    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

    • Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

    • Remove the metal handle from the suction cup. It's easier and safer to grip the suction cup's base instead of the metal handle.

    • Be very careful when opening the iPhone so that the cables under the display are not severed.

    • There is a rubber gasket between the silver front bezel and black display assembly. A bit of force is required in this step to separate the iPhone's display assembly.

    • Use a small suction cup near the Home button to gently pull up the bottom portion of the iPhone's display assembly.

    • If the display assembly is too damaged to allow the suction cup to adhere, tape with a strong adhesive such as duct tape, or thick, clear packing tape may be used.

Hi, thank you for the instructions! Maybe you can help. I'm tryin to recover data from a logic board of an iphone 3gs. I bought a working iphone 3gs and opened it, it now has a blue logic board. After replacing the blue to the green, the phone says 'connect to itunes' and does not start properly. Why are there two different colours of logic boards, what's the difference? Thanks for helping!
