I saw someone post the link to this in response to someone asking about going back to 748. However, I think this is something that deserves its own thread for those that don't happen upon that link.
Mattlgroff over at droidrzr.com has created an all in one utility for the RAZR. Just go to the www.droidrzr.com and sign up of you are not a member. Go to the development section of the board and our its the top thread.
This tool has fastboot files built in to take you back to 748.... you no longer need to use rsd lite to go all the way back to 744. It also had options to root your device, install root keeper, install boot strap, install Safestrap, among others.
