- Memory Stick

This section is how to downgrade your 2.80 or below firmware PSP to 1.50

Instructions:

--NOTE-- If your PSP is anything below firmware 2.80 official, you will need to update to 2.80. Use this file. Place in /PSP/GAME and run -- http://www.psp-hacks.com/file/663

5) Plug your PSP into a computer and run 2.80-1.50DownGrade.exe


6) Choose your PSPs drive by clicking "Browse." Then click extract. The necessary files are installed

7) In your PSP's XMB, go into the PHOTO menu then press on HEN_280. Your PSP will freeze, crash or flash a light blue color then reset. This may take a few tries to work


8) Go into the GAME menu and choose "TA-082 IdStorage Change." Let it do it's magic. Once it is finished it will reboot into the XMB. If you got a message saying "This psp doesn't seem to be a TA-082" thats fine.

Note: If you got an error upon running the program, you will need to try step 7 again.

9) In the XMB go to GAME and choose "PSP Update ver X.YZ." Once it is loaded, press X when asked

In other words: If your PSP is not 1.50, the installer wont work. Try the method under firmwares "All"

Hey I'm a noob with this stuff so I'm prob wrong about this BUT.

I'm trying to install 5.01 m33 from the 3.52 m33 your link in this tut provided, and I'm getting an error saying i need to have at least 5.52 m33-2 installed.

So what I'm thinking is the link you provided is out dated.

Like i said probably not...
