Its really simple, jst look through all the files and find a "EBOOT.BIN". The file with the Eboot.Bin in it is the file you want to put in your PsP. Where in your PsP? You go to PSP/GAME/
635PRO <---- u can name the file anything you want, it duznt have to be called 635PRO, all you need is a file with any name and then you just drop the Eboot.Bin in that folder. After, jst unplug your Psp from your PC, then scroll over the the game section on the XMB, click on "Memory Stick" and the CFW should be there for you to install.

There is no need to update, 6.37 is a last resort choice cuz, for now, the CFW's still suck, just wait a little longer for a better CFW to come out for 6.37.
Btw, a little +rep for me will be MUCH appreciated
