A while back my HD7 (TATE) running Beanstalk OS (Marshmallow) started acting peculiar.
If unplugged from the charger, it will boot up just fine into the OS. However, after the screen times out, it will instantly shut off and begin to reboot. It will keep doing this unless I keep the screen on (using it) or force it off completely (shut down, or press and hold power for 5 sec). It seems that my Kindle Fire HD 7 doesn't like going into Sleep mode. I looked up and tried changing some of the default sleep state values via kernel editor, but nothing seems to help or make a difference.
I thought maybe it was the battery dying at first, so I tried to plug it in. I noticed that if I plug in the charger during the boot process, it just instantly dies and refuses to wake up unless I unplug it. However, once it is completely on and booted up, I can plug in the charger and it stays on and charges. That is, unless I let the screen time out... then it attempts to reboot but instant death because the charger is in during boot.
Oddly enough, I'm able to charge the Kindle when it is completely powered off by plugging in. Or I can leave the screen on by changing the power settings, and let it charge that way. Its become very difficult to use like this, however. Everytime I put it down, I have to either power it completely off or come back to a dead battery from all the bootloops.
In a nutshell, it seems that my KFHD7 Tate won't charge unless completely powered off or on- during boot it causes it to lock up until the cable is removed. It also won't sleep, as once the system times out the display and tries, it reboots.

My phone (which is currently running Incubus26Jc's Android 2.2 FroYo RLS10 NAND) rebooted at around 12:30 AM. I noticed that it reboots, randomly, about twice a day. Not sure of the cause, haven't looked in to it, but normally it comes back to the desktop, like a fresh boot of the phone. So I thought nothing of it.
Last night, however, during the reboot, SOMETHING happened, and it seemed to have gotten stuck in an infinite loop. It would show the boot animation for a while, then lose power... then it would notice the power cable was plugged in, and try to automatically boot up.
If you notice, plugging the power cable in forces the phone to boot all the way into the Android OS. There seems to be no "charge while off" feature, at least for me.
Anyway, this endless loop caused the phone to reboot over and over and over, until the point where the battery was so far drained, that this "hand off" between the boot screen and the actual OS (somewhere during the boot animation) where the phone had to run on battery for a split second, was long enough to cause the phone to power off completely.
I couldn't flash back to Windows (I thought) because the phone didn't have enough of a charge to stay in bootloader mode while flashing the phone. Which was mostly true.
FYI (how I fixed my problem): should something similar happen to you, put the phone in true BOOTLOADER mode (hold the camera button when you press the power button, see the colored bars across the screen), even though the indicator doesn't light up, the phone DOES charge when in this mode and plugged in to a wall charger (and probably while plugged in to USB).
As far as I know, you are required to maintain a certain level of charge to run the RUU because the USB cable cannot charge the phone WHILE FLASHING, but while waiting in bootloader mode, the battery will charge. I was able to let the phone sit at the bootloader for about an hour then started up my phone and had over 70% charge according to Android. Working again!
thank for the 411. i had a similar issue with rls10. went to 10.5 and rls11 and flashed a new kernel, no further issue since
I recently installed CM7 nightly 12 and it's stuck at this screen. I'm using the stock charger. I've tried plugging it into my computer too.. no luck. Is there anything else to try? Am I screwed?
this sounds like something that was happening to me yesterday. i finally got it to charge by making sure it was completely off. i finally realized that even though the screen was dark it wasn't off, so it never charged (i think it was just recycling the charge enough to keep it on). if you look at it in a dark enough light you can see the screen is still on (backlit).
so plug it in, i would suggest using the wall charger. this usually makes it turn on (at least mine did), once it does, hold the power button until its off, no backlight is on. hope this makes sense and helps out a little
There's many others having this problem (me, on my friends nook, one of them). Hold down the Power button for a long period of time (I heard it's 10 seconds, but someone said they had to hold it for 30) and it will do a hard reset. At that point, try to turn it on again normally. If it doesn't turn on normally, plug it in (using the uSB cable that came with it (that is very important) and into the wall with the provided adapter), wait 30 minutes, and try again. It seems that very few (I don't know if i've actually read of any) who had this problem actually had to return the nook. When it happened to me with my bro-in-laws, he just hed the power button cause he was mad and it turned on, it hasn't happened to him since
Finally started working. I tried holding the power down for awhile with no luck.. Left it charging overnight and tried holding power again and it worked!
It was charging for most of the day, so the battery isn't dead. I turned it on and then the screen went black. Now it won't do anything unless I plug it into the computer or wall. I didn't root it or change anything.
I pushed the power button again for about 30 seconds and now it works. I don't know how to delete the thread.
I looked in the previous threads about non-booting but no one I could find had my issue. Bought the Nook HD+ about 4 months ago and rooted it and installed Android (not sure which version but cm11). Out of the blue, last week I pulled it out of my bag and the battery % was flipping between 1% and 31%, so I put some stuff on it via USB and then shut it down to charge. I plugged it in overnight and tried turning it on in the morning. All I was getting was the low battery picture, so I kept trying to charge it, but it wasn't charging, the power light would go to orange when I plugged it in, thena fter 3-5 seconds it would flip green and then turn off and retry. My assumption is the battery is dead, but it could be a corrupted OS now as I got it to charge long enough to get to the CM11 boot menu. But I even went out and bought a new charger and converter to rule that out and it still is stuck in the same boot sequence. I obviously can NOT charge this thing while it is off because of it's reboot loop, it can't charge. I'm not quite sure what is going on or whether it is a battery or boot issue but after I leave it for a big it freezes on the cyan picture (which is frozen on some scrambled version of it) until I turn it off.
I can't power it on enough to charge it to rule out the battery, I tried holding the power and n button for 3 seconds, letting go of the power, and then pressing it again to get into the recovery menu, but that isn't working either. And I prepared another SD card for a second flash for a corrupted OS and that didn't seem to work either.
I'm stuck here and I'm not sure what to do now to get it running again. I don't care about the data on my tablet at the moment.
Try plugging it into a PC USB port over night.

That's what I did that got it charged enough to get to try to boot, where it now shuts down. But now as it tries to boot it reboots, maybe from too much power consumption? I only had it plugged in for half hour or hour before that got it charged to the point where it boots to the logo screen. I have a feeling it is not charging because every reboot the light turns off (orange light stays on for like 5 seconds)
I will plug it in to my PC and charge it overnight and let you know what happens. It's interesting, I plug it in now and the orange charge light comes on, shows the Nook screen, then shows the low battery screen and shuts off, then the orange light turns off, but it remains plugged in... not sure if it is still charging but as I said, I will leave it overnight and see what that gets me.
No success. I can turn it on and the charging lights turns on for 5 seconds and shows the nook screen, then goes black and shows the low battery screen, then immediately shuts off and the charging light turns off and it no longer charges.
Any other suggestions? I can't seem to do anything with the Nook now.
After initiating my first trim attempt, I left my device alone for a bit assuming that it might take awhile to complete the process. Upon returning to the device, however, it would not power on. It took roughly half an hour of fiddling with the device until it eventually turned on again without issue (not sure what ultimately got it to work). I trimmed again after booting up and the operation succeeded almost immediately, fixing the lag issues I was having.
It's now about a month later and I attempted another trim which froze my device (no screen activity, system clock unchanging). After about 15 minutes of waiting for a change, I powered the device down, plugged it in, and went to sleep. Attempting to power the device on today has been impossible, and plugging in the charger simply shows a green light (even after unplugging the device for about half an hour). If I hold the power button for about eight seconds, the green light turns off until I press the power button again.
Any ideas on how I can proceed?
Today I looked over at my tablet and found that it was on, but stuck at the "Nook" loading screen. I held the power button until it turned off, then tried to turn it back on with no luck. This is bizarre.
When plugged into my PC via USB cable, Windows continually sounds the device connect/disconnect jingles and says "the last USB device you connected to this computer malfunctioned, and Windows does not recognize it."
