Custom firmware on Slim PSP

[Erazor786]

Hi all. I'm looking to downgrade a Slim PSP.

I've done a fair bit of reading and understand that i need to create a Pandora bat and magic memory stick. I've got a piece of software called PSP Grader v005 posted by JTH which i understand is needed to create the Memory stick. IVe downloaded the Eboot for 1.5 and the official firmware update for 3.90 as ive read ive needed them.

Just want to make sure I'm going in the right direction in regards to downgrade a SLIM psp. I understand that SLim psp's are not downgraded to 1.5 or something and are done in a different way.

And also wanted to ask how do i create the Pandora battery as I've not found much info on that.

Thanks all.

Thanks for the reply biffo m8.

I understand that Disinter and the PSP Grader are the same things...?

I have got a Phat PSP with custom firmware which i will be using to create the memory stick. I'm just not quite sure what i need to do to create the battery.

When i install the needed files and create the memory stick, are the files needed to create the Battery on the memory stick.

Just need help really sorting out the battery as i think ive got the memory card sorted.

there is a slight difference between the 2 mate.

psp grader formats and copys the files already created for pandora to your memory stick.
it is aimed more at people who already have a pandora battery.

disinter you have to run a few programs to create the memory stick and battery on your PSP.
i would go with disinter mate (on your FAT psp) and follow the guide in this post: Digital Kaos - View Single Post - pandora's battery

the video folder is for mounting UMD films (ISO) mate.

put the UMD ISO (film) in the video folder then mount it using the VSH menu.
