Dummy’s Guide to Installing Custom firmware on a PSP
Posted by 
January 25, 2008 •
Let’s say that you’re new to the PSP world and all the terms flying around like Custom Firmware (or CFW), HEN, M33, LCFW, Permanent HEN etc is too confusing then please use this guide to educate yourself. Aside from giving you a heads up on the proper terms, this guide will also help you install custom firmware on your PSP.
If you’re unfamiliar with the PSP world, you can start reading up on the CFW for Dummies: Terms and Definitions.
Once you’re done with that (or if you’re familiar enough with your PSP), let’s get started on installing a custom firmware on your PSP.
Let’s start with the basics, what PSP model do you have?
If you need help identifying your PSP model, refer to this guide

I’m relly sorry…but still nothing
Chickhen + Hellcat’s didn’t downgrade your PSP?
# Extract the 3.52 M33 files to your computer.
# Copy the folder ‘M33CREATOR’ to the directory; X:/PSP/GAME150/ on your PSP’s memory stick.
# Download the official 3.52 update and rename to 352.PBP.
# Copy the 352.PBP to the directory; X:/PSP/GAME/M33CREATOR/ on your PSP’s memory stick.
# Download the official 1.50 update and rename to 150.PBP.
# Copy the 150.PBP to the directory; X:/PSP/GAME150/M33CREATOR/ on your PSP’s memory stick.
so we need 1 M33CREATOR in GAME150 folder and 1 more M33CREATOR in GAME folder???
there is no UPDATE in the rar. file of 3.52 M33-4
Please refer to this guide instead. This one is sorely outdate (I really thought I redirected this already)
