ok well i just bought mine but it was used and i looked at the official firmware and it was 4.20, so i used the official update 5.03 and then updated it to that official firmware and then i used chickhen for my firmware 5.03 and then i used Gen A to play psp and playstation games! if you look in system settings then look at system info youl will see ur firmware, if it is below 5.03 then use this method with these files
ok download this file i made for you, then extract all 4 files.
extract psp 5.01 fw update and put the eboot file in a folder named UPDATE and place that folder in your psp. hook your psp up to your computer and go to psp then game and put the update folder in game.
now make sure you have a full battery or at least a half charged batt with the charger on it! repeat keep your chrager on at all times from now on. now go to ur psp and chose the game option and the update folder will be there and hit x and it will go to the update process and just hit yes and agree to the terms and it will update the psp to ofw 5.03 and it will ask to shutdown. now turn on the psp and check system info to see if it is 5.03. it should be
no hook the psp back up to the computer and go to the picture folder and delete and pictures you have. now extract the chickhen file and put the slim picture folder with the files in the picture folder. put the chckhen for psp slim in the picture folder on your psp[ make sure that the pictures are in the chickhen fold} just open the slim folder and put the chickhen folder in ur psp picture folder k
and make sure you also put the h.bin in the root of the psp. this means the first folder you see when you open the psp. if you dont know what root of a card is then find out, its the very first folder thing that comes up when you open ur psp memory stick on ur computer
ok see the folder psp and others thats your root. put the h.bin file there,
ok and now you can put the 5-03gen-for-hen files in your psp. hook uo your psp to the computer and go to PSP then GAME look to see what the name if your psp drive is and run the the file called lauch me in the gen file for hen and it will bring up a menu. select what psp you have 3001 for you and then chose full install and psp install chose yes and then put the drive letter or name in the psp unit drive box. for instance if your psp drive name is G then just put G. you can see what the drive name or letter is by looking at the root folder and look up at the right top corner and it will say the name. then hit start and it will finish pretty quicly.
ok now go to ur pictures folder and open the chickhen and dont press anything and it should load if not then try again and when it does go green and load go to ur game folder and run the installer loader file and the hit L or R to install custom firmware then whens its done hit O and it will load in the fully hacked mode which lets you play psp games and psx games as well.
you never have to install the custom firmware and but you have to uyse the loader every time you turn it completely off.
see when you turn it off completely then hack is gone but all you have to do is run Chickhen again from the picture folder the run the installer loader and hit just O and it will load fully hacked again. you must repeat this step when ypu turn it off
