February 6, 2011 // 2:18 pm - On this Super Bowl Sunday Brandon Wilson has released PS3Jig v1.0, which is a PS3 Factory / Service Mode Jig Dongle downgrader for the Sony PSP handheld.

He has confirmed the PS3 downgrader / Service Mode Jig PSP port can be used for <= FW3.55 homebrew and works on 1001 5.50 GEN-D CFW. For those interested, IndyColtsFan84 has also made a PS3Jig Downgrade Tutorial for PS3 Firmware 3.50 and 3.55.

Download: PS3Jig v1.00 PS3 Factory / Service Mode Jig Dongle for Sony PSP / SVN

To quote from his page: PS3Jig is a homebrew program for the PSP that emulates the official Sony "jig" stick for entering Factory/Service mode. All you need to do is attach a USB cable between your PS3 and PSP, run the program, and turn on your PS3, just like any other downgrade/service mode method.


Keep in mind that I'm not a PSP developer, and that I know very little about homebrew for it; my ability to answer questions about how to run it and troubleshoot any issues is severely limited.

This application is open source and has no license attached to it, so you're free to do whatever you want with it; but please don't slap your name on it and call it your own, it's just rude.

Frequently Asked Questions

What's the main purpose of this?
To enter Factory/Service Mode on your PS3 using your PSP. This is typically used to downgrade your PS3's firmware version to something that supports homebrew/backups, or you can use it to unbrick some PS3s from a firmware flash gone bad.

Will this cause any permanent damage to my PSP?
Not that I know of, but don't blame me if it does.

Do I need a special cable for this?
No, you just need a standard A<->mini-B USB cable. Among many other uses, it's the cable used to charge/sync PS3 controllers. You have one of these.

What firmware version does my PS3 need to be on for this to work?
As of this writing, you need to be on firmware version 3.55 or earlier. DO NOT USE IT ON FIRMWARE VERSION 3.56 OR HIGHER UNTIL YOU READ OTHERWISE ELSEWHERE.

What firmware version does my PSP need to be on for this to work?
Honestly, I don't know. This requires kernel mode, so as of this writing (and to the best of my knowledge), version 6.35 or lower. It runs on my PSP-1001 5.50 GEN-D.

I get an error when I run it on the PSP! What's wrong?
I really don't know.

How do I get this on my PSP?
The same way you do with any other PSP homebrew. Do some reading and/or googling.

It didn't work! What's wrong?!
Try it multiple times. I have noticed through a hardware USB analyzer that sometimes the PSP doesn't send the jig challenge response correctly, despite the PSP saying it did.

Will this work on the PSP Slim? 2000? 3000?
I honestly don't know.

It locked up my PSP when I tried to exit! Why?
I honestly don't know. Pull the battery, re-insert it, and turn it back on.

What tools did you use to compile/build this?

What dongle ID does this use?
0xAAAA. It can easily be changed and re-compiled in the source. I didn't provide a UI for it because it's unlikely anyone will ever need to change it.

I thought you said this couldn't be done! And yet here it is, prick. What's with the lying?
I said you couldn't implement the PSGroove/PSJailbreak exploit on it, and that's still true. Emulating the Sony official jig stick for Factory/Service Mode is different, and the PSP can do it. I didn't see anyone else doing it, so I did.

OK some nice news related to my works but not the PSP for now. Another experiment -> We can launch the game 3.60+ on 3.55 but the method it's a little bit annoying.

We can play PSP/PS1/PS2 games, etc.. and have many possibilities

I will explain all that and how to do that but i need to focus to put that on a stable way ! and also annoying when you need somebody and it's not here lol...

I was battle with the PS3 system and actually every firmware can support all that... that's why i also make something i can't tell now on the PSP but it would be free and have a software way possibility, don't worry.

I still need to check something but yeah we are soon gonna be free on the PS3 (just small problem i was talking with some friends and cfwprophet about the next update of the PS3 this year that Sony prepare to reduce the kernel, not anymore xmb,
etc... that it's annoying because the PS3 will completely different all the stuff)

And please !! everybody need to boycott the next SSX and Kingdom of Amalur from EA that kill completely the video game !!! please don't accept this.

Crashserious if you read this can you please contact me ? thanks

Helo everyone, i am new here. Nabnab Thanks for your effort, I'll try to describe more specifically my result in:

PS3 ver: CECHG04 OFW 4.00 Folder Ps3Jig in PSP 1004, PS3 back off and restarted immediately pressed the power button eject
PS3 turns on a black background a few minutes then a message appears as unknown usb and normal XMB.

Tomorrow I will try version 4.00 and see if I recognize USB.. I hope to be helpful.

It would be better to report that to Crashserious.

Also as far as i know, the 3.55 don't load anymore the Lv2diag... that's why maybe.

I managed to restore my PS3. I thought I would be stuck in FSM forever when I couldn't remove myself from it with Lv2Diag.self. I intalled kmeaw cfw over it, however, and I managed to suddenly get RSOD when kmeaw got to 99% on the installation screen. Everytime I would turn on my PS3, the FW installation screen would show and I would suddenly get RSOD again. I inserted my usb stick with the RSOD.self, rebooted, and, thank god, I was able to get through the cfw installation and am now on kmeaw.

It still puzzles me that the RSOD.self would work, but the Lv2diag.self used to simply get out of FSM would not...

Agreed. Hopefully it's not too much of a setback. Just to clarify, in my #180 post I'm not comparing CrashSerious' app. I'm comparing team acid's cfw project with nabnab's ps3jig project. I am just still not clear if they are 2 different projects.

The merging of the old thread into this one has caused much of the confusion about service mode. A new thread should be started with a title which makes it clear to users that its for helping and discussing with Nabnab's project.
