    Prerequirements:
    Be sure you are on the latest firmware (ATM 4.11 and tested, other version not tested)
    Before you downgrade your device, make a backup of your current BIOS see this topic: http://vondroid.com/viewtopic.php?f=41&t=216

    Requirements:
    - E3 Flasher
    - USB Stick with at least 512MB storage
    - TI 84+ Calculator (can also use other JB device like E3 Card Reader,...)
    Files:
    LV2diag.self file1: http://www.mediafire.com/download.php?ow6xj64nzom2p5w
    LV2diag.self file2: http://www.mediafire.com/download.php?p9h9g9r5peds716
    E3-Downgrade File: http://www.mediafire.com/download.php?a2phdrcefktheya
    TI 84+ JB File: http://www.mediafire.com/download.php?8xkzro42e81mz8e
    True Blue CFW V2: http://www.mediafire.com/?bdo4yeecz23gsb7

    Steps:
    - Format a usb stick to FAT32 and place the "E3-Downgrade File" (unzipped, so you have a .bin file) into your ROOT of the stick
    - Shutdown your PS3
    - set your E3-flasher in the following state:

    - Bootup your PS3 and wait until you see XMB. Press then the start button on your E3-Flasher and wait until the progress bar reaches 100% (this can take some minutes)
    - After it reaches 100% shutdown your PS3 (with power button or in XMB)
    - Start up your PS3 and you will see a message that you need to plug your joystick into the USB.
    JUST IGNORE THE MESSAGE AND PUT THE POWER CORD OUT OF YOUR PS3 (Important step)

    Go to your TI84 calculator and do the following steps
    Copy the 8xk file from "TI 84+ JB File" into your TI 84 using TI Connect
    Run the app on your calculator by pressing the APP
    Go to the option menu and set the following settings:
    Code:
    Stage 1 Payload: None
    Stage 2 Payload: None
    Emulate Jig?: Yes
    
    save the options and press 1. And go back to your PS3

    Plug your TI84 Calculator to your right USB Port see picture below:

    Power up your device and DIRECTLY press your eject button. After few seconds the PS3 will shutdown.

    Unpack and copy the "LV2diag.self file1" and "True Blue CFW V2" to root of your device (File before on your stick can be deleted) and plug them into the same port:

    Bootup your device, you won't see something on your screen but you will see on your stick (if it has an indicator) that he is downgrading your file with the TrueBlue CFW. (at the begin it read the usb, do something on PS3 and then it read the whole firmware file, It will take some time to copy the file +/- 2 minutes)
    After the downgrade, the device will shutdown.
    Log file in my usb stick
    unpack and copy the "LV2diag.self file2" to your root of your device (File before on your stick can be deleted) and plug them into the same port:
    just boot up your device and after few seconds it will shutdown.
    Remove the stick and just boot your device and normally you will boot in True Blue CFW 3.55. On system information you will see on firmware: 3.55
