Last week I installed Honeycomb on my Nook Color, and today I found out that B&N released an official Froyo build for it, which I would like to try. I downloaded the update from here, and put the zip on my MicroSD already installed with ClockworkMod Recovery v3.0.1.0.

I started the Nook, formatted Data, System & Boot (in this order), and tried to install nookcolor_1_2_update.zip from the SD. The installer said "Can't open /sdcard/nookcolor_1_2_update.zip (bad)". I coped the file again to make sure it's not related to the unmount of the SD from my PC, and I also opened the file in WinRAR on my PC to verify that it's valid (it is).

What am I missing? I'm very new to Android and try to learn what I can from the web, so sorry if this is a super-newbie question...

I believe that the official 1.2 update will only install on top of an official firmware (1.0, 1.0.1, 1.1.0,) and only with the stock recovery, not ClockworkMod.

You will need to revert your Nook Color to one of these "stock" firmware versions before trying to upgrade to 1.2. Alternatively, there are a few Clockwork Recovery-friendly versions of the 1.2 upgrade that will not require going back to stock first.
