Mine is the SDCX10/64GB, package says "Assembled in Taiwan". Caution, the third one is a "full-size" SDXC card and not the micro one you're looking for.
While I am still interested in maintaining this thing, I won't be on a computer as much as usual for the next month or so.
hard to tell what might have gone wrong, are you using mfastboot or fastboot?
