16 steps

Removing the SIM card tray
First turn off your OnePlus One.

You can use the SIM Tool or a paperclip to remove the SIM card tray. Press the SIM Tool into the small hole in the SIM card tray to remove it.
Removing the back cover
Insert a thin, flat, tapered spudger into the gap at the corner of your smartphone. There are several clips on the outside under the back cover. You have to disconnect them by moving the spudger around the entire smartphone one time. Alternatively, you can detach the back cover using your fingernails.

Then you can take off the back cover.
Removing the plastic cover
Remove all 15 Phillips screws that hold the plastic cover in place.

2 Phillips screws are hidden under a rubber cover. Use a sharp object to lift out the cover.

Now you can remove the following screws.
4 x 3.1 mm Phillips screws
2 x 3.1 mm Phillips screws (small)

Lift out the speaker cover. Carefully insert the pointed tip of the ESD spudger into the USB port and lift the black cover.
Removing the battery
If your OnePlus One is still on, turn it off now by holding down the standby button for about three seconds and following the prompt on the display.

Now you can detach the battery connector. Be very careful. Place the pointed tip of the spudger very slightly below the contact and carefully lift it up. The pictures show where you should put the spudger to avoid breaking off the little resistors even if it slips.

Now lift the battery with the spudger and then remove it.
Removing the speakers
Insert the flat end of the spudger below the cover at the level of the charging port and carefully lift the cover. The stereo speakers are under it.

Now you can remove them.
Disconnecting the antenna cable
ZFirst you have to remove the two black stickers on the side. You can easily pull them off with a pair of tweezers.

Now you can disconnect the antenna cable from the connector using the pointed tip of the metal spatula, and then remove it.
Disconnecting the buttons
The standby button and volume buttons are attached to separate ribbon cables, which are soldered onto the logic board.

Using the metal spatula, detach the cable, which is lightly glued to the frame.
Disconnecting the connectors on the logic board
Now you can disconnect the following five connectors. Be very careful.

Place the pointed tip or flat end of the spudger very slightly below the contact and carefully lift it up. Make sure you don’t break off the resistors/coils that are soldered onto the logic board.

Removing the logic board
Please remove the little screw close the camera connector Achte darauf, die kleine Schraube unterhab der Kamers zu entfernen.

Now you can carefully lift the logic board using the spudger and remove it by hand.
Installing the logic board
Now put the logic board back in the frame.

Make sure the cables don’t get under the logic board.

Use the picture to check whether your logic board is positioned correctly.

Insert the little placeholder on the display connector.

Reconnect all the connectors to the logic board.
Installing the buttons
Install the standby button and the volume buttons again. Use the spatula to press them into the appropriate positions.
Connecting the antenna cable
Now guide the antenna cable back through the little opening and connect it securely to the logic board.

Then put the adhesive strips back on.
Inserting the speakers
Now install the cover with the stereo speakers and put them back in the appropriate positions.
Installing the battery
Put the battery back in and connect it.
Attaching the plastic cover
Now put the cover back on.

Then fasten all the Phillips screws again.
12 x 3.1 mm Phillips screws
2 x 3.1 mm Phillips screws (small)
1 x 3.1 mm Phillips screw

Don’t forget to put the little rubber plugs back in.
Attaching the back cover
It’s very easy to put the back cover back on. Put it on in the correct position and press it on all the way around the phone until it’s completely clicked into place.
