The mouse kept coming up under my Bluetooth devices but it would fail to connect every time. I made sure it wasn’t connected to my other devices. It blew my mind when someone mentioned there was a pairing mode. 

Your welcome! Last year I had the same issue with the mouse, but this website saved me from going crazy. I am not sure if this was already mentioned in the instruction pages in the box, but I managed to find the website for the solution

WOW!!! this picture alone saved me from pulling more of my scalp hairs off. Thank you, thank you, thank you!!! I have looked everywhere and just doing this alone fixed my issue.

Unfortunately not. For now I’m sacrificing a usb port for the wireless functionality in lieu of Bluetooth. 

Did you manage to solve it?

I’m now having the precise issue the OP has.  I’ve used this mouse for years across several MacBooks with no issues whatsoever, although I probably did a nice clean device unpair/removal/reformat on the older Macs before adding to the new Mac.

My son came over the holiday and we played some games and I let him borrow the mouse.  He paired it on his Mac, and now I can’t use it, enter pairing mode or anything on my Mac.  The instructions to “press the pairing button on the bottom” are absolute dross, there is no button on the bottom.

I can get it to do the fancy blue ficker with what I can only assume is some diagnostic mode with the L/R/Scroll button combo, but that doesn’t help to pair it.

The DPI/4th/5th button combo does nothing.  No blinky.  No pairy.

Thankfully my son hasn’t left yet, so tonight I’ll try to see if he can remove the device from his bluetooth settings.  Elsewise looks like I might be tossing this into the recycle bin and shopping for a reliable mouse.

this website may help, but basically u should try pressing the two side buttons + dpi button. Also make sure no device is paired already with the mouse

Same exact issue on my Mac this morning, unsure of what to do.

For me didnt work . 
Using Mac M series. 
 

I have tried several ways (all listed here) without success.

I think Razr should speak out regarding this issue with the Mouse. We have several people with the same problem and we do not have a definitive solution. Many people are trying different ways (some succeed and others do not).

Razr Team, do we have an official position?
@Razer.Zionzedd could you help us?

To ANYONE who runs into this issue - All you need to do is go into bluetooth pairing mode - this is confusing because this mouse has TWO bluetooth pairing modes. One is activated when u switch into bluetooth mode with the switch on the bottom, the 2nd, and much more robust pairing mode, is activated when you hold down the two side buttons, and the DPI button! this will make the mouse blue light blink rapidly and it will successfully connect to any device. 

Hi guys, 

Out of the blue my 1st gen (RC30-031501) mouse stopped working on BT. Same behavior as all mentioned: no blue LED flashing, no activity when pressing the pairing mode combination of buttons.

Anyone managed to find a solution? 2.4Ghz is not an option for me as I’m using it with a MacBook which only has USB-C ports.

Thanks 

to fix this make sure the mouse is not paired with any devices. Then put the mouse switch onto bt  (Bluetooth) mode then start the search for bt devices on your pc , after that press the dpi and both side buttons in the order dpi, button 5, button 4 keep all 3 buttons pressed DO NOT let go of them when the blue light starts to slowly fade lower and brighter look through the list of devices on your pc find  basilisk x try to pair with it all while still holding down the 3 buttons and the blue light is still fading then your pc should pair the mouse again and say ready to go.

Hi, I’ve found a solution for my laptop running Windows 11 (23H2). My Intel network card (AX210) has given m some headache with the bluetooth pairing of the my Razer mouse (Razer Basilisk V3 X HyperSpeed). I have already installed, updated, configured the Synapse software because I already had a Razer Naga Trinity, so I was very familiar with the software.

So after I’ve installed all the most recent driver from the official website of Intel, I also removed any power saving features from both wifi and Bluetooth, because I read in can cause problems on some machines (maybe I will enable it again in the future specially for a laptop).

After that I rebooted my machine.

I also detached the battery power with a needle to achieve the same results, like in this article (https://www.intel.com/content/www/us/en/support/articles/000090393/wireless/intel-wireless-ac-products.html) because I wasn’t sure what the were the problem was, so I tried anything possible.

After all that I found in windows setting, in the section “Bluetooth & Devices > Devices” the subsection “Bluetooth devices discovery” for me it was set to “Advanced” and I set it to “Default”.

To be sure that it remains active in the pairing mode, I followed the instruction from the manual, briefly… the right buttons combination.

After that I was able to connected successfully.

-

P.S. My network card (MediaTek Wifi 6 MT7921) on my desktop with Windows 10 (22H2) it gives me zero errors from the first time, so it depends maybe on the drivers, manufacture, etc… I really genuinely don’t know.

I also typed very recently this 2 commands on CMD, for my other reason. But those should clear systems error.

1) dism /cleanup-image /online /restorehealth

2) sfc /scannow

Yes, buying Razer is a regret. I'm having the same problem. And also Razer's support system doesn't work well either.

both my 2.4g and BT connection spoiled… any mode i switch on will make the cursor snap to the bottom of the screen and to make use of mouse on my pc have to switch of razer basilisk the use old wired mouse. if razer still turn on in anymode will make my cursor just at the bottom of the screen and cannot be move… i want my money back… already 13 days and all the troubleshoot with razer team via email also not helping… 

Problem solved in order to add DFUBasilisk bluetooth during the firmware update process you have to switch Bluetooth pairing mode from Default to Advanced in Windows 11 settings.

Hi, i have a similar issue.  I can connect via bluetooth just fine - but i can’t update the firmware.  Stuck on this screen.  I’ve tried 2 different PCs.

Is there any info on that? Or a chance to get support?

Or do we have to open a return case? I am in contact with the retail. I will return it if there is no solution. Blutooth is dead for over a week now. I cant use the mouse with Blutooth anymore.

I got the same problem now. BT is not working anymore. I am only using BT on my SteamDeck so there is not additional Software in use.

Synapse and Dongle are used on my Notebook. That is still working. Its only BT not working.

Its a Razer Basilisk X Hyperseed

RC30-031501 Gaming Mouse

This is a bit frustrating. I can go into the mode where I hold the left and right click combined with the mouse wheel. It goes in a rapid blue LED blinking and on a PC i can see “dfubasilisk” but nothing is working. SteamDeck cant connect to the mouse and its shown offline all the time. I removed it but I am not able to reconnect it in any way…

Do I have to send it back? it’s quite new.

I was having the same issue, it wasn’t going into pair mode. I didn’t try it for about 4 months, now it goes into pair mode.

It’s likely that several months ago this mouse was connected to my other laptop, and that’s why it wouldn’t go into pairing. Well, I reformatted that laptop so now that it’s going into pairing it just can’t be found.

I have made sure all bluetooth settings on my laptop, tablets, and phone that I’ve tried to find the mouse with are all set to discoverable and the mouse just can’t be found.

The fact that you can’t clear device connections from the mouse with a combination of buttons being pressed is absolutely absurd, the fact that once you somehow manage to get it into pair mode (barring you didn’t sell the laptop it was connected to, otherwise you’d be shit out of luck) it just simply can’t be discovered demonstrates that this mouse has significant hardware/design issues.

I’ll be sure to steer people away from Razr mouses. If they can’t design a mouse appropriately then why would I trust a Laptop or any other product?

OMG!!! I finally did it.

I had to do the following to get this to connect.

I would follow what the other posts advised to make sure it is not connected to another device. I had it once connected to a mac and even after pressing “forget” it would still connect. To completely negate the mac I pressed “forget” the device than shut down the mac.

On the PC you are trying to connect to, I would start the Bluetooth search for the mouse. On the mouse itself I would toggle the switch to off → press the DPI button and both side buttons → while holding down the these buttons toggle the switch to bluetooth (BT). Keep holding down these 3 buttons and I got the PC to find the Hyper X. The tricky part is that you have to keep holding down these buttons on the mouse while you select the icon on the PC. I had another mouse hooked up to help with this. Hopefully for you it will say that device is ready.

Good luck!!! 

@Voltfrontspaceship895, it is just as polydepotPuceRed530 wrote, you need to disconnect it from the previous connected device. If you don’t have access to the previous device, the bluetooth mode is dead.

edit: this is a very bad design! @Razer.Zionzedd we need a way to restart bluetooth!

I have the same issue, did anyone find a good solution? or is this mouse not a mouse to recommend to someone else?

I am having the same issue. I’m using MacOS. After I “Forget My Device” and try connecting again the mouse can connect via Blutooth again,
