If u want to donate it it would be cool too so that I could continue deving for the d4
I was in a similar situation, ended up going to Cables and picking up a "factory cable adapter" that allowed me to power the d4 even when there was no battery.
I was able to get into fast boot using that then flash the stock ICS rom.
Mind you, I was coming from Eclipse, so I douno how relevant that is, might be worth the ten bucks for the adapter though to give it a try.
edit*
Was able to find my old post on XDA, might be of some use to you, might not, you do this at your own peril.
