Need Help With Downgrading PSP Slim

[ShadowLegion]

Today i made a jigkick/Pandora Battery using the psp slim battery, and i want to install CFW but i think i have to downgrade first, im running 3.80 Sony official and i want to use 3.71 M33 or 3.80 M33, but like i said i think i have to downgrade to install it. I tested my battery and it works the Green light comes on without me touching the power switch. And also i need some info on making the Magic Memory Stick. Plz Help If you can.

All the instructions will be same no matter the battery as long as you follow the memory stick part.

There are the memory stick files, I'm not sure if they're for the SLIM however.

And P.S., you do not downgrade, you go straight from 3.80 to 3.71M33 because the slim cannot be downgraded (well pass 3.60 that is).
