Use this guide to fix a faulty logic board in your iPhone 6s. Repairing a logic board may require micro-soldering.
A faulty logic board can also be replaced using the steps in this guide. 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.
You can also use this guide for reference to replace the logic board EMI shield stickers.
See this iPhone 6s iTunes Hardware Restoration guide to help fix your phone’s logic board.

Does anybody have more detailed instructions? Maybe in written form? I don’t know where to find the board and which tools I need. And did I understand right - he’s boiling the board, so he’s heating it up?

Hi, just got the repair kit that came with IPhone 6S battery. I felt that there’s no explanation on which tool to use to remove the two 3.4mm P2 Pentalobe screws. It’s not helpful just to say “Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector. “. It’s more important to explain how and what tool to use. The repair tool kit tools were not marked at all and it’s not right to assume that people know which tool or part to use. Please kindly address this issue. Thanks. Janet
Janet Monaghen -
@beingchen For the P2 pentalobe screws you should use the driver bit marked P2. Might be a little hard to see but it’s there, etched into the side of the bit.
Jeff Suovanen -
It’s very clear which tool you need. As it says these are “3.4 mm P2 Pentalobe screws” - so you need a 3.4 mm P2 Pentalobe screwdriver…
alexanderbrix1987 -
Just a P2 driver—3.4 mm is the length of the screw.
Jeff Suovanen -
If you can’t identify which screwdriver in the kit to use, you probably shouldn’t be working on your phone. Just sayin’
Keith Hockenbeck -
This is very useful

Is it ok to replace the battery if the phone screen is broken?
Reem -
Of course! As long as the screen and battery are disconnected from the motherboard, you can replace anything!
Charles Bejarano -
is it possible to change my battery on my iphone 6s and use a battery that has been already used in another 6s
morgan durnford -
Yeah it would work, but if the battery heath on the 2nd battery is bad, just get a new one.
Charles Bejarano -
@moe6802 Removing the battery can damage it, and it shouldn’t be used afterward. It may seem fine, but even minor battery damage can lead to a fire hazard. Not worth it for such a cheap part. If you need a battery, just get a new one.
Jeff Suovanen -
How do you discharge a battery? Do you just let the battery drain or is there something less time consuming that you can do?
Matthew Petts -
There is no easy way to discharge the battery in “less time”. Perhaps the fastest way is to play a visually-complex modern game or otherwise make your phone do a lot of work.
Lance J -
So my phone screen is completely black causing me to see nothing that is on my screen. And the battery is above 25%, near 100%. What do I do??
Jessica I -
you should post a question on the answers forum

I can’t the screws with the P2, seems that the screws are stuck, what can i do?
Alberto Jabiles -
My kit came with 3 screws. Are those to replace these 2 P2 screws? And what’s the third one for?
Daniel Morse -
If it came with 3 screws, then it’s an extra one just in case if a replacement screw gets lost.
Charles Bejarano -
My display is cracked/broken and not functioning. The slide bar doesn’t work. How do I shut down my phone?
Timothy Huss -
i have replaced several ipod batteries and laptop work, but these screws seem to loose but do not come out. how am i to remove them.shake the iphone?it seems the ioen is not in my kit, is that how to remove them?
this seems idiotic but i remember some other system magnets that firt make your screws easier to keep, but this might be changed….any video? this seems 1st step blues!!!!
makinfilms -
never ind ishook it… is that in the guide?….iopener is not in the kit……never was before is this an upsell? do i skip it? i dont have it
makinfilms -
My screws aren’t coming out either. I’ve loosened them, but they aren’t coming out. I’ve shaken the phone, given it some slight bangs…nothing.
Jesse Fisher -
The following info is not given until step 21 in the instructions, and probably too late at that.
DO NOT disconnect or reconnect any of the cables in this device until the battery itself has been disconnected!
Don’t skip that step, intending to do it at the end, as you may damage the phone.
ffissk -
2 thoughts:
1) Really? Steps 14-17 are about disconnecting the battery first, and step 17 notes “so it doesn’t get reconnected while you work.” How’d you get to step 21 and miss 14-17?
2) These pages are user-editable. (Probably (hopefully) “curated” by iFixit staff.) You should add a warning to step 17 (or step 24).

NOW THAT YOU’VE REMOVED 2 SCREWS, and
BEFORE YOU SNEEZE them into oblivion, or under the refrigerator (which is the same in many houses)
MAY I suggest:
1) Obtain:
— a piece of paper, such as normal printer paper (not too much writing on one side)
— a piece of tape, not too sticky, like masking tape (duct tape would be bad)
——— 1-1.5 inches (2.5-4 cm) wide
——— 6-8 inches (15-20 cm) long
— a pencil (or pen)
2) Put the paper on the side of your work area
3) Lay the tape, sticky side up, on the paper
4) Fold each end of the tape (~1 inch/2.5cm) back under itself, so the folded part faces the paper. Press the folded-back tape onto the paper
You now have Sneeze & Wind Insurance for your tiny bits!
5) Put the 2 pentalobes end down on the top end of the tape, next to each other. Push them a little onto the tape so they stick
6) Use your pencil to note on the paper next to the screws: “1. Pentalobes”
Now you may proceed with dissassembly, without worrying about telling the 1.5mm from the 1.6mm screws.
or about sneezing!

My phone has a bad battery and a bad connector and I wasn’t able to get all of my photos before it died. Is there any chance I won’t lose them when I replace the battery? Or, is there any way to charge a 6s battery with a bad connector?
Liz R -
There is a great chance that photos, which are stored to flash memory, which is solid state memory, which is not affected when power is lost, will be there, right where you left them, once you restore power to your device. You could install a partially charged battery into your phone and then retrieve the important things, like your photos, if you don’t intend to continue using the phone. Else look at replacing the lightning connector assembly. Here: iPhone 6s Lightning Connector Einheit austauschen
TimD -
The P2 is not getting the screws loose at all. I have tried this several times and no budge on my iPhone 6s.
Cassandra Vigil -
To avoid to be screwed by lost or mixed screws:
- Use magnetic pad, wipeable
- Write the ifixit- steps next to the screws (maybe even with their sizes) and other bits removed
with a non-permanent marker
- When finished, simply wipe the pad, and it’s ready for the next repair
Hope that helps.

I found a pentalobe 1 driver to work much better.
joelkevinjones -
The suction cup didn’t hold at all. I tried Windex and then hospital grade alcohol, but nothing worked. Finally had to use two exacto knife blades to begin lifting the screen. As soon as I got a little gap, used the spudger tool the rest of the way, The small philips driver didn’t fit the screws exactly, but with a little effort they came out. My battery adhesive strips snapped immediately and I had to remove the original battery the “hard way”. The kit came with replacement display adhesive but no explanation how to use it. I got some on - so better than nothing. Overall I’m happy with the results, and the new battery is charging now.
Daniel Wolf -
First step problem? Couldn’t get the screws out. I checked my other iPhone and realized the screws were missing!Just started prying it apart.
Hoyt Smith -
I went through the whole procedure, replaced the battery and got the screen back on. Then the 2 pentalope screws would not go into their sockets. They sink in all the way and spin, but it appears there are no threads to grab. The screen seems to be in position since I can insert a plug into the headphone jack without trouble. Did anyone else have this problem. Using the phone now with no screws. Yikes.
Walter Plante -
Hi Walter, in case you’re still dealing with this or anyone else has the same problem, check that the screw bosses on the bottom of the screen are straight and line up with the screw holes on the case. They should be at a 90° angle to the screen, but they’re easy to accidentally bend and could’ve gotten flattened against the screen.
Adam O'Camb -
I recommend a loop of tape attached to the table, and placing the screws on the tape in the order they were taken out. identifying the screws to put back is a simple matter of going the other way back up the tape.
David Taylor -
Did the repair for the second time, each time faster and easier. This steps by step is amazing and crystal clear no mistake possible.
