Welcome to the forums

I would try flashing the RUU...... and just so you know it will sometimes sit on that screen for what seems like quite a while when you flash a rom or RUU..... so after flashing let it sit a while without touching it when its on that screen

you can find the RUU here:

Are you seeing what's described in this post: http://androidforums.com/eris-all-things-root/127861-universal-eris-root-dummies-10.html#post1452824 (credit, as always, goes to eu1 for his invaluable help).

If so, it looks like you might have a corrupted ROM (i.e., incompletely downloaded). If this does look like what is going on, try re-downloading the ROM again and verifying its completeness with the dev's published MD5 checksum (should be listed on the dev's ROM page) using something like AFV (Android File Verifier) [which is free in the Market].

Hope this helps.

 

Dude the exact same thing happened to me & I just took it in to the verizon store & got a refurb
