[Q] can't charge or turn on my nook hd+ at all

My nook was idle for a day or two, as I remember I hv shut it off.
But then yesterday I try to charged it, the light was green then turn to red, n then it went off, usually the nook would turn on right after I plug the charger. So I didn't notice it until today, and I tried to turn it on by pressing the power button, and the N button together as well, both didn't work.
It seems that I can't charge it or turn it on. Everytime I tried to re-plug it to power or press power button while its connected, the light went on in green to red then off again.

Connect your charger. Let it stay on charger 20 min. Then try push n button. If this not bring screen on then try push power button for 5 sec. Again if not then try power and n button combination.
Hope this helps.

Thx! Turns out tht external charger didn't work.

I think that last opinion is make CWM sd card (without CM10) and insert it do device, then try to switch the device on (with charger trick or power button). If you then get it live all is ok. If not then last change is wait when battery goes empty and charger wakes it up.
Actually i predict that item is itself faulty and you must return it for change (maybe not faulty at hardware side, only OMAP inside code got corrupt).

I don't know, that might because I rooted my device, and I did sth wrong. Sometimes it would reboot itself, since my cmw card was inserted, it would load tht root page so I found out. But I live in Asia so returning the device might be too costly, probably won't do it.

It could be several things. The most likely is it was trying to update itself and could not because the CWM card was there. I don't think your device is defective.

Now i can say same. With first information things was other.

...It's more or less a known bug to those of us who use CM10 (even to some who use stock), the battery simply often can't tell how much she has left. So she may fluctuate from 1% to 26% to 0% a moment later . In one such moment my Nook HD+ shut down (went from 26% to 0%). So I put it up for charging thinking (naively) that it would boot up ... it didn't, now all I get is a charging icon that never goes away (orange led remains lit). What's more I *know* it has some charge (the "26%" was the right value) and I know the battery works, so what prevents it from starting is the "battery charge sensor".
It's a pretty silly way to lose your (my) tablet over. Even more so given how much I grew attached to it for my workflow. So what's next? Is there a secret way to convince it to boot. As I said both the hardware and its software is in top condition. I guess an alternative would be to ship it back for replacement but I'm afraid that I've lost my receipt and -as I said- it's a silly way to lose your tablet over, there *has* to be a (fast) way out...
BTW when connected to my PC my device manager briefly shows an "Omap 4470" unknown device (with an exlamation mark) which goes away few secs later, so I cannot attain ADB control over my devices either (sadly)....

If you are running CM10 or 10.1, there is an easy way to connect with ADB. Do it wirelesly over wifi. That is built into CM. Just enable it in the developer options. No need to mess with the USB cable and windows drivers. You can do the same thing with rooted stock by installing an app called ADBWireless.

At the time that could not happen , since (as I had implied) my nook was not booting to begin with...
Anyhow, what I did was to leave it for three solid hours on the charger, and after that period of time it booted on its own wiithout warning. It's the first that such behavior was/is ever present to my nook and it's deeply worrying. A battery fix for the CM kernel couldn't come any sooner; now, if only verygreen was around

There's a few ideas on a couple of other threads including putting it in the fridge, etc. Question, if you plug it in, does the charging light come on? Does it come on after pushing the power button or the N button? If so, take your SD out, leave it charging overnight and try again. It often reboots when in this state and if there's an update problem, that could be the issue. Also, it is sometimes erratic on when and how it charges, be careful with the connections.

As I said it came up on its own, without warning after leaving it for 3 hours on the charger...
As for your question, the led (charging light) was on all the time but it would only show me that it had no battery (couldn't charge even though it was ... charging?)
Maybe the fridge makes sense in those situations, as it was indeed into a (relatively) hot environment and maybe it couldn't charge as a safety against overheating and since (at the same time) it also thought it had 0 battery. But what I can't understand is why needed 3 hours before starting to charge up, it was already cool enough long before ... strange things are/were happening with my battery all along and I worry...

Yep, I've noticed the same thing a few times. It no longer panicks me. When it doesn't turn on, I take out the SD, plug it in, wiggle the connector a few times, and let it alone. So far, it has always eventually rebooted, often as you say on its own. Quirky, but not fatal at least. One poor guy on here never did get his to turn on, but the key was the charging light,his didn't come on.

Need help cannot turn on Nook HD+ at all
Hi!
I cannot turn it on at all and it won't reboot.
It went out some point I didn't watch it. When I connected it to the charger the LED next to the connector starts blinking amber and green for a few seconds and then stays blinking red and makes a high pitched noise.
The only reaction I get is when I press power on an volume down after some time - it display turns on an shows a charging sign - but it never really seems to fully charge. I left it on the charger over night - still the same. Once the display blinked and showed “nook” but went out immediately after a few milliseconds.
Might it be some kind of bootloop!?!?
What combination to press to make a reset?
Thanks in advance for any help

[Q] what exactly is going on? phone not turning on

Hello everyone,
So I am new to XDA forums and I have a few questions about the HTC Vivid. I just recently purchased a phone for cheap just to practice doing how to root and do certain task on phones. When I purchased the phone I knew that the phone was not working properly. When I tried to turn on the phone nothing happen but I saw that the screen did light up in a black screen. I took the battery out and checked the battery and the connection to the battery on the phone everything seems fined. When I put the battery back in and tried to turn it on nothing happened. Think it might just be a dead battery I charged it all night. While changing I noticed the phone led light was not constant it kept blinking and a screen showed up real quick and it looked like it booted into recovery real quick and shut off. It kept doing this by itself for a while. (Cycling) Then it finally booted into the white boot screen with the HTC Logo. I thought the phone was finally going to work but nothing happened it continued the cycling process again for a while. Thinking there was a possibility of fixing the phone I connected it with my PC and using both Windows and Linux. When I connected it with Linux (Ubuntu) nothing seems to happen. When I connected it with Windows it does the same thing as if i charged it. The orange led light blinks a couple times and then becomes solid for a bit and blinks again life it was Morse code. This time I see a black screen lighting up more and boots fewer times booting into recovery. I think it booting into recovery because I remember the CWM. Through all this process while connected with my computer I see that it is attempting to connect with my computer but then shut off. After approximately 8-10 minutes of cycling i get the white screen with the HTC logo again and then the cycle happens again.
My question is what is the problem with the phone? A few things that pop into my mind is probably just the battery is fried, the microusb is bad, or something went wrong during the process of flashing something onto the phone. I was very detailed about the problem and what I noticed because like I said I purchased this phone only to learn how to root and do other various things on a phone. Is the phone salvageable? I will post a video later if my detailed description didn't make sense or you just have to see it happening.

OK, first thing to do is to charge the battery in an external charger. That is the *only* way to eliminate the battery as a problem. If the phone wont boot with a fully charged battery, see if it will boot into recovery mode. If you can't do that, it is quite possibly dead.

[Q] [Help Thread] Nook HD not booting at all

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral

Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!

It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue

I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.

YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience

Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.

From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.

constant reboots in, cwm,cm boot logo and cm11 it's self

I'm getting constant times when my nook HD+ just shuts down, it first happened in cm11 the 9/11 nightly, it would shut off when I went on certain web pages and on YouTube, then it would shut off when I tried to change the wallpaper. It would then shut off at the cm boot logo after about 2 seconds,only being able to boot fully after repeating about 4 times. So I did a factory reset and reinstalled the rom, but then when I tried to install gapps the device would shut off, so I went in did factory reset again and formatted system, installed the ROM and gapps fine this time but the first time it still shut off at the cm boot logo, its now booted back into cm 11 the second time but still getting shut off's when I try to apply wallpaper etc.
I've re installed the stock ROM and I'm still getting random shut downs and its saying my battery is 1% when its fully charged
can anybody help please ?

i have been having this issue for like two months now. it all started when my daughter ran the tablet out totaly. took a good three days of tinkering before it would actualy take a charge. now i get constant shut downs, flickering screen. will say im 100 percent charge and when take the cable out it will go down to 1% i dont think the battery is bad because sometimes it will actualy hold the charge.

Could be the power connector or at least somewhere along the power path. My old kindle had what looked like battery issues which was actually the cable itself at the port that was a bit loose and a different cable had fixed it - it even said it was fully charged but drained 4x faster (give or take). After the fix the battery life was normal again.
Its would be incredibly confusing [to me] if draining all life from the battery is the cause of your problems as I do it often with all phones/tablets (and others do it) and its never caused me a problem not even once. I do it on purpose not accidental.
More likely a coincidence and not the actual cause and the issue is that something was damaged or going bad. It doesn't sound like a software problem. And since it appears to be battery related that would likely be the battery or related path such as the power cable, port, wall plug.
Since its made by humans, I'm going to say if it turns green fully charged then its not necessarily anywhere near fully charged especially if the incoming power wasn't the proper amount, it could potentially be thrown off and confused instead of what one would expect happening that of either/or.
Wrong or right there's my best guess. Do with it what you will.
Adding if its still under warranty (I would assume), according to leapinlar, BN will give you a new power cable if that's the problem, or same with the device (as I took advantage of for hardware defect).

They will only give you a new cable if it is still in the warranty period AND it still is running stock. You may get by with just taking the cable in, and if they can demonstrate it is defective, get a new one. But if you bring the device in with CM on it the warranty goes bye-bye. So if you take it in, be sure stock is on it.

*gasp* the rest of it. Thanks for the correction there.

GOT IT
So i took it apart thinking i would replace the battery. Didn't end up having to. i disconnected the battery from the main board, then plugged it back in. tablet fired up and showed 100% battery. haven't had a single issue since. :good::good::good:

Nook HD+ will not power on. Read threads and found no fix. Help?

I charged the Nook HD+ for about 2 days. It seems to be fully charged. Light stays green no matter where I plug it in(Laptop, wall) and I have tried two different cables.
This is actually my sisters device. Mine is the same one, and both cables work on it with no issues.
This device has never been rooted or messed with in anyway. Its fully stock with current updates.
If I attempt to power it on while it's plugged in the light goes black and never comes back on. Same thing happens if I try the power+n thing. I attempted this while plugged into the wall aswel as my PC.
Any ideas? Battery, screen, or just fully trashed?
---------------------------
New Information:
I thought this was my sisters Nook, but after asking her if she had ever opened it up she informed me oh, its her friends and hoped I could fix it.
It may have been opened, I have no idea what its been through.

If the light is green while plugged in, it is not charging, no matter how long it's left there. It only charges while the light is amber/orange. How long has it been between charging before you got it? Have you tried plugging it in, and holding n+power to force it to completely shut down (sometimes it makes a difference, because it tries to boot with little power, and hangs in limbo). Also, if ithas an SD card in it, try taking it out. If it's an older card, and worn out, it can cause that same issue for you. I've tested that with a bad card in a NEW Nook HD+ and managed to make it act like it was broken until the card was removed, then all was fine with it. It's too soon to tell if the battery is completely gone, but I doubt the screen is the issue.

Also, if ithas an SD card in it, try taking it out. If it's an older card, and worn out, it can cause that same issue for you. I've tested that with a bad card in a NEW Nook HD+ and managed to make it act like it was broken until the card was removed, then all was fine with it. It's too soon to tell if the battery is completely gone, but I doubt the screen is the issue.

I amended my post, but will repeat here:
I thought this was my sisters Nook, but after asking her if she had ever opened it up she informed me oh, its her friends and hoped I could fix it.
It may have been opened, I have no idea what its been through.
As for an sdcard, no none in it when I got it from her. The screen never even lights up so if the screen is dead, I don't know if it's on in anyway.
I have plugged it in, (light is green) and pressed power+n, when I do the green light goes black and never comes back on. Should I just leave it for a day and see if it charges in the least despite the lights being black?

I have the exact same problem, with *my* sister's Nook HD+.
After a lot of research and playing around, and even getting a new battery and installing it, it still stays green and never boots.
The reason I understand is that the bootloader (x-loader) has got corrupted. If Barnes and Noble could release their tool used for flashing the bootloader, the device would be up again. Plenty other vendors like Samsung, LG etc. have such custom utilities for their own devices. However, BN haven't released theirs.
The 2-nd stage bootloader needs to get downloaded into the device. Only then any other recovery image can be installed.
Just for their unwillingness to release the flashing tool, devices are getting destroyed.

Annoyingly I seem to have forgotten to charge my Nook HD+ and the batter has drained, and now shows no signs of wanting to charge and reboot. The led stay on Green and no amount of pressing the power button shows signs of life. Guess off to shop at weekend for new tablet...
