   That's not a real firmware version number.  Copy+paste is your
friend.  (Or take more care.)

   What, exactly, did you download?  What, exactly, did you try to load
into your modem+router?  Did you read the instructions in the Release
Notes file?

   True.  But it might help if you started with an appropriate firmware
kit.

   The D7000[v1] and D7000v2 are two different devices, which use
different firmware.  "(v 1.0.70" seems to resemble "V1.0.1.70", which is
a D7000[v1] firmware version, not a D7000v2 firmware version.  Note that
the firmware image file for a D7000[v1] is a ".img" file, and for a
D7000v2 it's a ".chk" file.  Different.
