Help! stuck in bootloader, usb won't work

[ig88b1]

after reading about roms and radios and bootloaders for a week, i decided to try it. i ran olipro 2.40 and the first and second steps went fine. on the third, when it stops and asks you to make sure there is a connection, i diddnt have one. i looked at my xv6800 and it said (on the screen) to 'push power to upgrade. i think this is because i had a radio rom in the sd slot. i pushed power, and it hung. i did a soft reset, and now i have a triple color screen that says TITA100, SPL-1.04.0000. at the bottom, it says usb. but the pc wont recognize a connection, other than installing drivers. what do i do?
