September 17, 2010 // 7:52 pm - Just over a week ago SKFU reported on PS3 Custom Firmware, and today Spanish PS3 developer JaicraB has made it a reality and released a PS3 PS3 USB Custom Firmware Loader!

Download: PS3 USB Custom Firmware Loader v0.2

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.

Requirements:

• Syscall PEEK and POKE.

Installation:

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.

Use:

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.

IMPORTANT!

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!"

PS3 USB Custom Firmware Loader v0.2 Released by JaicraB!

I think that it just decrypts the hard drive (may be wrong) however, certain files on the hard drive are still encrypted.

Glad I am not the only one who noticed it. I already flamed someone yesterday so I decided to take a pass when I saw the original post.

I wonder if we should send our PS3s to him as the next step.

Yep, but it's not tied to the PS3 it's from so once someone figures it out they can just share the file and everyone can use it

Version.txt wouldnt do anything anyways, we need to edit INDEX.DAT which is encrypted

This would be very nice and have a useful perpose. Right now by doing this you are really just loading your own firmware... Which is cool because like it says... you can change what you want and not be online and see what happens. Good for seeing what does what.

It would be better if we could somehow install the new update onto the virtual drive on pc and then transfer the contents to usb and run. Then we can have "updated" systems. But like someone else mentioed. IF we launch a game it resets the sytem and we would return to the original firmware on the hdd and not be able to do anything but be prompted to update again.

Unless someone could get the JB to launch from a backup usb version or external which had the 3.41 on it and the actual hdd had the update. THen we could simulate the hack on the real system. Kinda seems impossible but is a nice idea.

Like if it could when the system is being ran point to the usb with the 3.41 information and then execute that instead of the original.. Wishful thinking..
