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.

Video Overview

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.4 mm pentalobe screws on the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

    Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?

    Cooper Chase - Reply

    Confirmed, the screws have a black ring seal around the head.

  2. Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • 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.

    It is a process. I heated the lower area of the phone with a hair dryer on and off (1min each) about 3-4 times before I was able to get the provided tool in.

    Dan - Reply

    I suggest using a hairdryer. I used the iOpener for maybe 30 mins to no avail. However, when I used the hairdryer the screen came of much quicker.

    • Attach a suction cup to the lower half of the display assembly, just above the home button.

      • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

    The glass is completely cracked and the suction cup doesn't work because it gets air in between. any tip?

    Display is glued and doesn't come off.

    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.

      • The watertight adhesive holding the display in place is very strong, and creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, rock the screen up and down to weaken the adhesive until you can fit a spudger inside.

    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

    Jordon Johnson - Reply

    Using a blow dryer was extremely helpful and using the suction cup towards one of the lower edges was also helpful

    Jordon Johnson - Reply

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

    Chris Gallego - Reply

    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.

    Ted - Reply

    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.

    Dan - Reply

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

    Therese Peffer - Reply

    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. ;)

    • 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.

    Add Comment

    • 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.

    • Do not pry along the top edge of the phone, you risk damaging the plastic clips securing the display.

    Add Comment

    • 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.

    Add Comment

    • Pull up on the suction cup to lift up the display and open the iPhone.

    • Do not raise the display more than 10º as there are ribbon cables along the right edge of the device connecting the display to the logic board.

    do not pull up pull sideways it will brake

    • 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.

    • Be careful not to damage the plastic clips on the top edge of the phone.

    Add Comment

    • 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.

      • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    I just broke the cable to the battery!

    I just replaced my screen and worked out that these are actually a wee pocket that slips over the pentalobe screw holes on the replacement screen. I’m not sure if it’s an additional water resisting mechanism or if it’s to add additional traction for the screws

    • 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

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    Ahhh shoot! accidentally ordered tri-wing vs tri-point (must have just looked for y000).. It seems they only did this to annoy repair folks because not everything is tri-point on the phone...

    Steve - Reply

    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

    Jeff Hurst - Reply

    The Y000 took out one of the screws but not the other 3. I even tried the PH000 as suggested but nothing.

    • 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

    Josh Martin - Reply

    This may have been intentionally done by Apple to make sure the battery gets disconnected before any other connector is disconnected. So always make sure to disconnect the battery before disconnecting and reconnecting the connectors for the display.

    • Use the point of a spudger to lift the battery connector out of its socket on the logic board.

    • Bend the connector cable up slightly to prevent it from making contact with the socket and providing power to the phone.

    • Make sure the battery is disconnected before you disconnect or reconnect the cables in this step.

    • 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.

    • To reconnect these cables, press down on one end until it clicks into place, then repeat on the opposite end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

    • If you have a blank screen, white lines on the display, or partial or complete lack of touch response after reassembling your phone, try disconnecting and carefully reconnecting both of these cables and make sure they are fully seated.

    • 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.

    The right screw kept spinning, tried different levels of force but didn’t work. I left the screw on and bent the shield to get to the cable.

    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…..

    Therese Peffer - Reply

    Use the PH000 and apply a little more force before spinning, should come right out!

    Sierra Scolaro - Reply

    • Disconnect the front panel sensor assembly connector from its socket on the logic board.

    • This press connector should also be reconnected one end at a time to minimize the risk of bending.

  4. When removing the screen, be aware of the two tiny square black rubber grommets on the Penelope screw brackets that secure the screen. They can fall off very easily and be lost without even knowing it (it happened to me, but was lucky enough to find them).

    • Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray.

    • Press to eject the tray.

      • This may require a significant amount of force.

    • Remove the SIM card tray assembly from the iPhone.

      • When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

    • Remove the 2.2 mm standoff screw from the grounding bracket.

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

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.

Gabriele - Reply

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.

Judah Singh -

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 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.
