I suspect that the connectors on step 15 moved a little bit. Open again, click on the three connectors and it should work again.

And then on the Iphone 6s the original flex cable hasn't to be moved. Only the button itself because it is paired with the CPU.

Reply to Steve. Any reference for the limitation to 3.2TB? I am using a 4TB Green (same SATA bridge) without any problem since years now.

Would it be possible to tell us which 8TB did you choose. The replacement of my original 1TB to 2TB and then 4TB within the "green" series of Western Digital was fine. But in order to move to 8TB, I wonder why Western Digital stopped its green series. Green means that the hard drive stops when not used (which is appropriate for a backup drive like a Time Capsule). The red series does not stop, with higher comsumption and permanent noise. I also wonder why Apple doesn't propose any solution (I did not find any) above 3TB. Does it mean that above 3-4TB, this is the end of Time Capsule backup technology with the very Apple specific tools like tmutil and sparsebundle format? With higher capacity (8-10TB) and low rpm (5400RPM), backup and restore times are too long to be useful?

I was willing to add the following important remark on top of this guide but, strangely, it has been refused! Here it is:

---

*Check if your Iphone 5 is eligible to the Apple special program for a free battery replacement (devices sold between September 2012 and January 2013, within a limited serial number range).

* If not, watch the video and use this guide [video|https://www.youtube.com/watch?v=6ogE8USs...]

And thus, as my Iphone 5 was eligible, I went to the Apple store of Le Louvre in Paris and the battery has been changed for free instead of 65 euros. Thanks to Mark!

You are right. This is the reason why their is simpler guide: iPhone 4 Battery disconnection to be used when there is no necessity for removing the battery. Disconnection is sufficient for many fixes except replacement of the battery!

"If the Phillips screwdriver were magnetized, or if I'd had a pair of long tweezers, that would have gone a lot easier. "

Simply place any screwdriver a few minutes on a magnet to magnetize!

If the screw is not damaged by previous attempts, the screw driver should fit perfectly. You can also tap the screw with a small mass to unlock.

Thank you for the guide on the Camera replacement. However it is not necessary to remove the battery entirely but just to disconnect it. The battery is usually firmly glued and a lot of time is wasted. This guide on Camera replacement (3142) should not include the full guide "iPhone 4 Battery Replacement (3141)" but a shorter guide "iPhone 4 Battery disconnection (24135)" which I wrote. Unfortunately, my changes have be denied without any comment. In my recent edits of this guide (which have been denied too!) I also mentioned that when extracting the camera, you can unfortunately unplug some of the connectors located at the bottom right of the camera. They should be firmly plugged again otherwise (and this was my case) the Iphone may not power on. If you agree with my changes, could you look at my edits in the history of this guide and insert them again because they will answer to some of the general questions above.

It might useful to use a white sheet of paper and to circle each screw and its dimension and an indication of the corresponding Ifixit guide step #. It is then much easier to rebuild.
