Use this guide to remove or replace a faulty logic board in your iPhone 7.
It's important to note that each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.
Opening the iPhone 7 will damage the waterproof seals on the display. If you do not replace the adhesive seals, your phone will function normally, but will no longer be water-resistant.

-
Attach a suction cup to the lower half of the display assembly, just above the home button.
A wide, single strip of packing tape, well placed, will solve this for you. :)
Last comment works well. Thank you !
Using packing tape for a cracked screen should be included in the description in Step 3.
Cracked screen is most probably the reason you are replacing it.
-
Pull up on the suction cup to create a small gap between the display assembly and the rear case.
-
Insert the flat end of a spudger into the gap.
This was SO hard for me to do with the spudger. I couldn’t get a gap to insert it because my phone was so cracked (even though I used tape on the front) to get a solid seal with the suction cup. I ended up taking a VERY thin knife and inserting it straight down to make the initial break that allowed me to insert the spudger.
I’ve given up using a plastic spudger to try to open any of these phones. I use a metal one with a flat base and a very sharp end…close to a razor. As long as I’m careful, it won’t slip and scratch the base. It’s much easier than using these plastic spudgers.

Im trying to get the screen off right now and my phone is not cracked and its still a pain
Using a blow dryer was extremely helpful and using the suction cup towards one of the lower edges was also helpful
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.
-
Slide the spudger to the left along the lower edge of the iPhone.

Twist the spudger to widen the gap between the display and rear case.
-
Slide the spudger up the left side of the iPhone, starting at the lower edge and moving towards the volume control buttons and silent switch.
I recently purchased an iPhone 7. since the last one week I am getting a problem with its battery as it is draining very fast. I have asked Apple iPhone Support and wanted to know about this. But recently I gone through this post and tried to follow the steps which are mentioned. somehow, I am facing the problem with the step 6 as I am unable to slide the Spudger up the left side of the iPhone properly. So may I know some detailed information of this particular step?
-
Insert the flat edge of a spudger into the bottom right corner of the device.
-
Twist the spudger to widen the gap between the display assembly and the rear case.
-
Slide the flat end of the spudger up the right side of the phone to break up the adhesive holding the display in place.
-
Pull up on the suction cup to lift up the display and open the iPhone.
-
Pull up on the small nub on the suction cup to remove it from the front panel.
-
Slide an opening pick along the top edge of the iPhone, between the rear case and front panel, to break up the remaining adhesive holding the screen in place.
-
Pull the display assembly slightly away from the top edge of the phone to disengage the clips holding it to the rear case.
-
Open the iPhone by swinging the display up from the left side, like the back cover of a book.
same dude im such a freak lol omg haha
-
Remove four tri-point Y000 screws securing the lower connector bracket, of the following lengths:
-
Three 1.2 mm screws
-
One 2.4 mm screw
-
Just FYI, if you have an iFixit set with the PH000 you can use that bit to remove the Y000 if you're in a bind.
These screws just spin for me. They don't back out, but the heads aren't stripped either. I've tried applying backpressure to help lift the screws, but no luck
dang im such a freak i messed my i phone device up badly
What driver do I need to remove these screws i’m stuck
i cant use, the Y000 it isnt working.
for me a ph0 worked.
What if I stripped a screw what do I do??
-
Remove the lower connector bracket.
my battery cable connector was stuck to the bottom of this metal bracket plate so be careful when you lift it off
-
Use the point of a spudger to lift the battery connector out of its socket on the logic board.
-
Use a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board.
-
Remove the two 1.3 mm Phillips screws securing the bracket over the front panel sensor assembly connector.
-
Remove the bracket.
Has anyone had trouble getting these two screws off? I’ve been working on these for about 10 minutes and the LEFT screw wont spin. It seems like the little PH000 screwdriver bit won’t even grip it. (The one of the right comes off, no problem)
It looks like I’ll have to pick this project up again with a screwdriver that will actually take off this piece.
I used a #1 flat head tip to loosen.

I had an accident where my iphone has got some damage (cracked screen, metal frame slightly bent).. I can see a lot of iCloud locked devices for sale, some of them for a cheap price. Would replacing the logic board and home button give me a non-damaged working phone? Or what parts would need to be moved for this? Sure I can buy a brand new phone but I like a bit of a challenge :)
the logic board holds the OS, so yes if you were to replace the mother board of the iPhone it should work like a new phone but without touch id
I was trying to replace my screen and while removing the tri-screws it slipped and and scratched the logic board. the black cover is now ripped. will this be okay or is it now damaged and unable to work?
Check to see if there are any metal parts UNDER the black cover that are damaged. If not, you should be ok.
Hi everyone,
i have a problem with my iPhone 7, it’s constantly on bootloop status, I’ve tried to recover with iTunes but it still doesn’t work.
I think the problem can be the motherboard, is it possible? ‘Cause I’m not sure.
I don’t want to buy a new logic board if I’m not sure that’s actually the problem.
I’ve been having that problem with my friend’s iPhone after he got the screen replaced by someone else and now it’s in a bootloop. It didn’t have anything important on it so I restored it after updating over iTunes. It got to the setup screen but after setting up, the phone was horribly laggy and eventually rebooted automatically and went back into the loop. I later read that this is from screwing in the 4 screws holding down the battery connector cover bad and messing up where the longer screw went. I found this to be the case when I unscrewed the screws. Unfortunately the bootloop still stayed even with the screws removed so it looks like my friend is gonna need a new board.
This happened to me. I called Apple tech support. After failing to fix it over the phone, they sent me into an Apple Store for testing. It failed the testing, so they said there was a problem with some of the logic boards in my model of iPhone 7. They then sent my phone in for a free logic board replacement and gave me a loner phone in the meantime. I’ve had my phone for over a year and do not have Apple Care, but they still fixed it a no charge.

Hi,
I’ve got a problem with my iphone7. I just took some videos under the water using my iphone. But later it’s finger id has gone and it’s fully damaged. Now the phone is not working. Is there any option to repair this ….?
Hi Muhammed, sounds like some water got inside your phone. Check out our iPhone liquid damage guide for some basic troubleshooting you can do on your own. When you have the phone open check connectors and pins on the board for any corrosion. If the damage is serious enough that cleaning won’t fix it, you can take your phone to a local repair shop for more extensive repairs.
my iphone 7 got into liquid damage and i stored it in rice box for five days and then start it, but it stuck on boot loop. so then i restore it using itunes then it works fine but after sometime (5 min) , it rebooted and stuck in boot loop (white apple logo). and now it does not boot up . Then what is the problem. Is the logic board is dead or something else. And if board is damaged then how much it coast locally.
hello sir i have a problem i lost my i cloud id and password and i wanna change my whole logic board someone told me to purchase board from (aliexpress.com ) but there is a problem board available but without touch id if i purchase logic board without touch id i know my finger print will not work but my question is that my home button can works if i press to push back menu or not ?plz hlp
Hi, I needed to remove the black adhesive film, which is on the logic board because of a problem with the SIM-Card. Now the adhesive film no longer sticks well to the logic board. Is it a problem? I think the backside of the display construction is pushing it down anyway. If this is not enough, which glue could I use in this case? Thank you so much
will this fix iPhone 7 that is stuck in bootloop after restore fail with error -1 in itunes? i only know the fact that this is related to the motherboard/baseband. can i order just a specific parts either logic board, baseband or hardware?
Where can we buy a 100% guarenteed working logic board for iPhone ?
Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?
