Sorry i'm newbie in upgrading PSP:
I have my PHAT PSP cfw 3.52 m33 so I want to update it to the version I want. but the problem is when I download updater like 3.52 m33-4 and when i click it in my PSP memory stick it will load but nothing happens only black screen will appear and it will turn off. my another problem is when i DL ofw like 3.71 and click it in my PSP memory stick i says " The Game could not be started (DADADADA)" it piss me of.
this is the folder where I save the updater
PSP -> GAME -> UPDATE -> "EBOOT.PBP" i think it is right.
So please somebody help me. i really want to update me PSP.
