IMO, ART is the only reason to go to KitKat (other than the fact it's the only thing currently supported). JellyBean seems stable in most everything else and yielded much better battery life for me, on all devices including my cell (S3). UI was much more intuitive with built in status bar toggles which are so much better than quick tiles IMO (there's a reason even iOS 7 went to those toggles, not sure why KitKat went away from them), activity indicators on the status bar were great, and I literally had zero crashes, etc. KitKat is simply snappier with ART enabled as it precompiles apps instead of doing it on the fly dalvik style but I still prefer JellyBean as it's stable as a rock.

That being said, I've had no problems with running CM11 nightlies on this thing but I also don't do much with my Nook other than browse a few websites, use the Dish Anywhere app to remotely watch TV, use Plex to remotely watch TV shows from my NAS, and stream the stuff to Chromecast when I don't have my phone handy (it's basically my portable media player when I need a larger screen than my phone). Handles all that with ease.
[Nook HD, HD+ Android Development] TheDannemand:
I was merely making a joke playing on the words in agantai's post -- think Michelangelo vs Picasso or Mozart vs Shostakovitch.

I definitely was NOT trying to resurrect the debate about the pros and cons of ART vs dalvik -- which I agree does not belong in this thread.
[Nook HD, HD+ Android Development] w1ll1m:
I have a problem, was running cm11 m4 on the nook HD and all of a sudden the notification and settings drawer no longer pulls down. Also the Home soft/hard button doesn't do anything, and I can't quit out of apps unless I use the back soft key to exit the app stage by stage. Plus the screen no longer locks, pressing the power button to sleep and then to wake the device leaves it fully unlocked. I have updated to the latest nightly but problems persist, any help?
[Nook HD, HD+ Android Development] huntz:
You can use some alternative launcher, like Nova Launcher (search it on the play store).

On my setup, the new launcher resolved some of your problems...

Give it a try...
[Nook HD, HD+ Android Development] w1ll1m:
Tried nova launcher and all the problems persist. Notification drawer pulls down but shows no notifications and the settings drawer wont pull down.
[Nook HD, HD+ Android Development] NishantM:
I had faced this problem in one of the march nightly, don't remember the exact one. The only way out was a factory reset and reflash.
[Nook HD, HD+ Android Development] mr72:
I had this issue with one of the early April nightlies. Flashing the 4/17 fixed it. Also had an issue with the 4/17 where settings would not run. Reboot fixed that. I seriously doubt you need a factory reset.
[Nook HD, HD+ Android Development] w1ll1m:
Yeah, hoping to avoid that atm, that will be the final option.

I was on the m4 snapshot but i have update to 19/4 nightly and a reboot hasn't resolved the problem. I have wiped cache from the recovery but that hasn't helped, but it looks like a factory reset option is the only way.
[Nook HD, HD+ Android Development] Classpro:
Google play would not download on 4/20 nightly (art). Went back to 4/11.

Only real problem is messed up touchscreen every once in a while, which is fixed by cycling the screen off. Any solution to that? Appears to be random
[Nook HD, HD+ Android Development] JanSpatschek:
have this problem once in a while. turning off the display fixes it. has been in CM10.1 - CM11 ROMs.
[Nook HD, HD+ Android Development] BigMacca:
I have got the same problem on my Dad's HD+ - I updated it from a Nightly to the 21st April nightly yesterday and I couldn't get the home button or the settings drawer to work.

I'll try re-flashing a newer nightly in a couple of days I guess....
[Nook HD, HD+ Android Development] tebra:
Already asked but never get a replay:

Did you get your location on google maps app on your HD/HD+ with CM11 nightly? If yes, tel me which nightly.

Thanks
[Nook HD, HD+ Android Development] rhyang:
Not working for me either, on 4/21 nightly. Something broke it I guess. Watching the change logs...
[Nook HD, HD+ Android Development] sz0pf1:
I continue to run on the 327 nightly running ART and I have virtually no problems. Although it is a pain to have to completely re-set up your device, when you begin to experience some of the issues being discussed, you may not have another option other than to do a clean install.

Do a hard reset and then install the currently nightly and you hopefully will eliminate some of your problems.

When you don't do a hard or factory reset, you can't be guaranteed that there is not some stray code left behind that is corrupting the operating system.

Of course, if the code is broken, then you will have to go with a different nightly.
[Nook HD, HD+ Android Development] Jann F:
Please read...

The fact that you guys don't even know what nightlys are for makes me cringe everytime I look into here.

Nightly's are testing builds and only the newest ones are useful for reporting bugs, as bugs of older nightlys may have been already fixed.

Please guys, before reporting any issues, do a clean install of the newest nightly and test it again.

If you wish to use a stable ROM go to CM10.2 or compile AOSP KK 4.4 yourself.

A word to ART:

Why?

Why do you even complain about breaking an experimental feature implemented by google and not even being visible to normal users without enabling it in dev-settings?

It isn't meant to be a daily used feature yet unless google releases it as a default option or at least an option outside dev-settings.
[Nook HD, HD+ Android Development] mr72:
Will you feel the same way if ADB is broken? Or GPU rendering?
[Nook HD, HD+ Android Development] Jann F:
Is adb experimental? NO!

Is GPU rendering experimental? NO!

I'm tired of reading through tons of pages where people just write what dated nightly works with ART.
[Nook HD, HD+ Android Development] TheDannemand:
If nobody takes the bait, this will be over soon, and we can get back to reporting and discussing CM11 issues.
[Nook HD, HD+ Android Development] Nupraptor:
I've had nothimg but trouble with CM11. I want to roll back to 10.2; Can I simply flash 10.2 over 11, wipe cache/dalvik, and be good to go?
[Nook HD, HD+ Android Development] digixmax:
You'd need to roll back to an older recovery version, reflash ROM and Gapps, and most likely also need to do a "wipe data & factory reset".

FWIW I've been using the M4 snapshot, it's no bug free but very much usable.
[Nook HD, HD+ Android Development] Jann F:
You should use helium to backup your appdata, don't restore data of system app's as it can lead to problems.

You don't have to use an older recovery, you just have to remove the following line from the updater-script within the package:

assert(getprop("ro.product.device") == "ovation" || getprop("ro.build.product") == "ovation");
[Nook HD, HD+ Android Development] leapinlar:
Please don't recommend users to remove that line. It is there for a good reason. What if they accidentally try to flash an ovation zip to a hummingbird? Removing that line would allow it to happen. You would have contributed to their mess.

A much safer approach is to replace the update-binary file in the older zip with one from a CM11 zip.
[Nook HD, HD+ Android Development] mircury:
I think I found a bug. Can anyone verify this? I'm on 4//22 ovation nightly.

When you connect bluetooth to a speaker/headphone and you switch to a different user on the unlock screen, bluetooth crashes and also cyanogenmod accounts crashes. You have to reboot to get bluetooth back for the "owner". I'm not using ART. The second user cannot use bluetooth at all no matter what I tried.
[Nook HD, HD+ Android Development] Bossk128:
There is an awful lot of instability going on here! I'm using CM11 20140226 with pretty much zero problems. I do use ART and found performance and battery life both improve. Bugs I do have:

Spontaneous reboot twice in one evening happened once only

Regularly get the toaster notification that Google Sound has stopped. I notice no symptoms.

And that's it. I'm not moving until a stable version is available.

However I know some things can be app specific so YMMV.
[Nook HD, HD+ Android Development] Darrian:
I've been experiencing an unusual bug the last few nightlies. Everything appears to be fine, but then when I go to pull down the notification tray it appears that systemui crashes (it closes out, reloads, and puts me back at a lock screen, but no error pops up). Then I may or may not get several force closes on a handful of other apps. I just did a clean install yesterday to try to fix it, but to no avail.
[Nook HD, HD+ Android Development] razholio:
Both of you make good points. Might I suggest that if ART is not a supported feature in CM (as you appear to suggest) that we *not* report bugs on it to CM, and for those of us who do find ART useful, we are allowed to discuss which builds to avoid because of ART breakage? While I'm not supporting an endless flame war on the subject, I do find it unacceptable to shutdown any discussion of unsupported features. If they are features found useful, then discussion of them seems relevant to me in this forum.

I might point out that had you not responded to any of the ART posts, there would be far fewer of them to 'read through', nearly by half.
[Nook HD, HD+ Android Development] RocketOptics:
I was having the same issue on nightly 20140418 on my HD+. It seems to occur after the tablet was idle for a while.

I just loaded nightly 20140422, wiped cache & Dalvik and let it sit for 2 hours. The problem seems to have gone away. Not sure if it was the build or the cache/Dalvik wipe that resolved it. I'll keep an eye on it.
[Nook HD, HD+ Android Development] RocketOptics:
Nope, spoke too soon. Played Candy Crush, and then exited. HD+ was slow in loading the home screen. As soon as I touched the notification bar, the problem was back.
[Nook HD, HD+ Android Development] Blenky:
I have the same issue issue on 20140418. Have you got ART enabled?
[Nook HD, HD+ Android Development] Darrian:
Yeah, I wipe my Dalvik and cache regularly to no avail. Just hoping a future build fixes it soon. Checked switching to ART, too, and that didn't seem to help, either.
[Nook HD, HD+ Android Development] RocketOptics:
No ART.
[Nook HD, HD+ Android Development] huntz:
I'm with nightly 20140418, yesterday I've made a factory reset (wiping data/cache/dalvik) and reinstalled and configured everything again, but the problem persist.

It seems to occur after the tablet was idle for the night.
[Nook HD, HD+ Android Development] mr72:
I have not seen this issue other than maybe a once in a month quirk, maybe because I don't play candy crush or maybe because I don't have the lock screen enabled. Might narrow it down to try without the lock screen. I doubt ART has any effect since I have run with dalvik for days at a time and still have not seen something like this consistently.
[Nook HD, HD+ Android Development] Jann F:
Same issue here, when attempting to pull down notification bar, system UI seems to crash.

I will log it with adb tomorrow if I have some spare time.
[Nook HD, HD+ Android Development] dorfd1:
I am thinking about get the nook hd and wonder if the emmc install supports the 8gb nook hd?
[Nook HD, HD+ Android Development] Darrian:
It does, yes. Make sure you get the right CWM and download the build for Hummingbird, NOT Ovation.
[Nook HD, HD+ Android Development] Sherip:
I came across some settings that eliminate screen flashing or blackouts when returning to the desktop. In Settings, Developer options, check Force GPU Rendering and check Disable HW Overlays. Works great for me.

On my nook it shows that the systemui has crashed which is what appears to be causing the problem with the notification pull down - unless I missed something.

E/ActivityManager(445): ANR in com.android.systemui
[Nook HD, HD+ Android Development] Xyriin:
While ART should not take priority, imo it would be irresponsible to skip reporting ART bugs. ART is coming. Sure it's not going to be here tomorrow but it will be the standard soon. It would add a lot of work in the long run if every bug was fixed ignoring ART and then when the ART switch is flipped to bug fix from scratch. Just my two cents.

Personally I do run ART, and I just switch to Dalvik when ART is broken. Dalvik is an inferior way to operate but it is what it is until Google makes it the default (hopefully this I/O). A good middle ground would probably be for the ART-haters to be a bit less evangelical and for the ART-lovers to recognize that ART isn't the default yet when bug reporting.

Hello. I'm having a very weird issue with M5 Build of CM11.

I've been having full hardware shut offs when an app starts with a very load sound. IE Hello Kitty Cafe. I open the app, it has a massive load time (10-15 seconds). Then when the music starts the tablet shuts off. This has been done at various battery levels. I feel its just a hardware issue and I have a workaround for it. But I wanted to see if anybody can reproduce this and I'll upload LogCat.
[Nook HD, HD+ Android Development] snoozer854:
Has this issue been resolved yet?

I don't play games

I have had it happen without pulling down the notification window.

Could be just typing like now & things would freeze up then go to lock screen then things resume as normal.

Right now I am using the 4-28-2014 nightly, but it has happened since a few updates back.

I seen where someone mentioned turning off lock screen, how do you go about doing that?

Hopefully this issue gets resolved soonn

Thank you

Mark
[Nook HD, HD+ Android Development] Manwthgun:
I did a clean wipe and loaded the nightly 4/28 now my nook wont shut off. Any suggestions?
[Nook HD, HD+ Android Development] leapinlar:
How did you do the 'clean wipe'? And what were you running before you loaded the nightly?
[Nook HD, HD+ Android Development] Manwthgun:
Using CM10 prior. Factory reset/Wipe Dalvik then installed GApps after ROM install

---------- Post added at 03:04 PM ---------- Previous post was at 03:01 PM ----------

Followed OP I did change from CWM to TWRP but, wiped and fix permissions prior to install.
[Nook HD, HD+ Android Development] leapinlar:
The only thing I can suggest differently is to wipe /system also so that the old gapps from CM10 get wiped too.
[Nook HD, HD+ Android Development] mr72:
Is the latest 4/30 nightly working OK especially with art? Tying to avoid wasting time on an update. Thx.

After trying some nightlies, I'm back on M4 too. With a factory reset, M4 is the best stable for me.

Now I have 4 days of uptime and all is working nicely (I don't use ART)

After trying a few nightlies, I'm back to 04/11. That has been pretty stable for me. What is the date on M4?

[Nook HD, HD+ Android Development] kawaski47:
I updated from 10.1.3 to 10.2.1 and hangouts and the play store stopped working. Hangouts would force close and play store would not connect. I did this via a cache wipe and not a complete wipe. Any ideas?
[Nook HD, HD+ Android Development] TheDannemand:
I would post this question in the CM10.2 thread. This is CM11.
[Nook HD, HD+ Android Development] snoozer854:
Trying the 4-30 nightly today with hopes the notification issue is fixed. Will post an update on how it goes later.
[Nook HD, HD+ Android Development] snoozer854:
Problem is still there. Was using Google plus noticed things slowing down a few of notification icons disappeared, but instead of being taken back to lock screen a reboot was done.

Anyone have a March nightly?

Before I made the mistake of updating this week I was using a nightly from March 18th I think.
[Nook HD, HD+ Android Development] excalibar001:
I tried a few April builts but they are all broken. I used catlog to view the logs and there was a mayhem behind those slowdowns with processes dying en masse.

I am currently using 03/30 and very happy with it. ART works though not much faster than dalvik. You can download it from here.

https://mega.co.nz/#!uAAFEYjS

After installation, give it a day to let things settle down. As someone said earlier, force GPU rendering and hardware overlay really speed things up.
[Nook HD, HD+ Android Development] rholm:
Did you try 04/11? It has been pretty stable for me.

Cheers,

[Nook HD, HD+ Android Development] snoozer854:
No I haven't until I got the bright idea of updating this week last time I updated was way back in March.

I normally do a backup in recovery before upgrading, but the backups since upgrading everything to work with CM 11 is so darn slow takes over 2 hours to do. I have been skipping it lately

Wish I would have backed up.

Thank you

Mark.

[Nook HD, HD+ Android Development] SCWells72:
I'm on a build from a few days ago and I'm seeing the same issue with the notification pull-down crashing SystemUI, though it only seems to happen for me the first time I access it after waking the device up. I only use the Nook HD+ now as a comic reader (I have a G Pad GPE as my primary daily driver), so it doesn't really affect me that much, but I'm still hopeful for a fix soon.
[Nook HD, HD+ Android Development] mr72:
I haven't seen this bug ever. Is it app-specific?
[Nook HD, HD+ Android Development] SCWells72:
Doesn't seem to be. I turn on the Nook HD+ running a recent build of CM11, swipe down on the top-left of the status bar to show notifications, and the device seems to lock up for about 10-15 seconds before restarting the system UI into the lock screen. After that things seem to work fine until it sleeps and wakes again. This has only started to happen on recent builds, though I couldn't identify the exact build that introduced it.
[Nook HD, HD+ Android Development] mr72:
I think this must be lock screen specific. Mine has never done anything like this, and I just tried it several times, no problems.

Maybe try setting the Lock Screen to "no lock", see if the problem persists? Just to help identify if it is related to the lock screen or not.
[Nook HD, HD+ Android Development] excalibar001:
Updated the links. Sorry it is for HD+. Someone else have to help you with HD files.
[Nook HD, HD+ Android Development] snoozer854:
Thanks for trying to help me out.

I have noticed it isn't returning to the lock screen quite as often today with the 4-30 nightly so maybe it is getting closer to being fixed.

Thank you for the suggestion, but I just tried that and it still does it. ugh

---------- Post added at 03:46 PM ---------- Previous post was at 03:41 PM ----------

Well it did it again running the 4-30 nightly, so downloaded the 5-1 nightly & it did it right away.

Beginning to think I am going to have to wipe data etc and go with the snapshot-M4 it looks like.

Does anyone out there have a March nightly file that they could share that will work on the Nook HD?

If you do I will be forever indebted to you. I really hate to have to wipe this and start over.

Thank you everyone for taking the time to read this

[Nook HD, HD+ Android Development] rhyang:
I've been seeing the notification bar issue also, but see it as more of an annoyance than anything else. Mostly happens when i get an email. I've read that some other devices have the same problem, so probably it will be fixed soon (more eyes on the problem).

Been running the 4/28 nightly for the last several days. Location seems to work, but when the notification crash happens it seems location stops working too, until the next reboot. Hmm.

Good times :)
[Nook HD, HD+ Android Development] mr72:
Maybe it is related to location? Some other setting? Or hardware? Because I have never seen anything like this on my HD+ and one would think if it were so common I would have. So I have to guess it is something related to my config. If you are interested in trying then I can screen shot my settings.
[Nook HD, HD+ Android Development] Blenky:
I'm running 20140501 (with ART) and the notification bug has gone.
[Nook HD, HD+ Android Development] snoozer854:
An update. Using 5-1-14 build on my Nook HD. When using say Google Plus & a notification comes in either email or twitter tablet will crash at times & reboot other times will return to lock screen.

Other builds this week would not cause a reboot, but a return to lock screen.

On the 5-1 build it is not happening as often as earlier this week.

Maybe it will be fixed next week.
[Nook HD, HD+ Android Development] RYARNI:
Hmmm I don't know if this is really related as it involves flashing something else. I can no longer write to my SD card after flashing 'USB Host Switcher'. The micro SD works fine plugged into an adapter on my PC, but as soon as I put it back in my Nook and move any file to it I get the error 'Error - Could not write file'. Any ideas?

This happened straight after flashing the above, which read my USB stick but I could not delete/write to it. Sorry if this is the wrong place. :good:

(SD card is a Samsung 32GB Class 10, working fine previous to flash)
[Nook HD, HD+ Android Development] christrance:
Try software sdformatter. Sorted mine out.

Anyones resolution messed up? Homescreen apps only width of half the screen. Fine apart from that.

For example the google search bar only takes up half width of screen and only 4 apps go at bottom of screen.
[Nook HD, HD+ Android Development] RYARNI:
Tried this already, and again and not working. Had to switch to a back up of Succulent's rom. Annoying because this rom was working perfectly until then

I'll figure it out. :good:
[Nook HD, HD+ Android Development] christrance:
I understood you wrong. The sdcard is a problem with the first posted ROM. Look at end of OP for fix. Works A1. I thought you meant your card wouldn't work in laptop either after flashing SD image.
[Nook HD, HD+ Android Development] RYARNI:
Ahh, brill. Thanks! I think I may have flash the latest update (9th at the time) with USB host switcher, hence the confusion.
