Hmm. I hope to add a comment that actuallyally informs, as opposed to criticizes. When reassembling, there are two tabs on the hard drive bracket that slot into slots on the logic board. Take care to re mount the bracket properly, or things wont fit later in the reassembly.

If you don’t have a nut driver, loosen the standoffs with needle nosed pliers, and then thread a screw from one of the earlier steps into the standoff until it is snug, then unscrew the screw and the standoff as one.

When reassembling, don’t forget to re run the audio cable through the hole in the EMI shield, the one just above the screw with the orange circle on the left side of the picture. Ask me how I know.

As Mateo said, replacing the zif cable is NOT easy, and in this case, will leave you with a computer that won't power on- this cable connects the power button. I learned a trick somewhere for dealing with these cables- put a piece of good sticky tape on the cable, and use it to pull it back into the connector. Works every time.

I am confirming from experience and also a discussion in the ifixit answers section (MacBook 5.1 temperature sensor missing?) that not all (few in my experience) 2009 macbook 5.2s have anything connected to the TEMP J5550 connector at the seven oclock position in relation to the fan. It is simply empty.

When I did this the ribbon cable beneath the plate stuck to the plate, and this guide makes no mention of this cable at all. Be aware that it has to be re routed and re attached to its positions on the logic board or your phone will not work, as i looks like some kind of RF cable.

you probably didn't reconnect the wifi antenna connector very well if at all. It is pretty tricky to get it right.

It's probably the port. My daughter dropped her 5c, which was just enough of a shock to momentarily disconnect the battery and cause micro shorts at the battery connector (this is what the Geniuses told me after looking at the logic board with great magnification). This being the case, the phone would make the charging sound and the apple would come up but disappear when the cable was removed. Power to the unit, but not the battery.

Wish I'd read these comments before doing the guide, first, because I just found lint in my discarded oem part, and then also because since they labelled it as "moderate" in difficulty, I allowed for a hour and it took me three because of the unnecessary removal of the LB. Ifixit still rocks, though.

I personally feel that this guide should not be tagged as being of "moderate" difficulty. I am no shrinking violet, and I have completed dozens of the guides here at ifixit (haven't clicked the "success" button on very many, tho) and I would call this one "Difficult" at the very least. First off, my time is valuable, and I allowed for about an hour to complete this moderately difficult repair, and instead it took me three. Secondly, I would not want an inexperienced noob to think that this was a good place to start fiddling with their iphone. If you haven't say, replaced the volume buttons or headphone cable on a 4 or 4s, when you get to this lightning connector, you could EASILY destroy your replacement connector without that experience, and then that unfortunate ifixer is hosed without a phone for days until a replacement can be ordered and delivered. Third, I honestly do not think that calling a complete and total strip and disassemble of a 5 simply "moderately difficult" is accurate. My 2 cents.
