Can I suggest the following modifications to the step-by-step's:
4 b) Use this command to install via ADB: adb install cwrom.apk or adb install c:\path-to-file\cwrom.apk
[The name of the unzipped file is actually cwrom.apk, not cwr.apk.]
Add a Step 6b -- Turn on WiFi and select your network/enter network password.
[I couldn't get it to Flash unless Wifi was on.]
Add a Step 8b? -- Remove SD card.
[I think we want to boot up into internal here, not Froyo SD card again, right?]
Is Step 9 correct? 9. Power on Nook - this should load you directly into Clockwork Recovery Mode.
[It rebooted back into my usual (customized) Nook environment, not into CWR. Thankfully! Because that's what I wanted to see!! ]
