.42 update from the usb loader cfw loader, would this then extract the contents of 3.42 onto the usb stick, then click no to updating or even just remove the stick and examine it for changes?

I am so hoping the jailbreak can load up on my other ps3. I bought a 60GB on craigslist, card readers, 4 usb ports, the works.
It was locking up and firmware froze up here and there because of the hdd.

I hope soon we're able to load up external firmwares via USB, cus this thing is just SITTING on my stand lol :]

Devs, let me know what I'm going to be testing. I'm about ready to use this current ps3 as a test box

Have any one here with two ps3's, tried to load the dev_flash from one ps3, on to the other one?

Just to check if it is even possible to load someone elses dev_flash?
