    Logitech G203 Prodigy Gaming Mouse

    Hello guys, my mouse left click started to double click,

    I unsoldered side click and swapped it onto left click, everything was great, but I was left with only 1 side button click, instead of two.

    Then I found another switch from other mouse and I got an idea to solder it back onto thumb button, so everything would be working properly.
    This is where things went south, pretty fast.

    When I was soldering it, apparently I burned the pads, so I tried to bypass them following the path.

    (pictures uploaded below, basically I connected two purple pins together), but then even click 1 thumb button when I clicked it it shut off my keyboard.

    So I unsoldered click2 on thumb and still left click on thumb button when I clicked it it shut off my keyboard, I couldn't use it anymore. even if it was not touched returned to factory new state.

    So I ended up having thumb_click board removed...And I wanted to ask if someone have like boardview for this mouse, to see how I could connect switches. Below I uploaded pictures, my question is, purple circle pins (NC Terminal), where do they connect? I thought its ground so i wanted to grind on board to find it but I couldn't.

    also could it be cause of me connecting NC terminal on both clicks to cause some short on board to make my keyboard not functional when I click that click1_thumb_button?

    Its little bit confusing I wrote plenty of things but hopefully you guys can understand what I tried to say, and if not, feel free to ask me thank you for reading!

    The purple pins are not connected, there is no need to bridge anything.
    Fit the switch and bridge between the trace and pin of the switch.

      Yes that's what confused me, what are purple pins used for, if they don't have trace?

        If they don't have a trace then nothing.
        There are only 3 connections. Common ground and one each for switch activation.

          Fixed! Maybe its not the prettiest, but it works as new, and no one can see it! Thank you very much for helping me!

            Nice, maybe add a dab of hot glue to help secure the switches to the PCB.

              I used superglue, my fingers are still sticky xd its invisible on camera but its there, it has nice two screws that hold it in place and side buttons also hold it in place, it cannot escape anywhere hehe but yes, works perfectly
