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.

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

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.

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…. =/

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.

  • 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 - Contestar

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.

Colton Neifert - Contestar

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

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.

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 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 :)

Steve - Contestar

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

Vegas Uprising -

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?

Sara Lee - Contestar

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.

Gabriele - Contestar

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 ….?

muhammed faisal - Contestar

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.

Adam O'Camb -

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.
