Default [Q] Kindle Fire: Schematic or Service Manual? Failed Micro USB repair.

Good evening everyone!

Have a couple of Kindle Fire's sitting here that I've repaired/replaced a failed USB charge port on and they are not showing any signs of life. Using a breakout cable I have verified pins were soldered correctly and not shorted to each other. I also have one that ripped a couple of pads and think I have it wired correctly. Wondering if there might be any schematics or service manuals floating around for these. Or information/diagrams specifically related to the micro-usb pinouts. I have been searching for the better part of the day today with no luck.

THank you for any help on this.
