I've searched many locations for information regarding Rooting and unrooting your DROID. I will provide all of the nessesary steps on how to do both. The Information provided has been done by various people, not by myself. This is just a colection of data for you. I'm not responsible if you brick your phone.
Before we begin, you need to Download and install RSD Lite onto your computer. This program will allow us to install the SPRecovery application to the phone. SPRecovery will be used to install custom ROMs, themes and anything else under the sun. Please watch This Video on how to install it.
