Hi - received a Sonoff Basic today. Initial setup was fine and I could control my device. When I tried to do the firmware upgrade to 1.8.1, it failed at 90% and now there are no lights on the unit. Have tried powering off/on without success. Still no LED.
Any tips?

I never had that, even though I also had it failing at 90%. Try to put the power on and then hold the button for a long time (let us say 60 sec). (but you probably already tried that)
