Does anybody have some insight on how to fix this issue? I've attached a text document called mesaage thats generated when I try to run the update. Currently have no RGB/Keyboard Lighting and would really like to not have to send it to lenovo to get fixed, leaving me without a working computer for likely a couple of months.

Was anybody able to find a fix for this. I have the same issue. Vantage recommended an update to the keyboard lighting firmware and now my lighting does not work. I tried all the  keyboard lighting updates posted on other forums but they fail to install completely, tried the lenovo nerve center,  checked the bios serial and MTM and looks fine. I have not been able to find a solution. Frustrating!

Re:Legion Y740 15ICHg Keyboard Lighting Firmware Issue

Exact same issue for my Legion Y740-17IRHg. I even went through all the troubleshooting steps on the Lenovo support site with an online technician. The online technician told me to keep an eye on these forums for a fix, and/or a technician can come to me which sounds like will do the exact same things I just troubleshot. I declined for now because of how busy I am at work and hestitant to have anyone enter the family's bubble while it's COVID season. 

 

I notice it's not only the keyboard lighting that stopped working, but the lighting on the back cover for the legion logo does not work as well. I do notice the power button light up blue when it needs to.

 

If you try to update the firmware for the keyboard lighting the install quickly states device is not detected and closes the window. Even the iCUE that manages the settings for the backlighting can no longer detect the device.

 

I use this laptop for work so I'm kind of stuck with it as it doesn't stop me from working, but annoying to know that something you put a lot of money into appears to be breaking down within the first few months. Hoping whatever is causing this issue doesn't snowball into bigger problems.
