The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 Plus that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip to Step 4.
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 Plus.
Close the handle on the iSclack, opening the suction cup jaws.
Place the bottom of your iPhone in between the suction cups.
Position the iSclack's upper suction cup against the display, near 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.
