you can't... you will need Pandora..
find a hack PSP with 1.50 or CFW. then make the Pandora battery. then you will be able to downgrade your PSP..

sorry that's the only way..

hi captain how are you..any new psp firmware like 3.71m33-4 or 3.80 etc:thumbup::thumbup:..:thumbup:;)

any downgrader for 3.71m33-2 to 1.5....:rolleyes:

Read the first post this will downgrade any 3.71 M33 1-4. 3.80 no, maybe when the M33 one comes out, we'll see.

I'm having a problem, I run the program but it says it can't find UPDATE.PBP?

ok when i look in the file while in the ZIP folder i see the update.pbp but i can't seem to move it, as if it doesn't exist. When i try to extract them it says the file UPDATE.PBP is corrupt.

Try re-downloading it, or download it from a a different computer, there's just a corrupt file your getting. That link on the first page was just updated last week so it should be fine.

I was halfway into making a pandora battery when I found this here thread, a nice little package you've there, mang. Saved me a lotta trouble.

Oh yeah, the update.pbp was reported as corrupted by winrar, so you might wanna look into it. peace

;):D:rolleyes::rofl: HI CAPTAIN WISH YOU AND ALL A VERY VERY HAPPY NEW YEAR...THANK,S FOR YOUR SUPPORT...:thumbup::thumbup::thumbup:
