ok, with lots of trying, I was able to get it to connect and update via “Bootloader” mode.
It now has “1460332895”
But it presented a new “challenge” of being stuck in “Firmware update” mode.
The app would see it as a “Mooshimeter” (aka not in “Bootloader” mode) and connecting to it takes a few attempts and it will bring up the “Firmware updater” screen.
Clearing the cache, resetting the unit, pulling the batteries to reboot it, all didn’t work.

What ended up working was for me to go to Android’s Settings, Apps, then do both a “Force Stop” and “Clear Data”.
