Recover a device

If you've flashed a Production image from the Android Things Console onto your developer hardware or are otherwise unable to connect to your device using fastboot or adb, follow these steps:

  1. Connect to the serial debug console of your board.

  2. Connect power to the board. You'll see the following output from the console:

    U-Boot 2017.03-00545-gb47d6e0 (May 03 2018 - 19:05:06 +0000)
    
    CPU:   ...
    Reset cause: POR
    Board: ...
    ...
    
    Fastboot: Normal
    Hit any key to stop autoboot:  3
    
  3. Hit Enter before the countdown completes to access the bootloader prompt. Type fastboot usb and hit Enter:

    Fastboot: Normal
    Hit any key to stop autoboot:  0
    => fastboot usb
    

The board is now in fastboot mode. Follow the instructions to Manually Flash Android Things.
