Free RAM is wasted RAM.

RAM management on Mobile platforms differs from PC.

Free RAM doesn't mean that it's good. The less free RAM there is, the more efficient your device will run. Well, the efficient part is on me, but what I mean is, less free RAM won't slow down your device. If another process or app needs RAM, the OS will ask another process/app that has bèen inactive for a while TO DIE. And if it doesn't want to, android will kill it. c:

Free RAM is wasted RAM. IF IM WRONG ON ANYTHING I APOLOGIZE AHEAD OF TIME AND PLEASE CORRECT ME.

On a side note, 3/23 definitely is stable.
[Nook HD, HD+ Android Development] mr72:
If you read the changelog you may find that very little if anything that affects our device was changed between the 3/22 and the 3/23, and there is very little affecting the ovation on the upcoming next nightly either. We don't have Samsung, we don't have a camera, we don't have telephony (that works), no dialer, no LTE radio, etc... My point being, 3/23 may be stable, but it's not meaningfully different from 3/22 (which I am running, and is also pretty stable so far), and 3/24 is not going to be any different either, so far.

I noticed yesterday that my Dish Anywhere app doesn't work. It refuses to find/connect to the DVR. This worked on CM10.1. Anyone else tried this, have any idea or success? I think I may clear data for the app and retry it, maybe reinstall the app.
[Nook HD, HD+ Android Development] Jack45:
I had Dish Anywhere on my Skyrocket, but not on the HD+. Just installed it and it works fine. Using 3/23 nightly.

Anybody has issues with Google maps, it won't zoom to my location. It says waiting for location, then do nothing. Thx
[Nook HD, HD+ Android Development] fabioc:
How do I fix this?

This happens when I use Auto Update. It started back in January and I tried several things, including factory reset with no luck...
[Nook HD, HD+ Android Development] JimJ2Mz:
What's "degreenify java?" Sounds interesting.

It's in the 3/24 changelog.

And yeah, the latest changes don't really do anything for ovation. -sigh-

I hope later on there are fixes for our device. And hummingbird too.

That looks REALLY weird.

Have you tried reinstalling recovery?

Reflash EMMC recovery.
[Nook HD, HD+ Android Development] Whyzor:
Anyone know what CyanogenMod's policy is for merging AOSP commits? For example I see more recent commits to the AOSP ART platform:

https://android.googlesource.com/platform/art/

But Cyanogenmod's ART repo hasn't been updated in about a month.

https://github.com/CyanogenMod/android_art/commits/cm-11.0
[Nook HD, HD+ Android Development] fabioc:
Yep. I have tried to reinstall Recovery.
[Nook HD, HD+ Android Development] JanSpatschek:
Good to know that 3/23 is stable. But can anyone explain to me why I get random reboots on EVERY CM11 Nightly I try.

Succulent's CM11 builds don't give me constant kernel panics. I would feel "better" if this happened to more out there, but I seem to be the only one.
[Nook HD, HD+ Android Development] jdjohn:
I was getting random reboots and a flickering screen with M4 from 3/8, but a double factory wipe and clean install of 3/23 is working good so far.
[Nook HD, HD+ Android Development] JanSpatschek:
I will give it a try!
[Nook HD, HD+ Android Development] Darrian:
I am finding 3/23 to be incredibly unstable and get flickering all the time with a clean install.
[Nook HD, HD+ Android Development] blautens:
Dish Anywhere is quite fickle - a number of things can cause it not to connect - I won't go into the crazy things I have discovered. But as someone already posted - it is not a fundamental issue with CM11.

Sent from my Samsung Galaxy Note 2
[Nook HD, HD+ Android Development] JanSpatschek:
So 3/23 hasn't given me a reboot, which is nice. But it seems to lag as hell. Transitions are so choppy, the status bar tends to react really late. Will probably go back to Succulent's latest build. It is so smooth.
[Nook HD, HD+ Android Development] xflier:
Did you do clean install with wiping data? I had the same issue, but after a clean install, it is good so far
[Nook HD, HD+ Android Development] excalibar001:
03/23 was not stable for me either. Very choppy transitions and random reboots. Moved back to my last stable configuration 03/08.

[Nook HD, HD+ Android Development] JimJ2Mz:
Everyone's been talking about a data wipe when installing a new nightly and now I'm scared I've been doing the update process incorrectly. I mean, I use CMupdater and then I just wipe cache + dalvik cache and that's about it. Also, 3/25 is out with lots of fixes and some of them are video related. There's also a fix for omap4. Maybe this will fix some issues with video playback for us?
[Nook HD, HD+ Android Development] mr72:
I never do the wipe data. Just use CM Updater. Rarely do I do the cache/dalvik wipe either.
[Nook HD, HD+ Android Development] Blenky:
Same here. I've got two HD+ and just use the app to install new builds. Never wipe and everything is fine for me. On 18/3 build at the moment.
[Nook HD, HD+ Android Development] Darrian:
That is how most of us do it most of the time. Don't worry.
[Nook HD, HD+ Android Development] Whyzor:
I haven't tried every nightly, but 3/10 & 3/18 do still randomly reboot VERY rarely. Not really an issue. Sometimes screen has the garbled 'static' look, like the initial sdcard boot interrupt screen before rooting & flashing custom recovery. Most of the time I can close magnetic case lid, press power a few times & it comes back online fine. A few times had to hold power to give it a hard reset. Likely a kernel or hardware bug, but it doesn't happen often or consistently enough to bother me right now.
[Nook HD, HD+ Android Development] Darrian:
I had just come back from trying rooted stock and being unable to tolerate it, so everything was wiped, including data.
[Nook HD, HD+ Android Development] PMikeP:
After learning about the CM changelogs, I just updated to the cm11-20140325 nightly. Looks like there's only a short list for stuff planned for the next.

One problem I've noticed when charging the HD+ is screen flicker on screens with black backgrounds. The flickering seems to be in sync with the animated charging "icon" in the status bar. (I have mine set to text, if that matters.) I noticed this with the 20140322 nightly too.
[Nook HD, HD+ Android Development] JanSpatschek:
Okay. I would still be nice if the Kernel problems like the reboots and the flicker could be fixed. Maybe [MENTION=3654172]verygreen[/MENTION] could contact Succulent, because his Kernel shows none of those problems.
[Nook HD, HD+ Android Development] JimJ2Mz:
?

Is it better to use the built in CM Performance settings for CPU modifications or should I use an app like setCPU?
[Nook HD, HD+ Android Development] jdjohn:
But Succulent's last update was 3/7, correct? Was that just before M4?
[Nook HD, HD+ Android Development] PMikeP:
I bought the HD+ primarily to use in the cockpit as a moving map. It has shutdown on two flights. (Not a reboot. Took a ten second power button reset to restart.) 3/08 and 3/23 builds.

Since it has only done that when running the aviation maps, I don't know if it's CM 11 or the maps. My Gal Tab 2 doesn't crash when running the same maps on JB 4.2.2 with an AGNi kernel.
[Nook HD, HD+ Android Development] kangi26:
It's possible the map app isn't optimized for KitKat yet
[Nook HD, HD+ Android Development] JanSpatschek:
That's right. 3/7. And all of the previous builds: no reboots, no flicker.
[Nook HD, HD+ Android Development] Whyzor:
If an app isnt compatible with android version it would force close, a whole system freeze or reboot is a low level problem likely kernel issue interacting with the hardware.

I should mention my freezes and crashes are with ARTruntime, so not sure if the experimental nature of that is affecting it. And there have been a lot of commits to the AOSP base that CM11 hasnt picked up in the past month or so.

Does the other ROM use a different kernel?
[Nook HD, HD+ Android Development] JanSpatschek:
It does. That's why I think verygreen could get some advice from succulent. But probs to both devs!
[Nook HD, HD+ Android Development] Whyzor:
Thanks for the info, I might switch over to that one after the next build since I dont care to be on the bleeding edge of CM11, but want something stable. Both their repositories are public, so whatever kernel/device fixes each dev made should be visible to the other. It just takes some time and and maybe some nudging to merge them.

Actually it is the responsibility of the Cyanogenmod maintainer for Nook HD+ (whoever that is, he exists since ovation is officially CM supported) to pull in all the fixes from different dev repos so they get automatically included in future nightlies.
[Nook HD, HD+ Android Development] king200:
Maybe someone can experiment with succulent kernel in this app? You might try flashing succulent boot.img with "Flashify" from Playstore or substituting boot.img in the .zip file using 7Zip. If things go wrong, flash the original .zip or restore a backup.

Certainly, Android backup first.

PS: I don't seem to have any problems with the 0326 build
[Nook HD, HD+ Android Development] JanSpatschek:
CM11 Nightlies don't boot with succulent's kernel
[Nook HD, HD+ Android Development] TeutonJon78:
That would be verygreen.
[Nook HD, HD+ Android Development] JanSpatschek:
Yup, he should check out Succulent's repos.

Also I found a bug in all CM builds. If you use Nova Launcher and choose a Wallpaper through "Set Nova Wallpaper" and take the "Portrait - Tool" to cut your Wallpaper, you will get screen flashing will switching between Apps through the recent Apps panel.

If you choose your Wallpaper with the "Full - Tool", those flashes go away.
[Nook HD, HD+ Android Development] henry8668:
I am currently using emmc CarbonROM which seems stop updating.

I want to flash CM11 M4, can I just upgrade from CarbonRom, or need to go thru new installation?
[Nook HD, HD+ Android Development] jdjohn:
"Full Tool" - I've met a few of those over the years ;) I was getting screen flickers with M4 while in Settings...not even going between apps.

I would not recommend flashing M4...very unpleasant. And then later I found this: http://xdaforums.com/showthread.php?t=2675591
[Nook HD, HD+ Android Development] JanSpatschek:
Don't get the joke. Try it man, you will get flicker while switching between Apps.
[Nook HD, HD+ Android Development] henry8668:
That's for those that mixed nightlies and milestones, if I only install M4, would that be ok?
[Nook HD, HD+ Android Development] JanSpatschek:
Try this one, much more stable: http://goo.im/devs/succulent/ovation/cyanogenmod/internal/cm_ovation_11.0_07MAR2014_HD.zip
[Nook HD, HD+ Android Development] henry8668:
Is this the one before M4? I didn't find it here though: http://download.cyanogenmod.org/?device=ovation&type=

My other question is can I just wipe cache and install it over carbonRom?
[Nook HD, HD+ Android Development] JanSpatschek:
No it isn't from the Official CM website, it is from another Developer. It is more stable than the Official builds.

No, I would backup your Apps and clean flash it.
[Nook HD, HD+ Android Development] jdjohn:
The 'M' in M4 is for 'milestone', and I think that's a misnomer. You would think that's a sign of something solid, but in IT project management, it usually indicates a transition or new phase, so more like the beginning of something new instead of an end point.

Sorry, "tool" is a slang term often used for a vain and egotistical guy. My comment wasn't directed at anyone here, but struck me as amusing as "Full Tool".
[Nook HD, HD+ Android Development] digixmax:
I'd suggest you do a clean install (i.e. with "wipe /data & factory reset"); if you had enabled Google Backup & Restore, your Google Playstore apps will get automatically re-downloaded.

But you can also just try doing a dirty install and see if you can get away with it, worst case you'll just need to retry with a clean install.

FWIW I've running snapshot M4 since the day it got released and I have not had any problem whatsoever.
[Nook HD, HD+ Android Development] JanSpatschek:
Haha, okay - always room in my english dictionary!
[Nook HD, HD+ Android Development] jdjohn:
Kein problem :) Literally, tool = penis. Having a tool is one thing, being a tool is another.
[Nook HD, HD+ Android Development] JanSpatschek:
Sehr gut ;) Good to know. Now I can avoid confusion.
[Nook HD, HD+ Android Development] agantai:
i just tried latest CM11 builds 25 & 26 for my nook hd 7 inch & they're both broken,the settings stops responding & it takes too long for touch screen to respond. back to build 11

i thought newer builds have more fixes not glitches.

---------- Post added at 02:52 AM ---------- Previous post was at 02:21 AM ----------

the tablet is not performing well even on the build that worked fine for 2 weeks,it turns itself off & wont come on easly,its not as responsive as before.it just feels like 2 year old tablet when in fact its only 3 weeks old. does anyone know why the tablet is behaving this way ? its hd version not hd+ & its 16gb with more than 4gb free.

edit:

scrolling my fav web pages is no longer smooth.
[Nook HD, HD+ Android Development] JanSpatschek:
I would try doing a clean install (wipe system, data, cache and sdcard). Sometimes files on the internal memory from previous ROMs can mess up stuff on later builds.

Also maybe try installing CM10.2 stable.
[Nook HD, HD+ Android Development] agantai:
i appreciate the reply. i have done all the above,the only thing i changed is previously i used 8gb sandisk micro sd class 4 but i no longer have that card so i used another sandisk but 2gb & not sure if its class 4 or 2 ? could the problem be the micro sd card ? edit : i just tried samsung 2gb micro sd same problem.

also before i install CM11 i wipe everything first then i install CM11 & gapps then i do one more system wipe after all installs are done. is this wrong way of installing CM11 ?

i'm thinking about installing CM10.2 can i do this the same way i install CM11 or is there extra files needed ?
[Nook HD, HD+ Android Development] JanSpatschek:
No, basically I was just saying that wiping the sd card can solve some problems. But the class of the sd card isn't really important for an EMMC ROM.

Well, I hope you are not wiping "system" after installing the ROM. Because that would delete the installed files again.

What gapps are you using? I would recommend PA Micro Modular Gapps.

I have been having problems with the Official CM11 ROMs, so I would recommend CM10.2 Stable. To install CM10.2 you will need the previous version of CWM.

Also, of course, install the Android 4.3 gapps with CM10.2.

I have set up 4 HD+ for friends in the past and they are all running CM10.2 stable. No problems up until now. So I am sure that build is rock-solid for HD as well.
[Nook HD, HD+ Android Development] agantai:
yes i did but i wont wipe data after install is done ever again. i'm now installing again without wipe sys data after install.

pa_gapps-modular-mini-4.4.2-20140301-signed

this is the gapps i'm using with CM11.

if i can't fix this issue i will have no choice but to install CM10.2 by the way can i install previous CWM over the one already installed ? also do you have link for the stable CM10.2 i have found the thread but no mention of stable version. thanks
[Nook HD, HD+ Android Development] JanSpatschek:
Just wipe system, data, cache and dalvik cache, then flash ROM, then Gapps. Don't wipe anything after that.

Just download the Stable CM 10.2 here: http://download.cyanogenmod.com/get/jenkins/57360/cm-10.2.1-hummingbird.zip

Usually you can't install previous CWM. Make bootable sd CWM and flash previous CWM.
[Nook HD, HD+ Android Development] agantai:
ok do you mean i can't use my current CWM SD Card & i have to make a newer CWM SD Card ? once done is it ok to flash it over the newer one which is already installed ?

finally can you please direct me to the CWM needed ? also i ahve downloaded this UltraSlimGapps_JB4.3_CM10.2 i hope its the right one.
[Nook HD, HD+ Android Development] JanSpatschek:
You can use your current SD CWM.

CWM: http://nook.rootshell.ru/hd/cwm-recovery-hummingbird-2.zip
[Nook HD, HD+ Android Development] agantai:
thank you so much.

final question, i can install the CWM you just gave over the newer one i have already installed no problem ? also if i want to go back to CM11 can i install the appropriate CWM which is cwm-recovery-hummingbird-5 over the older one you just gave no problem ?
[Nook HD, HD+ Android Development] JanSpatschek:
You're welcome.

Yes, true. You can flash CWM over other CWM with no problem. You just need a SD CWM to do so.
[Nook HD, HD+ Android Development] agantai:
i really appreciate all the help you gave me. :)

as i said earlier i installed CM11 without wiping sys data afterwards so will give it a day or two to see how it runs on the tablet if still not good then i will have a go at installing CM10.2
[Nook HD, HD+ Android Development] JanSpatschek:
Good luck.
[Nook HD, HD+ Android Development] Hashcode:
FWIW: It is *NOT* the CM maintainers job to scour the internet and/or monitor other devs work to gather changes and submit them to CM. Though they do it sometimes.

Incoming device changes should be submitted by their respective devs (or on their behalf keeping the authorship intact) via CM gerrit so that they can be tested and approved by the maintainer. <-- that's what the maintainer does.

I have issues with devs using open source projects which represent many hours of development, make some improvements and then not contributing back to the community sources.

Even better, sometimes users reinforce this behavior with comments like "just go use sonso's build" because it has bugfixes, etc.

Get these bugfixes submitted. Then others who work from the same sources can benefit. Everyone wins.
[Nook HD, HD+ Android Development] TeutonJon78:
All very true.

And whole way things have developed with git and gerrit make this actually a possibility, unlike the old ROM kitchen type stuff where people just had it sitting on their own computers only.
[Nook HD, HD+ Android Development] jdjohn:
Good stuff. Since you seem to be in-the-know, could you comment of the validity that milestones (M4 in this case) represent transitional and/or new phases in CM development? In other words, are milestones at the beginning of new phases in CM, or at the end of an existing phase? If at the beginning of a new phase, it would seem that we should avoid flashing those if we are looking for stability. TIA
[Nook HD, HD+ Android Development] Darrian:
They're not milestones, they're monthlies. M4 is not great, I would go with one of the more stable nightlies.
[Nook HD, HD+ Android Development] digixmax:
See http://www.cyanogenmod.org/blog/cm-11-m4-post-release-items for definition of M snapshot releases.

[QUOCM11arrian;51433556]They're not milestones, they're monthlies. M4 is not great, I would go with one of the more stable nightlies.[/QUOTE]

Thanks for straightening me out. I don't want to be posting incorrect information. I flashed Succulent's 3/7 version of CM11 last night, and so far it's the most stable EMMC I have used. I was still getting a few random reboots with the 3/23 nightly. I've only had my Nook a little over a week, but I think Succulent's has been the most responsive and stable ROM for me thus far.
[Nook HD, HD+ Android Development] JanSpatschek:
Glad to hear everything is working.
[Nook HD, HD+ Android Development] Whyzor:
Thanks for clearing this up. Although it would be nice to push changes back upstream, not every dev thinks their fixes are worthy of official inclusion so they may hesitate to do that. By publishing a public repo every dev is implicitly saying "take what I've changed if you like, as long as you credit me." There is also nothing wrong with others help connect the fixes downstream to be picked for inclusion. Working in this industry myself many years I've noticed when both sides wish the other take more initiative, things stall and nothing happens.
[Nook HD, HD+ Android Development] LucaToo:
Slightly off topic I know but has anyone got a link to the free version of Microsoft Office available on the play store as it is incompatible with Nook HD+ ..?
[Nook HD, HD+ Android Development] king200:
http://www.1mobile.com/microsoft-office-mobile-879334.html is the website. I use the "1Mobile Market" app.
[Nook HD, HD+ Android Development] henry8668:
I tried both this one and M4, the ROM itself runs great. However I had issue when restoring App+data from Titanium backup, basically TB just hung on the restore screen forever... Not sure what's wrong, anyone can help shred some light?

Now I restored to my old installation.
[Nook HD, HD+ Android Development] JanSpatschek:
This usually happens if I try to restore an app that is already installed.

Either way just closing TB and restarting the restore while fix the problem.
[Nook HD, HD+ Android Development] henry8668:
Thanks for the advice. The app I tried to restore is not already installed. After reflash the ROM, I only installed TB and then try to restore apps.

Next time I will try this a few times, reboot etc.
[Nook HD, HD+ Android Development] PMikeP:
Why is "camera" in the "next build" list for CM 11 Nightlies?

Dumb question and not important. Just curious. Since we don't have cameras in the HD+, why are there fixes for it in the Ovation Nightlies?
[Nook HD, HD+ Android Development] Whyzor:
Somewhere it's defined to still pick up the camera updates by default even though it's not relevant on this device.
[Nook HD, HD+ Android Development] agantai:
ok here is update: i did not install CM10.2 yet because the tablet with CM11 date 27/03 seems to be good again,i think what fixed the problem was doing factory reset from the tablet's menu settings.

the only problem i have now with CM11 is that titanium backup will not backup app's data. i searched google & found it's something to do with superuser not been compatible. at least my favourite tablet is working fine now. :) i had nexus 7 2013 but sold it because i much prefer the nook hd. :good:
[Nook HD, HD+ Android Development] jdjohn:
You could try MyBackup Root app.
[Nook HD, HD+ Android Development] agantai:
i have already tried the none root version it didn't work,but i will try the root one later & report back. thanks
[Nook HD, HD+ Android Development] JanSpatschek:
Probably because the Camera is part of the Gallery.apk which we can use as a normal Gallery App.

---------- Post added at 07:18 PM ---------- Previous post was at 06:50 PM ----------

I installed 3/27 just out of curiosity and I had no problems restoring my Apps / backing them up. Even data backup works fine.
[Nook HD, HD+ Android Development] agantai:
my backup root same results as all the others,nothing will work with superuser on CM11.

---------- Post added at 05:25 PM ---------- Previous post was at 05:22 PM ----------

well not working for me that's for sure but i can live without this useful feature .i just have to install all of my apps from scratch every time i want to upgrade the OS.
[Nook HD, HD+ Android Development] JanSpatschek:
Did you set your backup folder to the right directory?
[Nook HD, HD+ Android Development] agantai:
i did not,how do i do this ?
