Remove or replace the pentalobe screws in an iPhone 7 Plus.

  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 at 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.

    The recommendation of discharging the battery is completely unnecessary. Even a 25% charged battery can explode. Completely ridiculous suggestion.

    The risk of thermal runaway on these batteries decreases with the battery's SOC (state of charge). Below 50% charge the risk is fairly low, and at 25% charge the risk of a thermal event is near zero. If I recall correctly, the same suggestion appears in Apple's official (non-public) service manuals for the iPhone.

    Jeff Suovanen -

    @jeffsu Yes, that is correct. Apple does require all certified staff to discharge the battery below 25%. This is an industry standard for all LiION batteries. If you don’t want to do this, just make sure to not puncture the battery and disconnect it first thing.

    Hang on a second here, doesn’t the Ifixit part I ordered come with the seals? The display assembly? It doesn’t. Now I have to wait another week?!

    How do you turn off if the screen isn’t responding to touch?

    The replacement battery came with the seal—but how do you put it on???

    I just found the instructions on how to install the seals AFTER I was completed and had to figure it out. Maybe, just maybe you should link this somewhere on the guild instead of buried in a comment. Just a thought.

    Step 1 is: Read through all the steps and comments or the method prior to starting on this Step 1. There's a lot of much needed information and experience that you can learn from which will reduce the chance of struggling, wasting time or even breaking your device.

    My favourites are:

    Use a hot water bottle.

    Label all screws you remove with their size and location on a piece of paper with double sided sticky tape.

    Test the lightning assembly at step 13

    There is a Standoff driver bit in the box, don't use a screwdriver.

    etc...

To reassemble your device, follow these instructions in reverse order.

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

Cooper Chase - crwdns2853112:0crwdne2853112:0

Hey Cooper,

There is no seal on the screw. The head of the screw simply pushes against the lip of the screw well, without using any sort of pneumatic seal, o-ring etc.

As Talon says, it is part of the casing.

Harry Rowse -

I not recall seeing one. If there is one I would expect it to be part of the casing.

as the costumer said, there is a sealant but not noticeable
