sounds exactly right, if you plug it into itunes and its detected then it means that the motherboard is working and that you simply have 0 display. Open the phone up and clear the ports on the motherboard for the display, make sure the gasket around those ports isnt getting caught when you seat the lcd screen ribbon cable, make sure the display port on the motherboard isnt damaged and is clear of debris. Also make sure you arent pinching the lcd ribbon cable on anything when you are closing it up. Finally check your original screen if you still have it, i have seen sometimes on the pentalobe screw posts there are rubber boots that you need to move over to the new screen otherwise it shorts when you close it up. Hope this helps good luck!
Usually when this happens with Keurig's it needs to be put through a scaling cycle. Usually they want you to buy some expensive descaling solution but simple household white vinegar does the trick.

I had the exact same problem with mine as did my neighbor. Its caused from overloading the bullet with tough material. You simply need to warranty the bottom blade or replace it. The Bullet usually comes with a couple different blades. If you use the other blade you probably see different results i would bet. And i would also bet that you smell a rubbering burning smell when you do use the problematic blade right?
You have two mic's on your phone which is why you sound normal on speaker phone. I would take a pin, earring or something small to clear out the small circular holes on the left hand side of your charging port as that is where your mic is located. Alot of my customers either get pocket lint or other small material stuck in those holes and it muffles your audio. If you can confirm that it has been cleaned very well then your next step is to replace the audio/dock ribbon cable on your phone. If you arent comfortable with opening phones you can take it to a repair shop, send it to me or attempt the repair yourself from the video below. iPhone 6 Lightning Connector Assembly Replacement
put your thumb drive into your machine with the power off. press the power button then begin tapping the f12 button until you get into your boot menu. from here use the directional pad to select the usb drive to boot to. From there you will boot into the windows 10 setup.
i agree, try using standard headphones with a mic on it to verify if that works first. next if you have already done a system restore, clean wipe etc. on the phone then it sounds to me like a hardware issue. could have been a drop of water that got into the ear piece, replacing those parts are cheap and fairly easy to do on your own, just requires a little patience as the screws are small
