m16 R1, keyboard controller firmware

Since I got my laptop my keyboard was not working properly. Shortly after I entered my data in the Windows welcome system my keyboard was not answering. By my experience, Windows started updating itself, and some of the drivers and that changed the keyboard for some reason. It stopped working. 

I connected an external keyboard and finished the update process and rebooted the machine but the keyboard was still not working. So I went to the Dell support page and downloaded all the drivers that I thought were related to the keyboard. 

One of those were the firmware update for the keyboard controller. It was the "Perkey Cherry:FW13 1Zone:V0.2.4, A00" from December of 2023. When I was installing I noticed the driver asked what was the version of my keyboard. There were 3 options, per-zone, per-key and cherry-mechanical (if i recall correctly). I honestly didn't pay much attention and chose cheery and after that the keyboard started working again, but not perfectly.

1) Some of the RGB-lights of some keys don't work at all, some don't get some colors. I'm not sure, but some lights are brighter them other as well.
2) The multimedia functions are all messed-up: 

Mute Microphone => Mute Sound
Mute Volume => Lower Volume
Raise Volume => Raise Volume
Lower Volume => Mute Microphone

When u mute the volume and microphone, the respective correct key should light it up white, but that also its messed up. 

Mute microphone => lights the Lower Volume 
Lower Volume => lights the mute Sound keys


And now the final part and question (cause I already called support and they are going to schedule a replacement for my keyboard controller board) :

Cant I get a new firmware "cleaner" or something so I reinstall the firmware with the correct or adequate version of my keyboard ? The driver EXE file don't give the option anymore and just create some text file saying the update is correct/not-needed.

I think this is the cause of my problem. My keyboard is using a wrong firmware-system. Its a per-key-normal and not a per-key-cherry. 

Dell released a new firmware version after my initial problem, but it didn't fixed my problem.
