									?
Lots of users downgrade their PSP to version 1.5 because they can upgrade their PSP
to any version from 1.5. And if you upgrade your PSP to version 3.51, you can play
any downloaded games and run any applications. Do you know that you can
downgrade your PSP system to version 1.5 all by yourself by turning your PSP battery
into a pandora's battery? All you need are an original PSP battery (with more than
50% charge) and a Memory Stick Pro Duo with 1GB memory or above.

I. Get ready (Reformat PSP memory stick)

Before you get started with the downgrade, you need to reformat your PSP memory
stick. If you don't know how to reformat it, you can refer to the steps below:


1.Press the HOME button on the bottom left of your PSP.
2.Use the arrow keys to move to the Settings area, then move the up and down keys to
go to System Settings.
3.Push the "X" button (or the "O" button, depending on which button is the "Enter"
button of your PSP) and scroll to find the "Format Memory Stick" option. Push the
"X" button again to select this option.
4.Your PSP will now confirm that you want to reformat the memory stick, choose Yes
and your PSP will be physically formatted in a few seconds


To do the downgrade, you also need to download an application pack. Click
Download Pandora Battery Application Pack (Find the Guides label on the right
side,which named Download for PSP downgrade application). After the downloading
is finished, what you get will be a compressed application pack named "pandora",
decompress it to the root directory of a hard disc, say Disc H. In this "pandora" folder,
you can see four folders including mspformat, msinst, battery and installer, and a file
named UPDATE.PBP.


Now you are ALL ready to turn your PSP battery to a Pandora's battery and use it to
downgrade any PSP!

II.Turn your PSP battery into a padora's battery

Step 1: Logically reformat your PSP
Connect your PSP to your computer. And your PSP will be recognized as a new hard
disc, say K. Then click Start -> Run, input cmd in the popped up dialog box, and click
OK to enter DOS system. Use the below commands one by one to run the mspformat
file:
Input "H:", and press the "Enter" Key on your keyboard. (Here H is the disc where the
"panndora" folder is located)

Input "cd pandora" and press the "Enter" Key on your keyboard.
Input "cd mspformat" and press the "Enter" Key on your keyboard.

Then input "mspformat.exe K" and press the "Enter" Key on your keyboard. (Here K
is the name of the disc that your PSP is recognized on your computer.)
After these commands, your PSP will be logically reformatted in a minute.




Step 2: Open the recognized PSP hard disc on your computer, create a new folder and
name it "psp", open this "psp" folder, create a new folder and name it "game". Copy
and paste the "installer" folder and the "battery" folder into the "game" folder. Then
copy and paste the UPDATE.PBP file to the root directory of the PSP hard disc on
your computer.

Step 3: On your PSP, switch to the Game option, press X or O (depending on which is
the "Enter" key of your PSP). Go to "installer" and press X or O to run it.




In a few seconds, a file named "msipl.bin" will be created on the root directory of
your PSP memory disc. And now, you should take out your memory disc and then put
it back in, which seems to be useless but is a very necessary step.

Step 4: Connect to your PSP back to your computer. Then enter DOS system as
mentioned in Step 1. Use the below commands one by one to run the mspformat file:
Input "H:", and press the "Enter" Key on your keyboard.
Input "cd pandora" and press the "Enter" Key on your keyboard.
Input "cd minst" and press the "Enter" Key on your keyboard.
Then input "msinst.exe K K:msipl.bin " and press the "Enter" Key on your keyboard.
(Here K is the name of the disc that your PSP is recognized on your computer.)
When you see a popped up message asking if you are sure, click "Yes".

Step 5: Go back to your PSP, switch to the Game option, press X or O (depending on
which is the "Enter" key of your PSP). Go to "battery" and press X or O to run it,
press X or O to OK every popped up message to finish running the battery
application.


Now, your pandora's battery has been created!
III. Use the created pandora's battery to downgrade your PSP


After you turn your batter to a PSP downgrade battery (pandora's battery), you can use
it to downgrade your PSP by following the instructions below:

Take out your PSP Memory Stick and battery, then put back in your PSP Memory
Stick first, and put your battery back in.
Turn your PSP power on, when you see three options; select the Downgrade option,
your PSP will be downgraded in a very short time and it will be automatically shut
down afterwards.
Turn your PSP on again, and you will see a blue screen. But no worries, you can just
press the O key, and your PSP system is already version 1.5!
Note: The above process will turn your PSP battery to a pandora's battery that can be
used for PSP downgrade. But the pandora's battery cannot be used to play PSP games,
videos or music. And the process is not reversible. You will need to get an additional
PSP battery for regular uses. However, you can use your pandora's battery to
downgrade any PSP to version 1.5 or even repair you PSP.

Now, you can get a new battery and use your downgraded PSP to upgrade to 3.51 or
high version for play downloaded games, view pictures, read digital books, and run
various free applications unblocked!This is another part about refresh PSP system and
I'll expatiate later.I travel very frequently for my work, and another big use of my PSP
is to watch movies on big and wide screen of my PSP. I have lots of DVD movies, so
I always put a few movies on my PSP if I am going to travel. I have tried a few tools
and the one I am using is named iSkysoft DVD Ripper. The conversion quality is
really good, and besides PSP, I can also use this application to put movies on iPod,
iPhone, Apple TV and almost any players. I have been using it for a few months, and
so far, so good! If you are running a Mac OS, I have noticed they also have a version
for Mac users. But I have never tried it before since I am only running Windows XP
on my computer.
