9 people have this problem

- Uninstall the laest ewelink version.

- Install the oficial version of ewelink that you find in play/appstore.

- Start the app and NO upgrade in this moment.

- Now you can update the firmware device and when the work finish, you can upgrade the app too.


I hope I've helped.

I habe buy a dual sonoff , whit firmware 1.2.0. device is now registred on my acount working ok . but  it does not require update . say 120 is last version .

 

 

I hope the next one  helps for You all!


After 6 hours, spent trying to upgrage from 1.2 to 1.5  without any result - it stopped upgrading at 90% and said - it failed (I switched off alternative WIFI, pushed every possible buttons  in every possible ways, renamed device, upgraded, removed and installed eWeLink again...etc )
No result!!

Solution:

At the end I simply removed/deleted the  device from my eWeLink app (android),  added/paired the device again and...pushed upgrade, and it was upgraded at once - tadaa!

That's all I think...

Good luck! :)
