  • 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.

  • During reassembly, new adhesive may need to be applied over the old adhesive to properly secure the screen.

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.

I've extracted the battery and am awaiting a replacement. It holds a charge OK but has bulged to 10mm thick plus some gaseous inflation. This caused the motherboard to bulge in response and popped the screen out of the housing. I suspect that it was, before the "pop" made it obvous, the cause of the failure of the torch/flash. This is because the connection is just by contact pressure between back and motherboard and in the rough centre of the device where the bulge pressure would be most noticeable. So I am hoping for a double cure...

Another discovery: be very careful when re-assembling and remove SD and SIM cards first. They can get caught under the housing and I have broken mine!

Same, forgot to pull out mine and managed to break my 64gb SD-card lol

Muy positivo el artículo. En mi caso no ha salido bien: los tornillos me han dado mucho problema para aflojarlos , incluso dos no he podido, pese a ello conseguí cambiar la batería, pero al estar la cabeza de los tornillo dañados, no he podido volver a montarlo en condiciones. El resultado ha sido que la batería no carga, el altavoz vibra y la pantalla se ha dañado. Me ha parecido que el cambio de batería es innecesariamente complicado, por lo que desaconsejo comprar este tipo de teléfono que no facilita la vida al usuario en una operación tan elemental como cambiar una batería.

Not worth the bother dump the phone and get a make that allows you to change the battery if needed. I have given up on Smart phones, that won’t even make a call in a weak signal area I now use a 15 year old Nokia 7110, new battery cost me £8. and it works where all my smart phones did not. A smart phone is not smart when it can’t even make or receive a call.

Soo, I changed my display and battery and after about 2 months I got ghost touches and I had the feeling that my battery was drained a lot quicker. Now I tried to plug in my charging cable and it turned off and won’t start. It doesn’t get past the booting animation. What could be the problem? Should I try and install my old battery again? It wasn’t broken or anything, just thought I could exchange it after 2 years of use while I’m at it :D
