Introduction

The Taptic Engine produces your iPhone's vibration and haptic feedback functions. Use this guide to remove and/or replace the Taptic Engine in an iPhone 7 Plus.

This guide instructs you to remove the display assembly; this is intended to prevent damage to the display cables. If you feel comfortable removing the Taptic Engine without putting undue strain on the display cables, you can skip the display removal steps.

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.

  • Opening the iPhone's display will compromise its waterproof seals. Take extra care not to expose your iPhone to liquid damage after completing your repair.

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

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.

@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.

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.

Apply a suction cup to the lower half  of the front panel, 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.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Insert the flat end of a spudger into the gap. The watertight adhesive holding the display in place is very strong; 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.

Insert the flat end of the spudger between the front panel and the rear case at the lower left edge of the iPhone. Slide the spudger up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place. Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

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 delicate ribbon cables along the right edge of the device connecting the display to the logic board.

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.

Is it really safe to lay the device fully open like a book? The cable leading to the LCD gets stretched across the sharp edge of the aluminum edge of the back cover.

Generally I'd say no, it's not safe. In reality I've seen a bit of variance in the cable length, and sometimes it'll be fine—but mostly I'd be prepared to prop the display up or hold it in place at a slight angle so it doesn't put too much stress on the cables. On prior iPhones it was easy to rubberband the display to a box or a can of soda, and something like that would probably work well here too. Use your own judgment.

The tri wing screws are so hard to remove. What's the trick?

I am confused, please help. LOL the bracket, the very first one being removed. I see it has three screws the same size and one a different size? I've been trying to fix my daughter's phone and ordered a 0.6 mm Tri Wing screwdriver for iPhone 7 plus /Apple watch. It seems to fit the screws and it seems to be turning them although I can't see that well but they're not coming out. However when I used it on a smaller bracket with two screws they came right out so I'm thinking I don't have the right screwdriver I am at my Wit's End!! I have been working on this phone or attempting to for a while now. I cannot find a list anywhere of the exact size screwdrivers needed to Take apart an iPhone 7 plus. Any help would be greatly appreciated.

If your tri-wing screwdriver worked for other tri-point screws in the phone, then it should work for the screws you are struggling with! If it feels like the screws are spinning but not coming out, try to use tweezers to pull them out. I often struggle with tri-point screws, and need to apply some downward pressure to remove them. This can be risky though, as you do not want to strip the screw or damage components underneath the bracket. If you continue to struggle, you can give this driver and this bit a try.

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.

Use the flat end of 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 re-attach press connectors, press down on one end until it clicks into place, then repeat on the other end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

The note about the danger of pressing on the connector incorrectly is very legitimate. Though I find it more practical to use a wide (1.5 cm) case opener tool to press it down all at once. Minimizes risk of bending the connector.

Posted a comment above on the first step. The screwdriver that I ordered Works taking out these two screens shown in the picture. However it does not work on the first bracket that needs to be removed. It seems that all screw sizes are somewhat different but I'm not finding a list showing different screwdriver sizes needed. Does this make sense? Could anybody please give me some advice on this thank you much.

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.
