1. I'm not really sure the difference between rooting or hacking, and I was wondering if anyone could give me some advice on what to use.
2. I also have questions about whether or not I will have the ability to return to the factory OS if I install another?
3. Could I just use an OS off a SD card so when it's not in my NC goes back to factory default?
4. If I install a different OS will I have the ability to read downloaded books through it?
1. No difference, rooting is hacking since it is modifying the OS outside the original software license. What to use? Just rooting the B&N 1.4.3, use Manualnooter. Install new android OS, install CM 10 (CM 10.1 is in beta).
2. Yes. Usually, you can revert back to B&N OS.
3. Yes. You could dual boot from your uSD card, but why? Imho, just dual boot from your NC (emmc), and leave the uSD for your data.
4. Yes, With CM 7 or CM 10, you can download the Nook android app and read and use your B&N content. The exprerience is much different than stock B&N when using the Nook android app. (one reason I dual boot). Just rooting B&N 1.4.3 with Manualnooter, the B&N remains and Manualnooter adds Google Playstore, and some other apps; and a second home.
I hope this helps.
I just used Manualnooter as the previous poster recommended. You can find instructions via this link.
There is a lot of information. Focus on the sections -
Before you begin: and Let's get started:
The link given for WIN32DiskImager does not take you directly to the download. Look for the home button and select it. You will then find the download. I also had a bit of an issue to get it running. Finally did. Your mileage may vary.
Of the choices given, I used - manualnooter-5.08.20.basic.block_updates.zip . I don't know what apps2sd support is nor do I care. Seems like it's just extra I don't want to worry about. So you don't need to worry about kernals.
Important - Watch the video. It is very helpful to watch the video before and during the process. It helps translate the instructions a bit better. Pause and restart the video as you progress through the process.
If you have trouble, post on that forum for help. I just rooted this past weekend so I know it works well. Took all but 15 to 20 min tops. I love it. Much better than going out and wasting money on another tablet like device when I had already spent $250 on the NC when they were first out.
