I was following this instruction set found here:
http://androidforums.com/evo-4g-all-...-2-rooted.html and I got stuck on 4D.
To make matters worse, I accidentally accepted the OTA install, and my phone has been stuck on this black screen with a white triangle with a yellow exclamation point and an android guy.
My phone appears to be frozen as it hasnt changed from this screen in 10 minutes. I am afraid to do anything with the phone with fear of bricking it.
