I have 3.52 M33-4 and all it says when upgrading is
Unpacking... done.
Please wait...
and then nothing...
How long should I wait?

@teo42:
Set the GAME folder kernel to "3.52" in the recovery menu.

They're still there n stuff, waiting to be played, but i cant play them! any idea on wha to do??

torrin5 (2008-04-27)

I just upgraded from version 3.71 m33.
All games I tried so far are working perfect but I can't use my memory card for anything else than games. I have music and photos on my memory card that worked perfect before I upgraded but now my PSP says no images/music files on your card.
Is my PSP bricked??? Should I downgrade it and start over???
Pls help me cause I have no idea what to do and I can't find any answers online.
Thanx

Note: if you have problems with the XMB not recognizing photos, music, or videos, its because the fatmsmod patch in this pack is the first version and has a bug. You can get an updated pack which comes with 3.90 M33-3, and other stuff updated (now includes fatmsmod patch v2).
You can find the updated pack here:
