Hi, @abundance,
I’m also not nearby, but just wanted to point you to my post about my re-flash experience, which turned out to be relatively easy:
But how easy it might be for you depends on how familiar you are with Linux, and whether you’re using the latest Ubuntu version or some other OS.
If you’re not experienced with Ubuntu, Linux Mint, Debian, etc., but have a friend nearby who is, then I’m sure they could easily help you do the re-flash.
