CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed.

This rom is for the Nook Tablet 1GB/16GB versions. The device code name is "acclaim".

Prerequisites:

A recovery. To install a recovery when coming from a stock device, you need to prepare a special SD card. Installation instructions can be found here on xda.

Installation:

Android N requires more space on the system partition. To load the Google Apps, it is necessary to repartition the device.

To repartition, flash the recovery partition that can be found here with fastboot:

https://basketbuild.com/filedl/devs...ery-repartition-acclaim-cm14.1-UNOFFICIAL.img

Boot into this recovery and select "Advanced->Repartion Nook Tablet for Android N".

The screen turns black for a minute or so and the repartitioning is happening.

Then select "Advanced->Reboot recovery" to reboot into recovery again.

NOTE: Repartioning will delete all data. BACKUP! It also deletes the legacy internal EMMC partition (which was 1GB big) in case this was not yet done.

NOTE2: If repartitioning fails, please adb into the device and post /tmp/repartition.log to the forum here.

Then you can flash the CM 14.1 images and gapps as usual (e.g. with adb sideload).

Once a version is installed (and all bugs fixed), you will be able to use CM Updater

Settings->About tablet->CyanogenMod updates->Refresh :D

Building:

The CM wiki explains that here: http://wiki.cyanogenmod.org/w/Build_for_acclaim

Returning to stock BN firmware:

If you have installed above rom and the recovery and you really hate it and want to go back to stock, you first have to repartition to come back to the original repartition layout. This is currently not documented.

You may wish to try to flash the original acclaim_update.zip from BN. You have to unzip that file and edit META-INF/com/google/android/updater-script. Drop the first two lines here:

assert(getprop("ro.product.device") == "blaze" ||

getprop("ro.build.product") == "blaze");

Zip the package again. Then go to recovery, flash the zip, wipe, and reboot.

Support:

For any issues encountered, please post into this forum, but add steps to reproduce and dmesg, logcat and audit.log information. If you don't know what this is or how to get them, try to find that out first before posting here.

Thanks:

hashcode, ntemis, kuzma30, fattire, mik_os, and many others that contribute to cyanogenmod and especially this version.

kuzma30 - great kernel job

hashcode - we have reused lots of your work and effort for the various omap devices (esp kindle fire). It is thanks to you mainly that we are now official CM device. Also many thanks for the L bringup help.

mik_os - great touchscreen firmware flasher and other efforts

fattire - for helping us everywhere he can

ntemis - thanks for giving so much energy to this - esp for 4.4 and L I have copied lots of things from you :)

CM community (stargo, david marble, etc.) - thanks for replying to all my questions!

DISCLAIMER:

- update the recovery (see above) if you come from older versions - otherwise you'll see funny error messages when installing zip

- It is possible that you need to wipe your device. I did not do that, but...

- You must flash your own gapps. It can be found somewhere....

Known issues:

- the touchscreen firmware flasher doesn't work on N. Use CM11 to flash it first.

- The system is altogether not really the fastest thing on earth :)
