— The installation of ClockworkMod from sdcard did not work.
When I booted the tablet in recovery mode, it was stuck at 3 parrots.
— The next 2 steps (NVFlash and ROM installation) require a Windows driver to be
installed (from SystemUSB.zip). On Windows 7 (Windows7, Win7) the Device panel
looks like this:

— Installed NVFlash, followed the info here:

Using this download ..

When I ran the install from cwm, I got this error:
>> assert failed: getprop(“ro.product.device) == “harmony” || getprop(“ro.build.product”)
I found this comment, applied the fix to the script and re-zipped the folder..
>> I just extracted the META-INFO/com/google/updater-script, removed the first two lines, and replaced it. Then it installed correctly.
Well, the comment above was not exactly right.. it installed without
an error but it never booted.. was stuck at 3 parrots..
— I revisited the page and noticed a 7.1 — with the assert fixed!
