Just bricked my psp

[Kiasko]

Hi i tried to turn on my psp and found out nothing comes on apart from the green light.

I made pandoras battery like 2 years ago and used it to unbrick my psp. Iv forgotten everything i learnt back then.

I want to get back onto custom firmware but i don't know where to start or where to find the files. The newest custom firmware is 4.05m33 right>? Can i go from 1.50 striaght to 4.05m33 or will i have to get to sumthing like 3.03m33 then upgrade to sumthing else step by step? Can some1 also give me the files i'll need or direct me to a guide on pspmod.com of there is one.

Thanks

Look at the links in my sig.

They'll get you to 4.01 M33-2 which is the latest CFW
