For any custom ROM and most leaks, there are ways to get back to stock. And s-on/s-off is pretty much just a HTC thing.
The flashing process is different for Motorola phones, but not different in a difficult sort of way. Manufacturers each use different methods, so we have to as well. If you had no problems with doing things on a HTC phone, you'll have no problem learning how to go about things on a Motorola phone.
Thanks for clearing that s-off thing. I was wondering if that was some kind of typo...:biggrin:
