i've got a piano black slim psp 2004 with date code 8c. can a custom firmware be put on that? some guys are 'selling' the service of putting a cfw on these models. so is it possible? i already downgraded a fat (1004) with one of the tutorials, but is it the same for the 2004? and, can i put the 'fat' battery into the slim psp and / or put the 'slim' battery in the fat psp? i ask because i have a pandorra battery, it was a spare one of my old fat. can i use that fat battery in the slim versions also? only to down/up-grade to a cfw off course

There are currently no easy exploits in 5.5 firmware so you cannot run pspident, this checks and gives you the board version on the screen.
If you have Medal of Hero's UMD then there is an exploit you can get to run (google will tell you all)
Otherwise the easiest way is to open the PSP and manually check. The type is written on the board.
UNLESS - you have the original box?? the codes from that will tell you what the firmware was at shipping 3.?? and your fine, 4.01 - buggered
it is a second hand psp... no, i do not have the box. and will, off course, not open up an almost new psp. i will try the identifier exploit (in the link you provided in your first reply) to see if it is hackable or not...
