Same problem here, cant find this alleged 2.50.3.0 version for download… link points always to old updater. Thanks for supporting.

Me too. I downloaded the HyperFlux V2 firmware updater, but since I don’t own the charging pad, it won’t run. I extracted the files and see Basilisk V3 & 35k files in there, but I don’t know how to apply it manually & don’t want to brick my mouse.

Hello mods, can you please share link to:

 

 

Keeps finally pointing to old version and as mentioned by SnakeFist85 I also don't have Hyperflux. I do have  Razer Mouse Dock Pro and it would  be nice to finally have it turned off lighting when monitor is turned off working… waiting for over a year to this basic fix...

 

 

 

Also the beta is exited every time I resume from sleep mode… really sad to say basic functionality not working in any version 3, 4, beta...

Thanks for hopefully one day releasing a working product.

It got so bad with Synapse 4 I had to add a scheduled task that would force Synapse to run on login and run Restart on Crash to force-close the process if unresponsive & relaunch it. 

 

I love the Basilisk’s feel and features, but it’s really held back by the software.
