Quick Question

Do i really need two battery's for my psp?

I have the slim psp dexter pack and i was just going to turn the battery that came with it into a pandora's. I've seen videos and guides of where you can change the pandoras battery right back into the normal one.

So i wanted to make sure if i should have another or if i could just go ahead and make the pandoras and swap it back when i'm done getting custom firmware.

How likely is it to brick?

I always have a spare battery & MMS.

Hm.. don't know how likely is the chance that it would brick? After reading thousands of different tuts and watching vids. I decided i was just going to strip down my battery to make a pandora's. Because i don't like the firmware i have which is 3.90 that it came with.

This is just one of the many but boring vids on how to do it. They all make it look easy enough.
