CM7 boot looping

Can anyone give me a hand with this?
I was running CM7 n40 with ALSA and dalingrin's 0413a kernel. Watching videos in vevo when the nook froze and reset itself and got stuck looping at the CM7 animation.
I've rebooted into CWR, tried first wiping Dalvik cache, it didn't seem to make a difference. I then tried formatting /cache and reinstalling n40 and dalingrin's 0404 kernel. No joy either.
Short of reinstalling everything, is there anything else I can try?

If you are running from an SD card then your problem is likely the card. If you aren't running from an SD card then... Maybe someone else can help you.

Forgot to add, running from eMMC.

I had the same thing, only with CM stable...ended up having to rebuild my / boot with the file here.... http://forum.xda-developers.com/showthread.php?t=914690.
Very last file in first post. Had to flash it then start all over....

You are not alone, mine just did this after updating to the latest nightly and restoring with Titanium Backup. I did not flash a kernel, just the nightly using Rom Manager.
My symptoms were that it seemed to run OK, then I opened the gallery to set a different wallpaper and got constant FCs, so then I restarted. Now I'm watching the circle go round and round.
OK, back to previous, just restored the nandroid backup Rom Manager made prior to the update. Seems to be working fine.

I flashed n40 and dalingrin's oc kernel 0404. Stable and happy as can be.
I'm thinking the issue was with ALSA and experimental kernel 0413a, which has been reported to crash video playback in some cases. Don't know how or why it would corrupt my install though.

Let me just mention a lot of people are claiming false boot loops lately. Sometimes it just takes a long time to reboot, especially after it froze. I've had it take up to 20mins before with the little skateboard android.
So next time unless it's giving you "Touch The Future" and then the CWM treatment, give it a bit to load and see if it does after 10 mins or so. (Usually just after the screen dims, my nook loads up just fine)

No that's unacceptable. Considering the amount of data it should be loading, something is very wrong with your nook if it takes more than 5 minutes to boot.
And yes it was boot looping, the animation restarted itself repeatedly (wasn't just the arrow spinning).

Can't help at all but to offer another data point: I was on nightly 39, ALSA update, and kernel 0413a. Was flicking between homescreens when it locked up, forcing a hard shutdown. When I booted back up, it was stuck in a bootloop. Tried all the usual paths to recovery, but had to resort to a backup.

Moved on to n41 (ALSA included) and kernel 0418c. Stable in every case so far.

I'm having same issue and mine is still not working no matter what I did.
I even tried to restore it back to stock - Format/ Fdisk / DD / etc... tried everything I could find. I even had my back up but couldn't restore. I think I created more problem while I was trying to fix it.
Now I can only boot from SD. So I was not the only one.

Eww, I would never touch any sort of partition change with eMMC installs. Usually I just go back to stock or latest backup. Found out there may be an issue with backups created from CWR flashed to eMMC (MD5 check failure). SO anyone who's made a backp from that, do yourself a favor and boot off a CWR SD and do a backup onto that just to be safe.
Sorry about your troubles, hope you get it sorted. Guess I got away easy with just format and nightly re-flash.

Can't boot from stock internal eMMC

On my eMMC I have a stock Nook Color OS which is rooted. Worked great for quite a while. Last night I force shut it down (held the power button for 10 seconds).
Today I'm trying to boot it back up and it won't boot. I see the "Reading Forever" logo, then the "Nook Color" logo (believe from the rooting) comes up. That logo animates once, then it repeats, but stops at "Nook Co" stops, and the just keeps looping like that forever. Never finishes booting up.
Now I can boot up with my CWR SD card and also from my CM7 SD card. I'm hoping there might be some easy fix to be able to boot my stock rooted image again without having to wipe it out and starting over. Should I clear some cache or some other idea?
Thanks.
Update: I decided to just go ahead and blow way the install and do a factory wipe and reload and reroot it again. After I did this, I started wondering, I had Nook OS 1.2 installed and rooted. I wonder if 1.3 might have automatically installed on me and blown up because of the root? *shrug* Well, don't matter now. I started over.

Wow... after wiping it and starting over. It happened again.
Everything was going well. Rooted successfully, Market mostly working, installed a few apps. Rebooted a few times without issue. Then I noticed some apps were missing from the Market that should be there (no ADW.Launcher) so I was doing the normal Market fix. Shut down. Powered up, now it's hanging again on that "Nook Color" animated logo.
Argh! Maybe it's a sign I need a Kindle Fire. Haha.

Did another factor wipe. Rooted it again. All going well. And finally once again tried to do the Market fix. Cleared the Market cache, cleared the Framework data. Powered off. And again it won't boot back up.
This is so weird. I've done that millions of times before without issue.

Curious. Tried again after another factory wipe. And this time I decided to not bother with the Market app. All is going well. Until I reboot after the newest Market (with the music section) installs. It's all fubar again.
Could be the reason it blew up in the first place too. Hmm... Wondering if anyone has been able to reboot their rooted Nook Color since getting this new Market without issue?

Search the forums, there is a thread on this issue, you have to keep it from updating Adobe flash I think. I had this problem too, but haven't had time to root again and check for myself.

The issue I'm having definitely seems to have the exact same symptoms those with the Flash Player issue are having.
But I never installed or updated Flash, manually anyway. And I installed the Flash Player fix and it still didn't fix my boot up problem. Bummer, thought it was going to be it.
I think I'll do another factory wipe, go through the process again. And when I see the Market update (kinda still my only suspect at the moment), I'll go in and uninstall that update and reboot and see what happens.

It's the Adobe AIR update. Argh.
I had gone through my factor wipe/root process again, I immediately uninstalled the Market update as soon as it came. Also looked for Flash Player and it isn't installed. Rebooted and it still blew up.
So I went through the start over process again. And since an Adobe Flash Player updated caused problems similar to mine and while I don't have Flash, I do have Adobe AIR and it happens to be updating after I run Market. So this time I was able to cancel that Adobe AIR update. Rebooted. And it is still working.
Apparently that Flash Player Fix tool doesn't seem to work with Adobe AIR and that update is breaking my Nook Color.

[Q] NOOK HD+ with cm-10.1-emmc hangs on CyanogenMod log.

Hi guys,
I just got two HD+ 32GB and installed cm-10.1-20130527-UNOFFICIAL-ovation-emmc following evergreen and leapinlar's instructions. The installation went well, and I can boot the tablets into twrp recovery. But I cannot boot one tablet into Android. It always hangs on CyanogenMod log (the rotating circle/wheel with CyanogenMod text at the center) when trying to boot into Android. I reboot the tablet several times now and still have the same issue.
I repeated the same procedure on another Nook HD+ 32GB and I can boot the second tablet into Android after several reboots. But I still have no luck with the first tablet.
Any suggestion?
Thanks a lot for the help!

I installed CM10.1 eMMC on my HD+ for the first time last night and the same thing happened to me. So I went back into recovery and installed the CM10.1 again and then it booted up normally afterwards. So in my case at least it seems like it didn't install right on the first try.

Thanks a lot for the suggestion. I finally got It to work by booting into TWRP to wipe system, data, and caches, then re-installing from zips.

Same issue, apparently (hopefully...) resolved
LIke many other posters here and elsewhere, I installed CM 10.1 on my brand new Nook HD+ 32gb, got it to boot into CWM after many trials and tribulations (I had to reboot about 30 times to get the device to boot into recovery from SD; it crashed halfway through backup in spectacularly frustrating fashion, and it took me about 30 more hard resets to get it to boot into CWM again. I used a brand new Amazon Basics 32gb class 10 card). I did a little victory dance, loaded up some apps (probably too aggressively: 50 or 60 of them), rebooted, and.... you know what happened then, or you wouldn't be reading this (probably whilst sweating and/or crying).
After uninstalling some resource-intensive apps, then booting into recovery and wiping both caches, I was able to reboot normally (aside from waiting a couple of minutes for apps to be "updated" or "optimized" or whatever), but the next and all subsequent reboots failed unless I first booted into recovery and wiped the caches.
Finally, after reading a number of posters with the same problem (including @Ravynmagi and @sean_nj here--thanks, guys), I took a deep breath, did a full Titanium backup, booted into CWM, did a factory data reset, and reinstalled the three zips from the bootable SD. CM booted quickly and normally. I rebooted a couple of times with no problems. I installed a few apps, rebooted normally. I installed a few more apps (including a couple which I sideloaded), again rebooted normally. In the last 18 hours, I've installed a few more apps, played some resource-intensive games, tested Netflix and a sideloaded video, etc.
As of now, the device works like a charm and boots quickly and without drama. If anything changes (and I'm still able to communicate like a civilized human being), I'll make sure to update here.

unable to reboot get spinning logo
I recently updated Nook HD+ to 10.1 w/o problems.Each time I have rebooted it take 2 -3 tries before it finally boots ups. Those other times if boots to the spinning Cyanogen logo. Is there something I can do to check with the system booted up correctly to figure out the problem. If not, what steps should I take now and how do you do a complete backup of all the newly added material since the initial update. Thanks again,
Al

I'm facing the same problems but with a different setup: latest CM 10.2 Carbon ROM release (both versions with and without multiwindow). I have random bootloops and I'm unable to track down the problem.
Are we the only users with those bootloops?

Was searching for this. I am not having a problem booting per se, but all of a sudden I am getting a weird booting thing. Where the logo comes up and spins but its distorted, then it becomes normal looking, then my Nook will kind of reboot. Not a complete reboot just the screen goes black for a millisecond and then the logo starts over again where its all distorted, then it goes normal and then it boots.
I guess you can call it a logo boot loop. The thing is, it doesn't happen all he time, just most of the time now. When it happens, my SD card is incorrectly mounted and I have to umount it and take it out physically and re-insert it.
Nook HD+ 32gb, CM 10.1.3 stable and mbg4ga emmc. Not sure if this is the same as you guys but it sounds related. I've re-flashed several times. I think if you guys can find a cure, then it would probably work for me as well. Quick question, any of you guys using auto-patcher to patch Pdroid? How about Xposed?

For getting caught in the boot loop try:
Settings>Launcher>uncheck wallpaper quick render.
This is for stock Trebuchet 1.0 Launcher. I hope the developers are aware of this.
Probably coincidental but, the glitch caused by the magnetic closure on my case much better.(when you try to unlock and it blinks and goes back to lock).
Good luck.

[Q] Nook HD+ CM10.1 Boot Loop

Hello,
Earlier today i successfully installed CM10.1 on my new Nook HD+ tablet. After setting up CM10.1 and installing some basic apps i restarted the Nook and it is now stuck in a loop at the Cyanogenmod start up screen. Any suggestions on how to fix this?
Thanks guys!

I had this same issue. I made a titanium backup of everything, and then reinstalled cwm, cm 10.1, and emmc ovation. I used titanium to restore and now it resets just fine.

Same here...
I had the same issue. I went in and cleared the cache then reboot and it was fine. My issue now is it'll randomly reboot on its own and sit at the Cyanogen circle boot up but won't boot up. Anyone else?

I booted into recovery and wiped dalvik cache and the othe cache and it booted fin out of recovery but when i would attempt to reboot it normally it would still be stuck in a boot loop...I just factory reset it and it seems to be working fine now *fingers crossed*!

still no go...
I tried that too and it still reboot randomly. Thought that was fixed with latest version

I had the same problem. This is what I did. In the recovery menu I did a wipe / factory reset. Then installed CM and Google apps again. After that I did another wipe / factory reset. After that I rebooted. No more random reboots and no more boot loops. I hope this helps.

trouble restart
Just got a Nook HD+ on the 26. installed CM10.1. every time I turn off or restart the Nook, For the first 3 times, it would stuck at the fast spinning CM logo. I would have to long press the Power button to turn it off, then turn it back on. For the 4th time it would boot without any problem. same thing with boot into recovery, the first 3 times it would ignore my N+down press, only on the 4th attempt. Not sure why, but that's what I found out. I dont see any random reboot yet. Have not try to reinstall CM10.1. Will do that when I have more time. Anyone else with a newly bought Nook care to sound in?

Very similar problems for me, though I don't know if it's exactly every fourth time that it boots properly.
I did a factory reset, re-flashed everything, and it worked perfectly for a couple of days. Then yesterday, a random reboot, and it got stuck at the CM boot animation. It rebooted properly on the second or third try. I just rebooted it manually, and it worked fine again.
I really like this tablet, but I'm seriously thinking of returning it because of this problem. It seems like it could become completely unusable if it gets worse.

CM 10.1 Boot Loop CWM non responsive
I have the same issue. I used powered up and used Volume Down>Menu and it rebooted my Nook HD+ to back to the original Nook OS. Weird because when installed I deleted factory defaults like the instructions said before flashing. Anyway, now when I hold volume down>Menu on boot it come up Black screen with warning telling me it will delete all my documents and reset to factory. Will this wipe the CM 10.1 OS totally? Is there a way for me to get my CM 10.1 back without going through and making a boot image again and reinstalling from starch? CWM dose not seem to be working or am I using the wrong method to booth into CWM on my Nook HD+?

What you are seeing is stock recovery (I assume you mean you held n and power on boot, there is no menu button). You must not have successfully flashed the CWM or TWRP recovery to internal memory. That reset to factory it will just wipe your data, not remove the ROM. It will cause you to reinstall your apps though.
If you ever intend on updating your CM10.1 to a newer version in the future, you need to have that bootable recovery SD anyway (or successfully put it on internal memory).

In did install both the CWM and CM 10.1 the first time. It booted and rebooted for days without a problem. I believe b what happened was error. I had the alarm set to wake me and half asleep tried to turn it off while the groovy cover was shut by holding down the power button. I may have held down more keys then I thought in a sequence that deleted something that caused the Boot to hang. After that there was no way for me to enter the CWM. The command sequence that would normally send me to CWM sent me to nook factory reset. I noticed that there is a small glitch between hibernate and the b alarm. Holding down the power key to get it to shutdown can cause it enter CWM from time to time.
When I reinstalled everything funny thing is my screen lock settings and background selection (I previously downloaded) stayed along with my user profile. That leads me to believe that everything was in tact on the internal storage. Google play backed up and reinstalled all my apps automatically once I signed in:good:. I'm taking your advice and buying a 4G SD to keep the CMW boot image on with the latest CM. Thanks for your help.

Distorted Boot Animation
Is there a way to fix the distorted boot animation on Nook HD+ CM10.1? I have tried installing a different bootanimation.zip but it didn't make a difference.
I found this post on a similar problem with the nook color running CM10.1, and steven676 fixed the boot animation issue with a new kernel. "I was wandering if it could be used to fix the Nook HD+ as well?"

Yes that could fix it, but it messes up other things. Best to just live with the distortion.

"I guess in order for one to gain, one must lose something." LOL
In meantime I'll just disable the boot animation with Rom Toolbox.
Hopefully it get's fixed in later updates without any lost.

This thread seems to be in the range of what my issues are. The Nook worked fine for about 4 days and then while installing the Retro Arc apk I sideloaded, it picked up on an unprotected Wifi connection in the area. It then locked up as the notifications were flying in, and the screen went black. I powered off then off after that once and the Cyanogen logo just kept looking. Tried again after and it went to Stock Nook.
The last few days have been spent doing clean installs with care taken to follow the exact steps, but now all I get for 2 days is the Cyanogen Logo looping over and over. Help?

Just found this on a thread here. I can't find it at this time. I would really like to credit and thank the poster. I had to go into CWM and wipe dalvick cache on every boot. I have only booted once but this change seems to have fixed this issue.
Firsts go into CWM and wipe dalvick cache.( Hold down the power and n buttons until you get into CWM. Go to advanced and wipe dalvick cache. Reboot)
When you get it booted, go into setting/launcher/home screen and uncheck Wallpaper quick render.
Good luck!

Edit to say credit goes to Arron Camp for this fix. Thanks Arron!

I have had the same problem in this thread as well (reboots stuck at cyanogenmod logo). I have been wiping the dalvik cache every time (figured it out on my own) and can confirm it works but you do have to do it at every boot (or perhaps after you change wallpaper, not sure).
I got tired of it happening so i google'd the issue and found this thread; mine is stuck right now too (and also out of battery, lol), but once I charge it, wipe dalvik and boot into android I will try the "quick render" trick and see if that fixes the boot problem to begin with.
Edit: I can confirm that disabling quick render has fixed the need to do a dalvik wipe every reboot.

I don't know if the color+ has sdcard recovery but if it does that would be the way to go except for...
The other thing is that if you had put on a custom recovery then holding what ever buttons to go to it could allow you to fix it. Or waiting until 8 reboots or whatever if its the same as the nook hd+.
I think there may also be additional stuff that can be tried on the nook logo screen via various button presses as well but don't have any knowledge about that especially for the color+

Nook HD+ Stuck at CM Boot Animation after several app installs

I installed the latest CM 10.2 (cm-10.2-20130827-NIGHTLY-ovation.zip) as well as the newest GApps. Everything seems to work fine until I install a few apps. Unfortunately I can't say if any of the apps could be causing the behavior which is as follows:
I've had this issue a couple of times already and, after becoming frustrated mostly due to the Nook only deciding to boot from the SD every once in about 30 retries, usually resulting in a revert to stock by default, I gave up and reverted to stock. Of course the taste of CM that I got was too sweet to give up completely. So, today I tried again and had the same problem. Seemingly it will work fine until you reboot after installing quite a few apps. I made sure to restart the tablet several times after installing it and everything went as planned. Whenever the play store had finished installing my swathe of apps, I decided to restart and this is when I was met, yet again, with the rotating CM boot animation.
It's quite annoying really, considering how fast it seems when I'm using it. I haven't got CM installed on the tablet's own recovery partition (if it has one -- I've not read up on these things) but have been running it from the SD. I don't know if that makes a difference. I've formatted all the pertinent partitions before starting the ROM for the first time. I delete the data/cache twice all-in-all, once before and once after. Dalvik too.
Basically I'm flummoxed.

Does it boot up after you clear cache?
I no longer saw this issue after unchecking wallpaper quick render under homescreen settings.

I can't clear cache because I keep the recovery on the SD and it decides it doesn't want to boot from it nine times out of ten, even after following the newer instructions for formatting the SD. After a few failed reboots it just reverts to stock. If I flash CMW recovery to the Nook's recovery partition, will I still be able to revert to stock that way? As annoying as it is, it's nice to have that ability.
I'll try a new install today and avoid checking the wallpaper hack because that appears to cause a problem. I had flashed it yesterday and used it for quite a while, installed all my apps and restarted it many times without issue. After checking that I think I restarted and met the endless logo. Will report back later today.

I can confirm that when I leave the quick wallpaper render option unchecked, it does not lead to a catastrophic failure. Strange that I need to reformat the SD each time or it doesn't reliably boot from it. Either way, I've been using this install for a few days now without any unexpected issues.
Thanks for the advice.
