I'm new here, and couldn't find any references to this specific problem, but this thread appears to be vaguely related. I'm GV 1.3 and just tired to update to 2.0. CWM makes it appear as though the update worked, but when I restart the phone, Settings --> About Phone still shows it's on GV 1.3. I tried the update twice; the first time, I chose "Reboot phone" from the CWM menu after installation, and the second time, I powered down. Same result both time.
Per the instructions, I did NOT wipe data, since I was already on GV 1.3.
