Thank you so much for posting this teardown!
My Redmi Note 3 Pro developed a charging problem, and this post gave me the basics I needed to replace the usb daughterboard.
The phone was acting weird... When plugged in to a charger, the led indicator did not light up. I tried 7 different chargers and cables including 0.5, 1 and 2amp units. What was strange was that when it was plugged into a dual or quad port charger, any other devices stopped charging immediately. Those with led indicators switched off when it was plugged in.
I hoped it was a short circuit or fault in the usb port, which I learned here was replaceable. So I ordered the part on eBay and replaced it myself at home. All up it cost me $11 to fix my phone, and it is now working as normal again.
I'd like to add that one of the screws holding the speaker assembly is hidden under a tiny sticker, and the assembly and usb daughterboard are both also held in place by glue or double sided tape. Lift carefully and they come off quite easily.
