Step 2 iSclack Opening Procedure

Edit
Image 1/1: If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6.

  • The next three steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip to Step 5.

  • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6.

  • Close the handle on the iSclack, opening the suction-cup jaws.

Step 3

Edit
Image 1/2: Position the iSclack's upper suction cup against the display, just above (but not covering) the home button.

  • Place the bottom of your iPhone in between the suction cups.

    • Position the iSclack's upper suction cup against the display, just above (but not covering) the home button.

  • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

Step 4

Edit
Image 1/2: The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the display cables.

  • Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case.

  • The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the display cables.

  • Peel the two suction cups off your iPhone.

  • Skip the next three steps and continue on to Step 8.

The iSclack opened the iPhone 6 with little effort. I could have given even less opening pressure than I did. Fantastic tool. Worth the investment.

Step 5 Front Panel Assembly

Edit
Image 1/1: Press a suction cup onto the screen, just above the home button.

  • If you don't have an iSclack, use a single suction cup to lift the front panel:

    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is pressed securely onto the screen to get a tight seal.

This is nearly impossible on a screen that is shattered

Step 6

Edit
Image 1/1: Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

  • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

  • Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.

  • There are several clips holding the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Pulling up on the suction cup helped get me started, but what worked for me was pulling up gently while sliding the plastic prybar gently along the seam towards the top of the phone (on both sides), and it came open without having to put excess pressure on the suction.

Step 8

Edit
Image 1/3: Several clips along the top edge of the front panel form a partial hinge.

  • Open the iPhone by swinging the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge.

    • Several clips along the top edge of the front panel form a partial hinge.

    • During reassembly, align the clips just below the top edge of the rear case. Then, slide the front panel upward until its top edge is flush with that of the rear case.

Step 9

Edit
Image 1/3: In a pinch, an unopened canned beverage works well for this.

  • Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.

    • In a pinch, an unopened canned beverage works well for this.

  • Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

These screws require a Phillips #000 not Phillips #00 bit.

Image 1/1: Three 1.2 mm screws

  • Remove the following five Phillips screws securing the front panel assembly cable bracket:

    • Three 1.2 mm screws

    • One 1.7 mm screw

    • One 3.1 mm screw

3 comments

Be careful when replacing the screws, not to accidentally put the 1.7mm screw into the center hole, where the 1.2 screw belongs. This can cause "Long Screw" damage, and render your phone unusable.

I don't have the magnetic pad but use duct tape face up in a tray. I write the step number and color of the screw on the sticky surface and let the screw stand heads up on the goo. The screw is presented for the driver when reassembling.

griffn - Reply

Can't stress enough how important it is not to mix up these screws! Using the 1.7mm screw for the lower left fixing will cause "long screw damage" and kill the backlight on the phone. I believe @damianodessgillett made the same point. Wish we could display a small warning message here to be extra careful for future fixers!

Reassembly was harder than other i devices I have worked on. A bench light from the side helped a lot with the first cable, the digitizer. The others went a bit better in this crowded space. I had screen lines when testing it out before closing the top, so reinstalled all four connectors here with the aid of a side light and happily, that worked!

I have assembled an iPhone 6 and it seems that everything goes fine except the NFC. The phone does not respond to the POS when using Apple Pay. I think there should be some poor connection between the logic board and NFC antenna. If so, which screws should I scrutinise to fix this problem? Thank you.

Make sure to tighten these screws well when reassembling so you don't have issues with cellular reception. Had a phone that wouldn't connect to cellular connection after a screen replacement. I tightened the screw and it started working again.

If you got those strips you will have to remove the screen again and make sure you're plugging properly all the flex cables to the lógica board. Try to push them from the right to the left side.

is there a way to swap only the memory component instead of the whole thing?

jonesandrew1414 - Reply

Yes, you can, but you will need to have some serious soldering skills. But in theory you can replace the memory chip with another memory chip that has been reprogrammed to fit your phone's serial number.

make sure you have connected the digitizer 1 lcd 2 camera 3 home button is 4 . the camera lead must over lap the lcd cable otherwise the cable retainer will not fit properly because the cable will cover the screw hole of the cover hope this helps.

I did the same thing, and everything is working great now, except I am also not able to use the letter "Y" in portrait. Have you figured out a fix?

If someone says you need new logic board, try fixing to board first. Try iPad rehab, iFixLogicBoards, Powerbookmed etc. These logic boards are expensive and sometimes they come iCloud locked :(
