We repaired the broken Galaxy Nexus with a shorted out micro USB port following this simple guide from ifixit. While the guide specifically mentions the Verizon LTE version, it is also applicable to the NTT Docomo GSM version (SC-04D).
The whole thing took about 20 minutes. Here's what we used:
- Samsung Galaxy Nexus charging port flex cable ($9.50 - sku: MBRPSS477)
- Repair Kit Opening Tools for Samsung Cell Phones ($3.50 - sku: MBRTRT175)
- A tiny flat head screw driver
Step 6 mentions to remove the volume rocker ribbon cable. Instead, we pealed off the entire rocker because the attachments are under the board. The glue was tacky enough to re-stick. In Step 7, we did the same thing with the power button.
Between Steps 6 and 7, we also removed the vibrator assembly, which is not shown in the ifixit guide - perhaps it is located differently in the LTE version. It was glued in very well and we need the the small screw driver to pry it out. The vibrator is similar in size and shape to a round watch battery.

We also stopped to take some photos with this microscope. It is surprising that the phone works at all. There is pretty extensive corrosion around the entire assembly. Moisture had entered not only through the open USB port, but also through the speaker grill on the back of the phone. Residual salt was all over the place.
