    • First off, remove the magnetic cover and remove the 3 stock skates. You can reuse them if you pull them off carefully. Logitech skates consist of the actual Teflon skates and a second layer of foamy adhesive. Make sure you pull off both still attached to each other.

  2. WDfRsOP2UCCZEMdi

    • Remove the 4 screws.

  3. yDaDCQJS1oJULAYx

    • Start at the back and just clip the whole cover open. Don't be afraid to use a little force. Either use a clipping tool, or just use 3 fingers and your fingernails to grab into the gap and pull it off.

  4. Ga5E5n1qkyRNFbqk

    • Detach both flat cables and the battery connector.

  5. YtFkBt5kgI2xXCQh

    • Remove these 8 screws.

    • Next remove this screw (it's hidden deep, you will need a thin screwdriver to reach it)

    • And this one, This will allow you to remove the top LED cover.

  7. FZc31MAZUdNJGBel

    • Remove the LED cover and remove this screw to remove the LED cup.

  8. SVMMherQOUqLOUKJ

    • Remove these 4 screws which attach the 2 main buttons to the rest of the module. The right mouse button will fall out, while the left one will stay in place, just put the right one aside for now, you can leave the left one hanging loose. After removing these 4 screws, just pull out the whole internal module.

    Removing the internal module can easily be done by lightly pressing down on the mouse-wheel. The module should just pop out.

    • Pull out this plastic bolt which holds the scroll wheel module in place. I suggest you use something sharp to push at the bolt from the one end and pull it with your fingernails from the other side at the same time. It will require some force. After it's out, you can simply lift the whole scroll wheel module off the PCB.

    • When lifting the scroll wheel module, make sure you do not lose the 2 springs!

  11. La2wQP55UHbuTDPp

    • Remove these 2 screws and remove the scroll wheel holder.

  12. awGXtmjpPMKISOxo

    • Remove these 5 screws.

    • Solder off the Omrons and replace them with switches of your choice.

    You can make your life easier by removing (gently with tweezers) the bit of black tape covering the flat cable connector and removing the cable.

    Desoldering might be challenging. It becomes easier if you use nippers to cut the legs of the switches you want to remove as short as possible, making them flush with the solder. Use a desoldering pump to get rid of the solder. Adding a bit of fresh solder to the solder joints before trying to desolder might make it easier.

Thanks for the guide, i used some isopropanol to clean the switches instead of chaning them as i had a problem with the right one and now it works flawless.
