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.

Resumen del Video
-
Power off your iPhone before beginning disassembly.
-
Remove the two 3.4 mm pentalobe screws on the bottom edge of the iPhone.
-
Use a hairdryer or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.
-
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…. =/
-
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.
-
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.
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.
Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?
