  • Evenly apply heat to the edges of the touchscreen to loosen the adhesive. Continue to Step 3 once the edge of the screen is warm to the touch.

  • Do not let the iOpener/heat gun remain on one spot for too long. Excess heat can damage the phone.

  • When reassembling the phone, use the iOpener/heat gun to help the adhesive fuse to the new screen. Heat the screen edges, apply pressure to the screen, and hold the screen in place until it is secure.

As the adhesive loosens, pry up an edge of the screen with a plastic opening tool or an opening pick.  A suction cup may also be useful here. Use an opening pick to hold that edge in place and continue this process around the entire screen, applying more heat as necessary. Avoid damaging the LCD screen connector while prying along the screen edges.  It is located on the left edge of the phone, across from the volume controls.

You may need to remove the mouthpiece and earpiece gauzes from the screen to fit to the replacement screen

Be careful not to damage the adhesive tape on the old screen as you may need to reuse it along with the two gauzes on the replacement screen

which adhesive tape?

What width of adhesive is appropriate to buy to replace the existing one? I can see 1mm, 2mm etc for sale

Avi Silver - Reply

The width of the adhesive tape that goes around the rim is 2mm. But rather than buying generic 2mm tape, which won't seal well at the corners because it would be bent pretty sharply, it's best to get a precut adhesive that is made for this specific phone and that comes with the corners (and everything else) already pre-shaped: it's cut into a phone-shaped sheet, most of which you'll be discarding. Such sheets are available on ebay.

I did not need to use any new adhesive strips to get my screen securely back in place. After placing the screen back, just heat the edges of the phone as before and press tightly (though not too hard, of course) until cooled.

Use a plastic opening tool to flip up the lock on the display cable ZIF connector. Pull the display cable from its socket on the motherboard.
