This past week I purchased a Nook and a 32gb microSDHC card. I played around with the Nook software for about 10 minutes, then decided it was time for CyanogenMod(CM7)! I have this installed on my phone and I really think it is hands down the best custom Android mod. Below are the steps I took to create my bootable SD card for the Nook. Keep in mind these instructions are for Windows users.
- Create a directory on your local machine to download some install files to.
- Download the latest stable version of CM7 and Google Apps from here and save in your new directory.
- Google Apps is really optional, but you will want to install this so you can access Google Market, etc.
- Here are the files I downloaded.
- update-cm-7.0.3-encore-signed.zip
- gapps-gb-20110613-signed.zip
- Do NOT unzip these files.
- Download this SD installer image for CM7 and save in your new directory.
- File can be found here from this page.
- It is size-agnostic so the size of your SD card should not matter.
- Use 7zip to unzip this file to get the image
- Download 7zip if you don't have it.
- Next we need an Image Writer program for Windows. I used win32 Disk Imager and it worked great!
- Insert your SD card into your computer's card reader.
- Open the win32 Disk Imager program
- Select the disk image from Step 3.
- Write the image to your SD card.
- Open your SD card in a File Explorer, copy the zip files there from Step 2.
- Put these files in the root directory, no subfolders.
- SD Card will likely be labeled boot at this point.
- Turn your Nook completely off and insert the SD card.
- The Nook needs to be completely off or the installer will not work.
- If you forget this you may need to start the SD imaging steps over.
- Turn on your Nook and the installer program should boot up and start installing.
- You will see ANDROID in blue text, then scrolling log of install progress with the Linux penguin image.
- Once complete the screen will go blank and power off.
- I have seen some how-to's saying you need to manually power-off. However, for me it did this by it's self.
- Power on your Nook, you will see the ANDROID text again and then the CM7 skateboard image.
- Choose Setup Wizard when prompted.
- Run through the Wizard and setup.
- I chose to skip Account and Network setup in the wizard. After it was complete, I went and setup this on my own.
- CM7 should now be installed.
- If you want your normal Nook software back, simply power off, remove the SD card and power back on.
- There are solutions out there to enable dual boot without removing the SD card. I plan on holding off on this for awhile, but check this out if you want to try it for yourself.
