1. Download the files provided below for your firmware. 3.50 or 3.55

3.50 Downgrade Files: You must login or register to view this content.
3.55 Downgrade Files: You must login or register to view this content.

PS3JIG 1.00 You must login or register to view this content.

2. Start with your PS3 turned off completely. If your using a FAT ps3, flip the switch in the back. Slim users will need to unplug the power cable.

3. Run PS3Jig on your PSP then connect your PSP to your PS3 via USB Cable.

4. Do the power cycle like you normally would to jailbreak your PS3. (Power then Eject)

5. You may see some screen flickers. You will not have a picture on your screen. The PS3 will shut itself off.

6. Format a USB flash drive. Make sure there is nothing left on the flash drive.

7. Copy over the PS3UPDAT.PUP and the first Lv2diag.self file onto the root of your flash drive. There should be nothing else but these two files on your flash drive.

Alternatively, copy PS3UPDAT.PUP and the first Lv2diag.self onto the root of your PSP Memory Stick.

8. Plug the flash drive into the right-most USB port if your PS3 is laying down, or the top USB port if it is standing up.

Alternatively, Plug the PSP into the right-most USB port if your PS3 is laying down, or the top USB port if it is standing up.

9. Power on the machine. Don't do the normal Jailbreak power cycle. Just power it on. You will get no picture. You will have to wait until it shuts itself off again, which takes about 10 minutes. DO NOT get antsy and think it froze on you and shut it off prematurely. Give it up to an hour before doing anything drastic.

10. Once the PS3 shuts itself off again, plug your flash drive back into your computer again and delete the "PS3UPDAT.PUP" and the "Lv2diag.self" files. Once deleted, copy over the second Lv2diag.self file to the root of your flash drive. Again, this should be the only file on your flash drive.

11. Once the file is on your flash drive, plug it into the same port you had it in before in your PS3 and turn the power on. Again, just a normal power on, no Jailbreak power cycle.

It will stay at a black screeen until it is ready and then shut itself off. Once that is done, remove your flash drive.

Congratulations! You are now done!


INTRODUCTION


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.

AS OF THIS WRITING, THERE IS NO WAY TO EXIT FACTORY/SERVICE MODE ON PS3 FIRMWARE VERSION 3.56, SO DO NOT ATTEMPT TO USE THIS ON PS3 FIRMWARE VERSION 3.56 UNTIL YOU READ OTHERWISE ELSEWHERE!

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?
PSPSDK.

Where's the latest source at?
You must login or register to view this content..

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.

You know, you're really late on this.
I don't care.

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.

How can I scream at you / profess my undying love / throw money at you via PayPal / give a simple thanks / etc.?
