Installing DAX 3.90 on Slim

[Suzuka09]

My friend asked me to install a CFW on his PSP, but he has a slim, and I have no idea how to do this on a PSP Slim, I've found alot of upgrade guides, but nothing on installing to a sony firmware, can anyone offer me some help?
(Anyway with out Pandoras Battery would be better)

Ok, For slim you need despertar cementerio v3 or v4 and unfortunately you need a fat psp running custom firmware to make it, so if you know someone with a psp on CFW ask them to make it for you. You can get all the files you need here, www.dark-alex.org
