Subject: how to install 3.71 m33 on your psp Wed Dec 12, 2007 6:29 am
ee the bottom of the guide on how to 'Repartition the Flash memory' If your PSP freezes while installing files or formatting flash you will need to repair the partition table to enable Pandora to work again.
This guide will show you how to create a 'Pandora battery' that can be used to unbrick a PSP or Install Custom Firmware 3.71 M33-2 onto your Original or Slim PSP. You do not need to modify any files on the memory stick as the multi-ipl loader can autodetect which IPL to use.
To make a Pandora Battery and Memory stick you will need:
Windows Operating system on your PC and a user account with 'Admin' rights A 64mb or higher Memory Stick PRO DUO (256mb or higher is recommended) The total size of all files including the 1.50 Addon is about 40mbytes) Access to a PSP that has custom firmware installed and an original PSP (Thick) battery (A PSP Slim Battery will not work, modifying a Slim battery will make your slim battery not work anymore)
If you don't have a PSP with custom firmware installed, then you will need to either: If you have an 'original PSP', you may be able to downgrade it to 1.50 using one of the downgraders.
Note: If you have a slim PSP you cannot downgrade to firmware 1.50 as the files using are not compatible with the PSP Slim
Find someone who has 'Custom firmware' installed on their PSP and get them to make the battery for you. Only batteries for the Original PSP systems can be converted to a 'pandora battery' Find someone with a pre-made 'Pandora Battery and Memory stick' and use it to install custom firmware on your PSP Buy a Pre-made pandora battery (e.g like the Datel 'Max Power Tool' Battery)
I have modified some files specially so you can use the 'Pandora Battery' as a 'Normal Battery'. The downside is that sleep mode doesn't work at all when using the Pandora battery. You will need to use a Pandora / xmbloader memory stick to turn on the PSP when using the pandora battery.
I've modifed the program so that holding the 'L' button when inserting the Pandora Battery will launch the 'Pandora Recovery Menu, holding the 'R' button will access 'custom firmware recovery mode', If you don't hold any button your PSP will start normally in the XMB.
/!\ Warnings: /!\
By formatting your 'Memory Stick' you will lose all data currently on your memory stick, including game saves, ISOs etc.Please copy everything from the memory stick you want to convert to a folder on your computer before formatting.
Do not use the 'Battery Creator' on a Slim PSP, The Slim PSP doesn't modify the battery EEPROM correctly. If you 'write' to the battery EEPROM, you will end up corrupting the EEPROM and the Battery will not work anymore.
Checking if your Memory Stick is Compatible:
Any memory stick Pro Duo will work as long as its 64mb or higher. The 32mb Duo that some PSP systems come with will not work.
You should be able to buy a 128mb or 256mb memory stick for cheap as not many people want to buy low capacity memory sticks anymore.
Checking if your Battery is Compatible:
The Official batteries (Battery Models 'PSP-110' and 'PSP-280') are known to work properly with the 'Pandora' Files. Your 'Original' PSP System should come with either a PSP-110 or PSP-280 battery.
The Datel 'Max Power TOOL Battery' can also be used as a Pandora battery if you can't / don't want to make your own battery. Do a Google search for "Datel Max Power TOOL Battery" and you will find a few online shops that sell them.

9. The Program will auto-detect the memory stick and will ask 'Are you sure? [Y]', press Y.
10. If you see "Write MS BOOT CODE" then the 'Pandora Bootcode' has been written to the memory stick. You can now close the black MSDOS window since you have the 'bootcode' installed to the memory stick.
(Do not format your memory stick after this, doing so will erase the 'bootcode' and you will need to write the bootcode again)
