how to downgrade psp ver. 3.95 to 1.5??

can someone tell me how to downgrade my psp firm ware to 1.5

get a Pandora's battery and a memory stick between 64 MB and 1 GB for the "magic memory stick."I know the 4 GBs aren't supported.I have a tutorial that isn't moved to the tutorial section yet, but my tutorial will guide you through the procedure.The process is so much simpler than having to downgrade to 1.5 and carefully working your way up.
It pretty much wipes out the existing firmware and puts in the one that you want.If you're too lazy to use the search function, here it is:

last time I tried to buy a pandora battery from the net,i got ripped off, it was actually just a normal battery, that didnt work at all...waste of 80 bucks..

OMG. $80!Buy one here for $10.13: http://www.dealextreme.com/details.dx/sku.12472~r.24128850They raised it 13 cents but who cares.I might add that for the newer firmwares, the pandora's battery is the only way to downgrade.
