This tear down and these comments were my lesson to read ahead here. My phone has been in pieces because I do not have the finger to get the antenna cable back on. REALLY wish I would have seen these comments and skipped these steps.

Headphone gasket? I guess I lost that. A picture of the items we need to be careful with would be helpful.

In vernal the guide is good but I also couldn't believe there were no steps for reassembly. AlsoI have noticed several comments that contradicted what was in the guide. I think they have updated the guide. I would hope.

Every step after this one is vague and hard to understand. Seems to be a lot missing. Proceed with extreme caution!

In my opinion spudger form the left side lifting to the right.

This is important and left out.

First Connector - Lift from the top of the phone to the bottom.

Second Connector - From the top right corner of the connector lift straight up. It will go to the left.

Third Connector - Hold the second cable back and again lift from the top right corner of the connector and it will go to the left.

This is hard. Tab broke pretty easy and a hair dryer did nothing. I put a plat in the microwave with a large bowl of water under it. Heated it till I could barely touch it and then laid the phone on it. Make sure the plate is big enough for the whole back of the phone to touch it. Leave it on a few minutes and the phone should get pretty hot but still touchable. I GENTLY pried at the top and on the outside edge and it came out fine. Patience is a huge virtue on this step.

This is the tricky part if there is one. Just pull back towards the battery and not up.

This is easy! I have no idea why they marked it moderate. Buy the tools they sell. Buy the battery from them and do it yourself. Much cheaper and much easier than anywhere else. Did I mention it is easy? Just make sure you follow the instruction on pulling the battery cable and it will be EASY.

That tab broke pretty easy on me. Use some heat. Seems like I am taking a lot apart to get to the lightning connector.
