iPhone 7 Logic Board austauschen

From personal experience, I highly recommend before doing this procedure or any other, that you do a backup of your phone (preferably local) in case your procedure goes south.

Before starting, I would recommend backing up your Iphone’s data just in case.

If you managed to make it to this section, just send the phone into apple for 50 + 6 dollars shipping. The ribbon cables on the screen are designed to break. I can literally twist on the rest of the cable and it won’t fall apart but there is a diagonal section where it snaps. This is the fault of apple and the fault of ifixit for misrepresenting the fragility of the cables.

Had to reheat it a few times for a minute each with a hairdryer to get the seal to break after pulling and rocking the suction

I’m technically challenged. Is there a premier national service who can professionally install a replacement battery got my 7 +?

Do the screws come out in total?

Is it the P2 you should use for the bottom??

I heated the bottom of the phone with a hairdryer and then used a syringe to put a couple of drops of acetone directly into the bottom two screw holes. I GENTLY pulled on the screen with the suction cup and used the pry tool to GENTLY separate the screen. The sealant is applied around the entire display so be very careful pulling it off so you don’t break the fragile display cables.

At first it was very difficult to open, per instructions. I used a heat/ice pack and nuked it for 1 minute. The pry tool wasn’t working so I carefully used my pocket knife to wedge the cover open. The rest of the procedure went well until I cracked the glass while trying to get the top right corner to pop off. Other than that mistake, all went well. Tip: before setting the new battery, attach the battery connector first and leave enough room for the taptic engine, or better yet, place the taptic engine before adhering the replacement battery. This way you’ll have a small gap between the two, whereas mine barely fit. Good job on hosting the video, Gwendyl.

I love the fact that the screw bit and shaft are magnetic! I almost lost a screw and found it attached to the magnet.

This way you’ll have a small gap between the two, whereas mine barely fit because I placed it almost too low.

Good job on hosting the video, Gwendyl.

I totally Mr. Myagi’ed it, by rubbing my hands together until they burned, then held the phone un my hot hands. I did this 5-6 times over a couple of minutes. It was a good zen way to get started!

Can I use a cpb heating pad to soften the adhesive ? If yes how much time and temperature ?

Will doing this compromise the screen protector (Zagg) that I have on my phone?

Hairdryer worked for me but I needed to use a razor to pry it open at the bottom then used the spudger

Thanks for this, the other instructions make it seem SOOOOO simple to open up the case with the suction cup! It actually is hellish. The instruction here about the pre-heating and the required patience really helped!

I found this to be completely useless. It didn’t help at all. I had to use a heat gun instead. Waste of money.

I’ll experiment with leaving the phone in the sun until the Temperature Warning comes up so the phone tells me when it’s too hot to be safe.

Maybe it will be hot enough, maybe it won’t—

I use a rice pack in the microwave. White dry rice in a sock sown or tied, then microwave (1 minute +/-). The dry rice heats and retains heat for a long time. My kids loved them in in bed during cold winter nights.

I have changed now Iphone 5 Battery, IPhone 7 front camera & another iPhone 7 rear camera. The instructions along with the comments are really important. Be patient & read them several times. By using your heated gel pack 3-4 times for 2 mins or so on the bottom end near the touch button you will be able to pry with your razor & then you can use your spudger. Thanks for this great guide.

I would DEFINITELY recommend to NOT use direct heat (hair drier, etc.) on the phone. I used a hair drier to help heat the phone and ended up damaging the home button (would not work after the replacement and I did not touch or take apart the home button). Note that a damaged home button cannot be replaced so I will end up using the alternative “screen” home button going forward with my phone. Instead I would recommend preheating something else (example - metal / coins / ceramic / beads / glass stones / cookware / etc..) to a warm-to hot (but not burning hot) touch and place the heated items on the IPHONE (or visa versa) to heat and soften the adhesive.

I used 1-gallon Ziploc back and poured 1qt of boiling water into it. I placed my iPhone on a corkboard and the bag on top for 120 sec.

It worked like magic. I just pooled the screen with the suction cup, and it got loose from the case. No heat damage. Everything works.

I placed the iOpener heat bag over the bottom of the phone, disregarding the home button. Now it doesn’t work. All subsequent procedures went well as I was very careful. I should have read all the posts! Protect the home button from direct heat. Fortunately, now using the Assistive Touch feature is better than buying a new phone or replacing the home button.

It’s better to choose an iPhone back case to cover and protect your phone from bumps and scratches. Choosing premium cases is the best option for long-term safety. If you need ***iPhone 7 phone cases*** then you can check them out!

I agree that using packing tape for a cracked screen should be included in this steps description. I don’t have wide but turned mine horizontal and that worked great.

Bekomme die Oberschale einfach nicht runter! Trotz mehrmaligem erwärmen durch den iOpener und seitlichen bewegen! Weiß nicht mehr weiter!

Wouldn’t that screw up the Touch ID?

I am not getting this open at all! Why an I provided with tools that can't help me ??‍♀️

I couldn’t get the bottom to lift first, but the left side did, so I started there and worked my way around the horn.

Hold the suction cup provided in almost boiling water with tongs for about 30 seconds, then it will actually work :-)

This is not working for me. How long does the heat need to be applied? Still trying right now…. =/

Apply hair dryer for at least 1 minute. I inserted the tip end of a thin mini screwdriver and with some force, pryed it open and inserted my plastic spudger to continue the separation process. It worked, just be patient.

Please wear protective glasses! My iPhone glass was severely cracked, when separating the glass a corner area of broken glass exploded in my face. Apply transparent tape over the broken glass to contain the shards.

I second Jessica’s January 8 comment.  I just finished a battery replacement on my iPhone 7 and this step was the most nerve-wracking part.  I ended up using a sharper (but not razor-sharp) metal object to get this done with confidence (tried the spudger and guitar pick but not thin enough).  The tool I used was the exact duplicate of what iFixIt calls “iSesamo Opening Tool” in their tool selection.  I did the heat up with a hair dryer (after attempts with an iOpener hot pad) and the secret (as Jessica also noted)  was to not use the angle of attack shown in the pictures, but to push it in more vertically along the bottom edge while pulling up on the suction cup.  From there you can easily lever the tool to the lower angle-of-attack (as shown in the picture).  I actually used the metal tool for most of the perimeter as well, just don’t go deep (you don’t need to).  Notes: my display was intact, and I was able to pull up fairly hard with a glass screen protector still on it.

This is frustrating. I heated the lower edge with a hair dryer for 1 min on high about 3-4 times. In between each heat cycle, I rocked the suction cup back and forth. I was eventually able to create significant space for the provided tool. This takes a lot of patience. Once the space was created, it was very easy to remove the screen.

use a fingernail, then the blue tool, then the spudger

The iOpener worked just fine for me. Had to keep it on for a few minutes. I also was able to get the suction cup seal right close to the edge, over top of the home button for added leverage. Used the blue tool and transitioned to the spudger. Slow, steady pressure…and patience. ;)

Just a question. After this operation the impermeability function was compromitted?

The trick I found, was to add packing tape right across the bottom over the home button then use hairdryer on the end, then suction cup on the very bottom and it lifted enough to get a gap. No one mentioned how it would be impossible to handle the phone after the hairdryer ;)

Didn’t have an iOpener and 60 seconds on a hairdryer wasn’t doing it for me. Still wouldn’t budge. I had to take a very sharp razor along the seam at the bottom between the speakers. It took about 20 passes for it to separate enough to get the spudger in. Make sure you keep the razor at a 90-45˚ angle and that it goes no more than 1-2mm into the phone. The bottom of the phone is metal, but the casing for the screen is plastic. So if you cut lower than a 45˚ (flat with the phone) you risk cutting into the casing. Apply light pressure when making the passes. I would just do the razor on the flat part on the bottom.

I used a hair drier while lifting up at the same time until I could get the too inside. The seal is pretty finicky. Just take your time and you should be fine. Work the hair drier and the tool all the way around before lifting the screen up and off. There will likely be sealant stuck between the screen and phone. You can just break it with the tool.

This step was impossible for me despite using a blow dryer and having no cracks on the screen. I finally took it to a local repair place and had them do battery replacements for two iPhone 7’s. The girl let me watch her do it. She used a razor blade (just until she had a small opening that she could hold open with her fingernail) and confirmed that she too would have difficulty opening it with a plastic tool and suction cup. The plastic tool was great for prying the rest of it open once a crack was there, but she said she would never try to use that as the tool to initially open it. The tools provided for initially prying open the screen are inadequate.

Hopeless - no chance to get the screen off without any damage. No matter what tools, heat etc.

I second what others have said, definitely use a razor blade to break the seal! Heat helps some, but too much direct heat is bad for the screen. Would have been impossible if I hadn’t read the comments, thanks everybody!

Use extreme caution on this step. I was just replacing my battery and now i’m buying a new screen. The screen was very stuck, I pulled to hard and it popped off suddenly, completely destroying the screen.

When the right heat is reached, the easiest way is to use a metal iFlex to create the initial gap, then insert the Jimmy or iSesamo next to it so the gap gets bigger, at this point you can get in with the flat edge of a plastic spudger and slowly slide it in the borders to cut the adhesive. You will still need to force a bit the upper end to separate the screen by pulling it down while keeping up the screen, and twist to the right. I hope this is clear enough. Never apply too much strength too quickly anyway.

I used the short blade of my swiss knife to make an initial opening. Using the sharp edge, inserting about 1 mm straight down and twisting down into a 45° angle. Then I was able to insert the spudger.

It was a really excruciating process of heating, lifting with the suction cup, trying to slide in the spudger/pick, and repeating the process for 20 times or so. But in the end, my patience paid off!

I used a hair dryer, then used a safety razor blade parallel to the bottom edge to push straight down (from the glass side, towards the back) while lifting with the suction cup. I wiggled the blade (top to bottom) while pressing down gently, until I saw a gap that would accept the spudger. It did not take much force on the blade or much wiggling, just patience.

Followed Gene’s approach with heat and a razor blade. I was nervous, but went slow; it was very easy and effective. Great tip. Just be patient and don’t rush yourself.

I would skip right to using a single edge razor blade and a hair dryer to create the gap needed for the spudger.

Think plunging the toilet - it did not work for me for a long time. the suction cup would not stay held on a long pull. I found that tiny push-pull repeated motions, reseating the suction cup with each push slowly overcame the adhesive, and contributed heat :). I had it after about 50-70 cycles

seconding this comment from Ted ~~~ “the secret (as Jessica also noted)  was to not use the angle of attack shown in the pictures, but to push it in more vertically along the bottom edge while pulling up on the suction cup.  From there you can easily lever the tool to the lower angle-of-attack (as shown in the picture).”

I echo what everyone is saying here, the spudger just isn’t good enough for this and neither is a pick. The razor is the best way to go. I tried using a very sharp penknife blade and managed to damage my LCD (somehow!) and the bezel so I ended up having to buy a new screen display as well as a new battery. Think twice before doing this. Be prepared to shell out for a new screen just in case it goes wrong. You’ll also need the heat gun (the iopener was useless). If you do need to buy a new screen, make your life easier and get one with the speaker, forward-facing camera, home button, etc., already attached (you can then replace the home button) or you’ll end up having to transfer all these from your old display.

I finally got the screen up but shattered it in the process. I was replacing it anyway but if the screen is not what you’re replacing, take EXTEME caution. The suction cup and spudger were not working for me to get it started. Thanks to the comments, I used a razor blade and a heating pad and went back and forth, back and forth, between heat and pressure from the blade. Once you get a gap, the spudger works great and the screen comes up easy.

The suction cups that iFixit sells are crap. They don’t stick at all. Glass on the phone is pristine.

More feedback on this “guide”:

“Pull up on the suction cup.” What does this mean? If I just pull up on the suction cup (with a real one that actually sticks) it just lifts the phone off the table. You need a description of what you are pulling against. Do I try to hold the frame of the phone? Do I try to stick something in the lightning port to pull against? Do I try and get something against the edge of the rounded metal on the edge of the phone (this usually just slips off). What am I pulling against???

I found a combination of iOpener, suction cup and razor blade, all applied at the same time, worked for me and I didn't need to use a hairdryer.

Dumbly, I thought that with the Spudger I'd had to hold the phone from the charging hole while pulling the screen. .. In the end I inserted the two ends of the tweezers(bends the tweezers and may damage it) in the screwdriver holes and pushed the screen out upwards so that I could insert the sharp side of a knife.

This was my first iPhone battery replacement and I can say this was the hardest part.

Be wise, go for a hair dryer and heat up the phone bottom (long enough). iOpener did not work at all for me. Heat up, use the suction cup and push the opening pick under the frame as soon as you see movement along the frame.

Then use the spudger to wander around the whole frame (leaving the pick where it is). Done!

True about sputter i cracked my screen trying to lift it up while using this device back in 2021

One little corner at a time. Don't try to do the whole bottom at once. I heated with a hair dryer. Applied the suction cup to one side and worked the corner till it started to give. Took a minute or two. Use a magnifying glass to help see when it's starting to come loose. It's not hard to do.

I agree, these guides are half imaginary idealism it seems. A thin metal edge pushed vertically down just a fraction of a mm will cause the adhesive to weaken better than any amount of heat, but affects the final appearance sadly.

I just broke cable connecting camera and earpiece speaker to logic board. Be careful with it.

This section is missing a critical step - to lay some Post-It notes or something below the right half of the phone when you swing it open, so the ribbon cables don’t get sliced by the sharp edge of the phone case. I broke the Home Button ribbon cable because there was no strain relief when I laid it open.

I also broke the home button cable and now I have to use assistive touch.

Keep the suction cup on the display to keep it propped up while you disconnect the ribbon cables.

I broke the short ribbon cable that attaches underneath the lower connector bracket. Be SURE when you lift the display, you do it from left to right. I thought I had the phone oriented correctly in my hand, but I was mistaken.

Put the suction cup on the right side of the middle of the screen when you rotate it up and out. It serves as a nice stand to take the pressure off the connectors.

no mention of what you do once u open the book. are the ribbons long enough to lie flat  or do we have to keep screen raised while removing screws,, like when we hold screen up 45 degrees while removing 5 screw plat when at top of phone. I only realised how fragile the ribbons are and how important it is to use suction  cup to rest screen on an angle so ribbons don't stretch or cut on frame.

thanks for the above comments and probably the most important section. I just hope I closed t before I fdid any damage. its lke the fragility of iPhone 3’s all over again.

I just broke one of the cables… yeah, it is not nice… I’m lucky in the sense the screen is still working, but the button is not.

Trying a cheap screen on Ebay (that contains the cable) do 20$, after that, it’s a new cellphone…

Be EXTREMELY careful when you lift up the screen. I broke 3D touch cable, and the home button stopped working. Had to replace the whole display.

Attention ! J’ai cassé la nappe de la caméra avant !

What driver do I need to remove these screws i’m stuck

i cant use, the Y000 it isnt working.

What if I stripped a screw what do I do??

Yep, only the 2.4mm came out, other 3 won’t budge, and worried I’ve stripped the heads. Anyone got any ideas?

It’s the screwdriver bit that is the problem. I had the same issue with 2 Y000 bits not grabbing the screw properly. I fixed it by using a small 3 sided file to slightly grind the groves in the Y000 bit just a bit deeper. Then the bit worked like a charm on these screws.

Use Y000 on all 4. U have to be very sensitive on the 1.2mm screws. Put the bit in the screw, put the left pointing finger on top of the screwdriver and turn the driver carefully to the right until you feel a “bump”, thats the trick :-), then you are able to screw the screw out.

For me the key here was a LOT of downward pressure to ensure the Y000 bit caught in the screw. Not sure i can describe how much exactly, but is was significant. Otherwise the bit would not catch.

What do I do if I Stripped one of them?

Can’t get them removed what to do ?

The first, longer screw came out fine, but the other three wouldn’t budge, regardless of more/less pressure or a slight angle or anything. I finally filed down the tip of the Y000 bit ever so slightly, and then it worked. Hope this helps someone.

Filing down the bit worked for me. The tip about putting an index finger on the end of the screwdriver handles and then turning gently until it clicks into place was very helpful! Using these 2 tips I didn't need much downward pressure. Screws are out in a few turns.

If you can’t get the bit to grip the screw properly, you can use a little bit of the water-proof sealing between the bit and the screw. That worked for me. Hope this helps anyone.

Mine came out easily. I placed the screws in the area where the bit goes in my kit so I can keep track.

I used a bunch of medicine cups to track my screws. You need like 12 if you want them all in cups. I ran out. There are so many different sizes that literally vary by 1mm. The tolerances on these things are tight.

I use a 28 day pill box and keep every screw separate and reburn to exact slot because they all vary in length, width and can really damage u phone if too long and nt secure if to small.  use a magnetised screwdriver,  or make the cheap freebees magnetic for a short period by rubbing it up an a magnet. lol

Absolutely ridiculous had to go get a different one just stupid

I couldn’t get the lowest one out and just turned the metal bracket out of the way and replaced battery.

Was able to get the outer bracket screws out using fine needle nose pliers 90 degrees straight down for the outer ones by pressing down a little and using medium gripping force. Had to take these out first before i could use tweezers on the middle one, for which I had to use tweezers to hold the screw, then rotating the bracket (not the screw) counter clockwise a few mm many times over to slowly unscrew it 1/32th of a turn at a time, repeat. (this loosened middle screw). Think ‘rotating bracket 3minutes/degrees counterclockwise at a time while holding screw in place.) You are gonna need really small/fine pliers and tweezers for this because the heads are countersunk into the bracket.

The top screw in the step was much longer than 1.2mm. It has the same head as the 1.2mm, but different than the 2.4mm. It’s good to keep track of where they came from.

All are so small that I thought I’d lost one, when it was still sitting in the phone.

To help tell if the screw is turning, put a small dot from a marker on the head of the screws.  This helped me to know I wasn't just stripping the head.

try heating the iPhone with a hairdryer or a bag of rice or about 60 degrees in an oven for 3 minutes . It has worked for me. If the screws don’t come out while hot the will come out as the iPhone cools.

Thanks, Josh Martin! Mine was stuck too, so I lifted carefully.

Reconnecting the battery connector was a bit difficult in my case. The cable that comes out of the battery was a tiny bit too long, or that I placed the battery a bit too high (i.e., too close to the top of the phone). It took me several frustrating minutes of fiddling with the connector for it to sit right into the socket. I was not sure if that was connected correctly but, alas, the phone came back to life when it was turned back on.

VERY IMPORTANT NOTE: Please READ the reply here by jason.

It is very easy to knock off or nudge the little pins near the battery socket, see https://guide-images.cdn.ifixit.com/igi/... and https://guide-images.cdn.ifixit.com/igi/....

Those pins are the data lines to extract battery info: temperature, charge, etc. If you accidentally nudge/knock off them the phone could appear to work normally, even for a few days. But then you will start getting wrong battery reads and then after that it may suffer a reboot loop. If you enter settings > privacy > analytics & improvements and you scroll down you will find panic errors from thermalmonitord that there are missing sensors (TG0B or TGXXX) and you will have to micro solder them. DO NOT NUDGE THEM and double check the socket connector when reconnecting the battery.

An earlier comment said to re-apply the suction cup to the right side of the display so that it acts as a stand when the phone is partially opened. That’s a great idea, and helps a lot for this step and the next.

Hey – I broke one of these flex cables and I cant find them to purchase anywhere. Can somebody help me? It’s the LCD connector first and what is the second flex cable for? Thanks!

I replaced the screen and have ended up with a blank screen. Touch control seem to work (touch button works and I can shut down the phone by pressing power button for some seconds and then swipe left to right in the upper part of the screen). But the screen is blank. I’ve tried to disconnect and connect the two connectors in step 16 but with the same result (blank screen). What do I need to do?

Thanks for advice!

this point is the most important in the whole manual.

Please pay attention not to strain the flex cables or they will end up breaking

I should have been more careful - the second cable tore off.

My own fault after having done this replacement about four times previously without any issues, I clearly got cocky and didn’t pay enough attention.

Be VERY CAREFUL and remember to unplug those cables. Don’t skip steps.

I’ve now had to order a replacement screen.

Echo minimalist’s comment here. Prop the display up and skip to step 19 to save time and remove risk.

If you replace the screen and there is no display apply io propyl alcohol 99.9 & purse to both connectors on the screen and on the iPhone with a clean toothbrush and let them dry for 45 minutes and then fit the screen and reassemble the iPhone..

It works for me . when I get a new screen I do t5his before fitting it.

Can somebody help me with the name of the part that these cables belong to? The bottom one got ripped during my battery replacement, I need a new one but unsure what to look for.

I couldn’t get the two screws out either—used the correct screw tip and everything. Stripped the screw. Will now attempt to just keep the cable attached…..

the two screw i have are stripped and i have n way of getting either screws off whats my next bet

I think part of the issue with the iFixit PH000 is that it is slightly too pointy. The PH00 fits better because the splines engage the slots of the screw before the point bottoms out. The PH000 tip bottoms out in the screw’s center point and the splines don’t engage as well. I have other PH000 tips that are more blunt nose and they work better than the iFixit bit.

Use the J00 bit. Worked perfectly

PH000 screwdriver didn’t work for any of these screws, or the barometric vent, or the taptic engine. It was too big. I had to use a different screwdriver from another kit I had.

I’d do this step before removing the ribbon cables by the battery connector. That way you can disconnect all of them at the same time.

i used the little +-shape 30 mm screwdriver (not the Y…but the + shape).

the cable tore. is that it i need a new phone?

You don’t need a new phone, but your selfie camera and phone speaker will not work. You can get replacements for that about $10.

Reconnecting this cable and coverplate took a good 20 minutes. O_O

What can I do to remove the screw (I stripped it)

I also had issues to loosen up the screws, in two parts the right side up and the left side down, i think the PH000 is to pointy or something or its too hard for the srews of the iphone, i cannot take it off and know im regreting i bought i order all the way from Paraguay in south america and know so angry it doesnt work

I skipped this step. Just be really careful not to pull on the screen.

The guide says they changed these to the Y000 “at some point in the t middle of the product’s lifecycle”…

That can’t be true, I have a *day one*, preordered iPhone 7, and mine had, unmistakably, Y000 screws!

and also, I’m just faithfully following the guide here, but can anyone clarify *why* is is necessary to entirely remove the display AND the Taptic Engine at all? The battery seems accessible just fine… oh well

PS- I’m doing this on an older backup iPhone 7. My iPhone 12 Pro just went berserk and stopped working completely a little over a year after I got it day one of its release… since the iPhone X I’ve only had easily breakable, overly sensitive phones. I’ve had every numbered iPhone except for the 8 (I got the X released at the same date) and the 11, and man, are these newer iPhones post X fragile!

After putting together, I had a continuous loop boot up (as noted above). I saw articles where this (front panel sensor connection) was the reason. I disconnected this connection and the boot up loop stopped. I tried reconnecting several times but had the same problem (boot up loop). However, it turns out that I needed to apply extra pressure when installing until a heard a (faint) second click when pressing down. Note - before I was using the spudger to press the connection together, which didn’t do the job. I ended up using my finger to press harder to get it to click in. Solved that issue.

The ribbon cable on this step is torn. Is this something that can be replaced? Is this only to the earpiece?

The ribbon cable on this step is torn. Is this something that can be replaced? Is this only to the earpiece?

The screws are not threading in for some reason. I measured the screws to be exactly 1.2mm with a caliper.

I received two boxes - one box contained the repair part, the other was the tool kit. I only opened the tool kit before disassembling the phone. The standoff screwdriver bit was not in there. Neither was the guitar pick. I used a real guitar pick and a small standard screwdriver from my toolbox. When I was ready to reassemble, I opened the repair part box and guess what was in there - the standoff screwdriver bit and guitar pick. So, I guess if you just order the part it will come with (at least) those two tools. The tool kit contains tweezers, suction cup, three screwdriver bits (tri-point, pentalobe, and phillips) and screwdriver handle, a long black spudger with a flat end and a pointy end, and a smaller, thicker spudger with a wide, flat ends.

The flat end of the spudger works a treat too.

Thank you, bronyar. Since there is a box labeled “Repair Tools”, I never would have looked in the parts box for tools. I was able to use the standoff tool to takie the phone apart, not just to put it back together.

I used standoff bit for iPhone from my pro tool kit

I broke mine while doing this step. A bit confusing. You’re just supposed to bend it out the way, not pull on it entirely. Will the phone still work without this?

$@$*, i broke the grounding bracket

I just didnt bend this one.. Ill tell you how it went
