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.

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


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

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 –



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)



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