Image 1/1: Power off your iPhone before beginning disassembly.
  • Before you proceed, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

  • Power off your iPhone before beginning disassembly.

  • Remove the two 3.8 mm P2 Pentalobe screws on either side of the Lightning connector.

to keep screws in order, buy some double sided tape and then affix the tape in small pieces to a sheet of paper. As you take the screws out, you can affix them to the tape (which is on the paper) and then write a description of what they are and where they go. quick, cheap and easy.

  • The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 5c that we recommend for anyone doing more than one repair on an iPhone 5, 5s, or 5c. If you aren't using the iSclack, skip to Step 5.

  • Close the handle on the iSclack, opening the suction-cup jaws.

  • Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.

    • The top suction cup should rest just above the home button.

  • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

  • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

  • With a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while you pull up with the suction cup.

  • There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Cover a badly cracked screen with a strip of packing tape first to get a better seal for your suction cup. If it's a super crappy suction cup, moistening it a bit will help as well.

  • Remove the two 1.6 mm Phillips #000 screws securing the metal battery connector bracket to the logic board.

These screws are very tiny and hard to manipulate. The screwdriver is magnetic; which is great to take them out, but makes it hard to put the screws back in, as the screwdriver pulls them from the hole. I solved this problem by using the pointed end of the spudger to put a tiny drop of Elmer's glue in the hole and then insert the screw. You can do this before putting the bracket in place if you want. Then the screw wont pull out by the magnetic driver and make lining up and fastening the screws much easier; at least for me!

I found that you don't need to disconnect the battery... why bother doing more fiddling with annoyingly tiny screws and obstinate cable connectors when you don't actually have to? Especially when you could only end up causing more damage. As a matter of fact, the original iFixit video didn't bother to disconnect the battery either, but they've since updated the video to include battery disconnection, I guess as a "belt and braces" approach in case the repair-hero forgets to power down the phone first?

Michael Allen - Reply

Disconnecting the battery is a safety precaution, and yes it's worth doing. Even with the phone powered off, there is some danger of blowing the backlight filter fuse if you disconnect the display while the battery is connected. At that point you're no longer looking at a simple DIY repair. Even though it's possible to skip this step and still come out okay, my advice is not to risk it.

Sorry, I missed the comments on step 9 that detail the procedure.

Maria Raesch - Reply

Image 1/1: Two 1.3 mm screws
  • Remove the following Phillips #000 screws securing the front panel assembly cable bracket to the logic board:

    • Two 1.3 mm screws

    • One 1.7 mm screw

    • One 3.25 mm screw

  • It is especially important to keep track of your screws in this step for reassembly. Accidentally using the 3.25 mm screw or the 1.7 mm screw in the bottom right hole will result in significant damage to the logic board causing the phone to no longer boot properly.

  • Be careful not to over-tighten the screws. If they don't fit easily when you are securing them, they may be the wrong size, don't force them.

In step 9: I think you are talking about the 3,25 and 1,7mm one not the 1,3 and the 1,7mm?

DO NOT Remove the battery, there is no need to and can cause unnecessary damage! There's a tutorial on YouTube that does it without!

Alister Malcolm - Reply

I didn't need to remove the front panel to replace the lightning connector. Just prop it up like in Step 8, then skip steps 12-16.

I always put my screws in a magnet tray and place the screws in the exact position they were taken out. The magnet tray holds the screws tight in the position I put them in. No chasing on the floor looking for small screws that you brushed off the table.

Fredrick Apel - Reply

I always take a picture of the phone, print it out, then use scotch tape to tape the screws onto the picture in the location where they go. You don't lose the screws and you always know where they go for re-assembly

When reassembling, the screw holder that the screws screw into came off the board. Is there a way to superglue that back in?

I replaced the broken front panel of the iPhone 5c and got the "famous white stripes" on the new screen. Reading about all kind of problems that the lcd/digitizer cable contacts may cause, I compared the cable connectors of the original Apple and the replacement part I bought online with a 35x magnifying glass. The quality difference was visible: The white description on the original part on the cable next to the connector is: 821-1784-A, while the inferior replacement part is: 821-1784-02. Check out the two numbers online and insist getting the "A" to avoid future troubles !!!

This person above is not knowledgeable. That number is a camera proxy part number, not the lcd or digitizer number. It changes with production date, both for original and aftermarket ones. A, B, D, 02, 04, 08 etc. Can all be either or.

vince -

Apple uses numerical revisions (-02) for pre-production parts, and alpha revisions (-A) for production revisions. It looks like you got a preproduction assembly, or a knock-off.

There are, in fact, three connectors in this step, not two. The front-facing camera and digitizer connector (Step 11) is really difficult to align when you put it back. Took me about 15 minutes before I succeeded.

Now I have a different problem. Everything works just dandy, EXCEPT:

Towards the bottom of the screen (in portrait) there is a horizontal line that is dead to the touch. For example, on the keyboard, I can use the spacebar, but not C V B N M, etcetera.

Three possibilities in my mind: One, when I dropped it, something else besides the glass and digitizer, etc, was damaged.

Two: I did not replace the cables correctly. This seems unlikely. They all "clicked" into place and stayed there.

Three: The digitizer supplied is faulty.

Comments? Which cable/connector could be causing this -- if it is that?

Take apart, Clean Connections, Put back together.... If same problem sounds like a fault part...

When reassembling the iPhone 5c, I used the flat end of the spudger to press on the connectors and maintain them while replacing the front panel on the body of the iPhone.

The third and "deepest" connector no longer slips out of its socket, which it did before holding the whole lot with the spudger.

If the ESD plate covering the connectors is properly re-attached to the phone, you should not have to do this. The cover holds all the connectors in place just fine.

Would a logic board swap be easier than a battery swap between 2 iPhone 5C's? ?

Dylan Tran - Reply

A battery swap would be significantly easier! Here's the battery replacement guide. =)

Sam Lionheart -

While I was repairing my phone, I guess the part where I didn't go around was taking out the battery because it felt like it was the more fragile part. This was because I did not have the proper equipment to take it away. This guide was pretty helpful for me in reconnecting cables.

Anyway, I am bothered that as I took out the logic board, there was this golden thing that just slid out of place. It slid from the top portion of the phone, but I do not know where it was originally and I do not know how it was supposed to be placed. It looked like an open box of sorts (but only had 3 sides bent up) and had a hole in the middle. It would be great if anyone would know where it could be placed so I could put back my phone.

Did everything as described and it all went good except for the antenna which I had a hard time connecting back and then it broken, I will have it welded back on.

However when I tried to turn on the phone, nothing happens! Stays black!! What can it be?... help !....
