[Nook Color Android Development] pndo1:
Hi fellow nookers,

My friend (@ikingblack on XDA) has released 2 guides as of now, and unfortunately, his guides are a little misleading, and has you flashing packages left and right. Hopefully, this time I will try to get it right. I am not trying to be rude, just trying to point out that his guides are a little scant and incomplete. And please feel free to leave bad comments so I can improve it.

All right. Enough of that yucky stuff. Here's the Guide:

Requirements:

1. Rooted Nook Color with ClockworkMod Recovery (3.0.0.10 or later)

2. An SDCard that is bigger than 200 MB.

3. A Browser on the Nook that has the option of downloading to the SDCard.

4. Internet Access on the Nook is not required (NO).

5. A flashable ROM for the Nook on your SDCard

6. A ClockworkMod SDCard, which is optional but makes it easier (Especially Step 8). (search around the forums, will post link later) Please keep in mind that you have to take the SDCard out whenever you want to boot the Nook Software, and not ClockworkMod. Also, when I say boot into ClockworkMod in the guide, then you can just insert the SDCard and reboot.

Notice: Whenever I say download a certain file, it means download it to your SDCard. It does not matter how you do it, just get it on there. You can download it on your Nook, or download it on your computer and put it on the SDCard. It really doesn't matter.

Step 1.

Make sure you have a valid backup that is current. If not, make one, either through ROM Manager or ClockworkMod.

Step 2. First, download the preparation dual boot file. If you have dual booted before, and haven't removed it, then skip this download. Download Here.Then download the stock Nook ROM flashable zip, I recommend this one: Download. It is the latest version and keeps ClockworkMod. Keep in mind that the package has to keep ClockworkMod. Then download the root file if you want root: Download. Then the Second root file: Download. Finally, download the dual boot file: Download. Please remember the file names so you know what to flash. If you want, you can rename them.

Step 3. Boot into ClockworkMod, (If you have an SDCard with ClockworkMod on it, insert it and reboot.) and go into "Mounts and Storage" (Use the Volume Buttons to scroll and the n/home button to select). Then select Format /System, and select yes. Then format Data.

Step 4. Press the Power button to go back, and select "Install zip from SDCard". Then select the second option or something and browse for the first downloaded, or the preparation dual boot file, called prep-dualboot-0.1.zip, and select "Yes". After it is done, repeat Step 4 except with the second downloaded file, or the Stock Nook OS file, called update-nc-stock-1.2-keepcwm-signed.zip.

Step 5. If you have the ClockworkMod SDCard, take it out now. Then reboot the device by going back (can be achieved by pressing power) and selecting "Reboot Device Now.

Step 6. It should boot into the Stock Nook OS. Follow the setup procedure. Keep in mind that you need WiFi.

Step 7. If you want root, then reboot into ClockworkMod. If you can't, or don't know how, then use the 8 failed boots method. 8 failed boots means boot it up, and before it reaches the logo, (The pulsing B&N Nook Color) shut it off holding the power button. Even though this takes long, I don't know of anything else.

Step 7 for ClockworkMod SDCard users: Just insert your ClockworkMod SD, and reboot! Simple.

Step 8. Flash the second file, or the root file called ManualNooter-4-4-278.zip. Then Flash the second root file, called apk-enabler-1-1a-signed.zip. Then if there is anything else that you need to flash, then flash it. Please keep in mind that as of now Dalingrin's kernel should not work with it unless he releases an update. I haven't checked this, so please correct me if needed. After you are done, flash the last package, the dual booter, called eclair-dualbootv2.zip or something. Then reboot and hold the home button when it says multiuboot loading. It should load the nook os.

Step 9. Then download Rom Manager, from here: Download, and then install it. Flash ClockworkMod by tapping the first button, and selecting Nook Color (not Nook Color (old)). Then reboot into recovery.

Step 9 for ClockworkMod SDCard users: This time, you will have to flash ClockworkMod onto your device. Just follow normal Step 10.5 (Not for

ClockworkMod SDCard users).

Step 10. Reboot into ClockworkMod again, via Rom Manager. When it is in ClockworkMod, then insert the SDCard where you have the backup and the Custom ROM that you want to dual boot. Once you have inserted it, go into Mounts and Storage, and select Mount SDCard. If the option says unmount SDCard, then you are good to go. Then flash the ROM that you want dualbooting, and any other zip that you want on the non-stock or custom ROM. After you are done, then go back, and select backup and restore. Select Advanced Restore and select your latest backup. Then select restore data. Once it is done, then you can reboot and it should reboot into your custom ROM (if you didn't hold the home button on boot).

You are now done! When you want to boot into the Nook OS, hold the home button when you power on and the nook says multiuboot loading. If you want to boot up your custom ROM, than don't hold the home button. You can also now get into ClockworkMod by holding both volume buttons when it says multiuboot loading. Please do not hesitate to post with complaints, improvements or the like. Thanks! I want to improve this and my knowledge in every way I can.

EDIT - I updated the guide on 4/29/11, and I might have made some errors. Post if you find any!
