Factory reset / load to eMMC

[brentashley]

I've played with my UBPorts install by mounting RW and going to town with apt-get, so now that I've learned a thing or two I'd like to revert to the base UBPorts image, maybe even adjust it to fill the available storage.

I can easily download and flash other OSes to SD and boot up on them, but I don't see instructions to install/revert the builtin eMMC.  Any pointers or links?
