Having a problem with the lock screen in CM10.1 that is happening more frequently.
It seems it happens after I open the case lid and the Nook HD+ wakes up. I use pattern lock (but it's happened in the swipe lock also), and for a moment, it looks like it's unlocked. The desktop or app that was up when it went to sleep is there, but only for about 1 second. It goes right back to the lock screen. It repeats over and over. At first, I thought only a reboot would fix it and allow me to unlock it, but I found if I hit the power button to put it to sleep and wake it up, it typically unlocks. Sometimes it might need me trying that a couple of times, but it usually works.
Ideas? Anyone else having a problem unlocking after sleep? So far, I'm not sure if it's just lid-induced sleep or if it would happen after I use the power button to sleep it.
Again, it doesn't happen all the time, but i'm finding it happen more frequently.
Thanks!

I have heard about this problem from several people, but usually it is on an HD+ with the cover that wakes up the tablet. However, I just experienced this a few minutes ago and my Nook has never had a case on it, let alone one that wakes it.
It happened when waking it with the n button but after turning off the screen with the power button and back on with the power button, it worked. (not turning off the Nook, just screen off and back on)
So it appears that it is not only the magnetic wake up that causes the issue.

Mine does that too. I thought it was a hardware defect, but I tried another one and it does exactly the same thing.
So far it's only happened with a case-induced wake for me. It happens regardless of whether I sleep it using the case or the power switch.
The lockscreen loop stops if I sleep/wake it using the cover consistently, but it doesn't go away if I sleep/wake it using the power switch, oddly.
same problem with no known solution

I have the same problem and no solution. I wonder if a newer release of CM would help.
Also, in regards to temporary coping, when this problem appears is there a method (besides reset) to deal with the problem. I noticed that sometimes I can eventually get past the lockscreen without restarting, but I'm not sure what causes that. The best solution I have for my wife at this point is I delayed locking-after-sleep to 30 minutes.
Two-user set-up (my wife and me). I am fairly new to the scene--first time I ever loaded CM on any device. I recently bought the HD+ from Best Buy for $150. I tried to follow the verbatim instructions from e.mote titled "[NOOK HD/HD+] Installing CyanogenMod 10.1 for Dummies." I haven't used custom ROMs much since my heady days with my Palm Pre.
I'm in the same boat. Hd+ running CM 10.1.3. I wonder if this still happens on the 10.2 builds...
While on 10.1 this happened to me every time after charging (well, maybe not every time, but that's when it happened...), but if I just turned off screen and then back on I was fine until next charging.
I put on 10.2 earlier today (from Iamafanof site, so not from here). Will be interesting to see if the problem is till there, but I won't know tat for a while yet.

Im seeing this on both 10.1 and 10.2 on my nook HD no cover.
I'm seeing this even without a lock screen. The screen turns on for a second, after that turns off. After many tries it works or after a restart. With lock screen it is the same as above.
Happend on CM 10.1 and CM 10.2 with a cover
So there's no solution to this problem and you just have to reboot it?
You just close and open the cover again

I'll try that again but I don't think it worked.
I have been having the same issue as well with mine. Just curious if really has been a solution to this?
No it is a hardware issue. There are two options close and reopen cover or cut magnets out and turn on manually. I don't think anyone has tried more powerful magnets if you want to test that it would be helpful.

I kinow its an old thread, but I Fixed it by closing and opening the magnetic cover, rather than using the power/off/on screen button and it worked.
Only fix is to do one of three things. Remove the magnet from the cover, remove the cover is self, disable the lock screen. It's because the cover and lock screen confuse each other and it has the cover wake it, then the lock screen sleep it, then it sticks. It's very well known, and nothing to panic over, just really freaking annoying.
Hello,
I am not sure I am in the right spot or forum but I am running cm-10.2-20131111-NIGHTLY-ovation.zip on a Nook HD+ and it is running beautiful but, at times the entire device locks up. This happens on the lock screen and when swiped you just see a flash of the home page then right back to lock screen. Will not allow entry. Happens when the device sits even for only a few minutes. Need to reboot to get back in. Then works fine, let it go to lock screen (will not allow entry). Anyone else having the problem? Right now I have the lock screen turned off and appears to be running fine. Happened with original install and now two of the nightlies.

Usually that is caused by your case with a magnet in it. If you have that, open the case twice before attempting to swipe.

My HD (running 10.1.3 stable) has just started behaving strangely when I wake it up from sleep. The screen will flash then go black. Whether I push the Nook button or the power button, the same thing happens. It may do it 2 or 3 times before it comes on. Started doing this yesterday. Just now, it would not come on at all. I see the screen for a half second, then it goes black. Just wondering if it's already toast or if this is a known problem with a remedy.
Probably software issue.
If your using a magnetic case (problem)
You could try disabling the lockscreen if its enabled.
Daydream could in my theory affect that time frame.
The backlight should last years longer. The gpu should as well. I can't think of any other hardware issue.
If you have an sdcard try cm11 [or the bn rom] and see what happens. OR full backup of current rom in cwm and flash cm11 to internal. Clean and restore 10.1.3 and be back to right where you left off.

Yes I have the same flickering issues when trying to wake it up from sleep. I would have to press either button numerous times to get it to stay on and not black out. I'm on the same 10.1.3 stable. I am using a magnetic case but it happens without it. Before this happen, my slide to unlock screen would act up by not unlocking when I slide to unlock; it would just go back to the initial lock screen. Slide to unlock would not work so I turn off the lockscreen, now experiencing blackout screens when I try to wake it up by pressing either buttons. This problem happens infrequently but it is annoying.

I learned from another post that if it does not awaken when the magnetic case is opened the first time, close and open it again. This works for me 95% of the time. Sometimes there's 2 or 3 second lag but it almost always comes on.

Works like this on my HD+, too. Sometimes requires opening case cover twice, but the screen always comes on.
I have the same problem as others that sometimes after sleeping with the magnetic cover, even with the correct password I could not log in. I have delayed the screen automatic lock to 30 min and usually have to fix it with a restart if it happens.
I have another problem that if I have the nook covered with the magnetic cover for a time period longer than 2 hours. It seems to have been turned off. I have to try holding the power button to turn it back on and it will go through the nook splash screen and then the cyanogenmod start animations. Is this something expected with cyanogenmod? Has anyone else experienced this?
If it's a bug, I am wondering whether updating to CM 10.2.1 will fix it. I have read the first problem cannot be fixed and it might be hardware related. Is the second problem hardware related too? Thanks,

You need to open and close the cover twice. It is a known bug on all CM versions.

Hum, I can't seem to reproduce my second problem for the last two days. The symptom was that when I tried to press the nook button or the power button to wake it up, nothing happens, it stayed at the black screen. I guess basically what I did was holding the power button to shut it off and then turn back on. I guess it might have needed a second time of opening the cover. I will keep watching and see whether this is the case.
I purchased new A71, it's screen gets on by itself after every one or 2 minute. I checked simply whatever possible. Any ideas?
Never had this issue but did you try tweaking AOD settings?

Already,,, no use.
Now safe mode tried and no screen wakeup.
It means some third party app issue.
I'm trying to figure out which app exactly.
I had this with my wife's phone.... Screen literally cam on everytime the phone was moved.... She has a flip case, which i assumed was the culprit, and i could see the screen pop on even if she moved the phone to one side a little...
I found the answer to our solution in the settings somewhere under advanced features/motion and gestures.... Untick all that lift to wake crap!
Screen stays off now until you press power button or double tap screen...

I tried the same already but problem was still there.
Since once I reboot into safe mode, there w no issue. then started apps one by one in normal mode,,,, now not facing issue. I suspect one or two third party apps. Still not finalised which app exactly as these apps got updated meanwhile.
Any way thanks,,,,
my issue already resolved.
