I’m looking for any sort of firmware update for my keyboard and it just doesn’t exist on the razer website, the closest model number i’ve seen is RZ03-0219x but when attempting to download the firmware for that it doesn’t detect the device. 
Does anybody know a firmware update for this specific model of the blackwidow chroma TE that apparently only exists in the void?
Edit: Just to explain why if it isn’t a surprise to you, i’m having the repeated key press issue and i’ve tried about everything BUT firmware updating but cannot try that for reasons stated above :)
