Unable to update ROM, please help

[teamgood]

I thought I was prepared to upgrade, but apparently not because I'm stuck and need some help. Sorry to be annoying, but I messed with it all night and can't fix my problem.

I had a stock never-upgraded Verizon xv6800. I ran the standard Titan unlocker. I then upgraded the radio to 3.35, but after I did this it will restart and then stop at the Verizon splash screen and never loads Windows. So I tried putting it in bootloader to upgrade the ROM to a GPS ROM, but it failed a couple times and then finally was going but got to 10% and stopped.

Now it doesn't get out of bootloader and I can't update the radio or ROM version because even if I could get out of bootloader it doesn't load Windows.

Can someone point me in the right direction to fix my problem or to get my phone back to the starting point?

Help is much appreciated.
