DO NOT try this with a slim
Alright first off you need these two files, one is the .pbp from Sony and the other is the kernel installer.
150.pbphttp://www.mediafire.com/?51jiydnjmdu
Kernel Installerhttp://www.mediafire.com/?nzntglbzjzj
To open these you need winrar, if you do not know what that is then google it.
Ok after downloading 150.pbp you should place it in the root of your memory stick, it should look like this:
Ok after that unrar the other and place it in the (drive letter)>PSP>GAME5XX folder it should look like this.
And inside the 5XX folder.
Ok after that disconnect from your usb go over to your memory stick and run it.
After that you can delete the two files off your psp.
Happy Homebrewing
