This guide is intended for use with Official Firmware FAT/SLIM PSP's. If you have a 1.50 FAT PSP or FAT/SLIM custom firmware PSP go HERE and use the guide to walk you through these steps.

This guide will guide you through the creation of a Magic Memory Stick + Pandora Battery that will install or unbrick a PSP to 3.71 M33-2 custom firmware.

In edition I have provided the following UPDATES/ADD ON files.

3.71 M33-4
1.50 ADD ON-2 for 3.71 M33

3.80 M33
3.80 M33-5
1.50 ADD ON for 3.80 M33

3.90 M33-3
1.50 ADD ON for 3.90 M33

3.95 GEN

4.01 M33
4.01 M33-2
1.50 ADD ON for 4.01 M33

===================================================================

Lets get started with the Magic Memory Stick.

Download the files linked below...

Due to the size limitations on Media Fire I have split the download file into 3 parts. You will need to download Part1, Part2 and Part3 then place all Parts in the same directory on the PC and choose Univer_File.part1 to extract. Part2 and Part3 will automatically extract with Part1 creating the complete folder.

Download Link: Part1 Part2 Part3

Mirror:
Send Space Link (1 full file): HERE

Sendspace is a free file hosting service. If you get an error when trying to download keep trying. It just means the free service bandwidth is at max and no more users can download at that time. Just keep trying to download it and it should start the download once a slot comes open).

Extract the file and go to the Easy Installer folder.

Start the Easy installer by clicking on the START Icon.




Select Language 1-3 Then press Enter.




Press any key to continue.

Type in your PSP Drive letter. Then press Enter.




Select "1. Continue To Pandora installer" Then press ENTER




Disable the USB and Format your Memory Stick via System Settings. Then enable the USB again. Then press any key to continue.

Press ENTER when it ask to insert new disc (you should already have the Memory Stick in since you just formated it).

It will scan the Memory Stick.




Type Y then ENTER when it ask if your sure you want to format.




Take out the Memory Stick and then disable the USB.

Then insert the Memory Stick and enable the USB again.

Then Press any key to continue

Select Option 4 "Universal unbricker for FAT or SLIM (This installs custom firmware 3.71 M33-2)"

Type 4 and Press ENTER




The files will now be installed to the Memory Stick.

After it has finished writing the files you will get an image similar to below. Just type Y and ENTER to finish the instillation of files to the Magic memory Stick.




Press any key to close the DOS box.

You are now done with the Easy Installer.

Now go to the ADD_ON folder that was included with the download above.

Drag the PSP folder and 1.50.PBP to the ROOT of the Memory Stick.




When it ask to over Write choose YES TO ALL.




You can now go to /PSP/GAME folder and delete the despertar_cementerio, pan3xx, ospbt, pandora_battery and pandora_battery% folder because they are not needed.

You are now finished with the Magic Memory Stick part of the guide.


===================================================================

This part of the guide will give you some options on getting a Pandora Battery.

The recommended option that I suggest is buying a Datel Tool battery...




You can do a Google search and find a website that offers this type of service battery.

A second option is Hardmoding the battery. This can be dangerous if not done properly. I take no responsibility if something goes wrong with this option.

I also will not reply to any questions regarding this option. I do not recommend it and have not done it myself. You will need to take the necessary steps to find this information out on your own.

I will however provide you with this guide HERE that shows how to Hardmod a FAT/SLIM Battery.

After you have made the magic memory stick and got a Datel Tool Battery/Hardmodded the Battery you can now use them to install custom firmware to a FAT/SLIM PSP.

Just place the Magic Memory Stick in the PSP and then place the Datel Tool/Hardmodded Battery into the PSP and a menu should come up. X will install 3.71 M33-2 to the PSP and O will install 3.71 official firmware to the PSP.

After it has finished installing the files you can then turn off the PSP and replace the Battery with the normal 1. If you Hardmodded the Battery you will need to unmod it to get it back to normal use.

===================================================================

Now it is time to install the UPDATES/ADD ON files.

Go to Game Menu Memory Stick and run MUX 2.0 application.

This will bring up a menu that has all the updates listed.




Choose the update by moving the X at the left up and down with the D-Pad. Then press X when you select the update you want. The Memory Stick Led will flash a few seconds (3.80 M33 and 3.90 M33 flashes a little longer) and after it stops flashing you can go to EXIT at the bottom of the list and it will exit to XMB. Now run the UPDATE via Game Menu Memory Stick.

For those wanting to go to 3.80 M33 or 3.90 M33 or 3.95 GEN just go straight to it and skip the 3.71 M33-4 update.

Those that have a FAT PSP you can also install the 1.50 ADD ON that corresponds with whatever firmware you choose to update to (3.95 has no 1.50 ADD ON at this time).

Trouble Shooting:

If you have issues after creating the MMS and Pandora Battery then read the Possible reasons below.

Vista and 64-BIT XP users may have issues running the easy installer.

Some Memory Sticks are not compatible. Do not ask if your MS is compatible do a search and find out yourself.

New SLIM PSP systems have blocked the use of Pandora Battery Creators.

Not all PSP Batteries can be converted or Hardmoded to a Tool Battery. Do not ask if your battery is compatible do a search and find out yourself.

If your still having issues then keep trying different combinations of PC systems and MS till you find a combination that works.

Great guide larrylje!

Thanks SO Much man That is Awsome, Pure Awsome
Just wondering if there is a Mac one, ya'know like .dmg?

Hi.
Does the file download at the top of the guide include all neccessary files needed to play back up iso games once the custom firmware is installed.If not please could you let me know what I need. Your guide is very thorough, a lot more than others ive seen, but the others mention things like popsloader etc.... do I need these, or does the download you suggest include all files needed. Sorry but am still new to this. Cheers

Hey, you can use this to downgrade a 3.71 Official firmware without a Custom Firmware PSP or 1.50? Also does it work on Vista?

All you can do is try it. Some have used Vista perfectly fine using this guide and others have had issues and ended up needing to use a PC running XP.

Thank you Larry for the fast reply, what size memory stick do you need?

512MB to 1GB is recommended but some have used above 1GB perfectly fine. It just depends on the Memory Stick itself. All you can do is try it.

Did just get my TOOl battery, but after I did charge it and put it "all" togheter to do a NAND dump on my slim, the psp tells me

page 55744 bad block 1742

Is there anything wrong with my PSP or MS etc? Brand new today...

I don´t dare to install M33 right now... please answear
removed

My son's PSP SLIM did this as well.

I did a google search of it and evidently this is normal and has no side effects at all.

I don't know how reliable that information is but it was the answer to all the threads I had read and looked up.

But I installed 3.71 M33 to his PSP SLIM after this had happened and everything went perfectly fine.

Just to put an another question at you directly, where does the NAND going to be a problem actually?

Is it when your have trashed your PSP with custom cintro themes etc, and it fails?

thanks:)

The answer is pretty much never, though, sometimes even the Pandora can't fix a brick and that's where NAND recovery steps in :)

If you just mess around with flash0 then your Pandora would easily fix it like normal.

Did miss a question, but it didnt want to edit the post...

have you put anykind of homebrew on it? like EMU and PSXONPSP (PSP iso can be nice to, but not the main subject)etc.?

on the KNOWN bad block PSP slim?

thanks again

That is the only link available. You need to figure out why your having the issue your having.

Do you think if you could use a normal Battery to install the custom firmware I would give options between a Datel Tool battery or hardmodding it? If you still don't get it then the answer is NO you can not use a normal Battery and Magic memory Stick to install the custom firmware.

It will install 3.71 M33-2 to your PSP (in a way it will downgrade from 3.80 official to 3.71 M33-2).

when I start the psp with datel tool battery and memory stick, nothing shows but the green lamp -no menu, nothing. Any idea what I did wrong?
Maybe it was because I was unable to do that last step in DOS, because it didnt show. Why is that? Has it something to do with the fact I use Vista? Or did I misunderstand entirely, does this tutorial not work for official 3.52?

Answer would be much appreciated


EDIT

I tried with Windows XP, it worked fine then to install. Problem was Windows Vista. Great guide

I have followed the guide above
i have a slim with firmware 3.71
i get to the line that says
Just place the Magic Memory Stick in the PSP and then place the Datel Tool/Hardmodded Battery into the PSP and a menu should come up
i have purchased a Datel tool
I place the Datel and memory stick in and i get a green powered light (yes i did charge up the Datel), no screen, no menu
I have read in other posts re: slim has no screen but you push x or o or such to enable a firmware update and watch the corresponding power/accessing memory stick, lights to show that read/write is occuring. This does not happen either

any ideas?

i have done exactly the same followed all instruction, bought a datel battery got the MC ready but the screen is blank with the green light....
please help

Make sure your placing the memory Stick in first then place the Datel Tool battery in.

If this still doesn't work then try re-creating the Magic Memory Stick on a different Memory Stick.

Vista has issues with some when creating the Magic memory Stick. If your running Vista please try to find a PC running XP and use that to run the easy installer.

sometimes, placing the battery first, then the magic memory stick works better. that way, the psp will activate service mode first, and then load the ipl from the memory stick.

I used to tell others to put the Battery in first then the memory Stick but allot of users had issues doing it that way. They had to add the memory Stick in first then the Battery to have the menu come up.

Either way they should try it both ways.

If it still doesn't work then try re-creating the Magic memory Stick using the same Memory Stick. If that doesn't work then try another memory Stick.

It is also recommended to use XP as the OS when running the easy installer. So if you have Vista and are having issues then Vista could be the problem.
