    I believe you have the files wrong on your "Jailbreak Device" and you need to start from square one again and proceed forward.

    hi... have you following those step? i think it can't downgrade 3.55 firmware... make sure your usb in fat32.
    How to downgrade firmware 3.42/3.50 or above to firmware 3.41 with PS3break dongle:

    1. Insert PS3break dongle device into computer and flash in downgrade mode firmware as downgrader.
    2. Insert PS3break dongle device that has been reprogrammed as downgrader into your console.
    3. Turn on the console using the same boot method as all other jailbreaks: Press power then immediately press eject. Your console will turn on and PS3break dongle will light up green LED.
    4. After few minutes,the ps3 console power off automatic and red LED light up.
    5. Remove PS3break dongle and turn on console to make sure you are in Factory Service Mode. You will see a huge red box on the screen saying Factory Service Mode.
    6. Load any blank FAT32 USB flash drive device with 2 files in the root directory:
    -1. Modified 3.41 PUP
    -2. Lv2Diag.self (File 1)
    7. These must be the only files on the USB key and must be placed in the main (root) directory.
    8. 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 black screen but the PS3 HDD light will flash.
    9. 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.
    10. Remove the flash drive and turn on the console, you will still be in Factory Service Mode. Please verify you have downgraded successfully to version 3.41 by going to “System Information”.
    11. (Optional) – If you wish to downgrade to any older firmware you can follow step 4, 5, 6 using any regular firmware PUP. (You do not need to use modified custom firmware now that you are on 3.41).
    12. 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.
    13. 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.
    14. Remove USB flash drive and turn on your console again. You will be out of factory service mode and back in retail mode with your chosen firmware version installed. You will need to go through setting up settings configuration.
    To go back to PS3break dongle device, just drag back the normal .hex files.

    Regarding Blu-Ray support after downgrade:

    Blu-ray works normally as we have tested.
    i almost forgot... it wouldn't works on ps3 slim CECH-251x series.. only CECH-25xx.

    Since the PS3 unit is on 3.42 firmware, it should work. You just need to follow the instructions as posted previously.

    Upgrade to 3.50 and try it again. Watch the model number if it's CECH-251X you can't downgrade. And take a look at the barcode - is it bold or not ?
