Synapse 4 ruined my Deathadder V2 and Razer doesn't even care

I have Deathadder V2 since 2020 which was well working until I download Synapse 4. It has upgraded its firmware and corrupted it, now the mice is not working anymore, and only detected as “CRP DISABLD” in peripherics manager.
This software has ruined my mice, and support is not even concerned, telling me that the mice is outside of warranty. Seriously, I had no choice to install Synapse 4 as Synapse 3 was not support anymore, and after that, I had no choice to update my mice firmware as it was done automatically.

 

Tell me how it is even possible Razer responsibility is not engaged there ?

 

Is someone has a solution to solve this as Razer support seems completly lost, spamming me with the same answer again and again.

I have same problem with basilisk v2 and we can probably only buy new one. I tried to find some solution but you can "update" firmware only when the mouse is detected correctly. Mine corrupted when sending profile to on board memory

I had the same issue with my naga left handed edition , when install chroma within synapse 4 

was your mouse behind a usb type c dock ? like mine ? cause i tought that might be the issue, with power instability maybe

that means the inside hardware has not enough protection for leveling power
