Broken Micro usb port
How would some one go about fixing the micro usb port that has broken, it has become separated from the motherboard of the device and might have to be soldiered back on
Android-based handheld game console with both touchscreen and gamepad input capabilities, released by Nvidia in July of 2013. Initially dubbed simply "Nvidia Shield," now known as Shield Portable to differentiate it from other Shield products.
The part appears to be the hirose connector ZX62R-AB-5P.

This is not a trivial replacement. At least for me, the solder between the metal shield of the micro USB connector and the PCB has caused some of the circuit tracing of the USB to peal off. I am not sure if this will limit the current carrying capacity of the connector. Also, there is no way to directly solder the pads under the micro USB. You can solder the 5 pins, the 4 PCB punch through points, but not the larger ground pads under the USB connector - the ones that have partially pealed free.
Connecting a cable directly or replacing the motherboard might be the two realistic options.
You can see the broken loose 5 finger pins, the 4 mounting holes, and the two solder down pans in the picture below. If you look at the connector, you can see the two partial copper pads. These are torn loose from the motherboard. Hence the connection can not be reliably reestablished.
Go to nvidia and ask for a replacement motherboard or if they say they can't help open it up and sacrifice an extra long micro USB cable and cut the micro USB plug off the cable and solder the wires attached to the normal USB plug to the motherboard and use a USB pinout to figure out where to solder each wire on the motherboard.
