Pro Click Mini Bluetooth Unable to enter Pairing Mode

Thank you for sharing. Glad it worked for you. However doing a factory reset on my first PCM mouse, broke its bluetooth function completely, so I'm quite reluctant to try again. 

Thank you. 

I have found a solution to this issue, as long as you have an Android phone. If you still have an available color slot for pairing (for example, maybe your blue Bluetooth slot can no longer pair, but the yellow one can still enter pairing mode by long-pressing), you can use this method.

Simply put the yellow slot into pairing mode, then connect the mouse to your Android phone via Bluetooth. After that, just disconnect it, and you will find that both the blue and yellow slots have been restored to normal.

The inspiration for this came from a post on the Razer forum, where someone mentioned that their mouse suddenly started working again after being connected to a Linux computer. So I tried connecting the mouse to an Android device, and to my surprise, it worked as well.

This is undoubtedly a firmware bug from Razer, yet they have left it unfixed for years.

Thank you edie0922, I will try to pair one of the slot to my Android phone. It can still go in pairing mode while it's actively connected to something. In my case I've paired all 3 slots to Win10 and 11 computers. 

Appreciate your input :) 

I contacted support and Razer denied my warranty request for something which is obviously a firmware issue.

As I can’t use the dongle, the device is essentially bricked and now a 75€ paperweight.

This is my last Razer product.

I had the same issue with my first mouse and also the second mouse that was replaced with my warranty from the first one. It is simply a bad design and bad engineering of the mouse where the memory in the mouse cannot be overwritten for the 3 bluetooth slots (yellow, blue, green). Once it’s set to a device, razer did not design it properly to be overwritten on the same slot. I really wanted to like this mouse due to these awesome advertised features but this will be my last Razer product.

I have recently experienced this issue on my Pro Click (which I love!), and as an IT professional, I do not accept a lack of resolution. 
This is a permanent Bluetooth failure unless Razer provides a firmware‑level tool to reset or reflash the Bluetooth controller.
For all Pro Click customers awareness, I have provided a 'summary' of my deep dive into the issue, below. 

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.

Issue Presented
A Razer Pro Click mouse (RZ01‑02990) exhibits a complete failure of its Bluetooth pairing functionality. The symptoms are consistent, reproducible, and match numerous reports from other users:
Symptoms
- The mouse no longer enters normal Bluetooth pairing mode.
- Pressing and holding the pairing button results only in a fast‑blink LED pattern, which indicates the mouse is attempting to reconnect to a previously paired device — not advertising itself for pairing.
- Holding the button for an extended period (~60 seconds) eventually triggers a different, faster flashing pattern, but:
- No discoverable device appears on any laptop or phone.
- The mouse immediately returns to the broken state when the button is pressed again or the mouse is power‑cycled.
- The mouse functions normally in wired and 2.4 GHz dongle modes.
- The battery is healthy and holds charge for weeks, ruling out power‑related failure.
Troubleshooting Steps Attempted
All standard and advanced troubleshooting steps have been attempted, including:
- Removing all paired devices from host systems
- Attempting pairing on multiple laptops
- Resetting the mouse through Razer Synapse
- Updating to the latest firmware (v1.02.00_r1 — the only firmware Razer has ever released for this model)
- Cycling Bluetooth profiles
- Power cycling
- Extended button holds
- All Razer‑recommended troubleshooting steps short of battery replacement
None of these actions restored Bluetooth pairing functionality.

Likely Cause
**Corrupted Internal Bluetooth Pairing Table (NVRAM)
— a known and recurring failure mode in Razer’s older Bluetooth stack**
The Razer Pro Click uses a dedicated Bluetooth SoC with its own internal non‑volatile memory (NVRAM). This chip stores:
- Pairing keys
- Host profiles
- Last‑connected device
- Connection state machine
When this internal memory becomes corrupted — often triggered when a host deletes the pairing while the mouse is offline — the Bluetooth controller becomes stuck in a permanent reconnect loop and refuses to enter discoverable mode.
This failure mode has been widely reported across multiple Razer Bluetooth products (Atheris, Basilisk X, Pro Click Mini, Orochi V2), and the Pro Click exhibits the same pattern.

Rationale for the Likely Cause
1. The LED behaviour matches a reconnect loop, not pairing mode
The fast‑blink pattern is the Bluetooth controller attempting to reconnect to a remembered host.
A corrupted pairing table prevents the controller from switching into discoverable mode.
2. Firmware updates do not reset the Bluetooth controller
Razer’s firmware updater flashes only the main MCU.
The Bluetooth SoC’s NVRAM is untouched.
3. Synapse “factory reset” does not reset Bluetooth memory
Synapse resets DPI, button mappings, and onboard profiles — not Bluetooth pairing data.
4. Razer explicitly disabled Bluetooth DFU mode
The Pro Click’s only firmware (v1.02.00_r1) disables BT‑side DFU, meaning the Bluetooth controller cannot be reflashed or reset by the user.
5. The Bluetooth controller’s NVRAM is internal and not user‑accessible
There is:
- No external EEPROM
- No reset pins
- No exposed pads
- No way to short or clear the memory
- No CMOS‑style reset mechanism
The pairing table cannot be wiped by power cycling, firmware flashing, or any user‑accessible method.
6. The mouse’s behaviour after long button holds indicates a fallback state
The 60‑second LED pattern suggests the BT controller is attempting a failsafe initialisation but cannot complete it due to corrupted NVRAM.
7. All other subsystems work normally
Wired and 2.4 GHz modes are unaffected, confirming the failure is isolated to the Bluetooth controller.
Conclusion:
This is a firmware‑level design flaw in the Bluetooth subsystem, not a user error, not a battery issue, and not a mechanical failure.

Symptoms of the Likely Cause
When the Bluetooth pairing table is corrupted, the mouse will:
- Refuse to enter discoverable pairing mode
- Blink rapidly as it attempts to reconnect to a non‑existent host
- Fail to appear on any device’s Bluetooth scan
- Ignore pairing commands
- Fall back into the same broken state after long button holds
- Maintain full functionality in wired and 2.4 GHz modes
- Retain the corrupted state permanently, because the NVRAM cannot be cleared by any user‑accessible method

This is a permanent Bluetooth failure unless Razer provides a firmware‑level tool to reset or reflash the Bluetooth controller.
