Saw the part about extracting the boot.img and using fastboot to "fastboot flash boot boot.img". That step caused the phone to start boot-looping again.
Then I thought I was doing things wrong--i.e. I was rebooting every step of the way (flash ROM, boot to home screen--Then reboot & flash kernel, boot to home screen--Then reboot boatloader and use fastboot flash boot boot.img, then reboot)...So, I tried again, with *NO* reboots...The end result was a phone that boot-looped constantly.
Rats! Here's the info on my phone, in case that makes any difference...

Were you able to get a backup of this rom in this state?
(I know it may not work for your current setup, but I have a phone with exactly the same Baseband (radio) version that I am unable to find an RUU for.
If you have a backup of your phone in this state, I may be able to fix my own phone (by flashing to this radio version).
As I have an HTC One V that is ntelos Branded, tried to flash it to cm10, but forgot (or didn't realize that cm10 is based on Virgin Mobile (different radio I think), and my backup failed.
