the phone came out dec 2019, which is also the month of the first tag,
   so they all could be relevent.
   I had fastboot installed to an external drive which had powered down.
   thankfully, it powered back up.
   I was downloading the latest tag with links, but links seems to have
   mostly frozen up, responding to only intermittent keystrokes. it makes
   sense to just use curl (aside from that severe concern)
