Well, it's been a long time coming, but root has finally arrived on the Motorola Devour. Although the Devour community may not be as large as the Motorola Droid or Droid X's, they were still as determined as any! The rooting method for the Devour looks eerily similar to the Droid X method, but don't worry, it's no coincidence. For whatever reason, with a few modifications, that same method worked on the Devour. So here you go. Yesterday, the original Devour method was posted by our very own, camperdave here, and had since been improved by bitswitch on Android Central. You will be required to run a script and push a few files via ADB to get this working. If done correctly, this will give you su permissions and SuperUser.apk whitelist. Not so bad, eh? Get it going Devour users, and let us know if it works for you. Remember, DroidForums.net is not responsible for bricked phones!
