Unale to upgrade Pow R2 firmware

Ewelink app says new firmware is available. But when i try to update. it downloads for some time and it says unable to update. Tried several times. Anybody successful in updating?

I have the same problem.
from 1.0.0 to 1.1.0


I have 3 Pow. Two updated fine. One is always stuck at 90%. Overall I am seeing just below a 30% failure rate across Sonoff devices. Their tech support wasted loads of my time suggesting pointless things and now hasn’t replied in over a month. Essentially there is no warranty on their products. Don’t do anything they say unless they can explain a logical explanation why. I think they just have a long list which they copy and paste without thinking.

Hi, I have the same problem. Maybe there is classic Chinese politics, only sold and any support for costumers. Robert
