i have been using the deathadder v2 pro for 2 years, and now im facing a problem which is that my mouse keep disconnecting and reconnecting, i searched the web and found out i have to update the firmware to fix that.

but while updating the firmware, its leading to another problem. i found out that i need the dongle to update the firmware, and i lost it and now i cannot solve these two problem.

is there a way to update it without my dongle… because i can’t even play games normally right now.
