Keyboard RGB issue - Dell g15 UEL 2 bios dump

[slade1]

After a bios downgrade, the keyboard's RGB stopped working, now in the device manager the STM32 Bootloader device appears, I discovered that it is the rgb microcontroller, I believe that (STM32 bootloader) is because it does not identify the bios file (UEL2)

Does anyone have the BIOS dump (UEL 2) of the Dell G15? It is responsible for the RGB keyboard.

You need to program UEL1, programming UEL2 doesn't work. Have you tried with a new BIOS?

I just updated the bios, but without success.
in the bios update files, there is nothing related to the ELC firmware

You need to get it from another active device, or from the donor table. That's what I know.
