no possible to do an update of my firmware 1.7.0 to 1.8.0 from Ewelink
i got an error message : " Echec de la mise à niveau du firmware"
can you help me, what can I do exactly to do this upgrade ?
close this issue. seems to be no solution.
Hi the solution is to be at least 15 feet away ie in another room entirely when you initiate the upgrade and don;t use the wifi that the devices are connected to use your phone data , no idea why but i suspect the proximity of the phone messes the devices signal up or something , had this issue for months then tried in another part of the house and it works fine , upgraded 4 devices with no problems
Intenté actualizar 2 sonoff basic y 90% parado y luego dejé de trabajar. no se encienden, no hacen nada, muertos
I had the similar 90% issue. I turned off my WiFi on my iPhone so it was forced to use my cellular data connection and the update worked.
I attempted this on my iPhone by switching off wifi and attempting an upgrade and it did work for one device. But is not working for my other devices.
I found a solution. You simply have to stay on the "Settings" screen after starting the upgrade and not go back. If you wait a few minutes, it will complete the upgrade.
Sometimes it took me 2 tries.
