Not all variants of this mouse require the mouse feet to be taken off for disassembly, but their removal is detailed anyway.
Carefully remove the feet of the mouse with an opening pick.
Keep track of the mouse feet, as you'll be reapplying them at the end of the guide.

Step 2

Use a Phillips #0 screwdriver to remove the 10mm screws on the bottom of the mouse.
Once all screws are removed, use the plastic opening tool to gently pry the mouse apart. This shouldn't take much force.

Edit

Step 3

Once the mouse is opened, locate the USB cable's 5-pin connector, which is plugged directly into the mouse's mainboard.
Take note of the position and route that the USB cable takes before removal. The replacement cable must follow the same route when inserted.
Using a plastic opening tool, gently remove the 5-pin connector from the mainboard.

Step 4

Take the replacement USB cable and connect it to the mainboard.

Edit

Step 5

Ensure that the 5-pin connector is fully seated into its slot on the mainboard. You may want to use a spudger to apply pressure onto it.
Using a plastic opening tool, route the cable through the case in the same way that was noted in Step 3.
