title: Android Things Raspberi Pi Not booting
body: <p>I'm new to Android Things, so would beg your pardon for any silly mistake.
  I'm using Raspberi Pi 3 Model B, and installed Android Things 0.5.1-devpreview on the sd card. But it's not booting. The board is fine as it's working fine with NOOBS and LIBREElec. When I start the board with Android Things it just shows the rainbow image of raspberi two times before shutting down.
  Please help.
  I've downloaded the zip from <a href="https://partner.android.com/things/console/#/622pn5/build" rel="nofollow noreferrer">https://partner.android.com/things/console/#/622pn5/build</a> and unzipped it (using fedora, so unzipped using Archive Manager), and Flashed the image to SD Card using <a href="https://etcher.io/" rel="nofollow noreferrer">Etcher</a>.
  I'm just unable to boot Android Things in Raspberi Pi, this problem doesn't includes any coding (but a development related problem), so I've not pasted any code here.
  Again beg your pardon for any stupidity as I'm new to Android Things.</p>
