Hello! I will make this concise.
I have a severe problem with my huntsman keyboard for over three years now, i’ve shelved this device with no hopes of ever restoring it back. Recently, i’ve tried to diagnose the problems again which are unresponsiveness, delay in the keys, repeating keys and the keyboard usually works in the first hour after plugging it in after a long time but it seemingly goes back to its bricked state. I am on the latest firmware though I vaguely remember Razer Synapse potentially causing this problem when I upgraded the keyboards firmware.
I did mostly everything available online like resetting the keyboard, reinstalling synapse and changing devices. I haven’t tried downgrading the software. Any help is appreciated.
