i have been searching google and i am getting different answers. Some say there is a blue battery by datel that works on psp 3000?
My only question is, is it possible to unbrick a bricked psp 3000?
Ahhh, reminds me of the days i did full flash0 swapouts to switch from one firmware to another instantaneously when no-one had even heard of the Pandora Battery - living on the edge :)
You really really should know what you're doing before you even touch the flash0... lesson learned i guess (the hard way)...
PSP, all the way from 1.00 to 5.50 GEN D2 - DS Lite w/ M3DS Real (M3 Sakura v1.34)
PS3 3.01 - iPod Touch 2G 16GB Jailbroken - Xbox 360 60GB - PC, Q6600, 3GB DDR2, GTX260 (216) 896MB

That blue battery could probably unbrick a PSP 3000, as it actually put the PSP into service mode (required with phat and non-cursed slims to install CFW). However, Sony saw to it that the blue pandora battery was never released.
The current firmware hack for the cursed slim uses a stack dump method (I believe. Please someone correct me as I'm a noob) sort of like the twilight hack does on Wii. However, it just places unsigned code into ram, and doesn't touch the flash memory of the PSP, therefore is safe.
IMHO, it's a good idea not to mess with themes or any flash related things on PSP that cannot be recovered from a full brick.
