Have you tried a hard reset on it. Not just turning phone off then back on, but a full hard reset?
It's probably bricked at this point. Is it even attempting to reload the firmware? You're doing the Power + Vol Down + Enter correct? If that's not working, it's toast. This is going to completely wipe the phone, all contacts, apps, etc will be lost if they're not on the card.
you need to download the rom and reflash it. i do it all the time.
