The only way to get it to work (as I believe I have already told you through PhatNoise.org) is to buy, beg, borrow or steal another original DMS to apply the hack from someone near you.
Some people might even let you send them your PhatBox so that they can hack it for you - but you'll need to:
a) Ask
b) Mention which version of the PhatBox you have, and with which head unit you plan to use
