Razer Deathadder v2 special edition mouse freezing after firmware update

I have had my razer deathadder v2 special edition for a while now, probably 3-4 years and I love it. I decided to update the firmware to the most recent version around the same time that i updated from razer synapse 3 to 4, maybe a week ago. Over the years the mouse had been working completely fine but now, every so often, it will freeze in place for 0.5-2 seconds. After the freeze, it seems to do all of the movement made with the mouse at once. The majority of the time its when im playing games but i have seen it happen just browsing.

Im not sure whether it was updating from synapse 3-4 or if it was the firmware update that has caused this. I am wondering if theres any safe firmware rollbacks/if this is a known issue with the deathadder v2 special edition. Any information/advice would help.

 

Some information:

  • I’m also having another issue with synapse 4 where I cant click windows icons if synapse is open. I have to close synapse to use my laptop properly.
  • I have tried deleting and reinstalling drivers.
  • I have a broken side button on my mouse which has been disabled for a long time in synapse. Before updating everything, the mouse worked fine even with the broken button.
  • I downloaded the firmware for RZ01-03210, even though my mouse it just RZ01-0321. From what I know the only difference is cosmetic but that could be what caused the issue.

Any help would be very appreciated!
