i tried a lot but not success. i delete device and readd and tried to upgrade. reset android software, but never success. i have 1+ sonoff pow. what sould i do?
I have same issue and I'm not able to fix it as well. Somebody something to add to this?
In the same boat, unable to upgrade from 2.0.4 to 2.6.0. After attempting the upgrade, the sonoff goes offline for a bit then comes back online and reports that the upgrade failed.
Error message states, "100022a077Upgradation failed, please retry"
As in, reboot the sonoff (kill power to it then turn the power back on)? My sonoff isn't actually powering anything at the moment, it's just used to measure temperature and humidity%.
Thanks though, I'll try this evening.
Thankx for the information, I was able to update the firmware. :)
Same issue. let me try by power off and on again
