Step 3

Remove the four 6mm screws by using a JIS #1 screwdriver.

Step 4

Separate the top mouse housing from the bottom mouse housing using the opening pick.
Be careful not to tug too hard on the ribbon connector.

Step 5

Unlock the ribbon connector that is held down by the main board clips using the spudger's pointed end.

Step 6

Remove the side housing using the opening pick.

Step 7

Remove the top housing LED 3-Pin connector that is near the main board.

Step 8

Remove one 4mm black Phillips #000 screw from the left side of the mouse holding the scroll wheel LED controller board.
Then pull the LED controller board upwards and out.

Step 9

Pry and remove the scroll wheel feedback bar from its hold-down clips using the hook end of a halberd spudger.

Step 10

Remove the scroll wheel feedback bar from the scroll wheel by holding down the spring and using angled tweezers to remove it from its placement.

Step 11

Remove the scroll wheel optical encoder 3-pin connector from the main board by wiggling the connector upwards.

Step 12

Using the opening tool, pry the black bracket holding the scroll wheel in place backwards until the scroll wheel housing pops out.

You don't have to remove that part, if you're careful you can leave the mouse wheel attatched to the mainboard because it's pretty fiddly to get the feather inside again.
