You cannot UN-HACK a psp.
The short answer is no. The PSP slim "CAN" take the larger battery from the PSP-1000 series, but it sticks out and you need to get a custom battery cover for it. The PSP-1000 can take the Slim or PSP-2000 battery, but, the same logic follows. It's best to keep the proper batteries to the right console.
No. If you have psp 3000 it will but any other psp it will work.
custom firm ware is a modification of the psp that lets you use cheats,put ps1 games in the psp ,and much more. you can get custom firmware by makeng a Pandora battery and a magic memmory stick.(for psp 2000,and older)......for psp 3000 you have to get hue or somthing like that .
The thing that powers the PSP. It also enables you put put Custom FirmWare on the PSP
Right now there isn't. If you want to get custom firmware for psp version 6.20 you need to downgrade to custom firmware using a Pandora battery.

you can get alot of games for psp from gamestop or download custom firmwire
There are skins you can buy made custom online for the psp but there isnt an original gold psp
No.
I'm not sure what you mean by "the mod" but I think you may be referring to a "custom firmware". If so, you can safely format your PSP's memory stick without removing the custom firmware. This is because the custom firmware is stored in the internal PSP flash memory, not on your memory stick. If you want to remove the custom firmware, you will need to just install an official firmware onto the psp. The easiest way to do this is to put in a PSP game that comes with a firmware upgrade and choose that option. Then I would recommend having the psp do a Network Update.
for psp
No, you can't.
