iPhone 6s Plus Logic Board Replacement

So my screen shattered completely and the screen first had colored lines on tge while right side then it went out completely. If i get an lcd and digitizer replacement I'd that oing to fix it

I would initially recommend a well-lit, comfortable area and placing the screws on a white piece of paper with the screw sizes written down (apparently there are magnetic mats, also). Also, I found placing the phone on a paper towel is good so that if a screw is dropped, it will lessen the likelihood of bouncing away.

I broke my iphone screen in the first step!

This screen removal step got more wrestley than I anticipated. The adhesive is quite strong. I used a flat-ended razor tool that I have to begin the prying - I don’t know how I would have got it started without this.

Ok - just got my battery replacement kit and even got the opening kit for added insurance just in case. Settled down to startwork after carefully cleaning my (immaculate) screen - no scratches or anything, with rubbing alcohol, removing screws and warming with a hair dryer, only to find the suction cup provided in the kit is worse than useless! It won’t stick to the screen well at all. When it does - it pops off at the lightest pull :-( Now what do I do to get this started?!

Hey everyone, if you never have done this part before be aware there is an extremely strong adhesive around the lip of the screen and once again is extremely strong. I had to get a friend to insert the pry/pick into the small gap while I used one hand to brace the phone down and the other to pull the suction cup without it digging into my hand. Go slow, it took me 5 tries because I didn’t realize how strong the adhesive was.

I also had a badly cracked lower screen - that glass was actually threatening to pull off the phone in chunks during this step, even with packing tape. Resorted to @j2arch’s tip and inserted a utility knife vertically into the seam between the display and phone body. Was able to lever the glass enough to get the spudger in there.

I have replaced sevrel screens for my sister in law and my niece. The packing tape has worked every time and that’s with it Shattered and pieces already falling out. You have to make sure the packing tape goes to the edge of the screen but doesn’t touch the frame. I have the plier like screen remover and use that it is much easier to remove the screen by your self with that tool. I also have the little finger suction cup that comes with the kit here. I bought the plier suction cup tool When I had to replace the screen that had the pieces of the screen missing and I don’t regret spending the extra money for that it has made a world of difference. I do this as a hobby it’s not a job for me. The electric divide repair kit from Lowe’s is also a very good kit to help. If you’re only going to do it once the kit that comes with the package is a great deal from ifixit. Well worth the money to spend the little extra to get the kit if you all ready don’t have the tools.

I found it easiest to use two suction cups. One on the front as directed, and a second one on the back. Give the spudger to your assistant, and have them slip it in place while you pull the display from the case.

I gave up with the suction cup as it wasn't working for me with a cracked screen. Having heated the bottom of the phone with a hair dryer with a high heat for a good minute or so, I used a safety scraper (essentially a razor blade in a holder) along the bottom of the phone to separate the screen from the body of the phone. I used the scraper vertically between the bottom of the screen and the phone body and levered it sufficiently so that I could fit the spudger between the screen and the phone body. My experience when I first used the spudger around the frame was that the cracks in the screen caused the screen glass to separate from the frame, so I had to re-do it and ensure that the screen frame was separated from the phone body.

I also struggled with this step. Lots of heat, 3 different suction cups, I finally could see a small gap... much too thin to fit even a piece of paper into. A video on another site said it was the easy way. I used a sharp craft knife barely into the seam between metal and glass and pried slightly. And it started up. Still a pain freeing the rest of the adhesive. Perhaps the adhesive really sets up over the course of 5 years? I have it hinged open now, so onto the next steps.

For this part, neither PH000 or Y000 worked. Technically, it’ll set you back 31$ because you will need the PH00 screwdriver for this part, and the part where you need to open the screen. They have ph00 screwdrivers in every hardware store and even ifixit.com. just know that they put the wrong screwheads for you

Do not lose track of which hole these screws go into. They MUST be put back into the correct hole that they came out of. If not, you will get the dreaded “long screw damage” on the mainboard, and that will be the end of the show.

Just remember where these screws go, and it will be fine.

Ended up employing a Philips #0 from a regular jeweler/precision kit on the 2.3mm screw. Bits seem a bit off for this step.

Which screwdriver from the kit do I use for which screw?

I made a mistake and unscrewed the screw just north north west of the one circled in yellow. Of course I lost the screw. Can anyone give me any guidance about this? what does the wire connected to it do? What is the size of the screw, in case I have to replace it?

P.S. This is another reason to consider the possibility of NOT removing the screen just to replace the battery: removing the screen presents a additional possible headache, especially for people like me with bad eyesight who probably shouldn’t be doing this in the first place.

Use dixie cups and label them for each part you take out. You can stack the dixie cups to keep them in order.

I skipped this for the battery removal, but when I went to replace the seal, I had to remove it anyway.

I lost the bottom left screw of the five in this step - anyone know if it’sgoing to cause a problem? ‘m going to go ahead and put thephone back together anyway - wil report back withresult

OMG…. SO excited! It works! Seems that missing screw wasn’t an issue. The reason I’m so excited is, I’m a senior and have bever attempted anything like this before and was worried I’d mess it up, or it just wouuldn’t work for whatever reason. I know I never would have tried if it weren’t for finding this site, the great service, parts to do it and the videos/guides. Thank you so much ifixit. :-)

I changed the battery, without removing the screen, when I closed the phone the front camera and speaker no longer work.

I don’t recommend using the spudger for this as you can do more damage that way. I scratched the black square thing underneath.

I managed to remove the battery without disconnecting and removing the display first. This avoids possible difficulties in these steps (see below).

One has to be careful that, while fighting with the battery strips, the display remains in its 90º position

This part was a very frustrating experience for me.  I thought that my replacement screen was just poor quality, as it worked when it wanted to work.  Pressing home/power repeatedly sometimes brought it back, charging to 100% also brought it back.    The actual problem was that it is very easy to get some of the gasket material caught in the connector, which I couldn’t see until I used my jeweler's loupe.  I used 91% alcohol to carefully clean all of this off until all pins were shiny, and it took about 6 tries to get it right.  However, the screen’s been running well for 2 days now.  I already bought another screen replacement which I have for a spare as it was 100% not the problem.

I followed all the steps, so the sound is missed. What could be happened? thanks a lot. Fabio Balbino

Always make sure to disconnect the battery before you do any work on the phone replacing any parts the digitizer or anything. And before you start make sure the phone is turned off you don’t want any power surges. If you also have a static electricity bracelet that also is a plus to use but isn’t a necessity just a nice piece of mind. Some cases you do need to use one so you don’t discharge static electricity to an electrical component and mess it up.

Be very careful in this step. I noticed it’s very easy to tear the flex when trying to lift it out of its socket from the right side.

What is the cable and how is it connected/fixed to the motherboard between the bottom socket and the screw hole.

Mine came loose somehow?

I figured out my own question its the Wi-Fi diversity antenna cable. But how is it connected/secured to the motherboard?

The 6s plus screen repair kit i bought has the wrong size cable here on the replacement part. SOL.

Once I accidentally disconnected the display assembly cables before disconnecting the battery. Now the home button and fingerprint sensor doesn’t work. Any solution to this?? I have tried a different home button, even that doesn’t work.

I changed the battery on my iPhone and put all together again and charged it. When I pressed the home button the lock screen with my picture appeared and when I pressed it again the screen with the digits from 0 to 9 appeared. I was asked to enter my passcode, but when I did that nothing happened, the phone did not open.

What could be wrong? Is the home screen cable not fully connected or what could be the reason for this?

These instructions worked great for me. Thank you!

My phone doesn't have a cable running here
