How To Downgrade/Load CFW 3.90 to SLIM OR "PHAT" PSP!!3rd

This is the 3rd part of my Tut. thanks for watching! hope it helps! also, to get the CW cheat on your psp its simple.
Plug your USB in to your PSP (after installing the CW CHEAT) and go into usb mode, open up the MS_ROOT 3.71 and grab the seplugings and click and drag to root of mem stick ^.^ done. To get it started, turn you PSP off, completely, then go into recovery mode then down to plugins then activate the very first one. run the game, once in game (after loading and stuff like you moving around.) press and hold select for 3 secs press select cheats, then before you exit out select activate cheats.

Also, when you copy the files, you got to your psp, game, memory stick, which files should you start first, do you have a video showing how to downgrade the actual slim. Also I saw in your first vid, that your lite was bricked but now fixed, when do you need to run MSINST??? Great vids, been looking for a way to downgrade the slim.

Hey I have a Phat and a slim Lite Psp. My slim FW is 3.70, should I upgrade it to 3.80 and start form where you start. Also at the moment Im downloading the file, once you copy the right files, in the end you will have a memory stick capable downgrading your slim and a Pandoro battery that will unbrick your psp right? Also can I use a Phat original Psp Battery for this and use it with the slim if I brick it?

How can I get rid of my 4.05 software in mine? It did'nt come with it I installed it via the system update option on the psp itself.

[NinjaGirlSakura1]

I'm having a problem my psp is the slim version.My software version is 4.05.How on earth can I make this work? All of your instructions worked just fine,but all my psp says is "system software is 4.05 there is no need to update".What should I do?
