DeathAdder V2 CRP DISABLD after Synapse 4 / possible firmware issue — Case

Hi

I’m asking here because I saw that some firmware-related mouse issues were helped/escalated through Razer Insider before.

My Razer DeathAdder V2 suddenly stopped working after I was using Razer Synapse 4. The mouse was working before, but now Windows only makes the USB connect/disconnect sound. It does not work as a mouse, it disappeared from Synapse, and in Windows devices it appears strangely as a drive/device instead of a normal mouse.

What I already tried:

  • Tested it on another computer

  • Tried different USB ports

  • Checked Synapse, but the mouse no longer appears there

  • Contacted Razer Support

  • Sent proof/video of the issue

My support case number is: (removed for security purposes)

Support told me the product is out of warranty, but this does not feel like normal wear or physical damage. I have taken good care of this mouse for years, and it was working normally before this happened.  That is why it is very frustrating to see it become a brick after using Razer’s own software. It looks more like a firmware/bootloader issue, because the mouse was working before and then suddenly became detected incorrectly after Synapse 4.

@Razer.sushi.boi, sorry for tagging you, but I saw that you helped other users with similar firmware/RMA cases. Could you please check if this case can be escalated or reviewed for firmware recovery/RMA options?

Thank you very much.
