(adsbygoogle = window.adsbygoogle || []).push({}); Yes I know this has been posted but no one has actually bothered to try this while I have and can confirm this works. This is not a copy and paste off another website Ihave done this method myself and can assure you it works. This tutorial will let you downgrade from 3.55 to 3.41 so you can jailbreak your PS3 and play backups/homebrew etc. If you don't have a dongle capable of downgrading, tell me what device you have and I will link you to a PSGrade download for that device.(Or you could just use Google)

Files needed:
Lvl2diag:You must login or register to view this content.

Step 1:Insert dongle(Or PSGrade device e.g iPod) that has been programmed with the downgrade software into your PS3.

Step 2:Turn on the console using the same boot method as all other jailbreaks: Press power then immediately press eject. Your console will turn on wait a moment.

Step 3: Remove dongle and turn on console and you are in Factory/Service Mode. You will see a huge red box on the screen saying Factory/Service Mode.

4. Load any blank FAT32 USB flash drive with 2 files in the root directory:

1. Modified 3.41 PUP
2. Lv2Diag.self (File 1)

5. Insert flash drive into the last USB port to the right — the first USB port in from the right side if you’re facing the console. Turn the PS3 on and you will see a black screen but the PS3 HDD light will flash.

6.The process takes 3-4 minutes for the system to install the old firmware. Towards the end, the power button on the console will start flashing green and then your console will power off.

7.Insert USB flash drive back into your PC and delete the PUP and Lv2Diag.self file (File 1) and copy the other Lv2Diag.self (File 2) to the root of the flash drive.

8.Insert USB flash drive back into the same USB port on the PS3 and power on your PS3. After 10 seconds it will power off.

9.Remove USB flash drive and turn on your console again. You will be out of Factory/Service mode and back in retail mode with 3.41 firmware installed.
