Step 3: Preparing the Droid for Root
Once you have unmounted the phone, it is now time to prepare the Droid to receive the Root files. You will be accessing Recovery Mode to do this, a special Android console which can be used to manually recover and install updates. Start by powering down the phone completely.
While holding “X” on the physical keyboard, hold the power button to turn on the phone. You may let go of the power button, but do not let go of X.
After a few seconds, an Exclamation Mark icon will appear. You may now let go
Full System Backup Using Nandroid

As you learned in the
Custom Recovery Image guide, SPRecovery is a powerful recovery replacement that allows you to make full system backups. What do we mean by “full system backup?” It is a package created by Nandroid, a utility within SPRecovery, that contains all of the data and system information on your phone. In essence, it’s a direct 1-to-1 copy of your Droid’s software. We can take this copy and save it in case something goes wrong. If we don’t like the way our Droid operates after a certain hack or if we brick it completely, we can take this backup and restore our phone to a working state.
It’s a very simple process and does not require a computer at all. I recommend making a Nandroid backup at least once a month and before every major hack you perform on the Droid. You can never be too safe, and it would be a nuisance to backup to an earlier state that does not have your most recent data. Remember, save often; avoid frustration.

Requirements:
Step 1: Boot into SPRecovery
Power down the Droid completely.
While holding “X” on the physical keyboard, hold the power button to turn on the phone. You may let go of the power button, but do not let go of X.
After a few seconds, a green-gold colored Android logo should appear behind the SPRecovery Console menu.
You may now let go of X and are now ready to perform a Nandroid backup.
Step 2: Perform Backup
From the SPRecovery menu, use the directional pad to navigate to “backup/restore”. Hit the gold, center button to select it. This will open a new menu with 4 options. For now, we will only concern ourselves with the “Simple Nandroid backup”. Select it at this time.
Once the process has begun, do not power off the phone or press any buttons. At the bottom of the screen, you will see a progress bar showing the progress of the system backup. In orange text, you will also see what is currently operating.
After a few minutes, the backup process will be complete. You will see “(done)” towards the bottom.
You have now successfully backed up your Droid’s system. Next, you will learn how to restore a backup you’ve made.
Step 3: Perform Restore
Navigate to the “backup/restore” menu until you see the 4 Nandroid options. This time we will select “Simple Nandroid restore (latest)”.
Once again the process is completely automatic. Just like in the backup, you will see a progress bar and informative text. After a few minutes, the restore process will be complete. You will see “(done)” towards the bottom.
Using “Simple Nandroid restore (latest)” is useful if you simply want to return to your most recent backup. However, if you want to restore to a specific backup out of a group, you will need to select “Advanced Nandroid restore”. The first menu option is “Choose backup”; select this.
