Use this guide to install a new DVD Drive for a Nintendo Wii U.
Step 1 Console Outer Case
With the bottom of the console facing up, remove the following 6 screws hidden underneath the white square stickers:
Three 5.1mm Phillips #000 screws
Two 6.1mm Tri-wing Y0 screws
One 13.2mm Tri-wing Y1 screw
Rotate the console 180 degrees so that the exhaust vents are facing you.
Remove the two 7.1mm Phillips #00 screws.
On the side opposite of the exhaust vents, slide the cover faceplate towards the back of the console and pull upwards to release it.
On the bottom of the console beneath the previously removed faceplate, remove the three 13.2mm Tri-wing Y1 screws.
On the back of the console, lift up and release the main top cover.
Step 6 Front Faceplate
Rotate the device so that the front plate is facing you.
On each side of the console, remove the 3.5mm Phillips #0 screw connecting the DVD drive to the faceplate.
Rotate the device so that the front plate is on the right side and the ribbon cable is visible.
Lift up on the blue tab to release the ribbon cable.
Remove the front faceplate.
Step 9 DVD Drive
On each side of the DVD drive, remove the two 4.6mm Phillips #0 mounting screws.
Rotate the device so that the DVD slot is visible.
A ribbon cable is attached to the bottom right side of the DVD drive. The ribbon cable can rip if it isn't removed properly.
Lift the DVD drive out of the mount and turn over to the right so it lies like a book.
Use a spudger to release the ribbon cable.
Remove the CD drive.
