EASY Downgrader for 3.71 M33 to 1.5 Without Pandora; Through Recovery Menu

[Choby]

Okay, thanks pal.

Damn! I just read on his first post it says:

-Must Be Already On a Semi-Bricked 3.71 M33 PSP

Gonna have to find another solution.

You don't HAVE to be semi bricked. I already said that lol. Look here:

Yeah this is MEANT for semi-bricked PSP's because the recovery menu is what it's run through and that's all you can access with a semi-brick. But yeah you can use this on a regular 3.71 M33 PSP too. To all the idiots out there looking to see if this runs on they're PSP, first check the FIRST PAGE for information but MAKE SURE YOUR ON 3.71 M33 CUSTOM FIRMWARE. This is NOT for JUST 3.71 SO STOP ASKING PEOPLE, why can't some of you just read?

Captainmorgan please update the first post saying this.

I installed it on my psp, and ran the installation, but it still says i have firmware 3.71 Have I done something wrong?

p.s it goes on the psp startup screen then a message pops up saying "This game could not be started. (80020148)

Can I just check that I'm doing this right?

It never seems to have any effect.

I hold R and turn my PSP on to enter the recovery menu. I toggle the USB on, and copy the two folders into PSP/GAME. Then I use "Run program at /PSP/GAME/RECOVERY/EBOOT.PHP.

Then the screen goes dark, and the top light on the left flashes orange a couple of times. Then the PSP boots as normal, and I go to check the firmware, only to find that it's still 3.71 m33-2.

Any ideas about what's wrong?

Make sure you have the file(s) placed in the correct folders and that the folders are labled correctly and placed in the right directory on your memory stick pro duo.

This is for 3.71 M33. Read the title.

Just a quick question. If this proess was to somehow brick your PSP, could one be able to restore one's own backup of his or her NAND to the motherboard of the PSP to return the system back to it's previous state? Exactly how difficult is it to restore a NAND on your own PSP using either Pandora Battery with a logical restore or Dark_AleX's Desperatar del Cementerio V3 with a physical restore? What is the difference between the two types of restores? (Logical & Physical) I know how to go about backing up the NAND for my unit, that much is simple, but how would I restore a NAND dump from NAND-DUMP.bin on the memorystick using either process? Is it even safe? I would greatly apperciate anyones feedback on this mattter. Thanks.

i have 3.71 m33-3 is it stil posible

[Vampiric Inuyasha]

I would assume so Rad. Before coming across this thread I posted a thread about a problem I have which people thought wasn't about the firmware. Anyway I thought upgrading to -3 would fix my problem but it didn't, hopefully this will solve my problems. I just wish people would read the first post, and read that if your firmware doesn't have M33 at the end then this won't work for you.
