Hey guys, I made this guide because it doesn't seem to be fully covered and it is very vital.

*DISCALIMER*

Anyone who follows this guide will be responsible for their own actions, NO ONE ELSE...

Recovering your PSP to version 1.50 is when you go into recovery mode and select the option,
"Run program at /PSP/GAME/RECOVERY/EBOOT.PBP" this will automatically bring back your PSP to version 1.50 which is the most stable homebrew friendly firmware, this is useful in the event of a partial brick

----------------------------------------------------------------------------------------------------------------------------------------------
Things to know:

Q: *What is recovery mode?*
A: A special screen that comes with all major custom firmwares, in this you can customize and take care of your PSP

Q: *How do I get to recovery mode?*
A: With your custom firmware press the "R" trigger while you turn on your PSP

*The winstaller may take a long time to load*

*This will not format your memory stick but will erase your PSP settings (ie. UMD auto start)*

*Absolutely virus free, I uploaded this myself*

----------------------------------------------------------------------------------------------------------------------------------------------
How to get 1.50 recovery:

1.) Simply go to this site and download the winstaller: http://www.badongo.com/file/5308985

2.) Run it on your computer with your PSP connected via usb

3.) Follow onscreen instuctions

4.) Congratz

-----------------------------------------------------------------------------------------------------------------------------------------------
Usage:

1.) Hold "R" trigger as you turn on your PSP

2.) Look for the option "Run program at /PSP/GAME/RECOVERY/EBOOT.PBP"

3.) Run it

ALL YOUR BASE ARE BELONG TO US...

I've been waiting for one of these...

yay, customers!

sweet

Yeah, I think this bricked my PSP. I was on 3.71M33-2 and followed the instructions perfectly. When I ran it alot of errors came up and then the "Press X to restart" so when I restarted it, nothing happened...It just doesn't turn on. Have I bricked?

Wow I've told this exact thing to about 20 other ppl and they have gone through it perfectly, it may be a problem with the 3.71 M33-2 FW but anyway...

Keep trying make sure your battery is ok

JIC to you have access to Pandora???

What does my kernal have to be set to? Do I need to enable the PRXs? Because one of the errors was something to do with a PRX.

*PM*

he said he fixed his PSP, and you realy have to do nothing, it installs everything for you...

Weird. Is it my firmware? 3.71M33-2?

I want to downgrade from 3.72 HX-2. I installed the program but when I ran the EBOOT I get an error that says "can not open unmodule.prx. The file can not be opened because it is not on the PSP.
Should I try extracting it from the official $ony update or the HX-2 update or would I even find it there?

I think this might njot work with 3.7_ firmwares.

Great. Thanks for letting me know. I just dumped the 3.72 EBOOT and found out that unmodule.prx is not even there. I guess I will wait until the 3.73 CFW or higher comes out because I am too cheap to set up a Pandora battery.

Does this work with 3.90M33-3?

It should, as long as you have a phat psp.

It doesn't work for 3.90M33-3
