Having issues seeing GLASS in Fastboot [closed]

Answer 1

You can use a hardware technique to get your Glass into fastboot. Make sure your device has some charge (15% or more should be sufficient) and follow these steps.

1. Power down your device by holding the power button for 15 seconds.
2. Press and hold the camera button. Keep holding it until step 5.
3. Briefly press the power button.
4. Wait until the LED solidly illuminates.
5. Release the camera button.

Now your device should be visible to fastboot. Plug it into a USB port and use fastboot to list devices:

$ fastboot devices

If your device is listed, you can now run other fastboot commands.

Answer 2

This issue on OS X, https://code.google.com/p/google-glass-api/issues/detail?id=243 is still not addressed (please star the issue while there), it still exists post XE8 regardless of how you start fastboot which as noted, times out and will reboot after inactivity of just a few seconds. Part of the problem is that the USB vendorId switches between Google and TI when switching between adb and fastboot (bootloader) modes.

The solution for Windows:

In android-sdk\extras\google\usb_driver\android_winusb.inf

Add to both the [Google.NTamd64] and [Google.NTx86] sections 2 additional lines:

;Google Glass
%SingleAdbInterface%        = USB_Install, USB\VID_18D1&PID_9001
%CompositeAdbInterface%     = USB_Install, USB\VID_18D1&PID_9001&MI_01
%SingleBootLoaderInterface% = USB_Install, USB\VID_18D1&PID_9002
%CompositeAdbInterface%     = USB_Install, USB\VID_18D1&PID_9002&REV_0100

Then from ControlPanel->System->Device Manager confirm the VID and PID values with the yellow warning tagged device or “unknown device” - if not the same, edit to match these values.
