If you’re one of the lucky ones who picked up a Motorola Droid Bionic since its launch last week, you’ll be happy to know that the phone has already been rooted, so you can get in on some of the awesome root apps like Wireless Tether, Titanium Backup, and Autostarts.
How to Root the Droid BionicThe process is fairly simple; you should be rooted in no time (Requires Windows):
First, if you don’t have these already,  you’ll want to download and install the Motorola USB Drivers for the Bionic. Restart your computer once the drivers have been installed.
Next, download Motorola One Click Root. Unzip the file and navigate to the location of your download.
Then, set your phone to USB debugging mode. Press the Menu button on your Bionic, then select Settings, then Applications and then Development. Tap the checkbox to enable USB Debugging.
Next, we’ll want to plug your phone into your computer and select “Charge Only” mode when it asks what you want to do with the USB connection. On your PC, navigate to the folder you downloaded before (should be called “MotorolaOneClickRoot”) and run MotorolaOneClickRoot.exe. Follow the instructions that appear in the command window.
Your phone should complete three steps, rebooting several times along the way. The command window on your PC should let you know when it’s OK to use your phone again, and you should be rooted! There’s a ton of things you can do once your phone has been rooted, check Google and places like XDA-Developers to look for some tips for good root-only apps.
Keep in mind that this root is not permanent, and may be affected by OTA updates in the near future. If you need to have root, you may want to deny any OTA updates that your phone tries to give you over the next couple of weeks, until a more permanent solution is found.
