So I finally got an iPhone 6 Plus, I opened it up to check it out. During the disassembly I found a few QC issues, one...

Why would you believe this is a software issue? If it really is software, just reset all software. More likely, one of your secondary mics have broken, resulting in dysfunctional noise cancellation, in other words, noise addition. Or there is something wrong with the audio IC, which tend to happen on some recent iPhones.

No it does not, the keyboard is completely sealed over with backing foil. https://d3nevzfk7ii3be.cloudfront.net/ig... If you count thermal radiation, it does pass heat out a little, but that’s it.

Basically toast. RAM signals require high precision timing and impedance to work reliably, not to mention there may be multiple vias torn near the pads that probably can’t be reconnected.

The NFC antenna is the top portion of the case itself, check for any screws and contact points around that area.

Clean and pry up the contact fingers very slightly, that’s it.

(1) What components can be at fault in this instance? (2) Usually it’s you opened the screen too hard and tore the screen cable. (3) Could this be a software issue by any chance? (4) It’s your phone, how would we know? (5) Which of the lower two ribbon cable connectors coming from the front side is the one responsible for the home button? (6) One is for display and touch and the other is home button and 3D Touch (7) What is the other lower one responsible for? (8) Above (9) What about the upper one? (10) Above (11) If the home button is faulty, what do I need to replace to enable the Touch ID again? (12) Gone forever, unless you pay Apple for repair. (13) What information can I give you more to help me diagnose the issue? Pictures? Data from software? (14) Keep swapping parts to figure out which one is bad.

Unless you’ve disassembled the antenna part, it’s usually not the antenna. Those things are screwed on and rarely disconnects. You have to identify which RF path has been broken, which is very difficult considering the closed nature of Apple products. In the end it usually leads to somewhere on the board broken, which for a DIYer, is not practical to repair.

That looks like the earpiece speaker mesh. If you don’t install it, dust is going into the phone like crazy. Since repaired phones are not going to have water resistance anyway, the water resistant part actually didn’t matter.

recently got my iphone 8 plus *what* repaired? If air comes out of the sides, get new seals.

You need even more than a new display, you need to use a specific programmer to write screen data, otherwise TrueTone won’t work.

Xs has 4 antennas, while the XR only has 2.

Easy, you are supposed to desolder the battery and the dock flex first, remove the logic board then access the battery.

Look at the CPU heat spreader, it is much thicker than previous models, is it possible that this is some kind of mini flat heat pipe?

Yeah it is just a case ventilation fan, it doesn’t blow any heatsinks directly. Although with the very low TDP of the processor, a case fan with radiator type heat sink should do the job.

It is not possible to access the internals from the back, the back is locked to the case with screws from the inside.

It’s the top bezel itself, as always.

You need to show the back side of the battery, the supplier name is on the back.

No. Basically not related at all.

Zero! Way to go!

As you can see they've already ruined a lot of things, so this is not going back together.
