FAQ


Q1: What is CyanogenMod and why should I use it over stock?

CyanogenMod (CM) is a community-based firmware (or ROM) based on the Android Open Source Project (AOSP). Each new Android release has a corresponding AOSP version, which is used by CM to build ROMs for devices not officially supported by stock Android. Hobbyist developers then port the CM code to yet more devices outside of CM's device list. Thanks to the efforts of verygreen, Nook's lead dev here, both the HD and HD+ are now officially supported by CM. CM 10.1 is based on Android 4.2.x, and has reached general release. CM 10.2 (based on Android 4.3) is beginning its first alpha builds. [Note: These are for eMMC installs only.]

CM offers the full Android experience, and is based on the latest version available. Stock Nook firmware is a much more limited OS, geared to selling Nook wares, and is based on the older Android 4.0 release. CM allows you to do more. However, the flip side to more versatility is more complexity; CM has a higher learning curve.

Q2: What are the different CM installation methods to Nook, and which is best?

There are three install types:

SD - CM is installed to a bootable SD card, leaving the stock Nook ROM intact in internal storage (eMMC). The benefit is that you can easily switch between stock and CM. The drawback is that SD cards aren't designed for running an OS; I/O operations can be problematic, leading to crashes and performance issues. For best results, the consensus is to use the older Sandisk class 2 or 4 cards.

Hybrid - Some elements of CM are installed into Nook's internal storage (eMMC flash), and some elements remain on the SD card. This alleviates the I/O problems of the pure SD install. You still need to boot with a SD card, and the card still needs to be in place to run CM, ie the SD slot can't be used for additional storage.

http://xdaforums.com/showthread.php?t=2097731 (Nook HD development thread)

eMMC - CM is wholly installed into Nook's internal storage (eMMC flash), replacing stock. This is the favored method, as it's the least problem-prone, and frees the SD slot to be used for additional storage. The drawback is that you can't switch between firmwares as easily, and some people are put off by the install's one-way nature. But with a backup of the stock ROM, going back to stock is feasible, albeit more inconvenient.

Q3: Something went wrong, or I have questions. How do I get help?

Search before asking, as whatever problems you run into are likely to have been encountered and solved. For general Android issues, try Google search first. For install specific issues from this guide, browse this thread. If you can't find a solution, then please ask.

Common problems reported:

a) aborted installs - Check downloaded zip files for integrity, as file corruption has been a common problem.

b) can't write to SD card - Check downloads for file corruption. Try a different SD card or a different reader. A simple microSD=>USB adapter tends to work best, as multi-format readers may interfere with the image-writing process.

c) can't boot from SD card - Again, first check downloads for file corruption. Some Nooks are reported to be finicky with booting from SD. Simply try booting several (or many) times, removing & reinserting the card each time. Try with a different SD card. Check the thread for an alternate method of making a boot card, which may help.

The mantra for troubleshooting is to minimize your configuration. Generally, if a problem appears after you've loaded some apps on, revert back to baseline backup to see if the problem still exists. If problem disappears on baseline, then reload apps one-by-one to isolate it. If problem remains in baseline, revert back to stock backup. If problem remains again, return Nook for exchange.

Q4: What are the various Android partitions and their functions?

http://addictivetips.com/mobile/android-partitions-explained-boot-system-recovery-data-cache-misc

Q5: What is ClockworkMod (CWM) and how do I use it?

CWM is a system recovery tool for Android. It is used to backup/restore system images (OS+data), as well as to install ROMs and other software packages outside of Android. It is the go-to utility for all CM ROM uses.

The above guide installs CWM into the Nook; CWM can also be used from a bootable SD card. It is menu-based, and uses the Nook's various buttons to navigate: volume buttons to move highlight bar, Nook 'n' button to select, and power button to go back.

Once installed onto the Nook, CWM can be accessed in three ways:

a) From ROM Manager app. http://play.google.com/store/apps/details?id=com.koushikdutta.rommanager

b) Upon power-up, when either the Nook or the Cyanoboot logo appears, press & hold Power + Nook 'n' buttons for a second or two.

c) Within CM10.1: select Settings > 'About tablet' > 'Build number' (repeatedly tap on it until 'Developer options' appears in the left column). Once Developer options is enabled, select it, enable 'Advanced reboot' to allow reboot to recovery. Then, to access the reboot-to-recovery option, long-press the Power button for the Power menu to appear, select 'reboot', then select 'recovery' at the second menu.

Q6: What is sideloading and how do I use it?

Sideloading means to install apps without using the official Play Store. The option is disabled by default. To enable, go to Settings > 'Security' > Device Administration > enable 'Unknown sources'. For security, enable sideloading only as-needed and disable it afterward.

Once sideloading is enabled, you need to have the app file to be installed. The file will have an '.apk' extension. The file can be on your PC, on a SD card, or within the Nook storage. Navigate to the file with your file manager and tap on it. The file manager will then install it into the Nook. For files on the PC, you'll need to have a file manager that can access shared folders over the network, such as ES File Explorer.

Q7: What is the best [fill-in-the-blank] Android app?

Search for it, eg for file manager: http://google.com/search?q=best+file+manager+for+android
which nets: http://techsupportalert.com/content/best-free-file-manager-android.htm
From there, try a few of the favorites. Repeat for other app categories.

Q8: How do I share files between my PC and the Nook?

You can copy files to/from the Nook with the included Nook cable, which doubles as a charging cable and a data cable. The Nook is accessed as an MTP device, which can be slow and problematic when transferring large files. Files can also be shared via microSD card or a USB device (see below). For large files, this latter is the fastest and most practical method.

Android doesn't presently have built-in filesharing, and it falls to the apps to fill that need. Over wifi, one solution is to install ES File Explorer, which allows connecting to shared folders on your LAN. This works for typical uses like watching movies from a media server. It doesn't work if apps need direct access without ES being the middleman. In that case, you can use ES to copy the resource onto the Nook beforehand.
http://play.google.com/store/apps/details?id=com.estrongs.android.pop

Geek solution: One app that allows direct file access is CIFSManager. However, it is no longer maintained, and the addition of multiuser in Android 4.2 breaks it. CM has implemented a workaround, which is to mount volumes OUTSIDE of /storage (recommended mount point is /mnt/cifs). Second, CIFSManager is very slow when accessing shares of multiple thousands of files. Put another way, there is presently no comprehensive filesharing solution for Android, which will require a native implementation.
http://xdaforums.com/showthread.php?t=756158 (CIFSManager)
http://xdaforums.com/showthread.php?t=2106480 (CIFSManager workaround for CM 10.1)

To share files FROM the Nook, use Samba Filesharing for Android. This sets up a Samba server, and allows PCs to see content on the Nook. Search on 'samba' or 'file sharing' from within the Play Store for other filesharing options.
http://play.google.com/store/apps/details?id=com.funkyfresh.samba

Q9: How do I put a network folder (say, of movies) onto the Nook's home screen?

Using ES File Manager: Swipe left or right to get to the LAN window; tap 'Scan' button to search for LAN shares. Once shares appear, long-press to select the desired share and edit the details if needed. Navigate to the share's desired folder, and select the folder. Tap 'More' button (bottom right); tap 'Add to desktop'.

Q10. How do I connect a USB key to the Nook?

You need a female-to-female USB gender changer, available on eBay and Amazon for about $1. Use it to connect USB key to Nook cable, and connect cable to Nook. Install and run USB Host app (http://nook.rootshell.ru/hd/USBHostSwitcher.apk) to enable USB host mode. [Note: The Quick Setting option to change USB mode is no longer around with the new official CM builds for Nook.] The USB key will automatically be mounted to /storage/USB0.

CM now recognizes FAT32, exFAT, NTFS, and ext4. USB-powered hard drives do not work, as they require more power than the Nook can supply; USB hard drives with external power should work, as do devices connected to a powered USB hub. SD card readers may not work. Some have reported better device compatibility when using an unpowered hub as an intermediary.

When 'USB Host' mode is enabled, Nook cannot charge or be connected to PC. Disable it in the app to regain normal use.
http://www.ebay.com/itm/Type-A-Female-to-F-USB-Gender-Changer-Adapter-Converter-/260535193836?


Q11: How do I use a mouse and/or keyboard with the Nook?

The Nook supports both mouse & keyboard via USB (using same method as above to connect USB keys), or Bluetooth. The Nook should have enough to power both USB mouse & keyboard of the normal variety, using a USB splitter or a hub. Adjust mouse tracking speed in Settings > Language & Input > Pointer speed.

Q12: How do I print from my apps?

Google Cloud Print. http://www.google.com/cloudprint/learn/apps.html

Q13: How do I block ads within browsers and from ad-supported apps?

Google has banned ad blockers from its Play Store, and you'll need to sideload one. The consensus is that AdAway is the best, and is open-source. AdBlock Plus is also available, although ABP now allows ads if vendors pay ABP to let the ads through. Note: Some ad-supported services, such as videos with ads, will FAIL if their ads are blocked. Be aware and disable the blocker as a first step when a service/software doesn't work.

Q14: How do I get Adobe Flash to work in my browser?

Flash is no longer officially supported in Android 4.1 and later, having been obsoleted for HTML5. There are still many web sites that require Flash, however. For these, you can sideload an older Flash version, and use a browser (Firefox or Dolphin) that supports Flash. You may need to enable Flash in the browser's settings.

Get Flash Player from the Adobe site (scroll down to midpage for Android 4.0 archives):
http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

Q15: Do I have to root or unlock the bootloader? I read that you have to do these to use custom ROM.

No. This eMMC install replaces the stock ROM with CM10.1, which comes pre-rooted. The bootloader lock was worked around by verygreen, the lead dev who also ported CM to the Nook HD and HD+.

Q16: What is 'CPU governor' and what do the different settings mean?

A CPU governor regulates the CPU frequency, and is one of several ways to adjust an Android device's performance in a trade-off between battery life and responsiveness. In CM, access the CPU governor via Settings > Performance > Processor. For general use, the default 'Interactive Governor' is considered to be the best balance between battery life and performance.

The below link has descriptions for the many types of governors that exist for Android, not all of which are useful. CM's selections are a practical subset.
http://xdaforums.com/showthread.php?t=1663809

Q17: I've downloaded some files. Where are they located in the Nook?

Run File Manager from the Apps screen. Tap on Bookmarks icon at lower right corner. Internal storage is located in /storage/emulated/0; downloaded files by default will be in /storage/emulated/0/Download. (Download locations can vary by the app, although all user files should be within this area.) Files on the physical SD card are found at /storage/sdcard1. Files on a USB device are located at /storage/usb0.

The bundled File Manager by default runs in Safe mode. To access files outside of the internal user storage, you'll need to raise your access level. Tap on the File Manager's vertical ellipsis (menu) icon, select Settings. Select 'Access Mode' > 'Root Access mode' > ' Remember choice for 10 minutes'.

Q18: I've installed some apps. Where are they located?

System (bundled) apps are located in /system/app. User-installed apps are in /data/app. App data and configuration are normally stored in /storage/emulated/0/Android/. Apps are installed into Nook's internal (eMMC) storage and not the SD card.

Q19: I've backed up my system with CWM into internal storage. Where is the backup located?

The backup is located in /data/media/clockworkmod/backup. System (Nandroid) backups are normally saved to SD card, since backups take up substantial space, and the device's storage capacity is limited. If you want to save backups to internal storage, an easier way is to install the ROM Manager app and use that to manage your backups.

Installing CM11 for Dummies (Updated 7-13-14)

[Edit 7-13-14] This guide is adapted from e.mote's guide for CM10.1/CM10.2 in the first post of this thread. The principle is the same, it just requires newer files.

Summary
Guide for converting the 9" Nook HD+ (Nook HDplus) or 7" Nook HD to full Android, by installing CyanogenMod 11 (CM11 - kitkat) into Nook's internal storage, replacing the stock firmware.

. Download files
. Make bootable SD card
. Back up stock ROM
. Install CM11
. 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 HDplus 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 based on the Dummies guide for installing CM10.1/CM10.2 by e.mote above, and relies on software written by verygreen and others. 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 HDplus.


Have

. A 9" Nook HDplus 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 first card doesn't work.

Make bootable SD card

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

. Format (fat32) any size SD card with SDFormatter (free on web - http://sdcard.org/downloads/formatter_4).

. 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 SD INTO THE NOOK UNTIL TOLD TO DO SO BELOW.


. For Nook HDplus:
Copy
1. NookHDplus-CWM-6046-for-internal-memory-rev0-(07-13-14).zip,
2. cm-11-####-ovation.zip,
and
3. pa_gapps-modular-micro-4.4.2-20140426a-signed.zip

onto boot SD card.


. For Nook HD:
Copy
1. NookHD-CWM-6046-for-internal-memory-rev0-(07-13-14).zip,
2. cm-11-####-hummingbird.zip,
and
3. pa_gapps-modular-micro-4.4.2-20140426a-signed.zip

onto boot SD card.


Back up stock ROM & Install CM 11

. 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 to /external_sd'. 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' > 'choose zip from /external_sd'. Select and install internal CWM, CM11, and Google Apps in that order. Go back to main menu.

. Remove card from slot.

. Select 'reboot'. 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 account 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.

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

. 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.


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_SD'. CWM will back up the whole device onto the SD card. Once done, go back to main menu.


Update to newer CM version

[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.

. 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.

. 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.

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)

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.

. 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.

The above was a collection of my footnotes in getting CM 10.1 installed. There are bound to be errors and shortcomings. Corrections and additions are welcomed.
