PS3 Downgrade from 3.56 to 3.55 Jailbreak
Written by Mark
There is a way to downgrade your PS3 firmware from version 3.56 to 3.55 or lower.
However, there are a few fake sites out there (like
http://www.ps3tuts.com) that are just a scam.
In the
http://www.ps3tuts.com scam, a link to surveys and a paid "premium link" that contains a link to a file containing a comment poking fun at you for falling for the scam.
Simply only use verified sites and don't pay for it.
That said, I did find a work around that I have yet to personally confirm, where you essentially brick (corrupt your PS3 boot software) and then force it to the service screen using a special LV2 file. This allows you to downgrade your firmware. I have had a few reports of this working with the PS3 slim successfully downgrading to the Sony 3.55 firmware but I personally have had issues getting my older version 2 PS3 to actually brick; only currupted hard drive that I get forced to reformat. I am still working on getting some video and pictures to post. Please document your tries and click here to send me the results (or questions) on how it goes. I will post the results. Be sure to backup your PS3 on to external hard drive before trying. Happy bricking.

*** NOT RESPONSIBLE for any problems you may cause to your PS3 ***
Summary: Force your PS3 booting software to be corrupted (brick your PS3) and therefore invoke the console service screen.
You will need these files.
All links are currently working. If a link is down, let me know.
Thanks.

Bricking Methods
#1.)While INSTALLING, (Not download) Unplug the power cord from the PS3. This could take from 1 try to 10000 trys. It's all about what model PS3 you have. The older, the more easier.
#2.)Use an autobricker
#3.)Create a backup, and while it is formatting, unplug your power cord from the PS3. This way is more easier then the FW update method.
#4.)Restore your PS3, while it is restoring, yank that power cord.
#5.)PS3 hard drive corrupt on you? Restore default settings and yank that power cord once again, and say "Hi" to that nice bricked screen of yours.
#6.)Run a piece of corrupted homebrew. (Must be on 3.55 to install corupted homebrew)
#7.)Format your PS3, and while it's formatting, yank that power cord.
Yes, I know you CAN'T get out of service mode on 3.55 and up. But this DOES NOT enter service mode. Your PS3 is bricked, and the Lv2 forces service mode, due to the fact that your PS3 is bricked. This WILL WORK on 3.56. You can downgrade to ANY firmware.
How do you know when your PS3 is bricked?
#1.)You turn your PS3 on, and you have a black screen.
#2.)You turn your PS3 on, and it freezes.
#3.)You turn your PS3 on, and it does nothing.
THIS WILL NOT CAUSE YLOD. YLOD is a hardware malfunction (Yellow Light of Death). Your PS3 overheated and was due for the YLOD. Bricking is ALOT different then YLOD.
To start, this is RISKY. I am not responsible if you fail to utilize simple instructions. Sticking a USB device into the right-most port on your USB port shouldn't be that hard to do.
You should create a backup, it will prevent all your saves from being deleted, your music, photos, and other items etc. to be safe.
To create a backup, insert a USB device into the USB port onto your PS3. Navigate to System Settings-->Backup Utility-->Back Up-->Yes
To restore your backed up files back on your PS3, navigate to System Settings-->Backup Utility-->Restore
I confirm this working, and as you read the posts, so do other people.
To utilize the method of downgrading, you must force a brick on your PS3. Don't worry, this will unbrick your console as well. If you end up with a corrupted hard drive, you will have to set default settings. That is an easy fix.
Step 1.) Download the files needed above.
Step 2.) Format a USB device to fat32. Make sure their is nothing on the USB device, or this will not work. Extract the lv2 file from folder 1, and place it on your USB device along with the Firmware you chose.
Step 3.) Insert your USB device into the Right-Most USB port on your PS3. (Closest to the Disc Reader.) Turn your PS3 on, and your screen will be black. Wait for a little bit, and your PS3 will turn itself off. If it fails to turn off within 25 minutes, turn it off manually.
Step 4.) Turn your PS3 back on, and you'll see the recovery menu. Once you know you see the recovery menu, go ahead and turn your PS3 off. Now, unplug the USB device from the PS3, and insert it into the USB port onto your PC. Erase everything off of your USB. Extract the lv2 file from folder 2 and place it on your root of your USB device.
Step 5.) Insert your USB device back into the Right-Most USB port. Now, turn your PS3 on, it will be unbricked with the firmware you chose.
Good luck.
Basicamente se trata de brickear la consola y despues recuperarla.
