And only bellow 4.01 (3.95) that is accidentally update to 5.51 can be revert backj to it's old version?

so I'll just wait for the other way to solve this.

Ok thank you.

you got that correct

When I hold the L Trigger and try to install M-33, it says it couldn't find the 500.pbp in the root but I already have it inside the memory stick. What should I do now?

[...BeAkEr...]

download it again, its either a corrupted download or you haven't followed the instructions properly

[Q2468]

The instructions were easy and through the Grader, the installation was complete but when I download another eboot, which folder should I put it in?

[...BeAkEr...]

just drop the eboot on the desktop and load it up via the pspgrader program, it will load the files onto the memory stick itself

Just wanted to post and say thanks BeAkEr. I got my first PSP yesterday, didn't have a clue about downgrading and flashing it until I had read your tutorial. All i did was make my own pandora's battery using a guide i found and then followed yours, only took me 10mins max. Thanks again.

Right now I have 5.50 OFW on my PSP and an 8GB Memory Stick PRO Duo.

I'm having the same problem.
5.50 OFW Psp Phat 1001.
I'm starting to get discouraged so...
Any suggestions?

try another method/tutorial, some pandora batteries simply won't work with this method

hi there, I've just bought a 1003 PSP and was wondering, in the tutorial it mentions that you need to download the sony official 5.00 firmware, so is it a sony official firmware or custom firmware? and also when you want to up date the firmware do you just repeat the process?

I realise this is a pretty simple question, but it took me ages to find 1000 series PSP and i don't wanna brick it
