I did not see any errors. I had to manually reboot myself.

WARNING! DO NOT ATTEMPT TO FACTORY RESET FROM ROM! IT WILL BRICK YOUR PHONE! Only from recovery will work without error.
I spent about an hour trying to get out of a soft-brick. It was on an endless bootloop with the dead Android. After button mashing many different ways to get out of the dead Android that was trying to reset, I got to the options and went to AP Fastboot and re-flashed ICS. That was the only way to fix it.
On a side note, there's an error in the fastboot.bat, this line
Windows\fastboot flash rpm_signed JBUpdate/rpm_signed
Windows\fastboot flash rpm JBUpdate/rpm_signed
Since there's no partition rpm_signed, but I guess that doesn't make much difference for people that were able to successfully flash their system since this is just being skipped....
