Won't start again after upgrading

Hello, I've received 2 units of Sonoff right this morning. I've connected the first one, and the Android app recomended to upgrade its firmware. I agreed, and it started to upgrade. After a good amount of time, nothing happened, both in app or the sonoff, no signs of upgrade finished.

I turned off the Sonoff device, and turned on again, but now it won't start. No lights at all, appears as offline from the App. I don't know what to try. I screwed it up?

I also have the same problem. Remote is just lighting but not working. I think they did it on purpose for you to buy a new one.
