5. REMOVING THE BOTTOM BEZEL SCREWS Make sure to: • Check to see which type of screw your iPhone has on the bottom, some of the older units use regular #00 screw heads, and others use the proprietary Apple Pentalobe screws. • Try and un-screw these carefully, we do not want to

6. REMOVING THE BACK COVER Make sure to: • Slowly slide it up, we do not want to damage the mid frame, or the plastic frame around the edge of the cover. • Make sure to place the backing in a protected space, so we do not damage or scratch the back in any way.

7. REMOVE THE BACK COVER COMPLETELY Make sure to: • Be careful with the black clips on the edge of the back cover, these are what help keep the back in place. • As you pull the cover out, check for the water damage icons on the bottom left above the battery plug in, ALWAYS NOTE WATER DAMAGE before moving on with the repair in your

8. REMOVE THE BATTERY AND INPUT SOCKET Make sure to: • Carefully remove the screw, this is what holds the entire battery input socket into place during normal falls and wear and tear, not securing it can cause the phone to become inoperable.

9. REMOVE THE SOCKET FOR THE BATTERY Make sure to: • Carefully pull up with a plastic pry tool or your spudger, DO NOT USE A FLAT HEAD SCREW DRIVER, this can cause the whole socket to come up and then the entire board is damaged and has to be re-soldered on. • Make sure to remove the black lever that the screw and socket held

10. REMOVE THE BATTERY COMPLETELY Make sure to: • Remove the battery using the plastic grip tape that is coming out of the left side. • Pull up slowly, there is adhesive on the back, and we do not want the battery to be completely misshapen. • Make sure to keep all the components of the battery together!

11. REMOVE THE SIM CARD TRAY Make sure to: • Remove the sim card tray properly, you do not want to push to hard and bend or break the metal lever on the inside. • Always do this before attempting to take anything else out of the phone, the sim card tray also works to hold the board into place, and you can damage the copper points if removal is too hard.

12. REMOVING THE BOTTOM DOCK RIBBON SCREWS AND THE PLATE ASSEMBLY. Make sure to: • Remember that the screw on the left that connects to the mid-frame is different from the one on the right, it is smaller and has a flatter head. • When removing the screws, make sure to keep them aligned with the plate on their appropriate sides so you do not forget which side is which.

13. REMOVING THE DOCK RIBBON Make sure to: • Carefully remove the dock ribbon, and bend it VERY slightly to the left and out of the way, as sometimes it will get in the way when removing the other pieces. • DO NOT USE A FLATHEAD SCREWDRIVER, this can have negative effects and cause the dock ribbon to stop working, better bust out the

14. REMOVE THE ANTENNA AND SPEAKER PIN Make sure to: • Not use a flathead! We do not want to damage the pinion or the pin hole that holds it into place. • When you remove it, pull it up and to the right and out of the way.

15. REMOVE THE LEFT SIDE DOCK SCREW Make sure to: • Remove the screw carefully, and remember that it is a completely unique screw from the others inside of the assembly of the phone, keep it with the other screws that connect the board to the mid frame, in order from bottom to the top.

16. REMOVE THE BOARD SOCKET HEAT PLATE Make sure to: • Remember that each one of these screws Is unique and serves a specific purpose on the integrity of the build of the phone. • When removing, start from the left, and then pull the plate out carefully, aligning it to the layout of the screws, so you do not forget what point they go in, they are not all the same size either.

17. REMOVE THE PLATE THAT COVERS THE TOP BOARD SOCKETS AND THE ASSEMBLY Make sure to: • Carefully pull up and down, making sure not the bend the plate in anyway, as bending it can cause the LCD assembly to sit improperly inside of the phone. • Place it in a neat and organized manner with the screws so that everything lines up correctly for re-assembly.

18. REMOVING THE CAMERA AND RIBBON FLEX Make sure to: • Carefully pull up on the ribbon flex, sometimes the two layers can come undone, and cause the camera to come apart, and you will not be able to put it back on. • Clean the camera as you pull it out with compressed air for dust. • DO NOT USE A FLATHEAD SCREWDRIVER.

19. REMOVE THE MID BOARD SCREWS Make sure to: • Check the other water damage indicator strip, it actually covers the screw and will need to stay on the screw, so carefully unscrew it without damaging the indicator • This is the main screw for holding the board to the mid-frame

20. REMOVING THE TOP RIBBON FLEX’S Make sure to: • Remember that this part is a little tricky, each ribbon flex has a specific duty, and needs to stay in the correct order in order to reassembly the phone. • The red ribbon flex is for the digitizer ribbon, pry upwards from the bottom • The orange ribbon is the LCD ribbon, pry up from the bottom right side • The yellow ribbon is for the Head phone jack and the volume key ribbon, pry from the top • The green ribbon is for the top microphone/on-off button, pry from the top

21. REMOVE THE TOP BOARD BRACE SCREW Make sure to: • Use a flathead mini screwdriver, this one is very integral to keeping the board in place, and is also used for a thread for one of the screws for the plate that covers the main ribbons and the sockets.

REMOVING THE IPHONE 4 BOARD FROM FRAME Make sure to: • Remember that the sim card tray must be removed before taking the board out. • Life from the bottom and up, making sure not to damage the copper prong that is on the top of the board. • Once you life it up from the bottom, pull it back from the bottom to

23. REMOVE THE BOTTOM SPEAKER ASSEMBLY SCREW Make sure to: • Carefully unscrew it, and make sure that you do not damage the copper plate holder, as this helps hold the assembly down. • Pull the black speaker housing after you have unscrewed it from the right side and pull up and out. • Make sure to clean and not damage the metal prongs on the top of the assembly, these prongs help hold it into place.

24. REMOVE THE VIBRATE MOTOR Make sure to: • Remember that the red screw is a longer screw that holds the vibrate motor and the headphone jack in the same place at the same time. • The orange circled screw holds the vibrate motor to the metal frame so that it doesn’t shake around inside of the phone.

25. REMOVE THE TOP RIGHT CORNER FRAME SCREW Make sure to: • Remove this screw, it is ¼ and they are all the same size. • It is easier to start with this one first because it appears right after you remove the vibrate motor. • Keep it organized and layed out, although all 4 screws are the same size so they do not have to go from where they came from.

26. REMOVE THE VOLUME KEY FRAME SCREWS Make sure to: • Remove these screws carefully. • Keep them all together they are all the same size, but will not fit any other screw thread correctly, so you do not want to incorrectly put them together.

27. REMOVE THE BOTTOM RIGHT CORNER SCREW Make sure to: • Keep this with the other screw from the top right side • Look to the left of the screw in the opposite corner, we will remove that one next.

28. REMOVE THE BOTTOM LEFT CORNER SCREW Make sure to: • KEEP THIS WITH THE OTHER CORNER SCREWS • Sometimes you have to move the board around, making the bottom the top in order to correctly remove it without stripping it. • These screws are important in keeping the LCD on the frame, so do not lose them! Always replace them if one is lost, NO MISSING

29. REMOVE ADDITIONAL FRAME AND CORNER SCREW Make sure to: • Start from the bottom screw circled in red, these go with the other screws and there is three more on the opposite side of the frame that need to be removed • The top orange screw is for the corner and needs to be completely removed • To save time, just unscrew the six mid-frame screws slightly so that they uncover the brackets for the LCD display and keep them on the frame itself.

30. REMOVING THE LCD FROM THE MIDFRAME Make sure to: • Heat up the edge of the display slightly, just to get the adhesive to rise up a tiny bit, the start with your plastic pry tool and push up, making a gap between the LCD and the mid frame. • Never use a flathead, you can scratch the mid-frame. • Don’t try for a huge gap, just enough to pull it out with your hands

31. REMOVE THE LCD FROM THE MID-FRAME Make sure to: • Pull gently, you don’t want to rip it off. • Start from the top side and route the LCD and digitizer cables through the hole in the mid frame, make sure not to snag it on any of the other flex ribbon heads

32. CLEANING THE COMPLETE FRAME Make sure to: • Clean the mid-frame bezel with the green side of the sponge, this keeps the brush metal look going, and makes the phone look better then it did when it came in! It also helps take off some of the adhesive that may be left on the bezel.

33. PUTTING NEW LCD ASSEMBLY ON Make sure to: • Completely remove the tape from the backside of the new LCD assembly. • This tape is used for the heatsink sheet that’s on the back of the LCD, if it gets scratched, you will be able to see it through the LCD when the phone is on.

207. REMOVE THE BLACK TAPE COVERING THE VOLUME KEY SCREWS Make sure to: • Check to see if it is there first, sometimes if the phone has already been repaired, it is missing. • It is not integral to the functionality, and if it is ripped or torn, it will not degrade the product or assembly in any manner, but always try to keep it intact for reassembly.

208. REMOVE VIBRATE SWITCH ASSEMBLY SCREWS AND VOLUME KEY PLATE SCREWS Make sure to: • Keep track of each screw, the top red one near the vibrate switch is integral to keeping the switch in and aligned correctly. • The orang and yellow screws are different sizes from everything else as well, and the bottom two screws are the same size, all of them are needed to keep everything aligned correctly, DON’T

209. REMOVING THE VIBRATE SWITCH BRACKET COVER Make sure to: • Grab a pair of tweezers and pull this bracket off, its what keeps the vibrate switch in place and popped out so that it can be easily switch on and off. • Make sure not to bend the lever arm, and look at the direction it which it faces, this will help you remember how to put it back on.

210. REMOVE THE RIBBON ASSEMBLY OUT Make sure to: • Grab the headphone jack with the pair of tweezers, this is the best point to pull the whole ribbon off, because we are replacing the whole ribbon, don’t be scare if any of it rips, just make sure to take it off and make sure the placement is clean for the new ribbon.

211. REMOVE VIBRATE SWITCH BRACKET CRADLE AND THE METAL VOLUME BUTTON FRAME Make sure to: • Use a plastic pry tool to remove it from the actual vibrate switch, it’s the cradle behind the metal rectangle with the black dongle (the actual vibrate switch) We need the cradle to be perfectly cleaned for the new ribbon • Do the same thing for the metal volume button frame, just peel of the pop caps • We need to reuse both of these pieces for the new ribbon assembly.

212. INSTALLING THE NEW RIBBON AND REASSEMBLING THE PHONE • • • • • Now that we have vibrate switch cradle, take the new ribbon and make sure that the switch is on the bottom part of the rectangle, that way when we put the new bracket in and put the actual vibrate switch into place, it will correctly move up and down. The new ribbon assembly should have adhesive on the back of the actual switch, make sure you press it into the metal cradle correctly, pushing down hard so that it doesn't’t come off when we assemble the phone. A tiny spot of glue, literally the size of a pin head can be used as well if your worried it will come off. Wrap the new pop caps for the volume keys around the metal frame, keeping them in their correct position, the new ribbon will guide you on how it sets on the bracket. Now take the vibrate switch bracket, the one that goes on the outside of the vibrate switch cradle, grab the upper screw we took off, put it on the end of your screw drive and through the arm screw hole, hold the vibrate switch into place and screw the metal bracket into place, then do the next screw. Test the vibrate switch and make sure it goes on nice and tight, but maneuvers fluidly up and down, if it doesn't’t, take it out and do it again Now assemble the screws for the volume key, sit the headphone jack into place, making sure it is glued down all the way. Now reassemble the phone working backwards and make sure to double check all the buttons before continuing

240. REMOVE THE TOP HEADPHONE JACK SCREW Make sure to: • Remove the screw and lay it out in the correct position, this one is specifically sized for holding the headphone jack into place.

241. REMOVE THE ANTENNA CONTACT POINT ABOVE THE HEADPHONE JACK Make sure to: • Use a plastic pry tool to remove the antenna contact point that is at the top right of the phone, directly to the right of headphone jack. • Try not to rib or damage the antenna contact point.

242. REMOVE THE MICROPHONE PLATE FROM THE SMALL CADDY ON THE REAR CASE. Make sure to: • Use a plastic pry tool to remove the top microphone plate from its metal caddy, its ok if it rips off, the new ribbon we are replacing it with has it installed on it as well • Make sure to clean all the adhesive out of the caddy so that the new microphone will sit nice and snug inside of it.

243. REMOVE THE OUTER ANTENNA SCREW Make sure to: • Remove the headphone jack assembly first with a plastic pry tool • Remove this screw gently, we do not want to strip or damage the threading on the inner case, without this the iPhone will experience signal loss for data and voice calls. It is located to the right of the headphone jack after you pull it out.

244. REMOVE THE ENTIRE OUTER ANTENNA CABLE Make sure to: • Pull this out in one piece, we do not want it to rip as we are going to use it again when we put the new ribbon assembly together. • Keep it next to the outer antenna screw we undid.

245. REMOVE THE VIBRATE SWITCH AND VOLUME KEY SCREWS Make sure to: • Keep all these screws together, they are all the same size and are imperative when putting the vibrate switch assembly and the volume key assembly when we put the new ribbon inside of the phone.

249. REMOVE THE METAL VOLUME KEY FRAME Make sure to: • Use a plastic pry tool to remove the volume pop caps from the metal frame, we are going to reuse it so make sure it is cleaned of adhesive so nothing will cause tightness on the volume keys when pushed.

250. REMOVE THE VIBRATE SWITCH FROM THE CADDY Make sure to: • Remember that this one is setup a little different then the iPhone 4 GSM model, there isn’t a metal caddy cover that holds it into place, so the metal caddy itself is what keeps the vibrate switch in its proper position.

251. ASSEMBLING THE NEW CABLE AND INSTALLING • Now that we have the entire cable out of the phone, the outer antenna removed, the vibrate switch caddy and the volume key frame, we can assemble the new ribbon and install it • There should be adhesive on the volume key pop caps as well as the vibrate switch caddy. • Install the volume key frame making sure to keep it in the correct direction, or the pop caps will not sit correctly, look at the volume key frame disassembly picture to get a better view. • Use a small, pin sized amount of glue to put the vibrate switch caddy onto the new vibrate switch, on top of the adhesive that is already on the new ribbon • Align the vibrate switch correctly, making sure it is in the down position when inserting it, then put the screw in and test the vibrate switch to make sure it is tight, in place, and doesn't’t feel too tough. • Now install the headphone jack again, making sure to slide the microphone tab in just to the left of it, it should be connected already to the headphone jack • Now secure the volume key frame and test the buttons! • Reassemble the phone working backwards from the disassembly steps.
