Heat an iOpener and apply it to the left edge of the phone for two minutes.
You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.
As you wait, take note of the the following areas:
Display cable—be careful not to slice too deeply near the edge here, or you may damage the display cable.
Fingerprint sensor cable—be careful not to slice too deeply near the edge here, or you may damage the fingerprint sensor cable.
Swing open the screen and prop it up with a small box as you work on disconnecting the flex cables.
During reassembly, this is a good time to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.
Using a pair of tweezers disconnect the vibrating motors connector near the bottom of the device.
Caution: these wires are very delicate!
Also note that while it may not look the same, this connector also lifts up, similar to the camera and battery connectors, and does not slide out.
Alternatively, you can also leave the connector plugged in and simply remove the vibration motor from the frame and keep it together with the motherboard as you remove it, being careful to not dangle it from the small wires.
