    • Pull up on the exposed clear plastic tab to peel the battery off the adhesive securing it to the iPhone.

    • If the tab breaks before the battery is freed, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery. Wait about one minute for the alcohol solution to weaken the adhesive. Carefully slide a spudger under the battery tab to release the adhesive.

    • Prying in other places may cause damage. Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • Remove the battery.

    • If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the the ribbon cable.

    • Before reassembly, clean metal-to-metal contact points with a de-greaser such as windex. The oils from your fingers have the potential to cause wireless interference issues.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

    • Use the edge of a plastic opening tool to gently pry up the display assembly around its perimeter.

    • Press gently on the home button to push it through the display and make sure it stays behind as the display separates from the iPhone. Otherwise, the home button cable may tear.

    • De-route the digitizer and LCD cables through the steel inner frame.

    • When reinstalling the display, carefully straighten the digitizer and LCD data cables, and feed them through the slot cut in the steel frame. This photo shows the display assembly being installed incorrectly, with a fold in the digitizer cable.

    • When the front panel has been correctly installed, both the LCD and digitizer cables should be immediately next to one another and should be the same length, as shown in the second photo.

    • If the digitizer cable has been installed incorrectly, it will not reach its socket on the logic board. Do not attempt to pull it through by force, or it will tear. Remove the display assembly, straighten the cable, and feed it through to its full length, as shown.

    • During reassembly, do not touch the metallic area at the base of the LCD data cable, as this can cause problems with the LCD. If you do touch it accidentally, clean it gently with an alcohol wipe before continuing.

    • Remove the display assembly from the iPhone.

    • Be sure to separate the home button from the front panel. If the home button sticks to the front panel you may tear the home button cable.

    • When replacing the display assembly, note the following:

    • You may 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.

    • Your replacement display may come with colored plastic film on the back of the LCD. If so, use the pull tab near the home button to peel the plastic film from the LCD before installing the new display in your iPhone.

    • After reassembly, note the following:

    • Clean the touchscreen surface with an alcohol wipe prior to turning the iPhone back on. The alcohol helps dissipate any lingering static electricity, which can cause problems with the display.

    • After reassembly, connect the iPhone to an AC power source before turning it on for the first time. Once the iPhone has booted up successfully, you can disconnect the AC power.

Its a good note to posted's and label where the screw is from, since they are so small and a pain to remember where its going.

The Digitizer Cable seems to be too short. Trying to make it reach. It doesn't reach its place on the logic board. Going to disassemble and start over. (Step 15)

Any pointers?
