Stuck in Bootloader after ROM update

[wvufan]

I'm at a complete loss. I tried the alwaysbelieve1_3.5 rom update from this site on a VZW 6700, and it appeared to complete correctly, but after saying complete, I cannot get it to exit the bootloader. I've tried soft-reset, power/voice/reset combo, hard reset (which prompts for clearing, but after reboot, goes back to the bootloader). I've tried reinstalling the stock (APAC_VZW_20720_200_11000_Ship), but it complains about a connection error. I've tried reinstalling the alwaysbelieve1 update, and I've tried running the sar_aku3.5+_pr5 update manually. Nothing works.

How can I "unbrick" my phone?

Thanks for any assistance out there!
