To open the OnePlus 5, you need a Torx T1 screwdriver. You can also work with a pentalobe screwdriver, although it doesn't fit right.

1. Remove both screws on the bottom edge of the case. They are located to the right and left of the USB port and the audio jack.
2. Place the screws on a common field of the magnetic mat or sorting box.

Remove the SIM card holder with a SIM tool or paper clip. Push the tool into the small hole on the SIM tray and pull it out.

The OnePlus 5 consists of a back cover and a display unit. All the electronics and the screen are installed in the display unit. The back cover is designed as a case.

To lift off the back cover you need a suction cup, a flat opening tool (like the iPlastix) and a pick. If the screen is badly cracked, cover it with a strip of packing tape so that the suction cup can stick.

1. Attach the suction cup over the home button. Pull on the suction cup and then slide in the iPlastix or a plastic pick between the display and the rear panel.
2. A small gap should appear. Here you can insert the pick. It is best to use a hard plastic pick with stopper, so that won't slip too far into the device.
3. Now slide the pick around the whole frame. You can twist the pick a little to lever off the display. The device is not glued, but clipped. Use the plectrum to release the clips one by one. When all clips are released, you can lift off the back cover. The clips at the upper edge come off last.
4. The back shell is still connected with a sensitive flex cable. Lift up the back cover and hold it to prevent damaging the cable.

3. Then disconnect the second connector. It connects the USB port to the mainboard.
