[ROM] CyanogenMod 11 Nightly Builds for Nook Color

The NookieDevs are pleased to announce CyanogenMod 11 nightly builds for the Nook Color!

These experimental builds contain the latest changes to CyanogenMod and to hardware support for the Nook Color. As the name suggests, new builds are made and posted (roughly) every day; these builds are fully automatic, with no testing done before posting. As CyanogenMod 11 is still under active development, regressions and general breakage are to be expected in nightly builds!

Highlights:

• Linux kernel 3.0.101, plus hardware support from TI OmapZoom's android-omap3-3.0 branch and board support forward-ported from BN kernel releases.
• All of the features of CyanogenMod 11, based on Android 4.4. For Nook Color, this brings a reduced memory footprint, which leads to a better all-around user experience.
• Full 2D and 3D graphics acceleration using both the GPU and the display subsystem's hardware overlay acceleration (hwcomposer).

Known issues:

• Video playback is slower than on previous releases -- this is most noticeable when playing HD 720p video.
• Bluetooth is broken at the moment after changes for Qualcomm Bluetooth chipsets were merged into CyanogenMod.
• Current releases of Netflix do not work with CM10.2 -- version 1.8.1 is the last version known to work. If you want/need a newer release of Netflix, look into the Xposed mod, which provides a workaround for Netflix -- pastordl has done a nice writeup of the process here.
• ART (the experimental Android runtime introduced in 4.4) is not supported -- if you enable it, your system will not boot. (Workarounds may exist, but they are not going to be officially supported either -- use them at your own risk.)

Note that an updated recovery is required to install CM11. ClockworkMod 6.0.4.8 and newer versions should work, as should other recoveries provided the required changes are included. (Ask the maintainer of the recovery if you're not sure.) NOTE: Do not use ClockworkMod 6.0.3.x builds older than 6.0.3.6, as they contain a bug which may brick your device!

Build instructions (discussion of build issues belongs in the development thread)

This release is the product of much effort by many people over a considerable period: many thanks to fattire, keyodi, eyeballer, krylon360, dalingrin, verygreen, iomonster, nemith, cicadaman, deeper-blue, thedude, mad-murdock, j4mm3r, unforgiven512, scepterr, rebellos, ryands, kmobs, tonsofquestions, hashcode, arcee, hacdan, drmarble, mateor, dhiru1602 and many more. Thanks are also due to the CyanogenMod project, upon which we are building, and Texas Instruments, which historically provided excellent support for its embedded platforms to the open-source hacking community.

Google Apps; other CyanogenMod builds

Google Apps
http://wiki.cyanogenmod.org/w/Google_Apps

As of 2014/07/25, the latest release for CM11 that is known to work is 20140105. DO NOT use the 20140606 release unless installing to SD card -- it contains over 100 MB of additional bloat and will not fit on an eMMC installation!

If you wish to use another Google apps package, and are installing on eMMC, please note that the Nook Color has what is by modern standards a limited amount of disk space available on /system (440 MB) -- the base system is currently in the neighborhood of 300 MB, so some of the larger packages will not fit. If you're offered different variants, choose the smallest one in order to avoid problems.

Please make sure that you have the correct Google Apps flashed before reporting problems involving the Google Apps (Play Store, Google Keyboard, etc.).

Other CyanogenMod builds

This is the thread for CM11 nightly builds. There are other official CyanogenMod builds for Nook Color available:

• Stable releases of CM10.2 and CM10.1 -- these are the releases to use if you don't want to be on the bleeding edge.
• Archived nightly builds for CM10.2, CM10.1, and CM10. You may find the last CM10 nightly (20130421) faster than the later releases, particularly during playback of HD 720p video.

Please check that your questions are in the appropriate thread. (If you're interested, there's lots of past discussion in those threads, as well as the development thread.)

Frequently Asked Questions and Troubleshooting

The install fails with errors from "set_metadata_recursive"!
The installation appears to succeed, but nothing's changed when I reboot!

You'll need an updated recovery to install CM11. For CM11 nightly builds from May 16 and later, any recovery that reports itself as ClockworkMod 6.0.4.8 or later should work; other non-CWM recoveries should work if they incorporate the necessary changes to suppor these builds (you'll have to ask their maintainers for details).

For older CM11 nightlies, any recovery that reports itself as ClockworkMod 6.0.3.6 or later should work; other non-CWM recoveries such as TWRP 2.6.3.0 or later should be fine provided the kernel is sufficiently new (you'll have to ask their maintainers for details). NOTE: Do not use ClockworkMod 6.0.3.x builds older than 6.0.3.6, as they contain a bug which may brick your device!

I installed CM11, wiped /data, and now my tablet's been booting for an awfully long time. Is something wrong?

First boot will take at least five minutes, and the boot animation currently stops many times during this process. If you've been waiting more than 10 minutes and it's still not booted up, you probably have a problem.

The soft keyboard keeps crashing!
The Play Store is acting up!

Did you flash the correct Google Apps? If on an eMMC install, are you sure your Google Apps fit on /system?

How do I install this to an external SD card?

See this excellent guide by leapinlar for instructions. It's reported that Google apps installation is broken in the SD card installer at the moment, so you may need to wait for that to be fixed.

What happened to the "Developer options" and "Performance" screens in Settings?

They're hidden by default now in CM10.1 and later. To show them, go into "About tablet" and tap the build number (for CM11 nightlies, it'll be something starting with "cm_encore-userdebug 4.4.2 KOT49H" or "cm_encore-userdebug 4.4.3 KTU84M") seven times.

How do I get the Honeycomb/ICS tablet UI?

You can't -- Google killed it off in Android 4.4.

The lock screen doesn't rotate!
The screen doesn't rotate to the sides I want!

Particularly if you're upgrading from an existing install, you may find that the preferences for screen rotations are incorrectly set. Go to Settings->Display->Rotation and check that "Auto-rotate screen" and (if you want the lock screen to rotate) "Rotate lock screen" are set.

For the allowed screen orientations, selecting 0, 180 and 270 degrees will cover the rotations that you probably want. If you want details: I enabled ART, and now my Nook Color won't boot!

ART isn't supported on Nook Color at the moment due to known issues:

• The initial compiling pass that happens the first time you enable ART may cause your tablet to run out of both RAM and disk space.
• Many of the Google apps packages for CM11 are incompatible with ART.

If you're currently stuck in a bootloop after enabling ART, boot into recovery and then see this post by fattire for advice on how to restore your system to a working state.

I can't get any of the ROMs or recoveries for Nook Color to boot!

Before you go any further -- are you sure you have a Nook Color and not a Nook Tablet? The two devices look almost identical, but Nook Color (model number BNRV200 -- check the fine print near the speaker grille on the back) has a dark gray bezel, while Nook Tablet (BNTV250) has a light gray or silver bezel. The two devices are not interchangeable -- Nook Color software will not boot on Nook Tablet and vice versa.

If you've got a Nook Tablet, you want to be in the Nook Tablet forums instead.

I'm having a problem with my Nook Color running CM11.

That's not a question

Okay, I'm having a problem with my Nook Color running CM11 -- is there something I can do to troubleshoot?

Glad you asked! Please check the following:

• Does the problem occur with a clean install of CM11? This means wiping /data and not restoring a Nandroid backup afterwards. Don't restore system apps and/or their data in Titanium Backup either (user apps/data are okay).
• Are you overclocking? If so, does the problem occur when you set the maximum clock speed to 1000 MHz or below? To be clear, we are not interested at this point in bug reports of any kind that happen if you have the maximum CPU speed set above 1000 MHz. If you're experiencing system crashes or "sleep of death" (SOD), you may also wish to try capping the CPU clock speed to 800 MHz (but if this helps, please report your problem here and fill out the hardware survey).
• Do you have any patches, custom kernels, or other tweaks applied? If you do, does the problem occur without those applied? (We're not necessarily going to ignore bug reports from patched or tweaked systems outright, but it can make our job harder, and we do need to know what changes you have applied to judge whether or not the change might be relevant to your problem.)

I'm having no luck with the suggestions above. What information should I include with my bug report?

When reporting a problem, please include the following information if at all possible:

• Full description of the problem -- "it crashes" doesn't count. How do you trigger the problem (or does it occur by itself)? What exactly happens when the problem occurs? How often does it happen?
• For problems with apps or specific pieces of the system software: we'll almost certainly ask for a logcat of the event, so you'll save everyone some time by including it.
• For problems involving system freezes, crashes, or SOD: if you can connect to the tablet via adb while it's "unresponsive", please provide dmesg and logcat output from that time. If you cannot, try power-cycling it while it's still plugged into USB, and provide dmesg output from immediately after the reboot, plus the contents of /proc/last_kmsg if that file exists (let us know if it doesn't).
• For unexpected reboots: provide the contents of /proc/last_kmsg from after the reboot.

Hello everyone,

To run off of an SD; I created a new SD (sandisk 8gb) with the latest image from Leapilar, the nightly and suggested GAPPS (gapps-kk-20140105-signed.zip). There were some error messages from the GAPPS (they scrolled off before I could really read them). The NC booted to the desktop but there was no play store.

Any ideas?

Thanks,

V

If your errors match the ones reported on the SD installer thread:

I then tried to install the 2014/01/05 gapps package using your/verygreen's script and saw this message:
"Hangouts.apk exists but is not a regular file" The script died at this point and shutdown. After booting, you cannot add a google account as it appears it is a very incomplete gapps install.

then it's the bug mentioned in the FAQ -- it looks like the SD installer needs an update.

Just flashed in it looks great! Feels MUCH smoother and snappier then 10.2. Minor issue that boot take a long time. It seems to me like the boot keeps freezing but eventually continues. No force closes or anything. I am trying now to enable ART and play with it a little to see if it drasticaly improves it. It seemed to make a little bit of a difference on my S3.

Edit: You may want to add to the op, DO NOT enable ART. It sends it into a reboot loop.

Yeah, actually steven, if someone has issues with ART you might wanna link here. You can recovery from an ART bootloop w/o reinstalling or anything weird.

Yeah, release noted and added to the FAQ. We'd known about this earlier, but it slipped my mind when I was writing up the release notes

bowguy said:

We are working on it. There is a modification pending that might fix this but hasn't been tested yet.

Be aware that this may not work for you if you've installed to eMMC on a Nook Color with a 1 GB /data partition -- disabling the boot animation saves RAM, but won't prevent you from running out of disk space to store the ART compiler output (the "oat" files).
