My blackwidow RZ03-01220200 keyboard has stopped working and razer won't help me

I've had this keyboard from Razer for a while, and it's been working fine for a while, however when I picked it up to clean, my computer no longer recognizes it as a keyboard, it identifies the keyboard as "Razer Bootloader", and after looking for solutions I found the solution to download the keyboard firmware, but I didn't find a firmware available for my keyboard model, because it is an old model. And after trying to contact razer it said that I would have to pay for support, in a case that the solution is theoretically simple. So that's why I'm asking for support here... Does anyone know how to help me?
