Can you really downgrade a 3.80?

Can you use the pandora battery homebrew thing to downgrade to 1.50, or do i need a pandora battery to downgrade a 3.80. I am hearing that you can really downgrade from 3.80 to 1.50. Please help me, thanks.

what?
you can use pandora battery and magic stick to downgrade to 1.50 and then get cfw if thats waht your asking

You can only use pandora to downgrade a PHAT battery since the SLIM isn't compatible to 1.50.
