Need Help PSP Freezes And Shuts off On Start Up

[TheUnknownMerc]

yo guys i was recently trying to edit the gameboot...so i basically copy and pasted over the original in usb mode....and i put it in F0 -> VSH -> Resources

so i started it up and it froze before it even got to start up (before intro to psp no the actual game)....so i tried putting the original back in but it doesnt work....ive also tried to use the bypas sony logo function (since i can access recovery mode) but still nothing

dono whats wrong anyone help? btw my specs are:

4gb memory card
5.01 (i think might be 5.00) m33-4
PSP-1000

any help is greatly appreciated thanks ^_^

i also have pandora battery and magic memory stick if needed =P
