[Nook HD, HD+ Android Development] drmarble:
After seeing some comments about difficulty downloading and installing my zram test build I decided to check.

Box is a bit slow and buggy but it is the only place I currently have to make large files available for others to download. I downloaded the file and the md5 sum is correct: ~/Downloads$ md5sum cm-11-20141010-EXPERIMENTAL-DrM-zram-ovation.zip

df01251818972864611d0eec99e03111 cm-11-20141010-EXPERIMENTAL-DrM-zram-ovation.zip

It should work.

It seems that it is working well for folks. It doesn't seem to break anything. I will recommend that verygreen merge these changes. Maybe they will make it into the nightlies.

Thanks to the 51 folks who downloaded and maybe tested.
[Nook HD, HD+ Android Development] PMikeP:
Cool! Looking forward to it. (No SOD's since your vanilla build.)
[Nook HD, HD+ Android Development] :
Ran with art for a few months and switched back to dalvic last week or so. At least with 4.4.4's unfinished state I've not really noticed any difference as well in the end, though if there is its just slight. Art should help with some hitching though not all. I may need to swap back again to really make sure.

All apps seem to work fine on art here and according to google most should to put it simply, quote "Most existing apps should just work when running with ART. However, some techniques that work on Dalvik do not work on ART." As such my own apps work without any changes.

Out of bandwidth @ Box for the zram build. ?
[Nook HD, HD+ Android Development] JanSpatschek:
Can't download. Out of bandwidth.

[Nook HD, HD+ Android Development] bxlegend:
The answer to this problem would be to get a Box account.
[Nook HD, HD+ Android Development] drmarble:
Sorry about the bandwidth problems on Box. I got a free account with my HP touchpad a couple years ago. I don't have any other place to put it so you can download it. They limit the total download MB for each month. That becomes a problem pretty fast with a full rom. After over 50 downloads that's over 10 GB. Maybe someone could mirror it elsewhere? It was suggested getting your own box account. They have free ones. They never send me any spam email so I can recommend them. That account might let you download it.

Sorry for the inconvenience. I'll try to get it into the nightlies so downloading will no longer be a problem.
[Nook HD, HD+ Android Development] leapinlar:
Did you see my PM? You can get a free account at DevHost (d-h.st).
[Nook HD, HD+ Android Development] drmarble:
Thanks to leapinjar's suggestion I have uploaded the file to dev-host:

Downloading now to check the md5. It is correct so have at it. 600kB/sec download for me.

enjoy.
[Nook HD, HD+ Android Development] Classpro:
tried installing zram rom again. says zip is bad. cwm 6.0.4.6 Any idea what I'm doing wrong?
[Nook HD, HD+ Android Development] drmarble:
I just installed the copy I downloaded from dev-host and installed with cwm 6.0.4.5 (I think I got it from Shumash many months ago). It flashed and installed and booted fine. I think you might be getting a bad download. Check that md5 sum. df01251818972864611d0eec99e03111 I use linux and just type md5sum <file name>. I assume there are utilities for windows or mac that can do the same. Sometimes errors slip into large file downloads.
[Nook HD, HD+ Android Development] PMikeP:
Where is KSM?

So, in the nightly changelog, there is a correction to capitalization for "Kernel Samepage Merging."

Ever looking to eek the most out of the HD+, I don't see KSM in the Performance section of Settings, under the subhead "Memory Management." What's up with that? It used to be there in CM 10.2.1. (Not that I could tell any difference when it was enabled. But who knows? Perhaps it's better now in CM 11?)
[Nook HD, HD+ Android Development] drmarble:
I am making a test build with KSM enabled. I have no idea why it was disabled on our devices. It is enabled on the NookColor and the Amazon tablets with omap processors. Maybe time for another gerrit submission.

Thanks for pointing it out.
[Nook HD, HD+ Android Development] PMikeP:
Cool!

It's kind of fascinating, from a sociological perspective, watching the whole Gerrit build process work. On the one hand, it seems like a pure democracy, where anyone who's competent can vote. (Self-limited in the sense that someone ignorant like me, who doesn't know Linux, can't participate directly in the "government.") On the other hand, it seems like someone somewhere is making key decisions. (As when the decision to force the kernel to run at 100% when running benchmarks was made.) I suppose that ultimately, since it is Cyanogen's ROM, that the folks at Cyanongen make the final decisions. So a benevolent dictatorship?

Anyway, I've wondered before in this forum why the camera apk is in our build, even tho we don't have a camera. (Someone here offered a plausible explanation as to why it's needed. But I always remove it after a flash without problems.) So was the decision not to include KSM purposeful or did it just fall thru the cracks? (Rhetorical.)

Whatever the case, I'm glad to see it might be put in.
[Nook HD, HD+ Android Development] cwmoser:
How did you remove the Camera APK?
[Nook HD, HD+ Android Development] Technosquid:
Just as a bug report, I'll mention that I have two Nook HD+ tablets, one running CM11 M10 and one running CM11 M11, and both reboot after about three seconds of being in flipboard settings.
[Nook HD, HD+ Android Development] jpisini:
Titanium Backup will remove it.
[Nook HD, HD+ Android Development] PMikeP:
jpisini is correct. Titanium Backup will uninstall system apps. I have the free version and just tried it. (I thought that might have been a paid option.)

Heretofore, I've been using Root-App-Delete. When you first try to uninstall a system app with that, it will report that the uninstall was unsuccessful. But then it offers you a workaround, and you just select option 2.

Titanium doesn't go through that routine. It just uninstalls the sys app. Another benefit of Titanium is that it offers to back up the system app for you, so that if you uninstall something you shouldn't have (not that I've ever done that), you can get it back. (Presumably. Haven't tried that aspect of it.)
[Nook HD, HD+ Android Development] dealpapa1:
will nook get cm12 android 5.0? :o
[Nook HD, HD+ Android Development] jpisini:
Too early to tell.
[Nook HD, HD+ Android Development] dealpapa1:
10 more days. lol
[Nook HD, HD+ Android Development] amaces:
Thank you for your builds, [MENTION=4190710]drmarble[/MENTION]; looking forward to the next one. I wanted to add that both the 10/03 and 10/10 snapshots work roughly equally well for me, so I really hope all these patches get merged soon. Sure, there are occasional reboots on both builds, but it recovers quickly, and the overall increase in smoothness is worth it. I am partial to the 10/03 snapshot, although not sure the slightly improved behavior is due to the patches beyond zram, or caused by whatever was merged into CM11 through 10/10.

Now, I know this may be too much to ask, but would it be possible to make your personal builds available as you generate them? It may take a while until all these patches make it into the official nightlies, if they ever will. Of course, it wouldn't be hard to set up a build environment, but I for one am limited by the capacity of my SSD, and it seems like unneeded overhead given that I like (and trust ;) your images.
[Nook HD, HD+ Android Development] PMikeP:
I second a drmarble branch

I was going to ask/suggest this myself after the KSM patch is merged because 1) as a small, ever more obsolete subset of the CM 11 universe, there isn't a lot of pressure for reviewers to act on luxury patches for the Nooks. (I notice there's been zero activity on the zRam patches.) And 2) I noticed one code reviewer wanted to protect us from ourselves in the KSM patch. So we might never get these non-critical patches into the Nightlies.

(I presume the purpose of code review is to ensure the code works. Not to decide for us if we should have the patch or not. (If it's too CPU intensive.))

On the assumption that these performance patches never get in, I too ask if drmarble can occasionally upload his personal builds to his new developer's account, with the understanding that the builds were built for his personal use (and so might have his screen pressure thingie in it) and, therefore, might not be optimal for everyone.
[Nook HD, HD+ Android Development] Darrian:
Just did 2 clean installs (of 10/22 and 10/24) trying to fix an issue I'm having where ~80% of my apps won't download from the Play Store, and I've noticed that systemui crashes on startup every time for no apparent reason. It usually only happens the once, so it's only a minor annoyance.
[Nook HD, HD+ Android Development] PMikeP:
Sounds more like a Play problem than a CM problem.

You said you did a clean install. Does that incluce a /system wipe?

A system wipe wipes out the Play stuff, requirng that you reinstall some form of GAPPS. (Full to Nano.)

I've found an install works best to first install CM, let it boot and stabilize, and then boot to Recovery to flash GAPPS. (Perhaps along with GAPPS-remover to keep out the junk.)
[Nook HD, HD+ Android Development] Darrian:
I know what a clean install is... And I'm not really seeking help with that since I agree, something is going on with Google Play. But yes, I wiped system, data, cache, and dalvik, re-flashed the rom and gapps and set everything up from scratch. I worked around the app issue somewhat by installing the free stuff from 1mobile, but I still can't access most of my paid apps, and I can't download the obb data for large games like The Walking Dead.
[Nook HD, HD+ Android Development] PMikeP:
Please don't take any offense. I assumed you were wanting help, since you posted about a problem.

FWIW, I'm running 10/23 Nightly without any Google Play problems. But all my apps are free. You're giving new info now, that it's your paid apps that are problematic.

The GAPPS guy has archives of old builds. Perhaps you can install a version of Play that worked for you before?
[Nook HD, HD+ Android Development] Darrian:
Well, no, most of my apps are problematic using the Play Store. I had to use a different market to get the free ones. Hopefully it will be resolved soon. I was really just posting about the systemui crash and how I came to discover it. Stating that I did a clean install should prevent people from advising me to do a factory reset to fix it. I just reverted to the latest zram build, again wiping everything, and it is working flawlesly, though the Play Store issue persists.

I hadn't been having any issues with the gapps and it just started doing this a couple days ago. That's why I tried doing a clean install with the latest builds to try to fix it, figuring I had finally updated over old ROMs enough that it broke something.
[Nook HD, HD+ Android Development] drmarble:
ksm has been merged. It will be in nightlies for both ovation and hummingbird.

Enjoy.

Next step, zram. I just don't want to seem pushy. Maybe tomorrow I'll ask verygreen to merge them.
[Nook HD, HD+ Android Development] PMikeP:
Hurray!

I saw your comment in Gerrit about how we xda'ers helped test it. Hurray again!!

Looking forward to zRam in the nightlies. You probably saw this already, but a dev over in the Slimkat thread has built a kernel with your zRam mods. (And gives credit to you.) Triple hurray!!!
[Nook HD, HD+ Android Development] KostasR:
Hi guys. I am running Drmarble's 3/10 version. The redraws of apps are almost gone. My only problem is the occasional reboots. I decided to sell the tablet and and I would like to know which build of CM11 is the most stable of them all. I don't mind redraws or less features. I just want it to work without quirks, bad screen sensitivity and occasional reboots ☺ Any input appreciated. ? cheers
[Nook HD, HD+ Android Development] PMikeP:
You asked wxhich build of CM 11 is the most stable.

I dunno. (The 1026 nightly is running fine for me.) But many will tell you to drop back to CM 10.2.1 if you're looking for a trouble free experience for ungeeky users.
[Nook HD, HD+ Android Development] drmarble:
I sent requests for review to verygreen for the zram patches. There are 10 total and I always feel like I'm spamming someone because he has just received 10 separate emails about this. It makes me feel pushy but that's how gerrit works. He does respond to review requests but he hasn't been spending as much time with his nooks as he used to. I think being a supercomputer design engineer takes a lot of his time.

We'll see if he approves and merges them.
[Nook HD, HD+ Android Development] ejstubbs:
Running CM11 with ART enabled, I've noticed that occasionally if I pull down the notification shade then the screen goes haywire: covered with lines of multicoloured "snow" everywhere apart from the notification shade. IThe screen reverts to normal when I close the notificatin shade. Has anyone else seen this? Nothing seems to crash but it is more than a little disturbing...
[Nook HD, HD+ Android Development] MechaGen:
Try,

System Settings > Developer Options > Disable HW Overlays.

You have to re-check after ever reboot, but worth the effort.

My first almost eMMC failure

I woke up this morning to find my HD+ wouldn't reconnect to the Wi-Fi. That used to happen a lot in previous CM 11 nightlies (say, about two months ago) but I haven't seen that in quite a while now. Anyway, the usual fix was to turn off Wi-Fi and then turn Wi-Fi on.

Turning Wi-Fi off and on didn't work - the HD+ just stalled at the "Turning on Wi-Fi" message. I've had this problem a couple times with recent nightlies and a reboot has always fixed it. So I rebooted.

When I rebooted, my HD+ just stayed at the boot screen. Not good.

I went into TWRP and wiped the /cache. No change. Then I wiped Dalvik. NC. Then I tried "Fix Permissions. NC. Then I decided to look around with File Manager.

There was nothing to see in File Manager! No folders or files showing in the list! (This mysteriously came back later, after I removed and reinstalled the SD card, but I still couldn't boot.) It looked like one of my partitions was hosed with some kind of file system error.

Naturally I hadn't made a nandroid backup since last week. I did restore the /boot partition from that week old backup, but NC. (I didn't think it would fix anything, since I could boot. But I tried anyway.)

Then I made a backup of my current (corrupted?) setup, thinking I might be able to restore that image and fix a file system error. TWRP made the backup but first reported in red letters: "E:\failed to load package". That's probably telling me something.

Instead of restoring from last week's backup, which would have been my fallback plan, I downloaded the latest nightly on another computer and transferred it to the SD card. Then I flashed it.

Fortunately, it appears that my data partition was fine, since the nightly flashed okay. So perhaps /system had been hosed?

I'm hoping this isn't an indicator of failing memory. I'm just now coming up on the end of my one year warranty! This was the nightly with KSM enabled. Can CM 11 itself cause a file system problem?
[Nook HD, HD+ Android Development] TBueno:
I have no idea about what may cause this, but my old SGS also went caput once when running a CM11 nightly.

My case was actually a bit worse, I had to restore stock firmware and start from pre-scratch after a few soft bricks.

After that I kept it on CM10.2.1 stable for a good while until I was ready to flash CM11-M11.

I don't really believe it's related to CM version, but it never happened again on stable/milestone CM.
[Nook HD, HD+ Android Development] Darrian:
Running 10/28 and no more systemui FC on boot
[Nook HD, HD+ Android Development] PMikeP:
It could be the nut behind the wheel.

I flashed the latest nightly today and then watched stuff in catlog.

I kept getting an error with cutilis not being able to write a trace file. So I did what I did last time. In true ignorant hacker fashion (in the old sense of the word) I went into file manager and, without understanding any of the implications, I renamed a library file that went by the name of "libcutils.so" (Or something like that.)

Shortly after that, the wi-fi stopped working, and when I rebooted, -bam - couldn't get past the boot screen.
[Nook HD, HD+ Android Development] cwmoser:
I flashed the 1028 Nightly and my Nook HD+ performed badly - much slower.

Switched back to the 1025 Nightly and my Nook HD+ works great.

Both instances I just wiped both caches.

No idea why -- just my observation.

Carl
[Nook HD, HD+ Android Development] :
The M builds should give you a little more peace of mind. lol
[Nook HD, HD+ Android Development] mr72:
Fwiw I switched to the "M" build when the latest came out, it's been just fine. Waiting now for the next M or an RC. It's nice not to worry about flashing a nightly every couple of days.
[Nook HD, HD+ Android Development] digixmax:
There will not be any RC going forward, as the M snapshots now supplant what used to be called "stable releases" -- see http://www.cyanogenmod.org/blog/cyanogenmod-11-0-m6-release.
[Nook HD, HD+ Android Development] webman2k:
So I mainly use my tablet with the browser, so I thought I'd do a clean install without any gapps, thinking that this would give me some better performance and longer battery life.

I'm using CM 11 M11, and everything is running super. However, I noticed that despite my activating location services, the android browser refuses to see my location. I know this worked perfectly when gapps were installed. I sideloaded Chrome and get the same result. Even though it asks for my permission, and I grant it - no location.

Does android require gapps in order for this to work, or is there something I've missed? All of the setting for location services are on. Thanks for any help you can provide.
[Nook HD, HD+ Android Development] TBueno:
It does. You need Play Services and Google Maps APIs to enjoy Google's geolocation services. I guess you won't be getting push notifications either, since they're usually provided by Google Cloud Messaging services (GCM).

There's a thread on running android without Gapps: http://xdaforums.com/showthread.php?t=1715375

I've thought about trying this too, but apparently it's a lot of trouble.

I hope you can provide us more details about the NookHD+ performance and functionality without Gapps. Is it more or less stable?
[Nook HD, HD+ Android Development] webman2k:
Thanks for the reply. I figured as much. I just found that I'd been doing most of my work in the browser. This certainly wouldn't be for everyone, but it's working for me. It feels... much lighter. Since I'm only really using the browser, it's extremely snappy and hasn't crashed at all. Haven't noticed any weird affects like screen blackouts. Obviously anything relying on google's frameworks won't work, but if you spend most of your time in the browser, you're all set. Think of it as a chrome OS tablet.

I side-loaded chrome since I like it better than stock, and it's great. Google news, search, gmail, even maps (without location) work perfectly right in the browser. My weather site loads faster than the app ever did, same for most of the other google services.

Too soon to tell about the battery life, but I imagine it's vastly improved without all of the Google services running in the background.
[Nook HD, HD+ Android Development] PMikeP:
I need Playstore for what I do, so, unfortunately, I have to let Google in. But I install the Pico version of PA Gapps (I had been saying Nano in previous posts. That was incorrect) and I use gapp remover found on the same xda thread.

Then I use an app called Disable Service to disable a bunch of unneeded (and unwanted) services in Google Play services, Google Play store and Google services framework. (133 out of 191, 13 out of 23 and 10 out of 12, respectively.)

My battery actually increases in voltage when my HD+ is sleeping! (I'd attach a screen shot, but it just came off the charger. Maybe next time.)
[Nook HD, HD+ Android Development] Justintoxicated:
Anyone know if netflix works (without deplayed audio) and if mirracasts work with this build (after using the enabler?)
[Nook HD, HD+ Android Development] simon-edwards:
Hiding my root from Netflix, and restoring later - how?

I'm using CM11 M11 on an HD unit.

After two weeks of tweaking I only have three remaining problems:

In MX Player Pro the hardware decoding appears jittery and is unwatchable on high bitrate hi-res movies. Software decoding is far better. Is hardware video acceleration broken in the CM11 HD kernel? It was working fine on stock.

When using the Nook reading app, if I let the screen go to sleep any attempt to unlock the screen results in a closed screen and I'm back at a blank screen awaiting another unlock attempt. Powering off and on again is the only way back past the lockscreen when it has got into this state.

I have one problem at the moment that I can't easily workaround:

Flixster works fine for streaming and downloads - but only when the device is not rooted. BTW I have nothing to 'cast it too, so I can't directly answer the previous post.

I can't find an app that allows me to hide my device's rooted state from Netflix and restore that root again later. So far I have found several that hide it successfully, but none that restore the root later. I have to keep the initial bootable sdcard handy to re-root the system. Which is a bit of a pain.

If you are doing this hide/un-hide sequence successfully please share how.
[Nook HD, HD+ Android Development] cwmoser:
My Nook HD+ works just fine running Netflix.

Running the latest Nightly, and its rooted.
[Nook HD, HD+ Android Development] jpisini:
There is an exposed module that let's you hide root on a per app level.
[Nook HD, HD+ Android Development] Darrian:
I have had no trouble with Netflix, regardless of root. Still, as jpisini said, there is an xposed module that might be able to hide that you have root. I think it is called rootcloak.
