Bootloader upgrade w/o Activesync?

[mantispid]

Is there any way to change the bootloader to 2.4 or above without using activesync?

My Alltel 6800 is stuck in bootloader version SPL-2.07.000 and I can't seem to do anything about it. The titan_exitbl.exe file doesn't work other than to reset the device back into the bootloader. I'm pretty sure upgrading to the lastest ROM from Alltel (3.35) may have been the culprit. I didn't realize I needed a version 2.4 bootloader for the GPS roms... but hell, I didn't know any of this and was just upgrading from a stock older Alltel ROM to their latest stock ROM! It shouldn't have crapped out the device, but it did.
