I have...
RUU_Bliss_C_VERIZON_WWE_1.26.605.6_Radio_1.15.00.0816_NV_VZW2.67_release_214911_signed.exe
RUU_Bliss_C_VERIZON_WWE_1.26.605.11_Radio_1.15.00.0816_NV_VZW2.67_release_222889_signed.exe
... which I got
here.
--- UPDATE ---
I fixed it. No root, but it's working and back to factory condition.
I used CWM recovery to format all partitions (data, system, cache, devlog, etc.) as well as the sdcard. Once that was done, I relocked the bootloader and ran the RUU. This time I went through the entire setup process for the phone (activation, market account, WiFi and so on) without rebooting first. After the setup, I rebooted and I started normally. About 20 minutes later, I got an android OTA update of some kind and now its fine.
Not sure why setting up the phone would make a difference, but formatting the partitions and going completely clean-slate is probably what did the trick. Something must have been stuck in memory from the first failed attempt and it was corrupting the following attempts in some way.
I'd still like to root it, but anyway... it's fixed and my wife's is glad to get her phone back. Happy ending.
Thanks to all for your assistance.
