My friend just got a brand new PSP Slim, and she wants me to downgrade it using my Phat, which I told her was fine. I completely forgot how to do it though, so I'm just going over the steps. I've never done it this way, but I think this is how it's done... -Back up everything on my MS. -Format MS. -Put the DDCv5 folder in my GAME folder. -Put the OS Pandora Battery Tool in my GAME folder. -Run OSPBT, which will make my battery into a Pandora. -Since I put the Despertar del Cementerio files in my MMS, its now a JigKick battery, so if I take out the battery and MS after converting to a Pandora battery, then put it into the Slim, it should automatically boot and ask me to go directly to 3.90m33? I'm sure I got something wrong in there, but please go over it with me!
