Help System update problem

[twrig106]

Recently there has been a system update for my HTC Incredible (Droid), it had to pause a couple of times during downloading the update (220-250mb in total) and then when it downloaded the system "Update" it asked if i can install it now or later (saying that i cannot make calls, send messages, and that i cannot even use emergency calls) so i allowed it to start installing, it went to a black page with a picture of the phone and a green system update symbol above it, with a loading bar below the pic of the phone. When it finished installing, it restarted, but then when it was turning back on, the same screen appeared, but the symbol of the system update is replaced with a red question mark, and the loading bar was gone, then it restarted again, and ever since then, it always freezes half way through the white page with 'HTC' written in the middle of it, in green. I cannot acess it through my computer or scan it with my computer because it says there is no space on it at all, 0 mb. How can i fix it? do i need to install andriod back on it?
