Stuck in TITAN bootloader? Read this!

[Ksquared9]

Please help. I'm a noob, but I have been trying to solve this problem for a couple of days and have tried everything I understand in this thread. I have a verizon vx6800 that went crazy last week when I was in a remote area and it was constantly roaming. It went nuts and started calling people in my contacts list by itself and then finally got stuck in this bootloader / rainbow screen. It says:

TITA100
SPL-1.04.0000

and at the bottom its says "serial" which changes to "USB" when I connect to my computer. I have been trying to run the titan_extblr.exe program, but keep getting a "Cannot Open USB Port" error. I followed the directions to deactivate the three process in the task manager listed above. I tried the "disconnect activesync" program that someone posted early in this thread. I also went under file>connection setting in the active sync window and disabled all of the options. Nothing seems to work.

I have never flashed a rom, and don't know how. Is that something I need to try? Am I missing something else? Should I start looking for a new phone? I know you guys get tired of noobs asking these questions, but I am really trying here and I would be very greatful for any help.
