How to remove Rear Case

Insert a fingernail or plastic opening tool into the divot to the left of the rear-facing camera.
Gently pry and twist the flexible rear cover off the back of the phone.

Insert a fingernail or plastic opening tool into the recess in the bottom right corner of the battery and lift upward.

How to remove Display Assembly

NOTE: It is suggested to remove the battery, S Pen, SD Card, and SIM card (if your phone uses a SIM card).
Heat at a low degree such as less than 80 degree because the adhesive is not so strong. Heat makes it's easy, but you also can gave up heating and cut the adhesive sticker directly. Please be careful.

Cut LCD screen adhesive sticker carefully and slowly.

Be very careful once you get to the bottom part of the phone, take your time, and be very careful not to cut the flex of the Back and Menu buttons. Use the next set of images to examine how close they are to the edge so you don't accidentally cut them.

Insert the spudger underneath the LCD to cut the adhesive in the middle part. The adhesive is strong so make sure you are underneath the copper insulation before separating.

Notice 1: The adhesive is in the red line.

Notice 2: If you insert the spudger from right side, keep the length of the tool in less than 2.2cm, which is for avoiding damaging the home button flex.
Notice 3: If you insert the spudger from left side, keep the length of the tool in less than 4.4cm for the same reason.

Notice 4: Pay attention to the part with LCD screen flex. When you cut the adhesive, leave the top part alone to avoid damage the flex. But if it's the broken screen, you don't need to worry so much.

Be careful with the bottom side because there are the soft keys. If the adhesive in the red line don't function any more when you place the new LCD screen, you can choose to use the 3M double side tape. It can help to fasten the new screen together with the LCD screen sticker.

Release S Pen touch sensor film connector and LCD screen connector.

Remove the LCD screen finally.

How to remove Micro-USB 

Remove back cover easily. And take away the battery, SIM card and S Pen by the way.

Remove all together 16 screws from middle housing.

Free the clasps along the battery slot. And the push the front assembly out from middle housing with effort.

If want to remove motherboard, the LCD screen need to be removed at first. 3. The USB board assembly comes with two touch keys together but they are placed under the touch panel. So we have to remove the motherboard and LCD screen at first next.

Remove two pcs of signal flex cable and two screws which securing USB board and motherboard.

Release all the connectors connecting with motherboard.

Pry up the motherboard and release USB board connector from back.

Loosen the touch keys from adhesive at first. And then pry up and remove the USB board finally.

Apple iMac 27 – disassembling procedure

Apple iMac 27 – disassembling procedure – How to remove the front glass – How to remove the display – How replace the SATA hard disc

Apple iMac 27: disassembling procedure 

Stick a heavy-duty suction cup near each of the two top corners of the glass panel.
To attach the suction cups, first position the suction cup with the movable handle parallel to the face of the glass panel (as highlighted in the second picture).
While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle (as highlighted by the third picture).
If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a damp soft, lint-free cloth. (Dampen with distilled water, and if needed, an equal ratio of distilled water and white vinegar for best results.)
Do not use the suction cups to carry the display glass because if one of them fails to stick, you could drop the screen and break it.

The original iMac box makes a good place to store the glass panel. Otherwise, a padded horizontal surface, like a towel on a desk will do nicely.

Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

Pull the glass panel away from the lower edge of the iMac and carefully set it aside.
Don't use the suction cups to carry the glass panel if either one loses its grip, the panel could fall and break.
After setting the glass panel down safely, be sure to release the suction cups, as the suction force over time, can crack the glass.
During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Remove the eight T10 Torx screws securing the LCD to the outer case.

Be careful not to touch the display as the oil from your fingers may
leave a residue that can be difficult to remove.

If necessary, peel the EMI gaskets
located near the top center edge of the display assembly.

Carefully lay the iMac stand-side down on a flat surface.

Due to tight tolerances, you will have to use a thin hooked tool to lift the display out of the outer case. As seen in the first picture, we made one out of a bent paperclip.
Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.
After lifting the top edge of the display on one side, hold it out of the outer case while you use a hooked tool to lift the other side.
Raise and hold the display high enough to access the cables.
Do not lift the top edge of the display out of the outer case too far, as several short ribbon cables still connect the two components.

Disconnect the vertical sync cable in the upper left corner of the screen. Use the tip of a spudger to push on the connector's side tabs and gently walk it out of its socket.

This step bring your hands close to the exposed rear of the power supply. To avoid a high voltage shock from the many large capacitors attached to the board, do not touch the rear of the power supply.

Disconnect the LED back light driver cable with your hand by pressing the tab down and sliding it towards the bottom of the display.

Pull the black tab straight up to disconnect the latch on the display data cable ZIF connector.

Do not pull up too hard or you will damage the connector and socket. Continue to pull the black tab up toward the top of the device, to detach the display data cable.

Use the tip of a spudger to disconnect the display power cable next to the display data cable.

Carefully pull the display toward the top edge of your iMac and lift it out of the iMac case.

Disconnect the SATA power and data cables from the hard drive by pulling them straight away from the hard drive.

Remove the two T10 Torx screws securing the hard drive to the iMac frame. Slightly rotate the top edge of the hard drive away from the outer case. Lift the hard drive off its two lower positioning pins and remove it from the outer case.

Remove the two T8 Torx screws securing the upper bracket to the hard drive. Remove the upper bracket from the hard drive. Remove the two T8 Torx pins from the other side of the hard drive.

Carefully peel off the piece of EMI foam attached to the front of the hard drive. Don't forget to transfer this to your new hard drive.
