How to Replace your iPhone 3G/3GS Glass, Digitizer, and/or LCD

After about 3 years of dropping my iPhone 3G on various occasions, a drop onto the tile floor at Atomic HQ did her in:

I made a trip to the Apple store to talk to one of those certified Genius dudes. Pretty impressive Apple can draw people with such amazingly high IQs to sell their products?!?

Anyways, my genius was actually very helpful, although I found out that to have them fix it, I would have to pay $100, and they would basically replace the entire front assembly (glass, touchscreen, LCD, button, speaker). My other option was to go ahead and take advantage of my upgrade to an iPhone 4, though I know that the iPhone 5 is due out this Fall, and even the Genius was honest enough to point out that it would be best if I could wait. So I started looking for DIY options…

I found the glass and touchscreen together for $2.00 through Amazon! I ordered it, along with a toolkit that gives you the 3 necessary tools to go the surgery for another $1.60. Later I learned that the the glass/touchscreen kit I ordered came with the tools as well, though I wasn’t too saddened that I spent an extra $1.60. I was also told, to my surprise, that according to Apple store policy, I could bring any failed DIY attempts to the store and they would still fix it. Therefore, I decided to take the plunge and try to fix it myself.

I found the video below, which is actually pretty well done, though the guy in the video has done this before, and makes it look a little too easy. Basically, you do the following:

  1. Shut phone off (Duh?!?)
  2. Take the SIM card out (that gives you your phone number and service from your provider)
  3. Take 2 screws out (don’t lose them!)
  4. Use the suction cup provided in the tool kit to pull the glass/lcd assembly out of the phone (be gentle, and watch the video!)
  5. Disconnect the 3 small (delicate) cables
  6. Remove the LCD from the assembly by taking out 6 more screws (keep these separate from the others, due to differing size)
  7. Use a hair dryer or heat gun to soften the adhesive that hold the glass to its frame (on LOW!! more later…)
  8. Clean off the broken bits and pieces of old glass
  9. Use the adhesive sticker provided to attach the new glass
  10. Put it all back together
  11. Done!

  • BE PATIENT AND GENTLE!! (my biggest problem)
  • If you are skeptical of your abilities to do the glass replacement, spend the few extra bucks to get the entire cover assembly (below)
  • I failed step 7 by getting too impatient that the adhesive wasn’t getting soft enough, and I used a heat gun for too long, which ended up resulting in melting the little dimple under the home button that rendered it nearly inoperable.
  • I must have not reattached the cable to the LCD fully, and I ended up frying it!!! I had to order a replacement LCD for another $23 (and a new home button assembly for $0.60)
  • If you’re an idiot like me and fry your LCD, the LCD kit you will receive will have a new LCD frame and the LCD itself which comes with an adhesive sticker to attach to the frame.
  • The LCD, if you are replacing it, is very fragile. I was pressing down on it to make sure it was secured to the frame, and I cracked by brand new LCD! In the end, it still works fine, but has a tiny wrinkle in the image which has mostly disappeared (whew!)
All in all, I was surprised how easy the process was, though I would have been a bit more careful in order to avoid the second round of repairs. I especially had fun digging into the guts of the iPhone to see how they jam all that good stuff in there to make it work. If you feel up to the challenge, best of luck! Just BE PATIENT!

    I enjoy the “Notes for Dummies” so much! Sometimes our best lessons come from our dumb mistakes. I bet you’ll never repeat most of these mistakes… except for that annoying “Be Patient” part. Patience is probably the biggest lesson many of us have to learn over and over. So simple, yet so challenging.

    Hah! Now do you want to try it on my iPhone 4? ;-) i’ve been using it with a cracked screen for 2 months. It still works perfectly so I can’t justify paying the $100 at the apple store, but it definitely isn’t as pretty as it once was.

    Patience is often learned after stupidity. In a hurry to fix the keyboard on a laptop, I used a heat gun, not realizing how hot those things are. Fried the keyboard which made it uneconomic to fix it because it was an old machine. Cost = new laptop for one moment of dumb.

    • escher7,

      Yes, that is definitely the case. When I had to replace my LCD on my iPhone, it has a plastic frame that you attach the LCD to with the adhesive backing of the LCD. I put it in the frame, and pressed down on it to ensure it was attached securely. The LCD, being delicate, ended up cracking right down the middle :(

      Probably partially due to my lack of patience…

      Thanks for sharing!

    Hey there!
    I ordered the 3G kit from Amazon but when I hold the new screen up to my iphone it looks like it is going to be too small. Is that normal? I’m afraid to open everything up if the screen isn’t going to match. Any advice is appreciated! Thanks!
