My recently bought Razer Atheris from Razer store no longer works in Bluetooth mode suddenly. When switched to Bluetooth mode, the middle button LED does not blink at all and does not show up when searched. I’ve tried doing the three button salute to reset profile (LED also does not blink), reinserting fresh batteries, but to no avail. It now only works in dongle mode.
Is there any recourse (like opening it up to flash something), or this mouse is effectively toast?
