Apple iPhone 7 Plus – Disassembling procedure – How replace the display

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  Phone.
Slightly warm up the lower edge of the phone to soften the adhesive holding the display in place.
Wait about a minute for the adhesive to warm up before proceeding.
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.
While pulling up on the suction cup, twist the spudger to widen the opening between the screen and rear case.
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.
Remove the spudger from the left side of the phone and insert the flat end into the bottom right corner.
Slide the spudger up the right edge of the phone to the top corner, breaking up the adhesive holding the display in place.
Pull up on the suction cup to lift up the display and open the iPhone.
Do not raise the display more than 10 degree as there are delicate ribbon cables along the right edge of the device connecting the display to the logic board.
Pull up on the small nub on the suction cup to remove it from the front panel.
Slide an opening pick underneath the display along the top edge of the phone to loosen the last of the adhesive.
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.
At this point you may lay the phone down on a flat surface like an open book.
Remove the following four tri-point Y000 screws securing the lower display cable bracket to the logic board:
Three 1.2 mm screws (red)
One 2.6 mm screw (orange )
Remove the lower display cable bracket.
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.
Remove the three tri-point Y000 screws securing the bracket over the front panel sensor assembly connector:
One 1.3 mm screw (Red)
Two 1.0 mm screws (Orange)
Remove the bracket.
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.
Remove the display assembly.
Remove the four Y000 screws securing the bracket over the home/Touch ID sensor:
One 1.1 mm screw (Red)
Three 1.3 mm screws (Orange)
Remove the bracket that secures the home/Touch ID sensor.
Disconnect the home/Touch ID sensor cable by carefully prying open its press connector.
Carefully pry up the remaining, bottom portion of the press connector, which is lightly adhered to the home/Touch ID sensor cable beneath.
Don't try to detach the press connector completely,simply separate the adhesive holding it in place.
Flip the display assembly over, and warm up the home/Touch ID sensor area for about 90 seconds.
Using an opening pick, carefully slice through the adhesive holding the home/Touch ID sensor cable to the back side of the display panel.
Remove the home/Touch ID sensor assembly.
