Installing Apps From Unknown Sources on the Nook HD+

nook HD+ unknown sources

So you went ahead and bought yourself a brand-spanking new nook HD+ tablet from Barnes & Noble while they were on sale for Mother’s Day?  Or maybe you’ve had one kicking around for awhile and now you’re itching to do a little extra with it?  Whatever the case may be, we’ve got you covered.

The latest software update to version 2.1.0 brought with it access to the Google Play Store, opening the door for thousands of new apps to be installed, but that’s not quite enough for most of us.  What if you want to install your own apps from other sources, such as the Amazon App Store or the internet?  Well, out of the box you’re out of luck, but with a little work, we’ll have that nook HD+ tablet of yours allowing installations from Unknown Sources in no time.

We can’t take credit for creating the process, that distinction belongs to the hard working folks over at the XDA Developers Forum.  What we can do however, is break it all down for you into easy to follow, step-by-step instructions.


Disclaimer: We’ve got to get the scary stuff out of the way first.  We didn’t create any of the software or tools referenced below and as such we take no responsibility for their quality.  We take no responsibility for any damage that may be caused to your nook HD+ device while attempting to follow these instructions or through the repeated use of this solution.  Install at your own risk and enjoy.

What exactly are we doing here?: Let’s be clear about the end result of the this procedure.  When we’re done, your nook HD+ tablet will still run the Barnes & Noble flavor of Android that you’ve grown accustomed to.  We’re NOT installing a replacement operating system.  What we’re doing is a slight modification which will allow for the installation of apps from Unknown Sources, which will essentially allow you to install any Android app on the nook HD+ tablet, regardless of where it was acquired from.  That’s all.


I. Requirements

Before we get started, you’ll need to make sure you’ve got a few things handy.

1. A nook HD+ tablet running the stock 2.1.0 software that been configured and authenticated with Barnes & Noble at least once.  [Translation: a nook HD+ tablet that has NOT been previously modified in any way and that you HAVE previously connected and synched with your Barnes & Noble account via the internet.]

2. An 8GB microSD card with adapter that you’re willing to dedicate for use ONLY with your nookHD+ tablet.  [Something like this will do the trick]

3. A Windows 7 computer with an SD card reader and software installed that is capable of decompressing a RAR file and that you’re comfortable using [WinRAR will do the trick]

II. Preparing the microSD card for use

We need to format the microSD card, make it bootable, and place some files on it.

1. Slide the microSD card into the SD adapter.  Slide the SD adapter into your computer’s card reader slot.  Close any dialog boxes that appear.

2. Download and install SD Formatter.

3. Once the installation completes, launch SD Formatter.

4. The application should automatically detect the microSD card in your computer.  In the “Volume Label” field type “nookhdplus”(no quotes) and then click the “Format” button to continue.

SDFormatter

5. Click the “OK” button twice to accept the warning messages that appear about Quick Formatting and removing the microSD card during formatting to begin the process.

6. When the formatting completes, click the “OK” button to finish and then click the “Exit” button to close SDFormatter.

7. Download and install MiniTool Partition Wizard (Home Edition).  When the installation finishes the application should automatically launch.

8. Click on the “nookhdplus” partition to select it.

9. Right-click on the “nookhdplus” partition and select “Modify” -> “Set Active” from the pop-out menu that appears.

nookhd2

10. Click the “Apply” button in the top-left hand corner of the application toolbar to mark the partition as active.

11. Once the operation completes, close MiniTool Partition Wizard (Home Edition) by clicking on the “X” button in the top right-hand corner of the application window.

12. Download the RAR file containing the boot files for the nook HD+ tablet from the XDA Developers forum.  All of the the files available are listed at the bottom of the page.  You want to make sure that you’re downloading a RAR file, that it specifically states that it is for the “NookHDplus” in the filename, and that it specifically states the word “BOOTFILES” in the filename.  At the time of this writing, the correct file is named: “NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13).rar”.

13. UnRAR the file downloaded in step 12 to the root of the microSD card (don’t create any directories on the card, just place the files directly on it).  This procedure will expand the five files necessary for booting onto the microSD card.

14. Download the ZIP file that will enable the installation of apps from Unknown Sources from the XDA Developers forum.  You want to make sure that you’re downloading a ZIP file, that it specifically states that it is for the “NookHDplus” in the filename, and that it specifically states the word “Extras” in the filename.  At the time of this writing, the correct file is named: “NookHD-HDplus-Extras-rev3-(05.06.13).zip”.

15. Copy the ZIP file downloaded in step 14. to the root of the microSD card (don’t create any directories on the card, just place the file directly on it).  NOTE: Do NOT extract the contents of this ZIP file, just copy the single ZIP file, as-is, to the root of the microSD card.

II. Backup

We want to make a backup of your current system before we make any changes, that way, if something goes wrong, you can always restore your nook HD+ tablet to its previous, pre-patched state.

1. Power down the nook HD+ tablet by holding down the power button.  When the “Power Off” dialog box appears, tap the “Yes” button.

2. Eject the microSD card from your PC.

3. Remove the microSD card from the SD adapter.

4. Insert the microSD card into the covered slot in the bottom left-hand corner of the nook HD+ tablet, printed side up.

5. Power up the nook HD+ tablet by holding down the power button.  Clockwork Recovery will boot.

6. Using the volume buttons to navigate, scroll down the available menu options and highlight “Backup and Restore”.

7. Press the “n” button twice to confirm this selection and begin the back up of your current system to the microSD card.  This process could take anywhere from 5-10 minutes to complete.

III. Installation

Finally!  Let’s get that zip file installed!

1. Once the backup completes, press the power button to return up one level to the main menu.

2. Using the volume buttons to navigate, scroll down the available menu options and highlight “Install zip from sdcard”.

3. Press the “n” button twice to confirm this selection.

4. 2. Using the volume buttons to navigate, scroll down the available menu options and highlight “NookHD-HDplus-Extras-rev3-(05.06.13).zip”.

5. Press the “n” button to confirm this selection.

6. Using the volume buttons to navigate, scroll down the available menu options and highlight “Yes – Install NookHD-HDplus-Extras-rev3-(05.06.13).zip”.

7. Press the “n” button to confirm this selection.

8. Once the installation completes, remove the microSD card from the nook HD+ tablet, slide it back into the adapter, and store it in a safe location.  You will need this if you ever need to perform a restore operation.

9. Press the power button to return up one level to the main menu.

10. Press the ‘n’ button twice to reboot the nook HD+ tablet.


That’s it! Once your nook HD+ tablet reboots you should be able to install any app from any source. Give it a test by searching for and installing the Amazon App Store, or feel free to use any other apk file that you might have kicking around.

  • Jacob Roberts

    does this work with hd normal

    • http://www.typographicalera.com/ Typographical Era

      I haven’t personally tested it, but it should. The only difference would be that in Section II, Step #12, you need to make sure that you download the nookHD specific file instead of the nookHDplus one. It’s titled “NookHD-bootable-CWM-6027-for-emmc-stock-BOOTFILES-r3-(02.13.13).rar”. The second file mentioned for download works for both devices as indicated in the filename.

      • Peter Silversmith

        I tried this with NookHD (not+) using rar file as indicated above. However the NookHD does not boot to the SD card -it sees the card, because it offers to format it, but it boots straight to the old op System. Any suggestions how to get around this greatly appreciated. Thank you.

        • http://www.typographicalera.com/ Typographical Era

          Tough to troubleshoot without having access to one of those devices. Have you tried wiping the card completely and starting over with the partitioning and formatting from the very beginning? My first instinct is that if the device is asking to format the card, then something must have gone wrong in the early part of the instructions.

          • Peter Silversmith

            Thanks for follow-up. I carefully re-did everything. I noted in the’ Mini Tool Partition’ tool before exiting one must click ‘General->Apply Changes’ for it to do its thing. Anyway after all that I still cannot get the Nook HD (not+) to boot to the SD card – it just does a regular boot after 1)powering down, 2)putting in the SD card and then 3) power back up. The Nook HD sees the SD card after it power up boots to standard op system because the ‘Devices’ menu shows it mounted and with available space (other than the files I had put on it for this project). Is there some way to make the Nook HD look first to the SD card for booting up?

            Again, I thank you for your generous help.

            Peter

          • http://www.typographicalera.com/ Typographical Era

            Strange. It should always look at the SD card first.

            Just to confirm, after partitioning the card you extracted the contents of “NookHD-bootable-CWM-6027-for-emmc-stock-BOOTFILES-r3-(02.13.13).rar” file to the root of the SD card? There should be 5 files on the SD card: kernel, MLO, ramdisk, u-boot.bin, and uImage.

            Remember, you need the contents of that file, not the one listed in the instructions above, for the HD nook.

          • Peter Silversmith

            Thanks for prompt reply and interest. Yes, confirmed, the 5 files are there from the NookHD (not ‘plus’) indicated download file. I noted on a web search a fellow with a similar problem had success booting using an old 2G SD card instead of 8G card. I tried it with that, and could not get any boot at all – just frozen at “Nook” screen. I’m stuck. Any thoughts or things to try would be greatly appreciated. Thanks again.

            Peter

          • Peter Silversmith

            Searching the web further, I found a person who swore that the Nook would only SD boot from a SanDisk brand SD card, level 6. So I bought one and went through the process with the SanDisk card. And Son of A Gun – the Nook booted from it right off the bat and the rest of the installation was a breeze. So there you are, to boot from Nook on SD card, use SanDisk brand level 6. Why do you think SanDisk can do this and others not? Thanks again.
            Peter

          • http://www.typographicalera.com/ Typographical Era

            Good tip! Great to hear that you got it working. Sorry I disappeared there, been on vacation this week!

          • peter silversmith

            One other thing. I tried to use the Sandisk SD card that just worked on my Nook HD on another Nook HD. The second Nook would NOT boot from the SD card. So I went through the whole process of formatting and preparing the same SD card again. This time it DID boot the Nook and process the change. So the lesson is that this is a one time success for booting a specific Nook – and a new re-format is needed for another Nook. Anyone know why this is? Thank you.

  • Jayson

    I want to thank you so much for these instructions. I know the guys at XDA are brilliant but their instructions were a little over my head. Thank you for simplifying the process and yes, everything worked right the first time.

    • http://www.typographicalera.com/ Typographical Era

      My pleasure. Glad it worked for you!

  • Corey Harville

    Aaron, I have a problem with the steps you listed above. I get all the way to booting up the Nook HD+ with the sd card installed but when I power it on I don’t get the Clockwork Recovery. So I can’t perform the backup from step 6 of Section II and I cant do any of the actions in Section III. Please help!

  • B H

    This worked perfectly for me, or at least I *think* so (still downloading TV Portal). Suggestions:

    1) In your very last step 10, you might confirm that we are really selecting “No” this time.
    2) When I rebooted, there were 2 choices: Home, and something else – can’t remember. I chose Home. Hope that was correct. Don’t know what the other one is, or if I’ll get the choice every time. I did not select “Do this by default” (yet).

    Otherwise, GREAT instructions! Thanks!

    • http://www.typographicalera.com/ Typographical Era

      Thanks B H!

      It’s been a while since I wrote this up. I’ll go back through and take a look at your suggestions. I’m glad that it worked for you!

  • Bruce

    I purchased a Nook HD+ and then a Nook HD because of the ridiculous deals going on. But not being able to sideload apps (Amazon Appstore mainly) was a major negative.

    Using this I was able to enable unknowns sources on the HD+. Believe me I was nervous and waited weeks before trying but everything worked perfect. Even the low cost microSD card I purchased for this worked perfect. Hopefully if I ever need to use it to restore from backup it will again work.

    Now I need to do the HD but my question/concern is the Bootable file (.rar) for the HD. On the same page at XDA Developers Forums just below the .rar for the HD+ it lists a .rar for the HD but it says “for-emmc-stock” and it is dated February 2013. Is this the correct file to use for the HD?

    • http://www.typographicalera.com/ Typographical Era

      Hey Bruce,

      Glad it worked for you! You are correct, that appears to be the latest file for the HD model and would be the one you want to use. I haven’t personally tested it as I don’t have a device to try it on, but it should work. EMMC just stands for Embedded Multimedia Card, which refers to the nook’s internal storage.

      • Bruce

        OK. I need to purchase another microSD card for the HD and then I will give it a go. I am soooo happy I did this, it makes the Nook HD+ so much better. I know some go further and root and/or install a different ROM but I think the stock tablet with the ability to sideload will be perfect for us. Assuming they are compatible I can use all my Amazon apps and continue to get their freebies.

        Thanks again!

    • http://www.typographicalera.com/ Typographical Era

      Hey Bruce, glad that it worked for you! Yes, that appears to be the newest file for the HD and would be the one that you want to use. I haven’t personally tested it as I do not have a device to try it on. EMMC stands for Embedded Multimedia Card, which refers to the nook’s internal storage.

  • Pamela T

    Thank you! I bought the Nook HD+ on sale and needed my paid apps from Amazon Appstore. The directions are very clear, and I now have the Amazon store on my Nook.

    • http://www.typographicalera.com/ Typographical Era

      Good to hear! Glad that it worked out for you.

  • Scott

    I am considering buying a Nook HD+ and installing Jelly Bean (with a N2A chip) on the device. Will these steps still work if I were install it? Thanks.

    • http://www.typographicalera.com/ Typographical Era

      These steps aren’t for replacing the OS or making the device dual boot. They only apply to installing unknown sources on the stock OS.

      • Scott

        Thanks for the quick reply! Any chance that you guys will work on figuring out how to do it after installing Jelly Bean.

        • http://www.typographicalera.com/ Typographical Era

          I’ve toyed with the idea of writing up some instructions for a CyanogenMod installation of Android, but I just haven’t found the time yet.

          • Scott

            Thanks!

  • Bev Merrow

    What happens when BN upgrades the Nook OS? Will our apps from unknown sources suddenly cease operating until the new OS version can be patched?

    • http://www.typographicalera.com/ Typographical Era

      Not sure, but you can always install “NookHD-HDplus-new-OTA-hosts-block-rev2-(03.29.13).zip” to block OTA updates if you’re concerned. Any update shouldn’t affect anything you’ve already installed, but it could affect your ability to install new things.

      • Bev Merrow

        Thanks. I don’t think BN makes that many upgrades and each have added valuable new features. Don’t think I want to block upgrades. Guess I will just have to wait and see when it happens.

  • Bruce

    A couple quick questions. I thought I had to dedicate the microSD to this mod. Meaning I put the files on it, use it to make the mod and do the backup and then remove it to use the Nook. I see someone saying they keep the card in and other than a message they have to clear each time at start up they can use it to store other files (movies etc.).

    I specifically bought two 8GB cards to use for this mod because I didn’t want to “waste” the 32GB I had but now I wonder if I could do it this way? Any idea? Also thought I couldn’t use one card for both the HD+ and HD since there are two different CWM files. Any way I could use one card for both?

    • http://www.typographicalera.com/ Typographical Era

      You could. The idea behind the way these instructions are written is for you to put the card somewhere safe in case something goes wrong some day down the line rather than use it and risk accidentally deleting or corrupting the backup you’ve made of the default system.

      • Bruce

        Regarding using one card for both the HD/HD+ I would first have to get the HD+ CWM bootfile off of it first before adding the HD CWM, right? Or can I have both bootfiles and it will use the correct one?

        Talking about this further on another site someone said just to reformat the card and use it for whatever. But then like you said I lose the backup created. Is it possible to move the backup off the card to my computer? Then it is there for safekeeping and can always be put back on a card if I need to use it.

        • http://www.typographicalera.com/ Typographical Era

          Absolutely you could copy the backup off the card and reformat it. Here’s the thing: the card, as it is right now, is all configured and ready to go in order to restore the backup. Let’s say the nook crashes a year from now…are you going to remember how to format a new card, find and put the right files on it, find this post even? This is all written and designed so that when you’re all done you have everything you need safely tucked away, ready to go, in case of an emergency. No work at all, just pop it in and restore.

          That said, it plays to your level of comfort with technology and how much you’re willing to spend for peace of mind. To me, those cards are pretty cheap nowadays and having a backup that’s ready to boot is reassuring. If you’re a tech-saavy person and you’re not worried in the least about it, I’d say reformat it.

          We’re primarily a book blog here, so I like to err on the side of safety when designing these instructions. :)

  • BbBob

    Man, you are beautiful! I got a new Nook HD+ 32GB just yesterday and am today downloading some apps from Amazon Appstore, those unavailable at Google Play Store. I (and needless to say many others) appreciated very much your step-by-step, clearly detailed, and easy to follow instructions. Your thoughtfulness to have included the backup program is hot chocolate! Millions of thanks!! Next, I will have to find a way to watch Prime Instant Videos on my Nook ;)

    • http://www.typographicalera.com/ Typographical Era

      Glad it worked for you!

  • Lee Moore

    Thank you so much for your help. This worked flawlessly. I used a 16GB SF cause that’s the only size size I had on hand besides a 1GB which would have been too small.

    • http://www.typographicalera.com/ Typographical Era

      Excellent! Glad you were successful!

  • shanec25

    This has got to be the most direct and to the point tutorial that I have come across and It helped out alot. Was up and running on my first try with my Nook HD and everything works flawlessly. Thank you so much for taking the time to do this and sharing It for those of us whom have greatly benefited from It.

    Your directions were perfectly clear, and everything went perfectly. I ran into problems when I loaded from apps with on Amazon account, and then attempted to use another I had apps on. A re-install didn’t work, and I read on XDA that it doesn’t. Am I forced to do a factory reset, and thus lose my current set-up?

    • http://www.typographicalera.com/ Typographical Era

      Not sure, I’ve never encountered that specific issue!

  • James Screech

    Good clear instructions, thank you.

    Could we have similar for a full root?

    • http://www.typographicalera.com/ Typographical Era

      I’d love to at some point, but unfortunately I need another device to work with before that can happen.

  • Jim Stanley

    Thanks for this post, I just have one follow-up question:

    Will this give Orbot, or other apps that require “Superuser Access” their access?

  • Jim Stanley

    Thanks for the post, I just had a few follow-up questions:

    Will this process provide apps with “Superuser Access”? (required for Orbot)

    If not, is there any method to accomplish this other than rooting that you are aware of?

    If I must root, is their any guide you can link me to?

    Thanks for your time.

    • http://www.typographicalera.com/ Typographical Era

      By Superuser Access, I assume you mean root level access, which will give apps access to the /system directory and other areas that you generally can’t see or access.

      You can easily allow this on the device by downloading “NookHD-HDplus-Universal-Root-rev2-(02.02.13).zip” from XDA page linked above and then follow the install instructions written above. I’m not familiar with Orbot, but if it needs system level access, that install should do the trick!

      Just one word of caution: whatever apps you install that take advantage of that level of access, be sure that you configure them properly.

  • Brian

    Awesome, installation went perfectly :-) I now have Amazon app store and Humble Bundle apk installed (to access & install all my Humble apps). Thank you for all your work on this article, my Nook HD+ has new life.

  • Bill Calder

    Many thanks for this clear guide. Downloading from Amazon Store on my Nook HD now.

    Nook update to 2.1.1. The boot does not work anymore – right after I did a factory reinstall. Any other options?

    • http://www.typographicalera.com/ Typographical Era

      What happens?

      • connie

        When I booted up with the sd card in place, the screen went black. It was a bit of a problem shutting down, but I could when I removed the sd card with the mod. I went through all the steps reformatting the card, and found the only thing that had changed was the 2.1.1 update, when it still the screen still went black. I guess if there is a way to revert to 2.1.0 it might work, but I don’t know how.

    Thanks Aaron for the guide, this is very clear and work after first attempt. I was able to install an app which I was not able to previously. I read the instructions 5 times before I actually do it, it is as clear as it can get, first class “how to” in my own opinion. You are the best!

        Add me to that list, not sure why its happening either because I had it rooted before and had to reset it and when I tried to flash it just not take for some odd reason to my nook HD+. ;(

    • rutherford

      I am an advanced klutz when it comes to this kind of stuff. Not taking anything away from this guide as it is a valuable one and obviously works for a lot of folks but if you’re like me and need a visual demonstration (done slowly) on youtube type in “root your Nook HD and HD+ by Jonathan Yang” it may be to your liking. It worked for me and now I have both the stock B&N Nook that my Nook HD+ came with and all the advantages of a rooted tablet…the best of both worlds so to speak.

  • android fan

    installed on 2.10 nook firmware & i’s working fine,this week nook released 2.11 update so i updated & still works fine BUT the important question now is will this super useful mod work on tablets that already come installed with latest nook firmware ?

  • android fan

    i can confirm i just received a nook HD+ tablet with 2.1.1 update & this mod worked on it fine but i did use the latest file instead from XDA the latest file called: NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13)

  • Peter Carrillo

    I can’t find the extras download on XDA forum. I found the first file but it was updated. I can’t do anything else until I find the extra file. Any suggestions?

    • http://www.typographicalera.com/ Typographical Era

      Looks like they updated the instructions…check section 3:

      3. Enabling Unknown Sources – (rev0 – 09/08/2013)

      The earlier Extras zip is not really necessary any more. I have replaced it with a stand alone Enable Unknown Sources zip and attached it below. You will need to have booted and set up stock before flashing this zip. But you do not need to be rooted.

      And I now have a version of the Extras zip (which includes enabling Unknown Sources) for stock on SD by verygreen. Get it here (This version is only for users running stock on an SD.)

  • Alan OBrien

    Tried this twice unfortunately it does not work with system update 2.1.1 the process completes fine but when you try to sideload you get the error message “nook cannot read this file”. Also tried the ADB push route but that failed as it would not recognise the Nook serial number. Still looking for a method that acutually works.

    Please help! Just bought 32gb HD+ because saw this earlier & thought I could get amazon apps I bought too. Amazon prime video too but guess another issue. Trying to do in 2 weeks I have to return back to store if fail because otherwise wouldn’t have gotten this. Your instructions are excellent, well laid out & we got through everything fine until step 13 & 15? What are we missing? We tried copying files, extracting files, using wizard on files but still they always show as no files found when loading onto nook? We’re total noobs obviously. But really wanted this first tablet purchase to work as family tablet & also for toddler amazon prime Daniel Tiger & Mr Rogers Neighborhood. Would love any advice!

      Does it boot to Clockwork Recovery when you have the microSD card in? Some of the newer models have trouble booting from the microSD…more info here:

        It does, but when we go to installation trying to zip file from sd card it always says file not found. I think we’re doing steps 13 & 15 wrong because we’re not actually sure on how to unRAR the files selected? Those parts of the instructions aren’t clear for us on what actually to hit & do it? We tried extract & copy & paste the .tmp , .system, etc files. But when we put sd card into the Nook & select zip file from sd card it shows all those actual file names & not just the nookhdplus name like instructions say it should show. So then even when we try to zip .temp or .system files seperately it just keeps saying file not found? That’s where we’re unclear on how to unRAR the files steps 13 & 15. Really excellent instructions though & see many people in comments have succeeded we’re just truly not computer savvy, lol. Thanks again for any clearer help! :-)

          Install this on your computer to unrar:

          http://www.rarlab.com/download.htm

          Unraring shoud give you five files. Those five files along with the zip file (don’t unzip it, put it on there as a .zip) need to go on the MicroSD card.

          • edread

            We’re getting 5 files but we’re not getting them to sd card correctly. The 5 file folders we get are .., data, meta-inf, system & temp. Not getting zip file at all. But your instructions make perfect sense above this part so don’t get what we’re missing. Why no zip file? Is there a button to push on winrar-x64-501.exe. That we’re supposed to push? Sorry being such a noob! :-)

          • http://www.typographicalera.com/ Typographical Era

            The zip you want to download is this one:

            NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13).zip

            plop it on the MicroSD card as-is…don’t unzip it.

            In addition, if you unRar’ed the other files correctly your card should have all the files in the attached picture.

          • edread

            Perfect, what we did & looking right now except suddenly now nook HD+ won’t go into clockwork recovery. Did it fine the other day! Just wants to factory reset. Once we even tried that, reregistered it & relogged in. Still won’t open into clockwork recovery. I’m going insane as I’m sure you are too with my crazy questions. Going to keep trying but if have hint, I’ll take it. I’m determined to like this tablet!

          • http://www.typographicalera.com/ Typographical Era

            Two things…

            1. With all the trouble you’re having you might want to start fresh from the beginning and reformat the card…

            2. Double check that you have the right BOOTFILES for your device. There are different zips for the HD and the HD Plus.

          • edread

            Thank you, appreciated

            I can’t get it to Clockwork reboot and I followed to steps perfectly. PLEASE HELP.

    Mine loads CWM and allows me to install zip files, but none of the zip files I’m trying are allowing me to sideload. I have a 2.1.1. Anyone know which files to use? I’ve tried “NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13).zip”, “NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13).rar”, and “NookHDplus-verygreen-New-SD-fix-stock-to-use-New-SD-Media-rev0-(06.01.13).zip”

  • BiGg RiE

    This worked perfectly for me, I used:
    NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13).zip = Flashable Zip
    &
    NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13).rar = Boot Files extracted to root of SD card

    Followed the instructions to the T and everything came out fine, it did take a few times to get the nook to boot, I’d almost given up but my Son (9yrs old and his first mod/hack), decided to give it one last go, and CWM booted and I was able to back up and then flash the zip.

    Nook HD+ w/2.1.1 FW

    Right after I did this and confrmed it worked, as I was installing apps from my google drive app, the update to 2.2.0 downloaded and installed.

    I can confirm that this mod carries over to the new 2.2.0 firmware upgrade… not sure if it will work from scratch on the 2.2.0 fw but I have another Nook to do this on (my daughter’s, this one is my son’s) and if the 2.2.0 update has downloaded on hers already then I guess i will be giving it a shot. Then again I haven’t allowed her access to the internet yet so, I’ll just flash it, and then connect.

    Cheers for the awesome write up!

    Would there be a way to do this procedure without a computer?

      Not that I’m aware of, sorry.

    i can’t find the file NookHD-HDplus-Extras-rev3-(05.06.13).zip what i have to do?

  • J.h. Montgomery

    So: 1. There is no more extras file. I searched on the forum a little bit and it got replaced with a file called NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13).zip. 2. I did everything here. Tried 3 different ways, and each one resulted in my Nook getting reformatted. Has anyone else reported this?

  • claude martin

    First time poster, so bare with me… After several unsuccessfully attempts to install the files that would allow me to load apps from my Amazon app store, I discovered my error and I wanted to pass it along. The .zip file should be loaded directly to the sd card from the download file folder, not as I had attempted, downloading using WinRAR which unpacked the files. After correcting that, I found the file on my sd card, loaded it on the nook and everything went as you described. I’ve downloaded the Amazon app store and have full access! Thank you for your excellent instructions.

    Regards,
    Claude Martin

      Glad it worked for you, Claude! Enjoy!

      I am trying to insrall the “unknown sources” zip to my Nook HD. I have followed instructions to create the bootable sd card so I won’t have to root my new HD (STILL UNDER WARRANTY), and cannot get the HD to boot from the sd card. Anyone have a trick to do this? I have restarted the HD 10-15 times in a row, but it just will not boot from sd. I have checked to be sure I have the correct bootfiles and my sd is formatted fat32. Help! I really want to gain access to the apps I loaded on my kindle.

      I am replying to my own post to say I did it! The important step I forgot was to download and use Mini-Tool Partition Wizard to set the partition active. As soon as I did that, inserted the card in my HD and booted, it went good. I installed the “Unknown Sources” zip and was able to reboot to stock (modified) Nook HD and install Amazon App Store, then install apps I had purchased through my Amazon account for my old Kindle. Thanks to the developers and tinkerers who work on these projects to help us all enjoy our various Android-based tablets despite manufacturers efforts to the contrary.

        Hi Larry. Sorry I wasn’t able to reply to you sooner, but I’m glad you worked it out. Enjoy!

  • Shellie

    These steps were perfect! THANK YOU so much! The only thing I needed was the updated zip file name from step 14. I scrolled down the posts here and luckily someone had found the most updated one and posted it.

    So as of today, the ZIP file name for step 14 is:
    NookHD-HDplus-stock-enable-Unknown-Sources-rev0-(09.08.13).zip
    Funny, the app I needed as Amazon App Store and it installed successfully.
    Thanks again!

  • Murray

    Would this work with the Nook HD (not plus), software version 2.2.0.
    Please and Thanks.

    • http://www.typographicalera.com/ Typographical Era

      Yes. Just make sure you download the files that are labelled for the nook hd instead of the nook hd+ and you should be fine.

  • Murray

    Does this work with the 2.2.0 software version? Nook HD.
    I have tried to do it, followed the instructions carefully but it doesn’t seem to have worked, is this because of the software version or perhaps mistake on my part. Thanks!

    • http://www.typographicalera.com/ Typographical Era

      Yes. Just make sure you download the files that are labelled for the nook hd instead of the nook hd+.

  • Ethan Pierce

    There is no such file as “NookHD-HDplus-Extras-rev3-(05.06.13).zip”

    • http://www.typographicalera.com/ Typographical Era

      Looks like they updated the instructions…check section 3:

      3. Enabling Unknown Sources – (rev0 – 09/08/2013)

      The earlier Extras zip is not really necessary any more. I have replaced it
      with a stand alone Enable Unknown Sources zip and attached it below.
      You will need to have booted and set up stock before flashing this zip.
      But you do not need to be rooted.

      And I now have a version of the Extras zip (which includes enabling Unknown Sources) for stock on SD by verygreen. Get it here (This version is only for users running stock on
      an SD.)

    It just wouldn’t boot with the SD?
