Before We Begin

Before we begin rooting you must have an unlocked bootloader. To unlock your bootloader, do the following:

Note: Unlocking your bootloader will wipe all data on your Nexus S and it may void your warranty. Proceed further at your own risk.

  • Make sure Nexus S drivers [3] are installed on your computer.
  • Install Fastboot and ADB [4] on your computer, if you haven’t already.
  • Shutdown your phone.
  • While the Nexus S is turned off hold the Volume Up and Power buttons simultaneously until the Nexus S turns on and is in Fastboot Mode. You will know your device is in Fastboot Mode when it says FASTBOOT MODE in red text at the top. Also the screen will list a bunch of information such as HW VERSION, BOOTLOADER VERSION, BASEBAND VERSION, etc.
  • Connect your Nexus S to your computer.
  • Open command prompt on your computer and type “fastboot oem unlock” without the quotes.
  • Accept the caution on your Nexus S’s screen.
  • Let the device work.
  • When it is done boot back into Nexus S until you see the home screen.
