Recently you can not make your psp with a custom firmware with out Pandora, Think about buying a Pandora battery on eBay, they are cheap.
you cant, you need 3.03 or below to downgrade without Pandora stuff.
right now you can only do a half byte loader (homebrew)
There's a chance it will break it, it allows you to downgrade your firmware so you can put on custom firmware, this is ILLEGAL. Also, if you do it wrong it would destroy your psp
Get a Pandora battery and use UMD extraction software then convert it from an ISO to a CSO and put it on your memory stick.
You can only get cfw without a Pandora if your psp is firmware 5.03 or lower and you use the program chickHen to do so.
No.
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 .
No, you can't.
most of the time
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.
If you have official firmware you can only play demos If you have Custom firmware you can play all kinds of games So You Don't have custom firmware
No only if you put cfw (custom firmware) on it by hacking.
