How do you put a custom firmware on your Sony PSP Slim after you have connected it to your computer?

Go to system setting, system info, n if it said #.## - M33, then it's hacked, if it doesn't say tat, then it's not. So to hack it u basically put the magic memory card in psp (n battery life of Pandora battery need to be more than 78%) then hold the L Button as u put in Pandora battery; keep holding it until a screen appears The screen sud hav an option tat says SOMETHING LIKE: download 5.00m33 CFW, click it, n wait until download finish, don't shut it down or do anything to it, WARNING DON"T TURN OFF When finish, press O or X, then shut psp down, n put the normal battery in. Go to system setting, sys info, n u sud see 5.00m33 Now all u do is go to a psp download website, such as hakopsp.com or pspisoz.com or espalpsp.com n download the game After download finish, extract it (right click on the downloaded item), ONLY EXTRACT ONCE Then take tat file (the heaviest file) n put in the ISO folder of psp (if no iso folder, create one) Now disconnect usb n go to game, memorystick, n click on the game, enjoy Good Luck
