Iphone 5 repair guide (written by me in 5 mins right now)
If glass is not too badly broken you can use a suction cup to pull the old screen away from the metal case.
If Glass is broken, use a flat head screwdriver or a thin knife to lever the bottom of the screen up.
Once its up you will see the ribbons are hidden under a metal plate held on with some screws, Undo these and lift the plate away.
Unclip the ribbons gently.
Now you will have two seperate items, the main unit and the screen.
You will need to remove various parts from the old screen, these are:
Metal Plate
Home button plate
Home button
Earpeice / top camera plate
earpeice speaker
top camera and speaker ribbon
camera plastic mount
First stage -
6 screws hold that plate in, 2 on each side and 2 on the main face.
Unscrew these and keep them safe.
Remove the 2 screws that hold the home buttons plate on
Take the plate off and attempt to remove the home button, WATCHOUT AS THE RIBBON IS GLUED, try and use a knife to seperate the ribbon from the screen very gently.
next remove the earpeice retention plate. two screws again, keep these in order as they are diff sizes.
Please be careful when removing the top ribbon, It can sometimes have the proximity sensor stuck in its little frame and can be ripped off if forced.
Once this is off you will see a small plastic ring attached to the screens glass, this makes sure the camera is aligned correctly and is good to remove and reglue to the new screen in the right place.
Now its all in reverse, Glue that ring on and wait to dry and fit the camera in place, Dont forget to pop the top Mic back into its rubber mount first
Put the metal plate back on (big one on back of screen)
Then you can screw the earpeice retention plate back in.
Then its the home button, stick that into place and screw its plate on (Must be the right way round or button wont work).
Once thats on you will notice the screw on the ribbon is still in place (if you didnt force it out when removeing it)
make sure the little metal bracket that moves on that screw is faceing the right way and screw it down to the mid plate.
Then its a matter of ligning it up and putting the connectors back onto the mainbaord, Watch out here cus if you push too hard you can damage the mainboard.
Then scre the plate back on and put the screen into place.
Once done put the two screws back into the bottom.
