Is this a solution to downgrade 3.03 psp?

Question

My psp runs on 082 motherboard, used to run on 2.71 firmware, but my 'friend' just had to upgrade it for me into a 3.03!
Yes I know there are no downgrades avaliable now for 3.03 (thats why i want to punch him hard) but i was wondering if changing the motherboard to another 082 with 2.71 firmware or lower would work? Oh yeah side note, my psp runs on region 3 (asia) from hong kong, and im in Beijing so i guess getting a motherboard here to replace is fine right?

Thanks if u helped =]

That is a pretty hardcore task. Your best bet is to either wait for the 3.03 downgrader to come out, like the one for 3.02 here ( http://www.qj.net/Custom-Firmware-3-02-OE-A-released-by-Dark-AleX-/pg/49/aid/76935 ) or go here for more help ( http://www.psp-hacks.com/forums )
