wireless solutions not working on my deathadder V2 Pro

I’m a bit more lucky, wire and BT working fine (for now), but I have the same issue with 2.4 dongle

there was a solution with a firmware updater, but it can’t see the dongle, so this is a dead end

when I connect the dongle to my PC, the device manager updates a bunch as if it’s connected, but in fact no new devices appear, just 2 Razer DeathAdder V2 Pro HID devices with 02.01.2017 and 21.01.2021 drivers, which appeared from the first plug-in of the dongle

so when you put it in BT and press the three buttons the mouse start flashing blue and shows up?

if you have your mouse connected with cord and put it to 2.4 and then remove the cord, it "kills" the mouse?

dunno what the problem is. wireless usually works 100% fine with other mice. no pairing etc. the weird thing is that i connect both the mouse and dongle and run the program that says it's paired and fine. except it doesn't work. 

when I put it in BT it goes straight to flashing blue, I don’t have to press three buttons

if by kills you mean it stops working then yeah xD

guess mine is f'd then 😑
