Hacking a NookColor

A few months ago, I picked up a NookColor.   Being a geek, I immediately hacked it to run an unrestricted version of the Android operating system, allowing me access to the Google App market and, interestingly, the Kindle app.  Yes, I run the Kindle app on my Nook.   I also run Netflix, Dropbox, Evernote, and any other app I want.

It is, after all, my Nook.

This weekend, I’m visiting my parents, who, coincidentally, also have a new NookColor and want to be done with the slow, restricted version of the operating system that came with it.

Last night, I hacked their Nook.    The site I use for the files doesn’t have instructions that work for me.   It’s close, but since we’re not talking about horseshoes or hand grenades, close isn’t good enough.  “Close” doesn’t get me a working Android tablet out of a $150 book reader.

So, instead of having to remember what I do every time someone asks me to help them root their Nook, I’m posting my system here.

If you want to get the biggest tablet-bang for you buck, here’s now to hack a Nook color into an unrestricted Android tablet, without voiding the warranty.

In addition to the Nook, you’ll need to get a microSD memory card, that’s at least a class 4.  The classes are a measure of speed and are identified by a number in a circle on the side of the card.  Don’t bother going with less than a 16GB card, and 32GB is better.  If you don’t have one already, look for a card that includes and SD card adapter, because it’s easier to find a computer with a reader for those.

You will need to install Win32 Disk Imager, to prepare the memory card correctly.   Most guides recommend WinImage, but I’ve never gotten that to work.

First, download the core memory card files.  Use WinRar or something similar to extract the image file.

Insert the memory card in your computer.   Make sure the computer is reading the card size as close to what the size you are expecting.  If it’s not, you may have to reformat the card.

Fire up Win32 Disk Imager.   Browse the the extracted image file, select your SD card drive letter and click “Write”.   If it pops up anywin32 disk imager warning messages, confirm them and let it run.   Everything it wants to do is a good thing to have happen.

Eject the card, then reinsert it.

Next, download the latest nightly build of the CyanogenMod.  The file name will be something similar to cm_encore_full-253.zip.   This can be the problem step.   The first time I did this, the nightly build was broken.  I waited a night and tried again, but that version had a bug with the wifi.  You may have to try a couple of different builds to get it to work.    After you have the file, copy it, unchanged and unextracted to you memory card.

Now, take the microSD card out of your computer and stick that bad boy in your Nook.   There’s a little door on the back bottom corner.   Turn the Nook on and wait.   It will take a few minutes for everything to set itself up, so be patient.    You will see lots of text you probably won’t understand.   Watch it and pretend to understand if anyone is paying attention.   It’s an instant boost to your geek cred.

When it’s done, it will power off.   Turn it on, and go to Settings/Wireless Networks.   Set up a wifi connection, then turn the thing off and put the card back in your computer.

Do you have a gmail account?  If not, get one.   You can’t get into the Google Apps Market without one.

Now we’re going to install the Google Apps Market App.   This is what will let you install more apps.

Go here, scroll to the bottom and download the CyanogenMod 7 version of Google Apps.   Copy it to your memory card, the pop it out, stick it back in the Nook and fire it up.

When the Nook finishes loading, press and hold the power button until you get the power off menu.   Select “reboot”, then “recovery”.  This will reboot the Nook, installing the Google Apps file you’ve got on the memory card.

When it’s done, you’ll be walked through a wizard to set up you Apps Market account and a bunch of default settings.   After that, you’ll have a complete, unrestricted Android tablet.

The best part is that, since we’re doing all of this on the memory card, it’s not voiding the warranty.   If there’s a warranty problem, just pop out the memory card and send it in.

What apps should you get?   I start with the Nook app, then get the Kindle app, and the Overdrive app.    The Overdrive app is what lets me get books from the library system, and you won’t be able to get the desktop software to read this tablet as a Nook any more.

From there, the sky’s the limit.  This is now a full computer.    You even have the option of turning on the built-in, but disabled-by-default bluetooth, which will let you use an external keyboard.

Beats a netbook by a mile.

    1. Very interesting. I have always been nervous about hacking any of my stuff. Voiding the warranty scares me. Plus I worry about wrecking something and not being able to fix it. Glad ti worked out for you though.

    2. That is just awesome. I’m with Miss T though. I always feel like I know just enough about computers and files to get in trouble. This is something that I would like to learn but I just don’t know if I want to make a $100+ gamble doing it. Very cool though!

    3. This is awesome. If I had one I would ship my Nook to you and have you rewire it for me. Haha, you should make a side business out of it! Hope you had a great Thanksgiving!

    4. Thanks Jason, bookmarking this in case I need to hack my own device.

    5. An important note about this style of hack: it doesn’t void the warranty. The entire hack is done on the memory card. If you don’t like it, just pop out the card and the hack goes away. If you need to send it in, same deal.

    6. I thought very seriously about doing this actually. Still might down the road. The nook is a little bit more kid sized and would make a great travel companion for the kids. Next big trip isn’t for about a year or so though, so got time to save up.

    7. Dang, I might have to get a new memory card and a card reader!

      I’ve wanted to do this but wasn’t sure of the steps. If it’s all on the card then I can’t screw it all up too bad, can I?

      Also, can this be done on a Mac or do you need a Windows computer to get the files?

      • It’s all on the card. You can’t screw up anything. 🙂

        The only thing you’d need to find is a working disk imaging program for the Mac. I’m not a Mac user, so I don’t know what that would be.

    8. Your instruction worked flawlessly on the first try!


    9. Im incredibly tempted to try this…but i have a few questions

      So it basically runs it as a tablet from the information on the sd card?


      As long as i install the nook app can i still get any suscriptions i have?

    10. One question… is this hack possible on the Nook op sys without using the Media card?

    11. One last question…will it make it 3g compatable? Im not even sure if thats a feature of android tablets.

      Thanks again

      • That’s one I can’t answer. There are 3g nooks, but I don’t have one.

        • Last question…so, I followed the instructions and first build I tried didn’t work. Second build I tried did, but nearly EVERYTHING wants to force close or starts up really slow. Should I start over and try another build?
