I used a 700kb XVID/MPEG-4 Avi file with .srt subtitles with v 1.7.22 of MX Player. Installed CODEC (ARMv7) NEON 1.7.12. I have use H/W+ Decoder selected for both stream and local checked but I am used a local file for my test.

Version 0117, Unofficial, In settings, developer options, I have "Force GPU rendering" selected. The video ran fine. I believe that the v 1.71 of the player had compatibility problems with CM11. I don't know about later versions.
[Nook HD, HD+ Android Development] NishantM:
I doubt it's the MX Player that's the culprit as reverting to older nightly fixes it. I mean on 10.2.

Sorry for off topic.

Edit: I just flashed cm11 10th Jan build and HW+ decoding works fine with 720p x264 video. Upgrading to the 17th Jan build breaks it again.
[Nook HD, HD+ Android Development] Sherip:
Now running 1/17 update on sdcard with ART runtime and loving it. No glitches so far, and I've used lots of apps and watched some YouTube vids. I also found a hacked Flash player plugin that works in Dolphin browser under KitKat (easily found with Google if anyone needs it).

in case of restarts better geet content of /proc/last_kmsg
[Nook HD, HD+ Android Development] verygreen:
It's possible to do, but I have no installer at this moment.

The easiest you can do at the moment is this:

flash the new cwm image to a spare sdcard, then open it up in your computer, zip the content (all the files you see there) and copy them on the existing sdcard with cm10 install you have (it should have more files, don't delete any of the existing ones, just replae the ones that are present in both images).

Both 0117 and 0118 nightlies lose WiFi passwords at every reboot for me. Previous nightlies didn't have this issue. Anyone else seeing this?

[Nook HD, HD+ Android Development] JanSpatschek:
So what is the difference in updating to the latest Nightly and updating this new unofficial build?

(Thanks for both versions, of course - just curious)
[Nook HD, HD+ Android Development] Classpro:
Bluetooth teathering not working on 1/17 still. It connects but says no Internet in all programs. Any suggestions? It worked inJB.
[Nook HD, HD+ Android Development] Stevethegreat:
I'm on 10/1, dirty flashing this won't downgrade my performance or general experience , right? Thanks, btw., for the continuous support.
[Nook HD, HD+ Android Development] verygreen:
Nightlies run 1 day behind, I think.
[Nook HD, HD+ Android Development] verygreen:
I wonder what's different with your setup, given that there were succesfull tethering reports for cm11 already.
[Nook HD, HD+ Android Development] verygreen:
I am not aware of a single reason why a defradation in performance or experience would happen
[Nook HD, HD+ Android Development] Stevethegreat:
It was often the case that some devs would recommend wiping /data 'fore having their roms flashed. Thanks for your recommendation though it's really helpful...
[Nook HD, HD+ Android Development] Classpro:
I don't know if it's me. Has anyone successfully teathered over bluetooth with this version? Is it possible that there is a setting somewhere to share the internet? I'm using the latest pdanet on the phone and pdanet for tablet on the hd+. They connect fine, but no Internet access on the tablet.
[Nook HD, HD+ Android Development] JanSpatschek:
So does this build have the lag or is it lagfree like 1/10?
[Nook HD, HD+ Android Development] verygreen:
I am not really sure what lag do you refer to, but this has essentially the same kernel as 1/10.
[Nook HD, HD+ Android Development] Sherip:
In settings, I reduce the volume for notifications, but it always reverts to the higher level when I reboot. Also, any idea what wiping is necessary when flashing ROM updates when ART is in use? I've been wiping cache. Rebuilding the cache under ART takes longer than under Dalvik.

Sent from HD+ MAG2GA CM 11 from SD
[Nook HD, HD+ Android Development] JanSpatschek:
Because some said, that 1/10 was snapier than other builds. I flashed 1/18 and just got screen flicker issue. Flicker to black for a second and then back to homescreen.
[Nook HD, HD+ Android Development] dbrickg:
I've been wondering the same thing. I always wipe cache and dalvik cache, even though I'm not sure there is such a thing as a dalvik cache when you're using ART. And, yes, it takes a LOT longer to rebuild the cache with ART. It's my understanding that that's because it's doing a LOT more work, essentially rebuilding each app into machine language, which is its advantage.
[Nook HD, HD+ Android Development] yhli17:
I am on Jan 17. Smooth like butter. MX Player handles 720p DTS through net (ftp) without issue. Will stay with it if the only enhancement of Jan 18 is 1080p playback. I wiped system, cache, and dalvik before flash.
[Nook HD, HD+ Android Development] JanSpatschek:
Thanks. No screen flicker on 1/17? And could you explain what you mean with "handels 720 p DTS through ftp".
[Nook HD, HD+ Android Development] yhli17:
No single issue so far. From ES filemanager, open video on the ftp server with MX Player.
[Nook HD, HD+ Android Development] Chomanator:
Yes, I am experiencing this issue as well.
[Nook HD, HD+ Android Development] YOUCANNOTDENY:
Just a few testing updates:

I just ran SunSpider, and my Nook HD+ completed the test in 903 ms which is, quite frankly, amazing.

I, too, noticed the UI performance degradation upgrading from the 1/10 build to the 1/17 nightly. The concrete evidence for me was the extreme frame drop when scrolling through my apps with the stock launcher under the 1/17 nightly, which was not present under the 1/10 build. I can confirm that these performance issues have been completely fixed in the 1/18 unofficial build (not nightly).

Thanks, green! Just wondering, what was the culprit?

Lastly, I have a few bugs to report. Two can be seen in the attached screenshot.

1. This is pretty minor, but the "back" button is a different shade of white from the "home" and "task switcher" buttons. It appears that it has been dimmed while the other on-screen buttons have not. The screenshot shows exactly what I'm talking about. If I recall correctly, this bug was present in every CM11 ROM I installed on my Nook HD+, so this might be a CM issue.

2. Any shortcut placed in the bottom right corner of the homescreen disappears upon reboot. This can be seen in the attached screenshot: there was a shortcut for a file manager in the bottom right, but it disappeared after a reboot. I also remember that this bug was in every CM11 ROM I installed on my Nook HD+.

3. After rebooting (leaving WiFi enabled), my Nook HD+ refuses to reconnect to a saved network. Under WiFi Settings, it shows as "disabled" under the saved network. Then, after a while, it forgets the network, and I can reconnect by entering my password again. Strange...
[Nook HD, HD+ Android Development] jbbandos:
This is exactly what I have been seeing with nightlies since 16/01, and now with the 18/01 unofficial. Previous nightlies and unofficial didn't show this behaviour.

I hadn't noticed the "disabled" period until now, as I hadn't used the tab for some time after each reboot, but saw that now after installing the 18/01 unofficial. I even tried enabling the saved network, but it didn't connect, only after some time it forgot the network and then I was able to enter the password and connect again.
[Nook HD, HD+ Android Development] asawi:
I don't use stock launcher so I don't know about no 2 in the above post, but I know for sure I don't have bugs 1 or 3 on my HD+ running 0118. I'm not on ART if that matters.
[Nook HD, HD+ Android Development] mpeg3s:
hybrid

Is this a hybrid install duel os boot or stock overwrite?

Having many issues with the sdcard only ver, but it may be cm 11.

Thanks!
[Nook HD, HD+ Android Development] asawi:
I am running stock overwrite. Works fantastic on both HD+ and HD!
[Nook HD, HD+ Android Development] brentil:
I have the random screen blackout too. I haven't had it enough though to notice any possible cause. I'm on a HD+ running stock OS features (no replacement launcher, no kernels, no patches) and I'm using one of the background images that games with the ROM. I noticed it with live desktops too. I noticed it in CM11 official & unofficial builds.

Well, you could help the man find the culprit by sending him your last_kmsg!!!
[Nook HD, HD+ Android Development] jpisini:
Not sure what to do no matter which version I use I get the sleep of death. It is only CM11 both 10.1, 10.2, work fine. No issues with stock or Carbon either.

How do I do that
[Nook HD, HD+ Android Development] RYARNI:
There really is no need for the exclamation marks. Try to be more helpful, if you know then you wouldn't just be helping 1 person. If its already in the topic then inform.

Really liking the rom/ although still on 10/01 as I don't want to experience the issues since. I do wonder if these are hardware faults coming out..
[Nook HD, HD+ Android Development] Jann F:
Ok, I only experienced it that much on unofficial build 17/1 and I have gone back to 13/1 because my tablet was beraly unusable.

Do you still need the kmsg or is the problem solved already?

I've found out that it mainly happened when an overlay app like fb messenger was layed over the homescreen or an app and it happened once while the downloads overlay was open.
[Nook HD, HD+ Android Development] jwats1973:
First off, Thanks a TON verygreen for putting this together. I was hoping to download the nook reader software from the playstore but it says it is not compatible. Is there anyway to sideload this apk?
[Nook HD, HD+ Android Development] leapinlar:
Yes, get it from 1mobile.com.
[Nook HD, HD+ Android Development] felacio:
Wasn't able to pull a kmsg or last_kmsg, the latter didn't exist and the kmsg kept getting stuck when trying to copy it.

But I too am still getting the screen flicker. It will show the screen, black out as if it's showing a black screen with the backlight still on and everything and then blink in the homescreen again. closing case a few times didn't fix it and turning screen on and off didn't clear it up using power button, only thing that fixed it was a reboot.

I was also getting the "WiFi forgot hotspot password" but 01/18 seems to have cleared that up as of right now.

Still really loving this ROM though and wouldn't think of switching back even with these bugs. I'll keep trying to pull the kmsg unless that isn't needed.
[Nook HD, HD+ Android Development] verygreen:
/proc/last_kmsg file is only available after you had a sudden reboot (usually an indication of a kernel crash)
[Nook HD, HD+ Android Development] verygreen:
Hm, this one seems like a bug inside of the sgx firmware (for gpu) where it first locked up and then it failed to restart when kicked by the driver.

I have no capacity to overcome this as the sgx part is closed sourced and we only get binaries. Also given that it's a somewhat rarely reported issue (you are the only one and I also saw one more report about just failing to wake up), I wonder if it's some more marginal hardware starts to show itself?
[Nook HD, HD+ Android Development] Jann F:
[MENTION=3654172]verygreen[/MENTION]

At that time I was at official nightly 1/13 today.

Sorry for double post, the first zip file with last_kmsg was corrupted and I can't delete post.
[Nook HD, HD+ Android Development] verygreen:
Both of these are also a failure to initialize/bring back to life the gpu after lost sync.

I am not really sure why this started to happen all of a sudden, esp. since nothing of substance has changed in the gfx drivers.
[Nook HD, HD+ Android Development] JanSpatschek:
So if it's not the gfx driver, what is the culprit? unfortunately I don't know much about developing, so I can't help ...

Hard reset before update

I hard-reset before I installed 01/18, having been on 01/10 (which was ok) & 01/17 (which gave problems) - so far, wi-fi behaves well and no screen flashing issues... touch wood.
[Nook HD, HD+ Android Development] jpisini:
Clean install did not help me.
[Nook HD, HD+ Android Development] metropolitans:
I updated to the 1-19 nightly for the HD yesterday and was extremely happy to see that the local user profile image was restored to the "User switcher" tile in the notification drawer. I know it's just a GUI thing, but I really didn't like having my Google+ avatar in there. So thanks for that!

I just got my first spontaneous reboot ever (on any ROM) yesterday while granting superuser privileges to Battery Doctor to prevent autostart for some apps. But I haven't had any since. Also, on one of the nightlies a few days ago, wi-fi once reconnected after sleep to a neighbor's network, instead of mine. But that hasn't been repeated since then. Other than those 2 minor things, performance with CM 11 has been rock solid and stable.

There is one thing -- Battery drain seems to be slightly higher with CM 11 than on stock, but only while in actual use. While sleeping, it's actually a little better, getting 0-1% battery drain overnight.
[Nook HD, HD+ Android Development] jbbandos:
Forget it, the wifi is still losing the configuration after each reboot. It is almost like wpa_supplicant wasn't opening the conf file.
[Nook HD, HD+ Android Development] bykim5:
Installed 1/19 nightly last night. Wifi was logged out when i turned it on from sleep. Toggling wifi didnt fix it, had to manually reconnect
[Nook HD, HD+ Android Development] bpaulien:
That's so weird. I've never had any issues with Wi-Fi on CM11 so far. Including the 01-19 official build. It just jumps right in with access whenever I need it. No need to reset anything. I have the 'Wi-Fi on during sleep' set to only when plugged in. And whether it's plugged in or not, it never has a problem connecting.
[Nook HD, HD+ Android Development] chn110:
1/18 build is very smooth. One issue with 1080p video playback. I used to be able to record 1080p video using camcorder onto a MicroSD card, and then plug the card into Nook HD+ and play back using VPlayer with HW decoder enabled. This worked beautifully with the Stock ROM. In 1/18 Vplayer can only play with HW decoder disabled and the video will stutter. It crashes if enabled.

[Nook HD, HD+ Android Development] js365:
With 1/21 for around 3 hours. Screen flickering still there. Haven't experienced any random reboot.... yet....

---------- Post added at 12:13 PM ---------- Previous post was at 12:10 PM ----------

I'm not sure about the 1080p issue. I tried 720p only. MX player with H/W decoder enabled. It works smoothly. 1/21 build here.
[Nook HD, HD+ Android Development] bxlegend:
There were no device specific changes in the latest nightly. Therefore, the same issues will still exist.
[Nook HD, HD+ Android Development] bpaulien:
Ok. I think I have finally figured out what is going on. Notice that I didn't say I know why, but what. First for those of you who are having the Wi-Fi issues, are you running on dalvik or ART? I don't know why, but I think it makes a difference. I've been running on ART for the last few days, and haven't experienced any problems with Wi-Fi.

Today, for kicks I decided to go back to dalvik, just to see if I could notice anything different. Well, the first thing I noticed was that my Wi-Fi wasn't working. I couldn't even start it by deactivate it and reactivate it, or by turning on airplane mode and back off. So I went to Wi-Fi settings and had to enter in my password. Which is exactly the problem others have been complaining about.

I thought, there's no way that could be the difference, there must be something different in this build. So to test, I decided to go back TO ART and after the reboot happened, I had instant access to Wi-Fi.

So it's my theory that SOMEHOW ART is remembering the Wi-Fi password, but dalvik isn't. Hope this helps.
[Nook HD, HD+ Android Development] JanSpatschek:
Good point! I am running Dalvik and just experienced a random reboot on 1/21 Nightly and the Wi-Fi issue. Strange.
[Nook HD, HD+ Android Development] MechaGen:
I've been on dalvik from the start (never tried ART, can't give up Xposed) and have no problems at all with Wi-Fi on 1/17 UNOFFICIAL. On 1/10 I did have to turn Wi-Fi off and back on after sleep.
[Nook HD, HD+ Android Development] rhyang:
1/18 unofficial or nightly ? The 1080p fix probably didn't make in until the 1/19 nightly.
[Nook HD, HD+ Android Development] bpaulien:
I've only heard of Xposed, never used, or read what it can do, really (or how to install it). So I guess I don't know what I am missing. Might give it a try some time. if I'm not too lazy!
[Nook HD, HD+ Android Development] verygreen:
I run my own builds (and ocasionally nightlies) and I have zero wifi problems. Did not get around to trying ART, so 100% davlik.
[Nook HD, HD+ Android Development] succulent:
I myself have no Wi-Fi problems on my build with TI WPA _SUPPLICANT. I think it might depend on the user's router/modem/security.

However, webdroidmt uses my build and have Wi-Fi problem. He replaced the wpa_supplicant.conf from the TI WPA_SUPPLICANT with non TI WPA_SUPPLICANT and it fixes it for him. Maybe someone here should test it out to see if it fixes the Wi-Fi problem for them.

All they have to do is edit the content inside /system/etc/wifi/wpa_supplicant.conf

1/19 still broken for Vplayer with HW decode.
[Nook HD, HD+ Android Development] victle:
I have HD 1080p movies stutter problem on 1/17 build, the 1/18 one did fix it for me. Mine is HD+ using Archos player (the best video player, plays everything I throwed at it including 1080p)
[Nook HD, HD+ Android Development] Darrian:
I love vplayer, but I had to abandon it months ago because it wouldn't reliably play back videos without slowdown or stuttering and sometimes it couldn't play them at all. It sorely needs updating. In the meantime I have been using archos and mx player. Both work really well.
[Nook HD, HD+ Android Development] jbbandos:
I've decided to track which change breaks remembering wifi connections for me, and managed to narrow it down to the line "config_methods=physical_display virtual_push_button keypad". If I take that single line out of wpa_supplicant.conf I have no more issues, at least with the work 802.1x EAP (TLS) network. I have yet to see if this line is essential for WPS pairing.
[Nook HD, HD+ Android Development] metropolitans:
I've had no problems with wi-fi turning off and on when the screen turned off and on using both official and unofficial CM 11 builds on my HD. However, I've been using Llama to do it.

Today as a test I turned Llama off, and under "Keep wi-fi on during sleep" I checked Never. The problem I am seeing is that wi-fi won't turn off when the screen turns off. I double checked in my router's setting and the HD is staying connected. Is there another setting that has to be set?

I've turned Llama back on. Llama is 100% reliable for me, and so I have no problem using if forever. But it would be nice if I could also get the native function working.
[Nook HD, HD+ Android Development] chn110:
In 1/19 build MX Player plays 1080p .mts no problem. Archos can't handle AC3 audio. Vplayer stutters. So looks like apps issue not the build.
[Nook HD, HD+ Android Development] Darrian:
Actually I think if you install the free archos codecs pack it will handle ac3, but I still prefer mx player anyway. What I love about archos is the media library layout and the ability to see network shares; I wish mx player could incorporate some of those features, then I would use it exclusively.

[MENTION=3654172]verygreen[/MENTION]

I have been using succulent's CM11 build and I haven't experienced any reboots, black screen issues or Wifi problems. But your build is much faster and snapier. Maybe you could check with him and find out why his builds don't have the issues and implanted into your ROM?

Anyway, thanks a lot for all the work you have done so far!
[Nook HD, HD+ Android Development] dcahoe:
I'm not on the latest CM11 nightly (I'm on 0118) so this might not mean much, but whenever I wake up my HD+ with the power button I hear an audio pop or crackle. It is just for an extremely short instant. I usually have my volume turned off so didn't notice this before, but it only does it if my volume is not off. I didn't have it turned up all the way either, just somewhere mid-range. I saw an earlier post where someone was getting an audio pop with an immediate reboot, this is not happening to me, just an audio pop, I have had no lockups, crashes or reboots at all with CM11. It works great.

Also, I have had no screen flashes with CM11 but this seems oddly familiar. I have 2 HD+ nooks and one of them had screen flicker months ago right after I rooted it and put CM10.1 on it. I think it was on my wife's nook and was annoying her enough she didn't know if she liked the nook or not, but luckily it went away, probably with a new nightly ROM and she has loved it ever since. Now, her nook is still on 10.2 because I have been waiting for CM11 to get a little more stable (I don't like to mess with her working setup).
