So I got a cheap used G502 under the pretense that the USB was busted and while it would charge, on wired mode it would not work, windows would not recognize it, or even give the little jingle when plugged in... but it would charge.

So I think "ok challenge accepted, it's probably that the data bus on the usb is busted. I solder in a new one and I get a cheap wireless G502 that I've been wanting for years!"

Nope, wireless doesn't work either, G-hub detects the dongle but that's it, It turns on but it doesn't pair with the dongle, it's like the firmware is stuck in some weird infinite loop. The battery indicators are always on and the Logitech logo light is always off. Switching it on and off does almost nothing as well, all it achieves is flickering off the battery indicators for a split second before they turn right back on. If I do it quick enough then maybe the logitech logo light will flicker on for just a nanosecond.

I opened up the device to see if I could figure out what I'm dealing with, here are pictures:

So yeah, and since it's second hand I doubt Logitech is gonna let me RMA this. Any ideas?

As far as I can tell the button daughterboards seem fine btw.

Both no longer have a physical click when pressing the wheel (which I use as a double click). I have opened one of them to see but can't find what causes the click which use to require a little bit of pressure to press the button. Now both can click with almost no pressure at all.

When wont work anymore, I start to blow air on the wheel and the scroll starts for a little bit to work but note the way that he should be working, and after few minutes, no more scroll again.

I am confused, I don't know what to do, I disassemble the mouse, clean it up, and still the some situation. Before the whole nightmare with 45 % Battery he went off and wont start for a few minutes, after he started the whole thing happens.

Help guys, please, maybe someone had the same problem, or maybe someone repaired one and know what this is about .

Thank you.
