Backups failing

Hi all,

I run CM10.1 on my phone but am new to the Nook HD+. I have emmc-cwm-early2.1.img dd-ed to an SD card, and it boots just fine. I have cm-10.1-20130719-UNOFFICIAL-ovation-emmc.zip downloaded on the Nook. The problem I'm encountering is that backups are failing with "Can't mount /system!" after boot is backed up. It seems foolish to flash any ROM without an initial nandroid backup.

If I select advanced->show log I see this line:

W: failed to mount /dev/block/mmcblk1p2 (Invalid argument)

However, the Nook boots just fine into my unmodified stock if I remove the SD card.

Help? Thanks!

Candy Crush is smooth for me, but games like Angry Birds are now slow and stuttery. Zombiewood has gotten stuttery as well, Shadowgun though plays smooth.

Hit and miss what plays smooth and what does not. Weird. I guess I need to go back to 7/16 and do a manual adjustment of the dalvik settings. That said, the problems may have existed there too, since did not play many games while had the rom.
[Nook HD, HD+ Android Development] Windsor1959:
Angry Birds, AB Star Wars, Quell and Quell Reflect are all smooth for me. Weirdly, the one game that stutters is the most basic, Homerun Pinball.
[Nook HD, HD+ Android Development] cuoreesitante:
Did a clean install of the 7/19 update (wiped everything, including apps), and the random reboot problem is still here. I'm not sure if it is the Google Maps problem since I didn't even install Google Maps yet after the update.

Also I get stuck at the spinning CM boot logo pretty often. Any ideas what's going on?

On a separate note, are there any other similar but stabl-er roms out there?
[Nook HD, HD+ Android Development] panchokoster:
I have been using this rom for two months and i have never had any random reboot, and i have never got stuck on the bootanimation, i don't know what your problem could be, but this rom IS STABLE.

You should be more thankful for all the hard work and time vg has spent to give us this wonderful rom for free.
[Nook HD, HD+ Android Development] bckrupps:
I have used every version verygreen has come out with and knock on wood never had a random reboot yet
[Nook HD, HD+ Android Development] cuoreesitante:
Get off your high horse. Good for you that you have not had problems. If you dont know what my problem could be, then you don't have anything to contribute. I am not the only person with this issue (along with various other issues). This ROM is stable-enough, but not bug free.

I am thankful for all the hard work vg (and all the other devs that contributed) have put in, but that does not mean I can't bring up issues and problems with the ROM.

Good to hear...maybe I didnt follow the initial setup process to the letter? Seriously considering redoing everything from scratch.
[Nook HD, HD+ Android Development] foolforfood:
I had reboots, but after I installed autokiller and changed the memfree settings to strict I've had no issues whatsoever. Just my experience
[Nook HD, HD+ Android Development] rushless:
The culprit was not the rom, but was the performance settings. 16bit transparency seems to be the issue, and purge assets also impacts some games negatively. Those settings in this rom for most games tested seem to be bad for performance.

GTA Vice City still freezes the device, so something kills it and locks up the device in this rom. I have not tested that game in a few roms, so not sure when it worked last.
[Nook HD, HD+ Android Development] bckrupps:
I always wipe completely and install the next version fresh.
[Nook HD, HD+ Android Development] panchokoster:
[MENTION=3769515]cuoreesitante[/MENTION] Glad to see you edited your post, your initial post was quite aggressive, that is what bugged me. of course you can bring up issues and problems with the ROM.

and yeah, maybe you didn't follow the initial setup process to the letter. Or maybe you flashed the wrong google apps. that doesn't go away with a clean install unless you wipe system manually due to addon.d scripts
[Nook HD, HD+ Android Development] fbueller:
Agreed, 5/11 is still DOA on boot. Dang!
[Nook HD, HD+ Android Development] thegracious:
Dont you connect nook to the pc? It may work! (i hope so)
[Nook HD, HD+ Android Development] Tschumi:
I can confirm that it works. Wiped, flashed, rebooted (with the cable connected) and was able to run the 5/11.
[Nook HD, HD+ Android Development] knownchild:
Why would it matter if it was connected to a pc?
[Nook HD, HD+ Android Development] BigMacca:
Hi Verygreen,

The tethered boot worked for me first time and I can confirm that the case open/close, wake /sleep is also now working correctly :cool:

Awesome work mate

Macca
[Nook HD, HD+ Android Development] sorrowuk:
Is it just the first boot at the moment that has to be tethered to boot up.

Do the next boots after that work untethered ?
[Nook HD, HD+ Android Development] Stevethegreat:
...also has anyone tried the HDMI (MHL) support on the latest CM? One of the reasons I'm still on Hybrid setup (and haven't moved completely to CM) is because now and then I need to mirror stuff to my TV and stock plays that role perfectly...
[Nook HD, HD+ Android Development] verygreen:
That needs some sort of a special cable that I don't have.

Since you obviously have it, can't you try and see if this works in CM? ;)
[Nook HD, HD+ Android Development] Stevethegreat:
I'm on April's CM, if there was any change that has happened since I won't be able to check (May releases do not support Hybrid and for the time being I'm short of time to make a fresh SD setup so that to check this feature ... but I'll definately think about it... thanks for the heads up...)
[Nook HD, HD+ Android Development] jerrycrystal:
No. I can reboot normally afterwards without connecting to a computer.
[Nook HD, HD+ Android Development] leapinlar:
Still running the 5/10 and overnight with wifi on, it had 95% deep sleep.

[Nook HD, HD+ Android Development] verygreen:
Well, while I am investigating this "no boot while untethered" issue, please flash this kernel rollback to 5/5 kernel (same as 5/11, so no functionality is lost): kernel-rollback.zip

Sorry about that
[Nook HD, HD+ Android Development] verygreen:
Thanks for confirmation.

One item off my todo list ;)
[Nook HD, HD+ Android Development] BigMacca:
No need to apologise fella, the amount of updates you have dropped in the last week has been nothing short of phenomenal :good:
[Nook HD, HD+ Android Development] Iggy82:
Just wanted you to know that it also wouldn't boot up until I connected it to my PC, then it was all fine and is now working. Goodbye Nook ROM!
[Nook HD, HD+ Android Development] The Old One:
Could I use your emmc CWM to replace leapinlar's CWM for flashing stock mods?

I don't want to replace nook stock until I can get my UV movies to work in CM.
[Nook HD, HD+ Android Development] leapinlar:
Yes, it works great for that.
[Nook HD, HD+ Android Development] verygreen:
Ok, figured out the non-boot cause.

Updated CWM recovery and TWRP recovery.

Additionally in cwm recovery increased font size.

If you downloaded and flashed emmc recovery prior to this announcement, get a new version and reflash please.
[Nook HD, HD+ Android Development] leapinlar:
Thank you, I tried the new CWM and it is wonderful. And stock users can put this on stock and use it to flash my stock mod zips if they want. But if you get updated to a newer stock ROM, it will replace this CWM with stock recovery. So best to keep your bootable stock CWM SD around in case you need to reflash this one. CM users do not need to worry though, it stays there after a CM10.1 update.

You should be able to do the same with the TWRP version, though I have not tested it.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook HD, HD+ Android Development] dbrickg:
Hurray! Just installed the internal CWM recovery zip and did my first backup with it. Thank you so very much. No more switching cards every time I want to upgrade or do a backup!

One note, the OP says "download the latest binary zip" but points to the 20130510, whereas the changelog shows one from 20130511. I'm assuming you just forgot to update the first link.
[Nook HD, HD+ Android Development] :
Haven't kept up with logging. Will get on that pronto. Need a few days.

Thanks much.

ditto... . . . i go into 'rom manager' and fix permissions - always. . . . i run 'greenify'. . . . . Am running the 'apex' launcher.

. . . . ah, i earned my 'boy scout' badge this morning. when i went out to get the newz paper off the driveway, i noticed an old woman wandering. well, she was my age, OLD but not yet senile... she came over to ask directions on how to get back to the main street. she english was not... the best... i told her i would get a map. i came back with the nook hd+ running google maps. she quickly figured out map pinching and sliding. she got her bearings straight ! ! ! she was a happy camper.

7/19 ROM update for verygreen

I had the performance degradation over time with the 7/16 ROM that was fixed with the stricter dalvik mem settings. I've had 7/19 on for a few days now and it is doing much better. I've had some performance degradation, but nothing like with 7/16. I've also not seen the freezing and rebooting with chrome. It does tend to bog down after flipping through apps, and does seem to get better if left alone for a while, so I can't help but wonder if there are VM settings that could still use tweaking. I seem to have between 75 and 150MB free RAM almost all the time, but I don't have better numbers on the JVM.

I still get the black screen after unlock, and I think I've figured out a pattern. It seems to happen when the tab doesn't wake up after opening the cover. I used to shrug and hit the power button. This will (nearly 100%) result in the black screen after unlock and >50% of the time will not stop unless I close the cover and open it again. I've taken to simply closing the cover and opening again whenever I see that it doesn't wake up, and so far this has prevented the black screen after unlock issue 100% of the time. I believe the issue is the mag sensor putting the tab back to sleep after unlock because it thinks the cover is still closed.

If yer interested, I could disable that behavior and see if the black screen after unlock goes away. so far, I like the feature enough to deal with the mild annoyance.
[Nook HD, HD+ Android Development] mcord11758:
rolled back to 7/12 as it appears for me to be most stable. 7/19 had several reboots but i could not figure out what was causing them and at times I did not even know when they happened. I would come back to my HD after not using it for hours and it would either be booted back up with the wall paper changed or stuck on the boot screen.
[Nook HD, HD+ Android Development] centralpark:
I have been on 7/12 since it came out. On occasion, the recent apps button will lock up and the screen will stay black when I open my cover.

Overall, I am very pleased with this rom. Thanks verygreen for all your hard work!!!
[Nook HD, HD+ Android Development] :
Nevermind... found out it wasn't an issue with the rom right after posting. doh.
[Nook HD, HD+ Android Development] bckrupps:
The 7/19 version for me has been so good that I would actually be scared to try anything else. I did back it up. this is the first time for me anyway that the touchscreen has no sensitivity issues whatsoever. I'm not sure if VG is doing anything between versions with that since he released the screen apk but this build has been 100 percent perfect. each devices seems to react differently to different versions. as I am set up now I think this is as stable if not better than android stock on most units. My girlfriend was given a galaxy s4 phone. first thing she said was my phone lags and your tablet runs better than any android device I ever used. she works for a Samsung kiosk at best buy in Indiana.
[Nook HD, HD+ Android Development] gidal:
It lags badly on mine.

Tried everything from reinstalling app, to erase all and reinstall of ovation zip.

Tried other games as well, and they do the same thing: lag lag baby!

I keep telling myself that I should be happy with the performance I'm getting considering the $150 I spent, but I think I'll have a hard time resisting upgrade to the next Nexus 10 when it comes out.

This is different experience compared to my LG Optimus L9, which was $150 as well, but doesn't make me want to upgrade to better phones (like my spouse's Note II).
[Nook HD, HD+ Android Development] Sherip:
Mine is running great w 7/19 including Angry Birds and other games. I do not allow automatic updates and I am running AdAway. I suspect those are favorable for performance.

Sent from my HD+ Running CM 10.1 from emmc
[Nook HD, HD+ Android Development] ItsDon:
I read somewhere on some forum about the HD+ with cm10.1 that running a live wallpaper helps with the lag. Seems counter intuitive but I tell ya, it does seem to work. I am running 7/19 and am very happy with the performance.
[Nook HD, HD+ Android Development] conan1600:
It does seem to me that when I get a stutter it happens as the processor is ramping up then goes away when it hits max. I wonder if it may be a controller hitch? And running a live wallpaper simply keeps the processor running past the lower MHz.
[Nook HD, HD+ Android Development] gidal:
After reformatting/reinstalling and trying every single options in settings menu, esp. developer and performance, and still no luck with slow down issues.

Then tonight, I undid one mod: Tablet UI.

Ironically, it was reinstalled together with Gapps after reformat.

That did the trick!

Back to happy as a camper now. ;)

PSA: DO NOT INSTALL TABLET UI MOD!
[Nook HD, HD+ Android Development] DeathEvil:
thanks for the heads up, my nook arrives any day now, and first thing i was going to do is cm10.1 with tablet ui :)
[Nook HD, HD+ Android Development] jbbandos:
For me 19/7 also resulted in several reboots and in situations where the walpaper become "square", that is, the top and bottom were black in portrait mode, and had left and right black margins in landscape. Looked like a 4:3 movie in a 16:9 screen.

12/7 worked quite well, probably I'll go back to it soon.
[Nook HD, HD+ Android Development] conan1600:
I have the tablet ui mod flashed and am not experiencing anything untoward. But I'm also not random rebooting like some others. Don't know why. My static wallpaper has got wonky once or twice, nothing to annoying and occasionally a lag. I've noticed the memory manager on this tab is a bit icky and I have questions about the CPU controller in the kernel. I'm sure the good devs will eventually work out the bugs though. Very smart guys.
[Nook HD, HD+ Android Development] rushless:
Given we all have the same hardware and CM 10.1, the main variables are the apps we use and any dev performance settings being used. Case in point, I found that using 16bit transparency, zram and purging assets caused games like Angry Birds to load slow and play stuttery, but some others to not be impacted. Even just having 16bit turned on made AB stuttery.

I think my problem is trying to use this device beyond what I intended: Light gaming, comics, mags, emulators, web, flash and video. Trying to use this like my Excite 7.7 or TF300 for 3D gaming was a bit aggressive. Simply put, the 4470 and 1080p is too much for some 3D games. Not all, but some. Still, the Nook HD+ handles emulators great, since no direct concern of GPU rendering- almost all CPU. The Nook HD+ handles emulators just as well as my S4 with a 600 Snap quad, in spite of the 600 being four times faster in a lot of benchmarks and twice as fast for CPU. I expected MAME to be faster on the S4, but they appear about the same. Same games that are slow on the Nook are also on the S4, S3 and my two Tegra 3 tablets.
[Nook HD, HD+ Android Development] SCWells72:
I saw that the Carbon ROM now includes Voice Plus but the latest CM10.1 does not. Is that expected? Is it easy to remedy? I use Google Voice for free SMS a la iMessage and would love to use the standard Messaging app instead of Voice for that.

---------- Post added at 09:57 AM ---------- Previous post was at 09:41 AM ----------

Oh, one other thing...a bit back I suggested that perhaps a 16-bit color depth might help with the overwhelmed GPU by reducing the data through color depth instead of resolution. I see that some folks have been turning on 16-bit transparency in the Performance settings which may actually help a bit (though some have complained about issues when enabled), but AFAIK, that's definitely no the same thing as 16-bit color depth. After doing a little research, it seems that the color depth is set in the kernel, not in the user space. I did look briefly at the Kernel Tuner app, but it didn't indicate that it could change the color depth on this device.

Has anyone tried a build with 16-bit color to see whether it helps?
[Nook HD, HD+ Android Development] :
Or reverse that - cm10.1 on this tablet - has problems with the apps we use. They all work fine with cm10.1 on my phone which has less ram and storage. Put not even half the apps on here and problems.

I eliminated a few apps and all non-cm widgets but still reboots. If I eliminate much more there will be nothing to do on this thing. But I may try after I get these kmsg errors togther.
[Nook HD, HD+ Android Development] Evanescense:
Could you name a couple of apps that give you problems?

The only problem I have is the wallpaper getting chopped on top and bottom. No lag or restarts whatsoever.
[Nook HD, HD+ Android Development] Azurael:
Considering the fact that the NHD+ has nearly 5 times as many pixels to render as the L9, the same CPU architecture and a lot less than 5 times the memory bandwidth and GPU performance, are you surprised?
[Nook HD, HD+ Android Development] NicoleC:
I'm on the 7/12 build from a 100% clean install and having the same problems, so it's not just you. I only use a few apps and there does not appear to be a pattern to when the crashes happen that I can discern, so it might be a background process.

I'm installing 7/19 and LogCat this evening so perhaps I can provide some relevant information.

Battery Not Charging with 7/19, but fine on 7/12

I have a brand new Nook HD+ (purchased last night). I put 719 on today - using the Nook charger, the LED stays green while the battery doesn't charge. I tried soft resets & reinstalls, different chargers, but nothing worked. Went to 712 package and it's fine now.

With 719, the LED switches back and forth from amber to green during cyanoboot, but as soon as the CM logo starts it stays green. Android reports not charging.

With 712, it goes amber on boot & doesn't change until charged. Android's reporting charging now, at a decent clip.

Apologies if this is already known.
[Nook HD, HD+ Android Development] gidal:
See my update.

Found what was causing the lag.

And BTW, your comment was neither useful nor necessary.

What prompted you to respond in such a way? Did I ever do anything to offend you to deserve such remarks?
[Nook HD, HD+ Android Development] rushless:
Unless referring to another post, it seemed civil to me. :)
[Nook HD, HD+ Android Development] gidal:
I could care less even if it was less civil, but helpful/contributed.
[Nook HD, HD+ Android Development] hyperxguy:
Thanks for the update.

I've been on this ROM for quite awhile. Hardly even remember an issue (well besides the intermittent lock-screen won't unlock, but that could be just a HW issue. I just disable the screen-lock for now). I was on 07/12 without any problem, but just moved to 07/19 just so to see what kinda problems people are talking about. It has been a day and just like before .. no issue here. Thanks for the great work !

I will keep an eye on this 07/19 ROM ... I still have the other five NookHD+s to update, once I'm OK with it (they're still on 0712 and I've not heard any complain from their owners).
[Nook HD, HD+ Android Development] gidal:
Give me a link for the 16-bit kernel, I'll try it out.

16-bit transparency doesn't seem to do anything for me.

Surface improvements with fix banding and blur seems to make launcher smoother, but I'd hate to subjectively benchmark devices.

Synthetic tools like Antutu and Quadrant, on the other hand, don't seem to be affected no matter what settings I messed with. Even when I had Lame TabletUI, they were unaffected (which threw me off, thinking it was the HW)

According to this post here, I should be able to edit the way Quick settings work in CNM 10.1

http://android.stackexchange.com/questions/44788/disable-cyanogen-10-1-notification-drawer-widgets

I cannot seem to to find this option - is it removed by you, or is it something else entirely?

Can I manually enable it, fiddling through the ROMÑ
[Nook HD, HD+ Android Development] spartan4585:
I had the wallpaper getting chopped on top and bottom also and a reboot cleared it up. No issues now.

A faotd from Amazon called "Inverse Universe Room Escape" would not load on the Nook HD+ or Nook tablet saying my device is not supported. I tried the same app on my older TP and it fired up with no issues. Not sure what the issue is. It seems specific to the Nook line.
[Nook HD, HD+ Android Development] :
Don't forget the kmsg logs aftet forced reboot too. I eliminated several more apps and not a single reboot for 25 hours now. See what happens... waiting for one more.

Still working on it - if its not an app or apps will know someday. I don't understand android logs very well so its the long way of test and test some more :) It could just be related and not actually an app - at least that's a theory of mine.
[Nook HD, HD+ Android Development] bxlegend:
The issue is with the the Amazon App Store or the app maker.

I was getting multiple daily reboots too until I uninstalled Google Maps and deleted a google account. I had 2 set up under settings and would get an error about sign in problems then it would reboot.

No reboots since I made those changes
[Nook HD, HD+ Android Development] cuoreesitante:
I was getting reboots AND getting stuck at the spinning CM logo. Then I found out it must have been some app I installed because it only happens when I restore from Titanium Backup, but not a clean fresh install. Also disabled GPS in location services, that probably didnt hurt neither.

Change your build.prop and see what happens.
[Nook HD, HD+ Android Development] deckoff:
No google maps, no reboots. The tablet works best for me on 280 dpi - LCD density. The only thing to sacrifice was dual Columns in play store. Try these out for better performance
[Nook HD, HD+ Android Development] dbrickg:
Curious. I don't have that problem with 7/19, nor have I heard anybody else mention it.
[Nook HD, HD+ Android Development] spartan4585:
I have a feeling this is the main cause of reboots on the Nook HD+. I never experience one reboot on any of verygreen's roms.(knock on wood). It's prob because I never installed or used any of google's apps other than the store. I lead a simple life. lol
[Nook HD, HD+ Android Development] bckrupps:
could be. I have never had a reboot either and no Google maps
[Nook HD, HD+ Android Development] renthispace:
I've never had reboots (all apps stay open in my recent drawer) and I have maps installed and use it occasionally. On the latest 7/19.
