3 people have this problem

I have tried updating from IPhone and Android. I have also tried deleting and re-adding the device and then updating. Also tried from hotspot. Still no luck. Maybe server issues. I don’t know. Any other advice anyone?
I’ll just not update after reading these. Mine are v1.6 and work without a problem. I have seen no explanation of any benefit to an upgrade. Only problems after upgrading. Has anyone upgraded and seen any benefit from it?
I was hoping it would fix the issue of frequent disconnections from the server every time I give a command to these devices.
Same problems as everyone else. Cannot upgrade firmware to 1.8 from 1.7. Stops at 90%.

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

Oh wow. I haven't tried that. Thanks for the suggestion. I'll give it a try tonight and get back to you.

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.

check if you have connected input live and neutral wires properly. then if you have the firmware to 1.6.0 then use compatible AP mode by pressing the sonoff button for 5 secs and again for 5secs until you get fast bkinking green light. then update the device then dete it and add it again in simple touch mode... that will do the job :) follow the video below...

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.
