I left that system downloading the factory system image overnight.

   Meanwhile, the OTA firmware updates drive was private, and this morning
   my request for access was granted.  I just said I had the phone new and
   wanted to set up for flashing it.
   I'm trying out the gdrive client now
   ( [1]https://github.com/prasmussen/gdrive ) and running into a simple
   and abnormal network error:
   $ ~/pkgtmp/gdrive list
   Authentication needed
   Go to the following url in your browser:
   [2]https://accounts.google.com/o/oauth2/auth?access_type=offline&client
   _id=367116221053-7n0vf5akeru7on6o2fjinrecpdoe99eg.apps.googleuserconten
   t.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&response_type=co
   de&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&state=state
   Enter verification code:
   Failed getting oauth client: Failed to exchange auth code for token:
