Firmware update fails in IOS Kasa App - LB120 Bulb
Firmware update fails in IOS Kasa App - LB120 Bulb

Hi.  I have a new LB120 bulb and the IOS Kasa app is telling me it needs a firmware update.  However, every time I try the update it fails.

 

Updates work fine with smart plugs on the same app.  

 

Is there another way to update the bulb outside of the Kasa app?

 

Thanks.

You can refer to the following FAQ for some help:

Can you try to use another device to download Kasa APP and upgrade the firmware for a try?

 

Merry Christmas!

Hi.

 

The current firmware is version 1.2.3 - Kasa wants to update to version 1.8.6.

 

I have tried the Kasa app and update on an android device but the update fails there as well.

 

Thanks.

I am having the same issue.. I have reset the bulb, I have tried forwarding port 9999 to the buld which I saw in another post but still it will not update the firmware.. Message I get is "Update Not Complete, One or mre devices failed to update. Please try the update again".. No matter how many times I try it will not update..

 

Current firmware is 1.2.1 and the version it is trying to update to is 1.8.6.
