Replacement of screen on iPhone 3GS screen made by LaptopScreen.com
Background information
This is a guide to reinstalling the front assembly on the iPhone 3GS. The front assembly
contains the frame, the glass digitizer, and the LCD screen. We highly recommend
replacing the entire front assembly if any of these components need replacing. Tools you
will need are a flat and a Phillips screwdriver and a suction cup with a keychain ring
attached. You may also use a flat metal tool to pick open the bottom edge, but it is
best to use a suction cup
Open the iPhone
Using your Phillips screwdriver, remove two screws on each side of the docking connector.
Then place the suction cup right above the home button. Position your left hand thumb on
the top edge of the phone, right on the speaker hole. That is done in order to keep the top
edge in place. Otherwise, you may damage the logic board connectors by suddenly
separating the front assembly. Then pull on the ring with your right index finger while
leveraging your thumb against the chrome frame. You only need to pull until the bottom
edge separates a bit. Then pick the front assembly open with your fingers. Do not separate
the front assembly completely as there are few cables which need to be properly
disconnected
Open the connectors
Using your flat screwdriver, open the first connector. Underneath there will be a locking tab
connector which needs to be opened with a flat screwdriver and a third connector on the
right usually separates on its own, but you may need to pick it open with a flat screwdriver
as well
Separate the front assembly
Once all three cables have been disconnected, set the old front assembly aside
Connect the new front assembly
In order to reconnect the new front assembly, we recommend separating the orange flex
cable away from the other two connectors, then aligning it with the locking tab connector.
It goes in fairly easy if you hold the front assembly and simply push the flex cable
into the connector. Close the locking tab. Then press the other two connectors in place.
They make a distinctive click when plugged in properly
Close the iPhone
Once all three cables are secured, insert the top edge of the front assembly into the
groove on the top edge. And while holding it with your thumb, close the bottom edge.
Then replace the two bottom screws. Remove the protective film from the front glass.
And you're done
