Rooting

DISCLAIMER: RootzWiki is not liable or responsible for any damages to a user's device. It is entirely the user's decision to "root" their device.

Unlock the bootloader

This procedure will wipe all data on your device's internal memory and void the warranty.

  1. Backup everything on your phone that you care about: Apps, settings, contacts, call logs, text messages, and so on. There are a variety of apps in the Market to assist with this.
  2. Setup the Android SDK on your computer.
  3. Reboot your device into Fastboot mode by powering off, then...
    Nexus One: Powering on while holding down the trackball and power button. You should be at a white screen with skating Bugdroids.
    Nexus S: Powering on while holding down Volume Up and power button. You should be at a white screen with skating Bugdroids.
    Galaxy Nexus: Hold all three buttons until arriving at a black screen with an open Bugdroid.
  4. Connect your device to your computer and open a command prompt, terminal, or shell on your computer.
  5. Run the following command:
    fastboot oem unlock
    Note: If you do not have the fastboot executable, make sure you followed the instructions for setting up the Android SDK properly. Failing that, you can download it for Windows and Linux.
    Note: On Windows, if fastboot returns with Waiting for device, download the Samsung USB drivers, install them, then right-click the "Android 1.0" device in Device Manager, select "Update Driver Software...", "Browse my computer for driver software", "Let me pick from a list of drivers on my computer", "Samsung Android Phone", "Next", and if given a choice of drivers, select the newest one and finish the driver installation. Aferwards re-run the fastboot command.
    Note: On Linux, if fastboot returns with Waiting for device, run it as root.
  6. On your device, a prompt will appear and confirm that you wish to unlock your bootloader, and warn that doing so will void your warranty. If you agree to those terms, press Volume Up to select Yes, and then the Power button to confirm.
  7. Your device will wipe its internal memory, and then reboot.
    Note: If it does not, use the volume keys to select the "Recovery" option. In Recovery, press both Volume keys and the power button simultaneously, use the volume keys to select Factory Reset, and power to confirm.

Install ClockworkMod Recovery

  1. Download ClockworkMod Recovery 6.0.2.5.
  2. Reboot your device into Fastboot mode by powering off, then powering on while holding down the volume-up and power button. You should be at the bootloader screen with Android in middle.
  3. Connect your device to your computer and open a command prompt, terminal, or shell on your computer.
  4. cd to where you downloaded ClockworkMod, and run the following command:
    fastboot flash recovery recovery-clockwork-6.0.2.5-crespo.img

Flash Superuser

  1. Download SuperSU 1.25 (Mirror) and copy it to the root of your sdcard (External storage) or Device storage (Internal storage).
  2. Reboot your phone into recovery mode.
    On most HTC devices this can be done via booting into HBOOT by holding the trackball or a volume button (usually down) and power after removing and reinserting the battery, then selecting "RECOVERY".
    On most Samsung devices you can hold Volume Up and Power from a powered-off state until you arrive at the custom recovery.
    On the Samsung Galaxy Nexus, hold both Volume buttons and the power button from a powered-off state until you arrive at the bootloader (black screen with an open-chest bugdroid), then use the volume keys to select "Recovery mode" then press power to confirm.
  3. Select backup and restore, then Backup. The backup will take some time to complete, so be patient.
  4. Select install zip from sdcard then choose zip from sdcard.
  5. Select UPDATE-SuperSU-v1.25.zip and confirm.
  6. Once complete select Go back until you return to the main menu.
  7. Select reboot device now and allow your device to reboot.
