Thank you very much for this tutorial! Thanks to it, I renewed my battery *and* my Lightning connector… and my iPhone 6 is working as if it was new. The operation wasn’t expensive at all and I can wait a little bit longer to buy a new phone. :)
I didn’t noticed the PDF guide for the screws but I made one myself and used some blu-tack to keep the screws in place. It worked fine for me and I did not have any issue while following this guide. (I started with the one for the battery replacement then switched to this one and it was perfect).
At last but not least, thank you (a lot) to iFixit for the parts and the (awesomely) fast delivery (in France)! The service is perfect from A to Z.
PS: for the antenna, I read the comments, took a deep breath and did as follow => with one hand, I placed the antenna connector in place (it looks like a target so it’s “easy” to center) then, once aligned, I pressed softly on it until I heard a “click”… and it was made in a minute or two. As for the rest of the process, it’s important to be patient, organized and keep its calm. (Of course, you should read and watch everything before your to proceed, at least the first time.)
