psp 2001 fw help

[MindlessMastermind]

okay so i just bought a psp 2001 yesterday that came with v3.95. and my dad decided to upgrade it to 5.03 while i was sleeping
I only bought the damn thing to use homebrew. I know theres an answer for this but I have about 15 tabs open in firefox and i am just overwhelmed. And I have no idea how to find the TA-xxxx number. So if someone could answer me this?
Is there any way I can downgrade or hack or anything so i can use homebrew? Possibly without a Pandora battery and MMS but if thats the only way then so be it.
Thanks!!

nop, only with pandora, even if you were on 3.95 it makes no difference. So there's no need to be angry at your dad

Well i wasn't angry at my dad, he had no idea. But thanks a lot, my mind is now at peace
Everything should come together now. thanks again
