Brick when updating to 2.3? HELP please?

first off, this IS my first post. im not a complete noob, but im not a technical genius. 

ok well heres the story, i recently found out there was an update for my fascinate (verizon), i was pretty excited and decided to download it. so i downloaded it and when it was finished, i hit "ok" to install. i got the black screen with the sort of, un-packing symbol, i guess. thats when i walked away from my phone thinking it would take a while. i came back about 10 minutes later asuuming it was done, and it was at the samsung symbol. i thought this was normal so i waited. i ended up waiting another 10 min, nothing happened, and it was still at the sammy symbol. thats when i turned it off by removing the battery. i tried to turn it on and it again stayed at the samsung symbol. so i removed the batt a second time and tired to boot it up in recovery mode ( vol- + power). a bunch of code scrolled across the screen and it said a bunch of stuff under the normal recovery screen. when i tried to use the volume keys to move through the options, nothing happened. i cant even hit the power button to select "reboot". i also tried plugging the device into my PC so i could use odin. but the phone wont go into download mode. now, heres the weird part; when i plugged it into the wall and tried download mode, it worked. but not when i plugged it into the PC. i tried to plug it into the wall activate download mode again, but it wouldnt work.

im starting to get worried as i really dont want send it in or get a new phone. so please youre help would be so greatly appreciated. if you can figure a way out of this, by any means please help. i dont care if i loose all my data on my phone. im desperate.

i cant use odin or heimdall because my device will not enter download mode when i have it plugged into the computer. 

nope, still wouldnt enter download mode.   

yes, ive been doing quite a bit of searching... i cant seem to find anyone with the same problem

 So your having trouble to huh? Sorry to say but no I did not find a solution. I broke down and called Verizon for a replacement. I just got mine in. Wish I could help, good luck!

.I know what you mean! However, I did not go to a store but I did seriously consider it. I just decided to call customer support to see of they could help at all. I didn't have insurance, but it turns out that I had about 6 months left on the warranty that came with the device. I had no idea it came with a year warranty, but as I now understand, it does! So if you have had it for less than a year, I would recommend calling Verizon's customer service and check.

Hey no problem man! Good luck!
