303 HEN

other one (this makes it easier), or insted of replacing your files just put the files or folders (it depends) in the folders they are in in the folder 303 HEN to your PSP.

and logos then it should start up and flash black then blue then restart your psp.

You should now be running on 303 HEN

Do not remove the files yet!

!!BACKUP YOUR PSP BEFORE DOING THIS!!
!!YOUR STUFF WILL BE REPLACED SO BE SURE THAT YOU BACK IT UP
SO YOU CAN PUT IT BACK!!
----------------------------------------------------------------------------------------------------------------

This doesnt make sense buddy, you cant backup anything if you dont have access to flash

And for another matter you didnt link to the mediafire download page you linked it to the mediafire homepage

i tried this yesterday, and everytime i tried to send the UPDATE.PBP to the UPDATE folder it would stop saying that it could not send over and stuff since it doesn't know what the file is.

[laughtub]

so you are saying the file won't go into your psp

You Have To Have Grand Theft Auto and you need to do the steps before that or you might brick your psp
