Hello everyone, I've tried all of the methods I could find online, without much success. I think there is a driver problem that just randomly occurred.

Basically, I was just using my pc after hibernation, and some of the keys didn't work. I could type qwerty fine, but spacebar/ctrl/alt/we - didn't work. So I've rebooted my pc and the keyboard stopped working altogether.

Firmware update doesn't end, it just fails after a couple of minutes, synapse 2.0 doesn't see my keyboard, there is no more Razer Blackwidow Ultimate 2016 device in the device manager, only hid keyboard.

Deleted all of the previous drivers, try to reconnect my device, nothing worked so far.
