    I have tried everything with this PSP.
    I have one with a 2.71FW and it's also a TA-082 unit, I was able to read both numbers. I'm trying to downgrade it to play emulators.

    I have used two different downgraders
    1. TA-082 downgrader by Dark-Alex (Hend).
    2. 2.71 ta-082 ta-086 downgrader with (1.5 Enabler).

    I always get one of two error messages.
    1. Error Decrypting DATA.PSP
    2. Extracting Prxs. Wrong PDP File.
    Then it restarts.

    Was I suppose to do something, that I didn't. Please help me

    Don't make multiple threads about the same thing. And try using a guide to make sure you don't mess up.

    @TMNTPOWER

    Heres a guide to take a ver. 2.71 PSP with your motherboard to firmware 1.5

    To begin with put aside all the files you already have for the downgrade in a separate folder and format your memory stick. I say this to ensure two things 1)that you don't get the files I give you and the ones you already have mixed up, and 2) formatting the memorystick before a downgrade decreases your chance of bricking.

    Okay to begin you will need the TA-082 2.71 Downgrade Files and the firmware 1.5 update files. Download links below...

    TA-082 2.71 Downgrade Files
    Firmware 1.5 Update


    Now to prepare to downgrade...

    1)1. Open the 2.71 TA-82 downloaded files and extract all files to the root (topmost/first folder) of the memory stick. As shown below...
    [​IMG]

    2)Copy over the 1.5 update EBOOT.PBP renamed to UPDATE.PBP into X:\PSP\GAME\UPDATE\ Were X is the drive letter for your memory stick.

    3)Now either terminate the USB connection or remove the memory card and insert it abck into your PSP. Start your PSP and run HEN D by going to the photo menu and entering the HEN D folder.

    Note: For the next few steps make sure your battery is charged to at least 75% and your charger plugged in.

    4)Go to the GAME menu and and run 1.50 enabler.

    Read: The 1.5 enabler will tell you if you can run 1.5 or not. If it says you cannot press X to alter keys, don't continue till it says your settings will run 1.5

    5)When the program exits back to the XMB run UPDATE X.YZ.

    6)When your PSP has finished downgrading press X to restart your PSP.

    7)When you turn your PSP on there will be a blue screen with a bunch of words and letters and what not. It will say to press O, so Press O.

    8)Congradulations your now at firmware 1.5!


    This excellent guide taken from...

    Also once downgraded to firmware 1.5 I presume you wish to upgrade to a custom firmware like 3.03 OE-C for example. So to help you out I have included links to download installers that make the install process for firmware 3.03 OE-C, 3.40 OE-A, and 1.5 Recovery mode easy as pie.

    3.03 OE-C Easy Installer

    3.40 OE-A Easy Installer

    Firmware 1.5 Recovery Mode Easy Installer (you want this trust me)

    Well most likely the PSP didn't "freeze" it was awaiting a hard reset and for you too reboot it. But since you....

    you bricked it.

    Okay I'll try and clarify a bit. Okay, you know when you plug in your memory stick the window pops up that has the folders MP_ROOT and PSP? You just paste them right into that window. Not the MP_ROOT folder, not the PSP Folder but in the same space those are in. Again not in them but in the same white space that they are. I tried to make a picture to help you out...

    "Now either terminate the USB connection or remove the memory card and insert it abck into your PSP. Start your PSP and run HEN D by going to the photo menu and entering the HEN D folder."

    ^ I went into my psp and ran the HEND file then the screen turned RED and now it's black...what does this mean..what's the next step? Did I brick it?

    Thx.

    Step number 4 is complete, now I'm stuck at "when the program exits to the XBM run UPDATE X.YZ."

    Where do I find the X.YZ and how do I do it.

    Another quick question....I see this msg... will run on this PSP.

    Press 0 to exit

    Do I exit on my own or do I wait? What is the next step and how do I do it?

    The downgrade is completed successfully, thank you very much.

    Like I said above, it was a success but now my question is:

    This was my first downgrade and I've never had an OE version before, so can I automatically upgrade directly from the 3.40 OE-A link which is posted above or do I have to first install an upgrade of 3.30 OE-A?

    Can you please tell me a little bit more about how to upgrade?

    Once again thank you.

    @whynotdee

    Before you go about installing any custom firmware or messing with the PSP lets make this clear for everyone. You are currently at firmware 1.5 correct?

    If so post back as I have links to easy installers for 3.03 OE-C, 3.40 OE-A, and 1.5 Recovery Mode.

    Good morning,

    Yes we ran x.yz, in fact we ran every step with success and the firmware is now 1.50.
