    THIS IS A LOT OF TEXT - BE WARNED

    Alright so I’m doing it again for you.

    Up until Saturday – I to was a complete noob with a 1.5 PSP, so this guide should take the form of a COMPLETE NOOB guide. So should be simple to follow and easy to understand.
    If you find this guide useful, please consider going to my website - and sign up, or even make a small donation. thanks and good luck
    This guide includes

    You can navigate quickly through this FAQs by pressing CTRL + F then typing in the following header


    Installing eLoader
    Installing the DownGrader (Downdater)
    Downgrading (Downdating)
    Installing Devhook 0.41d
    Installing the firmware Files for devhook
    Compatibility List
    Simple and Easy ISO Compression
    More advanced reading


    So Here Goes…..

    Installing eLoader

    First of all you need GTA (old version unpatched) UMD to be able to use eLoader and to downgrade if you do not have GTA then you needn’t continue.

    Download eLoader here - http://blindraven.net/modules.php?name=Downloads&op=getit&lid=29
    Plug in your PSP to your PC and put it in USB mode
    Unpack the Rar file and run eloader097.exe
    Don’t worry if it says it cannot find PSP - you can select it manually
    Now just follow the onscreen prompts to install eLoader (YES ITS THAT EASY!)

    Installing the DownGrader (Downdater)

    First of all if you have a PSP with the TA-082 motherboard DO NOT attempt to downgrade, there is a VERY strong chance you will BRICK your PSP
    Now…
    download the downgrader here - http://blindraven.net/modules.php?name=Downloads&op=getit&lid=46

    unpack the file – password = I_Use_It_At_My_Own_Risk

    now open the file – you should see 3 folders, 1.5 HELPER, DOWNDATER FINAL AUTO EBOOT and SRC – you should also see a readme – YOU SHOULD READ THIS

    Now copy DOWNDATER FINAL AUTO EBOOT folder to the PSP/GAME folder on your PSP.

    Now you will Need the DOWNDATER folder – you can get this from numerous sources – but please remember that it is illegal
    I CANNOT HELP YOU WITH THIS

    Once you get the DOWNDATER folder it should have two folders (DUMP + PRX) and two files (nputfl.bin + outputfl.bin) in it

    You need to place the DOWNDATER folder on the root of your PSP
    i.e (using x as drive letter)
    x://DOWNDATER

    that’s it for that part – now PLUG YOUR PSP INTO YOUR POWER SUPPLY
    and load up GTA
    select to load a gamesave (if eloader doesn’t auto boot)
    and select eloader.

    Now – if you have never used eloader before you should be still able to figure it out
    Select DOWNDATER FINAL AUTO EBOOT and click X

    Now wait do not touch anything

    Your PSP will go black and your memory stick light will flash like mad – this is normal.
    Once it has finished (usually about 2-3 minutes)
    Your PSP will reboot
    And you will see a blue screen
    Just hit O
    And continue on to set up your PSP’s settings

    if all went well, you now have a 1.5 PSP
    Sorry if you bricked it


    Installing Devhook 0.41d

    Download devhook here - http://blindraven.net/modules.php?name=Downloads&op=getit&lid=27
    Extract it
    Open The MS_ROOT folder
    And copy the two files in there
    Now connect your psp and paste the two files into the root of your memory stick
    Your PC will ask you if you want to overwrite – click yes

    That’s it – now go on your PSP and scrool across to Game and then down to memory stick you should see two things
    A picture saying DeviceHook on it
    And a white picture which is a firmware installer
    For now leave them both and go onto the next guide

    Installing the firmware Files for devhook

    First you need these files –
    PSPBREW - http://dl.qj.net/dl.php?fid=7996
    2.0 FW - http://dl.qj.net/dl.php?fid=280
    2.5 FW - http://dl.qj.net/dl.php?fid=283

    Now unzip and install PSPBREW
    Also unzip the firmware files

    Open up PSPBREW and load up the 2.0 FW EBOOT
    At the bottom of PSPBREW you will see a list at the bottom of this is DATA.PSAR
    Select that and click extract
    Heres a pic, by PSPMeep
    [​IMG]

    Extract the file onto the root directory of your PSP
    i.e
    x://DATA.PSAR

    Now go onto your PSP and back to your Memory stick, and select the white one Devicehook Firmware Installer
    It will detect the date and ask you to extract it, hit extract

    Now do the same for the 2.5 eboot – extract it – overwrite the old 2.0 one – and install with devicehook firmware installer.

    You can now delete the DATA.PSAR file from your memory stick. And your done.


    Compatibility List

    For the full compatibility list go here its HUGE

    Simple and Easy ISO Compression

    WARNING - if your file needs a ppf patch you will need to patch it before you compress - or your patch will not work

    This is just a very simple and easy way to compress your ISO’s, not a particularly great compression, but you can know anything from 15 to 500mb off of the size of the ISO.
    This is simple achieved by unpacking and recompiling the ISO,
    Below I explain…


    For this part of the guide you need:

    WinRar - http://www.rarlab.com/download.htm - these are trial versions, if you do not have winrar then it’s a program you should think about purchasing, its one of only 3 programs I can say that about.

    UMDGEN - http://www.umdgen.com/utilities.html

    And of course an ISO.

    So here goes….

    Download and install WINRAR – if needed

    Download UMDGEN and open it up, just make yourself comfortable with it, look to see what the various buttons do, when you’ve done that just minimise it, we don’t need it yet.

    Now go and find your ISO (check the size)
    my computer is set up so that WINRAR will automatically open ISO files by double clicking them, yours may be different – if it is right click on your ISO and select Extract Files see image below, click to enlarge

    Now if you are used to WINRAR you can skip this part, if not – then you will see this screen –

    [​IMG]

    Extract the file to a folder on the desktop, mine is called AGAME – name it whatever the name of the ISO is.

    Once it’s finished you will find your game on the desktop – open it and you will see a folder named PSP_GAME and a file called UMD_DATA.BIN

    If you do that part is done

    Now open UMDGEN back up – and move those two files onto the right hand side of the screen, using the old drag and drop technique

    Now go to File -> save as -> and save the file as an ISO (name it whatever the original name was)

    And that’s it once it’s done - check the size – see how much you lost, below is the test sizes I did for this guide. (Click to enlarge)

    [​IMG][​IMG][​IMG]

    As you can see I lost all together 540mb, pretty nifty for five minutes work right?

    hey cheers for this raven will try this later on today when i am free! and thanx for replying on my other thread. So is this likely to work for nearly all future games released on the PSP? or will have to constantly update the loader?
    Cheers!

    Oh and the tutorial about "Installing the firmware Files for devhook " is this to trick the psp into thinking it has a newer firmware version or something along them lines?

    yes - you select the option in dev hook

    it reboots your psp

    to whatever firmware you chose

    then when your done just sqitch it off and you have 1.5 again

    2.01 - always stuck there - just in case - my sister had 1.5 for a while

    so i got into it then - but thats when fastloader was king

    then she updated...

    you?

    Bummer, that had to suck up until now. At least for awhile, though, you had 1.5.

    As for me,

    Eh, I got a 2.0 at Christmas and downgraded it. I've never used any other firmware than 2.0 for the first day I had it.

    Edit: Either way, welcome to the world of 1.5. It'll probably add some excitement for you, being as how a couple kickass programs have just recently been released.

    well....still no luck with Daxter (iso)
    It keeps giving an error code.
    I tried replacing the PRX files but after regenerating the UMD it was an iso of something like 3gb....can I shrink it back to 400mb?

    get a hold of ISO compresor - http://www.psp-hacks.com/file/583 to compress to .dax

    as for daxter iso - i dunno - havnt got a big enough mem stick - the iso i have is 1.2gb :S

    Is it true that you can compress psp games without losing any quality/features of the game, at all (whatsoever)!?

    P.S.
    If that is true, then that is amazing!! Unlike the Xbox backups, which you have to take off files in order for it to fit on a 4.7 GB DVD, this gets compressed and works at full capacity? Amazing!

    P.S. #2
    I also wanted to know...is it possible to dump a psp game using fastloader 0.7 to my psp's memory stick and play it right away without the need of turning it to a .iso.dax through my comp?

    Yep, alot of the PSP games are filled with files that have nothing in them so they're useless. Some of these useless files are 500 megabytes, but they include [bold]nothing[/bold]. The programs that compress the ISOs remove that automatically.

    There's usually no loss of quality and there's hardly ever any loss of features, if ever.
