We extract the eight Phillips screws (PH # 00) that hold the rear housings.

Remove the back cover of the blue control with the help of a fine tool, disconnect all components, and remove the two Phillips screws (PH # 00) that hold the side buttons to work with greater comfort.

We will do in the red command the same as we did in the blue control in the previous step.

We take off the vibrators.

We removed the bluetooth antenna.

We remove the four Phillips screws (PH # 00) that we indicated in the first picture, but in the blue control we will have to take off the battery since as we showed in the fifth picture, under the battery there are four other Phillips screws (PH # 00) that hold the intermediate housing. Now we can disconnect the flexes that the rear buttons and remove both covers.

In the blue control, we must disconnect the flex from the rear buttons to be able to perform the next step more comfortably.

Finally we can disconnect the side buttons that we have to replace.

It is not necessary to remove the joysticks.
