[Barnes & Noble Nook Tablet] snooch6923:
Just a little extra to get you on your way:

To make your tablet an "android" tablet, you can either change the device itself, meaning load a custom ROM onto your tablet itself, removing any trace of the original Barnes and Noble Operating System Software, OR, create an SD card upon which you can load and then use to run a custom ROM (i.e., custom android operating system). The benefit of using an SD card ROM is that you do not disturb the original set up of your Nook, do not have to root the device, and therefor your warranty on the device remains intact. When you remove the SD card from your device, you are back to the old Barnes and Noble operating system, undisturbed. If you load a custom ROM onto the device itself, you void the warranty. (Of course, you could always, assuming you did not make a major error, reload the original Barnes and Noble operating system back onto the device at any point, leaving no trace of your shenanigans, and bring it in for warranty service....but there are a lot if "ifs" attached to that.)

So, having said that, if you are a bit hesitant about messing with your device's internal software, until you learn more, I suggested you look for a post on how to make an SD Card ROM. If you make an SD Card ROM, you do not have to root your device or mess with the internal software at all. I use them and thanks to all of the wonderful developers here (tip of the hat to the developers above who were kind enough to respond to you and all the others for their hard work) these work wonderfully!

FYI, this is a great community and very helpful. However, we are all expected to do our homework and should not expect anyone to hold our hand because we are too lazy to read. Don't take offense if you are not hand fed answers. You have to take care also, when you begin, to read entire threads as often issues pop up that may not be addressed in the original post (OP) which usually has a link to the most up too date version of that ROM.

I think I can find a useful thread to get you started but it's late right now and that might take me a few minutes. So, I will try to rememeber to find it tomorrow and post it for you.

Note: I think these days you don't even have to root your device to load a custom ROM directly onto it.....correct me if I am wrong fellow readers. I have no experience with loading internal ROMs, but did root back in the day. So, rooting isn't your biggest issue, it is whether you use an internal (emmc) ROM or an SD Card ROM, and what ROM you choose (each one has it's own benefits...you have to read about them). Do NOT post a question asking which is the best, you will not like the answer you get. They are all great, it's all about what features you want.

Welcome and good luck!

OK, here's what I dug up. Go here:

You can use any SD ROM you like. Once you have this bootabe SD card, "flash" whatever ROM you want onto it. Search for how to flash SD CARD ROM....careful you don't flash it to internal! You will need to read about and learn how to use Clockwork Mod "CWM" to do so, not to be confused with Cyanogen Mod, which you will also need to understand. Cyanogen Mod is the wonderful tool created to get you past the BN boot lock. It's what pops up once you are finished making the Bootable SD Card. It allows you to access all drives of your device and specifically gets you into "recovery=CWM" which you use to flash your ROM. It has an option for SDC BOOT, which lets you boot into your SD card ROM when it is ready!

Good luck!
