Flashing instructions

Flash Tool

Android Flash Tool allows you to update the firmware on your Glass device. Click "Flash" next to the firmware you want to install and follow the instructions displayed on the screen.

For more information, see the Android Flash Tool Overview.

Note: USB Debugging and OEM Unlocking are enabled for the Glass flashing process, which allows you to move directly to step 2 after you complete the Flashing Tool instructions.

Note: If the Flash Tool asks you to reselect the device, reload the page and start the flashing process again. Don't interact with the device unless instructed to do so.

Manual flashing

Note: Flash Tool is the preferred method of updating the firmware on Glass device. Manual flashing instructions have been kept for reference only.

Glass flashing follows the procedures of standard Android flashing.

Before you begin:

• Make sure Android Debug Bridge (adb) and fastboot is installed on host computer. You can download it with SDK Manager (recommended) or directly from here.
• Download and unzip the build.
  Note: The zip file of the build contains the files you need in order to flash the device.

To flash a system image:

1. Connect your glass to your computer over USB.
2. Start device in fastboot mode with one of the following methods:

   Using adb tool

   1. Check for Glass, and only Glass, with the following command:

      adb devices

      Note: If you see more than one device listed, unplug the others or select the Glass device that matches the serial number of yours. More information is available in our How adb works documentation.

   2. Put the Glass device into fastboot:

      adb reboot-bootloader

   Using physical buttons

   1. Turn off your Glass EE 2 device.

   2. Press and hold the camera and power buttons for three seconds until you see the following text: “Press volume key to select, and press the power key to accept.”

      Note: In the bootloader, the camera button acts as volume down. You press the power button and the camera button simultaneously to get into the bootloader. The camera button continues to act as volume down in the bootloader.

3. After device boots you should see the fastboot screen and the device should list with the following command:

   fastboot devices

4. Once the device is in fastboot mode, follow the instructions from the README.txt file, which can be found inside the downloaded system image archive.
