Hello,
Well, putting the EBOOT.PBP file in the PSP/GAME/UPDATE folders doesn't work on Official Firmware from what I know... I would recommend you to try updating by selecting the option ''Network Update''. I've never done it, so if you can select which firmware you want to install then do it. If not, then DON'T!! IT WILL TAKE YOU TO OFFICIAL FIRMWARE 6.20! Then, you won't be able to downgrade...
