How To Fix The Five Most Common iPhone Injuries

iPhones aren't built to last forever, but that doesn't mean you should let a cracked display or dead battery finish your handset. We've got five of the most common repairs for the iPhone 4 - courtesy of our friends at iFixit.

How to Replace Your iPhone’s Rear Panel

Step 1: • Before disassembling your iPhone, be sure it is powered off. • Remove the two 3.6 mm Phillips screws next to the dock connector. (Apple has recently substituted the two Phillips screws with 5-Point "Pentalobe" screws. If your iPhone 4 has 5-Point "Pentalobe" screws instead of Phillips, please refer to the second picture.) • Remove the two 3.6 mm Pentalobe screws next to the dock connector. • During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws. • The 5-Point Screwdriver should only be used once, as it has the potential to strip the screws.

Step 2: • Push the rear panel toward the top edge of the iPhone. (The panel will move about 2mm.)

Step 3: • Lift the rear panel away from the iPhone.

Step 16: • Remove the small circular white sticker (warranty sticker and water indicator) covering the screw near the battery pull tab. • Remove the 2.4 mm Phillips screw that was hidden underneath the sticker.

Step 17: • Disconnect the following connectors from the top of the logic board: digitiser cable, LCD cable, headphone jack/volume button cable, top microphone/sleep button cable, front camera cable. • It is helpful to use the edge of an iPod opening tool to gently lift the connectors up and out of their sockets on the logic board.

Step 18: • Use a small flathead screwdriver to remove the 4.8 mm standoff near the headphone jack.

Step 19: • Carefully remove the logic board from the iPhone, minding any cables that may get caught. • Note that there is a rubber guard on the edge of the logic board where the digitiser and LCD ribbon cables bend over the logic board. Make certain it is there before replacing the logic board during reassembly.

Step 20: • Remove the single 2.4mm Phillips screw securing the speaker enclosure to the side of the inner frame.

Step 21: • Remove the speaker enclosure from the iPhone. • Before re-fastening the speaker enclosure to the inner frame, be sure the four small EMI fingers rest below the lip of the LCD frame. • Before reassembly, be sure to clean all metal-to-metal contact points between the EMI fingers and the internal frame as well as the brass screw mounting point with a de-greaser such as Windex. The oils on your fingers have the potential to cause wireless interference issues.

Step 22: • Remove the following two screws securing the vibrator to the inner frame: one 6mm Phillips, one 1.4 mm Phillips. • Remove the vibrator from the iPhone.

Step 23: • Remove the 1.5mm Phillips screw securing the front panel near the headphone jack.

Step 24: • Remove the three large-headed 1.5 mm Phillips screws along the volume button side of the iPhone. • Keep track of the washers under each of the screws. • Tip: It can be tricky, but it is also possible to just loosen the large-headed 1.5mm Phillips screws slightly, without having to remove and replace the screw-and-washer set.

Step 25: • Remove the 1.5 mm Phillips screw near the lower microphone.

Step 26: • Remove the 1.5 mm Phillips screw near the dock connector ribbon cable.

Step 27: • Remove the three large-headed 1.5mm Phillips screws along the SIM card side of the iPhone. • Keep track of the washers under each of the screws. • Tip: It can be tricky, but it is also possible to just loosen the large-headed 1.5mm Phillips screws slightly, without having to remove and replace the screw-and-washer set. • Remove the small-headed 1.5mm Phillips screw near the sleep button.

Step 28: • Carefully insert the edge of an iPod opening tool between the rubber bezel around the front glass panel and the steel inner frame. • Do not attempt to insert the tool between the glass and the rubber bezel. • Carefully pry the upper edge of the front panel assembly away from the steel inner frame.

Step 29: • Slowly and gently lift the top edge of the front panel assembly away from the steel inner frame. • Continue to rotate the front panel assembly away from the steel inner frame until it slowly begins to peel off the adhesive applied below the home button area. • Carefully pull the lower edge of the front panel assembly away from the steel inner frame.

Step 30: • De-route the digitiser and LCD cables through the steel inner frame. • Before re-fastening the front panel to the steel inner frame, be sure both the LCD and digitiser cables are not folded or pinched between the inner frame and the front panel assembly. This will result in possibly damaging the cables and not having enough slack when reconnecting the them to the logic board. • When the front panel has been correctly installed, both the LCD and digitiser cables should be immediately next to one another, and the connectors should be just hanging over the steel frame. • When replacing the front panel assembly you must remember that you might have to reuse the earpiece grille and the clear plastic ring around the front facing camera from the old/damaged assembly. This will depend on where you buy the replacement part.

Step 31: • Use the edge of an iPod opening tool or your fingernail to lift the home button ribbon cable retainer. • Be sure you are prying up on the cable retainer, not the socket itself.

Step 32: • Use a pair of tweezers to pull the home button ribbon cable out of its socket. • Do not excessively strain the home button ribbon cable, as it is very thin and delicate.

    There's a significant problem with these instructions, in that there's no instructions on reassembly.

    I know it may seem straightforward, but there are little peculiarities with reassembly.

    I clicked on the headline to see what sort of injuries iphones cause.

    I was disappointed.

    This article isn't excessively long at all.

    these instructions probably better belong on say, ifixit.com.

    Wow...this seems so straightforward now, but violates my personal rule that states that something which needs more than 20 steps to complete should probably be done by someone who isn't me.

    wouldn't you just look at the disassembly instructions backwards and reassemble that way?

    There are next to no little perculiarities with reassembly that I have stumbled across.

    When the iPhone 4 first came out and I repaired my first one I was freaking out because it seemed intensive compared to the 3g/s..... Now I would rather have a iPhone4 on the desk than a 3!!
