Buy a Sandisk MicroSD card like this thread suggests to prevent read/write problems due to a slow card. I simply went with a class 4 Sandisk 16gb from Microcenter. Not the fastest loading big movie files, but cheap and works fine.

AVOID 4GB Microsd cards!! One that I had was just a few 10kb short of fitting the CM7 below. >_<

Follow the instructions for Option 1 to root the tablet.

Get the SD CARD VERSION of from here. :-)

CHECK THE MD5 checksum of this download to make it MATCHES THE ONE IN THE THREAD ABOVE! This is to prevent problems if the image isn't the same as the original.

b. Write the image to the Sandisk card above. No need to format it beforehand.

On windows, Option 1 noted using win32diskimager linked works fine.

c. Power the Nook off per instructions after making sure it has sufficient charge!! I'd say at least 25% to be safe even though it takes only two minutes. And boot from card per instructions to root.

d. After rooting, feel free to boot without the card in the nook, then insert.and format the card in the nook.

Now, download the CM7 sd card image. Make sure MD5 checksums match. Write to SD card. It won't fit some 4gb microsd cards because some are a little too small.

4partitions will be created. They'll show up as fat32 for partition resizing later.

Follow the instructions to boot from this CM7 card.

Simplest way to ensure it boots from card is to power off the nook, the plug in the nook usb cable that is plugged into the ac power adapter, or pc. If you don't, it may ignore the card and boot back into the original OS.

3. Optional if you are using a card larger than 4gb.

Once you've booted successfully into cm7, you can power off and eject the card. Take it to a PC and download Easeus Partition manager for free. Launch Easeus and stick the card in. Refresh if needed to make it show up. Select the last partition (one adjacent to any unallocated space on your card) and resize it.to fill up the rest of the card. Apply, eject card and boot the Nook from it. Should still work and you can now use all available space.

4. Now that you're in CM7, go launch NT Hidden Settings app that comes with this. Hacks ->BLock OTA updates to prevent BN from disabling all this fun. You don't need to do it from the Nook OS after this here (but you can if you choose not to do it from cm7).

x-xx Whew. That all is just to get the.cm7 up and running.

5. Start up Google Market or Play app and let it update as needed. (optional, if you desire. Lots of other Android Markets and download sites with the same stuff-eg. getjar.com,.amazon market, etc.-if you don't like setting up a google account)

6. Search the market for QQ. This is the Chinese keyboard, and for english, I like it far better than the default keyboard. You can slide a key up to access.the alternate key. eg. slide up on n to type ?.

7. Search and download Multiling Keyboard along with the Chinese, Japanese keyboard plugins and Handwriting plugin. This is ThE only keyboard I've see for Android that allows pen input of kanji and chinese without driving you nuts, and works for kanji AND hiragana characters AND Japanese varients of Chinese characters like 気　气 氣. Yes, even the iOS can't do this!! :-D (only within Midori can it input Japanese kanji version, but not systemwide).

8. Search and download Adobe Reader, Adobe Flash, ComicReader, MX Player, AEDict, wwwjdic, and EBPocket to start. I like Opera Mini as well.

These basic apps get you up and running on the Japanese dictionary side. Load epwing dictionaries, videos, books, cbz, etc through usb.

9. To view pdf, adobe reader works well because it can also display text only. Zip folders of your jpg book scans, if they're not in pdf yet, and Comic Reader will nicely let you browse tons of ebook scans of texts, magazines,.etc fast! Customizable tap zones let you read right to left books just fine.

Download Xplore to manage your files. TubeMate to download tube videos offline. Winamp to play mp3s.

Firefox is good for option to save pages as pdf.

MX Player just rocks on videos. Fast, subs support, and 1080videos in mp4 at 8000kbps play fine on the Nook 8gb.

---

Whew. Lots of setup for a first week Asian Nook Tablet user to make it useful for the lot, but nice thus far for a useful mobile language study, ecomic and book viewer, and tube downloader.

Will update later on as I get into the Nook more, but works fine and fast with 12gb of book, mp3, mp4, etc content and Chinese/Japanese IO.
