Tools Required

Parts Required

Disassemble the Phone

Remove the two Pentalobe screws at the bottom edge of the iPhone.
Place the phone screen face down on a heating mat.
Set the temperature to 80°C and heat the phone for 2-3 minutes.

Use Phone Opener

The Phone Opener from REFOX is truly an excellent tool for opening mobile devices. Its user-friendly design makes the process straightforward, saving valuable time during repairs. For those who may not have the Phone Opener, a suction cup can serve as an alternative, although it may not provide the same level of effectiveness. However, we highly recommend the Phone Opener for anyone in the repair industry.

Place the iPhone face up on a phone opener. Rotate the knob counter-clockwise to secure the iPhone in place.
To secure the suction cup to the screen, lower the lid of the phone opener and flip down the handle.
Rotate the knob clockwise to lift the suction cup and create a gap between the screen and the frame.
Apply some ethyl alcohol to soften the glue holding the screen in place.
Remove the iPhone from the screen opener.

Open the Phone

Insert an opening pick into the gap under the screen's plastic bezel and slide it along the right edge to separate the adhesive.
Insert the opening pick in the bottom left corner of the iPhone and slide it slowly, avoiding cables.
Place the iPhone on a screen holder and open it by gently swinging the screen up, and leaning it against the holder.

Remove The Screen

Cover the front cameras with protection stickers to prevent damage.
Unscrew the display connector bracket using a suitable screwdriver.
A pair of tweezers will be used to remove the display connector bracket, and a spudger will be used to disconnect the display cable.

Use the tip of a spudger to press the adhesive into place around the entire perimeter of the iPhone.

Final Assembly

Use tweezers to peel off the final release liner and hold the display out of the way while removing the last piece of the release liner.
