HOWTO restore Bluetooth functionality of ProClick?

Question

Hi there,The Bluetooth functionality of my ProClick mouse stopped working for no reason.When I move the bottom switch to Bluetooth mode, the LED starts blinking in pairing mode (on, on, pause) but the mouse cannot be detected by any Bluetooth receiver (neither on Windows nor on Linux)	The behavior is the same on all three Bluetooth channels (blue, green ,yellow)Mouse works fine in 2.4 GHz (with dongle) and wired mode.Firmware is on version v1.02.00_r1The purchase date was in 2020 so I fear that it is out of warranty. Still it’s pretty disappointing that such an expensive mouse suffers from such a malfunction.Any chance to resurrect Bluetooth functionality? Any tips are welcome.

I am very sorry to say, from what I can tell...no.

The Razer Pro Click suffers from a known, reproducible, and irreversible Bluetooth failure mode caused by corruption of the internal Bluetooth pairing table stored in the BT controller’s NVRAM. This memory cannot be reset by the user, cannot be cleared through Synapse, and is not touched by firmware updates. Once corrupted, the Bluetooth subsystem becomes permanently bricked, leaving the mouse functional only in wired and 2.4 GHz modes.
The only true fix would be for Razer to release a firmware or software tool capable of resetting or reflashing the Bluetooth controller’s internal memory.
As of today, no such tool exists.
This is a product‑level flaw, not a user mistake.
