Droid X: Restoring and Rooting the Stock ROM.
I'll keep this short: if you're rooting your Droid X, changing ROMs, removing stock applications, etc, then there's a good chance you're eventually going to brick your phone. Having your phone "bricked" usually results in the Motorola logo being displayed indefinitely and or looping with the animated Droid X boot logo. A lot of users will then take it in for service, get it re-flashed, and get a lecture on potentially voiding your warranty by hacking the phone. However, there's tools available that allow you flash the phone back to the pristine state you first received it in.
This guide is designed for the 2.3.32 release of the Motorola firmware, aka the SBF. As such, you will also need to ensure that your bootloader is at 30.03 or higher. Instructions for upgrading both the firmware and bootloader can be found below.
