What exact commands do you use when flashing?

I'm worried about "fastboot flash userdata userdata.img", because
you're flashing a sparse filesystem onto a partition that might not
have been erased, and because you might be flashing a filesystem of
the wrong size (if can't know if your device has 8GB or 16GB of
storage).

The best approach is "fastboot format userdata" (which is supported on
Galaxy Nexus and Nexus 7). At least, and especially on Nexus 7, I'd
strongly recommend to first erase any partition you flash, and
especially userdata and cache.

Older Nexus devices would implicitly erase the partition before
flashing the new data, but Nexus 7 doesn't do that.
