Can't update mouse firmware

I have a razer deathadder v2 pro wireless. It was working wonderfully until recently when it started disconnecting and reconnecting constantly. I can barely get a click in.

I saw someone recommend updating the firmware and I was able to update the dongle (Which was connected through the microusb cable so I know its not the cable) but when I took the cable and connected the mouse to the pc the mouse wont stay connected enough to allow a firmware update. I constantly hear the windows connect and disconnect noise.

I tried uninstalling the drivers through device manager but it didnt help. I also tried holding the profile button down for 10 seconds to reset the mouse to factory settings and it did not work either. I quit synapse and made sure windows was updated too. It happens on wired and on 2.4ghz. Bluetooth just says driver issue in the windows bluetooth even though I have uninstalled the driver several times.

Thank you for any help.

You can try clean-install Synapse:

Uninstall Synapse
Download & run this tool: to remove any razer drivers/leftovers
Then restart your PC
After reboot install Synapse again (as administrator).

You can also try to update FW on another PC (without synapse installed).
Found this thread and followed the steps to remove Synapse and reinstalled. Reinstalled as admin and as normal user, tried to update on another computer without synapse installed. The mouse acts like the battery is low even though it would report as 80+% when recognized. I'm going to see if I can let the mouse drain to 0% and try again but I am not confident it will work considering on USB the system would connect to the device and then lose the device every second or so via Wireless, USB, or Bluetooth.
