I have a psp 5.51 and now i want to hack it but i haven't got any hack for it please help


With PSP3000 models there is at present No Permanent hack/cfw for it.You can install cfw(custom firmware) on it using chickHen + a cfw. To do this you put chickHen + your cfw on your mem stick and run chickHen first then you can install the cfw which turns the psp operating system into a hacked psp.But if you turn off the psp or the battery is allowed to run flat then the cfw will die,meaning when you re-charge your psp and boot it up, your psp will not run backups again until you re-install chickHen + cfw.Do a search on google or youtube for "howto install chickHen or cfw on PSP3000" .
