[Nook HD, HD+ General] leapinlar:
DO NOT USE THE GUIDE IN THIS FIRST POST FOR CM11. CM11 needs completely different CWM, ROM and gapps files. I have made an updated guide for CM11 in post 7 of this thread below (http://xdaforums.com/showpost.php?p=42406126&postcount=7)

Edit: (1-19-14) This excellent guide was originally written by e.mote. He has moved on to other things and has not been able to keep this guide up to date. He has agreed to let me maintain the guide to keep it current. I will try to keep his clear and concise work his. I will just update as necessary for things that have changed. It has been modified to include CM10.2. (Updated again 07-13-14)

Summary

Guide for converting the 9" Nook HD+ or 7" Nook HD to full Android, by installing CyanogenMod 10.1 or 10.2 (CM10.1 or CM10.2) or into Nook's internal storage, replacing the stock firmware.

. Download files

. Make bootable SD card

. Back up stock ROM

. Install CM10.1 or CM10.2

. Configure CM

. Make baseline backup

. [Update to newer CM version]

Intro

This step-by-step process guides you through the full-Android conversion process, from backing up your stock firmware to installing of CM onto the 9" Nook HD+ or 7" Nook HD. For simplicity and reliability, CM is installed into the Nook's internal storage (emmc). This REPLACES the stock firmware, and you can only go back to stock by restoring it from backup.

The guide assumes no prior Android experience, and tries to avoid as much jargon as possible. It is culled from the extensive guides by leapinlar, and relies on software written by verygreen. Please thank them for their work in making this entire enterprise possible. As well, while this guide doesn't refer to bokbokan's work, please also thank him for his development efforts for the Nook HD and HD+.

Have

. A 9" Nook HD+ or a 7" Nook HD. If it is brand new, you'll need to turn it on and register it with B&N for the 1-year warranty to take effect. Do this before installing CM.

. Micro-SD card of 2GB or larger. A spare card is handy if the 1st card doesn't work.

Make bootable SD card

. Download the correct files for the Nook you have. Files specific to the HD+ are named 'ovation'. Files specific to the HD are named 'hummingbird'.

Note: CM10.1, CM10.2 and CM11 builds are available in the download list. Select the CM10.1.3 stable or the CM10.2.1 stable, NOT a CM11 build.

. Format (fat32) a 2GB or larger SD card with SDFormatter (free on web - http://sdcard.org/downloads/formatter_4). I recommend using a relatively small SD (2 to 8 GB).

. Use partitioning software (Mini-Tool Partition Wizard or EaseUS Partition Manager, both free) to set the first (and only) partition as "active". Don't repartition, just set active. Some versions of Windows will let you set the first partition active without having to use partitioning software.

.Unarchive (extract) the appropriate BOOTFILES .rar file for your device; it'll uncompress to five files.

.Copy the five extracted files to the SD. Copy the file MLO first before the other four files.

.DO NOT INSERT THE PREPARED SD INTO THE NOOK UNTIL TOLD TO DO SO BELOW!

. For Nook HD+:

Copy

1. NookHDplus-CWM-6036-for-internal-memory-rev2-(03-08-14).zip,

2. cm-10.1-####-ovation.zip or cm-10.2-####-ovation.zip,

and

3. gapps-jb-20130812-signed.zip or gapps-jb-20130813-signed.zip

onto boot SD card. Be sure to copy the correct gapps file for CM10.1 or CM10.2.

. For Nook HD:

Copy

1. NookHD-CWM-6036-for-internal-memory-rev2-(03-08-14).zip,

2. cm-10.1-####-hummingbird.zip or cm-10.2-####-hummingbird.zip,

and

3. gapps-jb-20130812-signed.zip or gapps-jb-20130813-signed.zip

onto boot SD card. Be sure to copy the correct gapps file for CM10.1 or CM10.2.

Back up stock ROM & Install CM 10.1 or CM10.2

. Make sure Nook is powered off.

. Partially pull out rubber flap to uncover micro-SD slot at Nook's bottom edge. Insert card into slot until it clicks into place. Restore flap.

. Power up Nook. Nook should boot from card with 'Cyanoboot' logo on-screen. If it boots into stock ROM, power off Nook, remove and reinsert the card, and try again. Some Nooks are finicky and have trouble booting, so try several times. If it still fails, try with a different SD card.

. Once the CWM text menu appears, use volume buttons to move cursor bar, Nook 'n' button to select, and power button to go back.

. Back up the stock ROM: Select 'backup and restore' > 'backup'. CWM will back up the whole device onto the SD card. Once done, go back to main menu.

. Select 'wipe data/factory reset'. Follow prompt to finish action. Go back to main menu.

. Select 'install zip from sdcard' > 'choose zip from sdcard'. Select and install internal CWM, CM10.1 or CM10.2, and Google Apps in that order. Go back to main menu.

. Remove card from slot.

. Select 'reboot system now'. Nook will then boot into CM.

. The boot SD card is no longer needed for normal use, as the Nook can now boot into CWM internal recovery on its own. However, you should keep the bootable CWM sdcard stored away somewhere in case the Nook ever fails to boot. It also contains your backup files. That is why I recommend using a relatively small SD (2 to 8 GB) for the bootable SD. If you want an SD for use with CM, use a different one.

Configure CM

. On first CyanogenMod (CM) login, enter info as needed by Google Apps. You need to have or create a Google acct to access the Play Store (to get apps).

. After getting to the CM Home screen, swipe down from the upper right edge to access Quick Settings panel. From there, select Settings.

. Go to Settings/About tablet/Build number. Tap on that seven times to enable developer options. Go to Settings/Developer Options and select Advanced Reboot which allows rebooting into recovery from the power button.

. Know how to enable sideloading (see FAQ Q6 below).

. Configure CM updates: About tablet > CyanogenMod updates. Set 'Check for updates' and 'Update types' as desired.

. The below link has a tour of CM settings and capabilities. It's geared more toward phones and isn't a primer, but is still an informative read for those new to Android.

. Configure other CM settings as desired. Some setting changes need to be confirmed by selecting a 'Save' or 'Done' on the upper right corner for them to be saved.

. From Home screen, press the center icon in the Dock to access the Apps screen. Select Play Store to get some apps. Limit yourself to the essential core apps for now.

Make baseline backup

A baseline backup is the last resort when things go bad. It's same as a fresh install, but saves on the hassle of installing and configuring the OS and core apps. You can (and should) make subsequent full/incremental backups as you amass more content, but you should always do a baseline backup for every new install.

. Insert a FAT32-formatted SD card (doesn't need to be a bootable card) into Nook's SD slot and make sure it clicks into place.

. In CM, select reboot to recovery (see FAQ Q5 if needed). Reboot Nook.

. Once CWM menu appears, select 'backup and restore' > 'backup to external sdcard'. CWM will back up the whole device onto the SD card. Once done, go back to main menu.

[Update to newer CM version] DO NOT use the update feature described here to update to CM11, the update will not work. Follow the CM11 Guide linked at the beginning of this thread.

[This section isn't part of the install process, but is relevant as new CM builds become available. Because updating has its risks, suggest that you only upgrade when there is a substantive benefit.]

. Check for new CM builds in Settings > About tablet > CyanogenMod updates > Available Updates. Tap 'Refresh' button.

[Note: Both CM10.1.3 Stable and CM10.2.1 Stable builds are available in the download list. For those who want to update to 10.2.1, make sure you also update to Gapps 8/13 or later, which is specifically for 10.2. You'll also want to visit the 'CM 10.2 issues' thread.]

. Tap on an available CM build to see its changelog, to determine if it's worthwhile to update.

. BACK UP your existing set-up in case anything goes wrong (use the above procedure for baseline back-up).

. To update, simply tap to download the available update. You'll then be prompted to allow the auto-update to go ahead.

[Note: CM's internal update may fail and strand you in CWM recovery. The likely cause is the CM put the update file into the wrong location and CWM can't find it. To manually update, in CWM select 'Install zip' > 'Choose zip from sdcard' > browse to 0/cmupdater to find and install the update zip.]

. If new problems arise with an update, you can either restore from an older backup, or do a factory reset in recovery followed by a clean install.
