[Nook Color Android Development] faceman66:
In an effort to completely document the "Going to CM7 and Coming Back from CM7" experience for myself and my fellow rooters, I have compiled the following diary of install. Please let me know if there are missing steps or extraneous steps that can be removed. Remember please that I am trying to COMPLETELY document the process (at least as much as pertains directly to CM7) and the audience is for everyone, even real noobs who you know will be trying this and crying about some dumb mistake. Thanks for your feedback.

Before beginning:

1. Booted into Recovery

2. Created new nand backup

3. Removed and stored MAIN sd

Using a new and different sd:

1. created 4gb CWR_ext4_0.1 bootable SD [Followed process here: http://xdaforums.com/showthread.php?t=959240]

2. moved flashable zip of CM7 to SD [edit: now using latest nightly found here: http://forum.cyanogenmod.com/forum/228-nightly-builds/]

3. moved latest gapps to SD [Found here: http://wiki.cyanogenmod.com/index.php?title=Latest_Version/Google_Apps

4. moved latest Froyo/CM7 overclock kernel to SD [Found here: http://xdaforums.com/showthread.php?t=925451]

4. insert into NC

15. WOOT! CM7 Home Screen!

16. Open Apps --> Settings --> CyanogenMod Settings --> Lockscreen --> Style Options --> Lockscreen style --> change to Sliding Tab (this is because the Rotary wheel isn't sized right yet and is real hard to use currently)

20. Open and tested each user app (some worked, some didn't - but it's early)
