Well, all I can say to try and defend myself against any mistakes, this is my first attempt into rooting and flashing custom ROM's, so bear with me please >.<
Followed the instructions exactly as stated. Went to reboot, got to the Motorola M and it stayed there. Left for an hour to let it do it's thing and come back to find it right as I left it. Managed to get my phone rebooted into ClockworkMod Recovery and restored to my pre-flash stock ROM.
My Procedure:
1. Rooted my phone using SuperOneClick v.2.3.2
2. Downloaded HeXen, moved .zip file to SD card
3. Used the mentioned Bootstrap to backup, wipe, and install HeXen from .zip
4. Rebooted from ClockworkMod
5. Encountered problem
6. Yanked battery after waiting an hour
7. booted into ClockworkMod
8. Recovered pre-flash ROM *whew*
Help greatly appreciated!
EDIT: Gonna nuke my phone and start over and see if that works.
