Hello, and please HELP!!!!

[shakezzzullaa]

Hello everyone,

Before I get started with my plea for help... Happy New Year. I am a relatively new Android User/Epic Owner. Today I tried doing the DK28 update. I read in several places that if the phone "gets stuck" just pull the battery and restart. Of course, my phone got stuck and so I pulled the battery and attempted to restart the process. However, now when I try to turn on my phone it just goes right into a black screen showing an image...
The images shows a cell phone on the left side, 2 dots, an exclamation mark inside an orange triangle, another 2 dots, and then an image of a PC on the right side. Does anyone have any ideas as to what this could possibly mean?

Thank you in advance.
