Have you tried booting with a bootable SD like you did when you put CM10.1 on it? It will not even turn on unless it has valid boot files on emmc or a bootable SD inserted.

Yes i have tried to turn it on with a SD card with CWM. just blank screen. its turns "on" everytime. just no image. only the backlight
Thanks

Well you tried everthing I've seen or could think of... though leaving it on till the battery runs out would be a curious test? If it will even do so.
Edit: You didn't state how long you tried charging it for. If it drained all the way it can take a good amount of time and WILL get stuck at only the backlight just like you have.. The charging symbol shows up later and will finally boot at around 15%'

Since i cant see anything on the screen i can only go by the light next the charging cable. I charged for for a whole day and the light was green on the tablet stating it is charged 100%. i did not try to drain it. will probably take a week or more since i unable to use it.
Unless someone has another suggestion i think it time to throw in the hat? the tablet is only 2 months old so it shouldn't be a problem returning it to the store and getting a replacement
Thanks

I just researched info on the emmc brickbug in the event you were testing or running the rom with trim enabled. Or lagfix too. The brickbug can brick the device where it doesn't turn on. Just something else. Or that is from what I understand anyway.
But it sounds like you might as well take it in for replacement.

thanks for the followup :highfive:. took it in and they tried everything under the sun to get it to turn on. in the end w/o results they handed me over a new nook :victory:

OK, maybe Jtag reflash. Is there such an animal for the BNTV600 on the horizon?

[Q][Help] Nook Color gone completely dark?

Last night I turned off my NookColor via Nookie Froyo, and since then I've been unable to get the device to turn back on.
When I plug it into the charger it appears to be charging, but doesn't boot like normal. (It was fully charged when I powered off, so I don't think it's out of battery)
When I hold the power button, nothing happens (Even for extended periods of time).
I've tried various key combinations, but it's seeming more likely that the thing has been completely bricked.
Any tips or advice?

Most likely it discharged on you, they have a habit of waking up and draining at the nominal rate of 8-10%/hr. I've found mine dead or nearly dead about 3 times because of this.
It'll take about 15 minutes for it to come on after being on the charger if the battery is flat dead. So... is it working for you now?
It's not bricked.

I really hope you didn't replace your internal memory with that Ad 2.2 rom.
2 ways you may can find your nook back ( at least 1 of the 2 ways will work ):
1, hold the power button at least 40 seconds or longer, until you can see it restart. If this didn't work;
2, Burn a boot-able SD card with CWR, and recover your internal memory to stock rom.
Those are normal things what I did when the bad thing happened.

My first instinct was to let it sit for a few hours, then try and recharge it, but after having it on the charger for about 30 minutes now it's not seeming to respond.
Normally when it's died, I plug it back in and get the "Battery too low, wait 15 minutes" screen, but like I said, the device is just staying off.

I've done #1 a few times now (Thinking that I could hard reset it, if that were the problem)
As for #2, I can't boot from an SD because the device won't power on! I'm running Nookie Froyo in a dual-boot state with the stock 1.1.0 rom in eMMC. I'm not quite sure what the "Ad 2.2 rom" is, though.
And thanks for both of your responses
Ad 2.2 = Android 2.2
If you do this : burn the SD like I mentioned, put that into your nook, plug in the power cable, and just hold the power button . It SHOULD turn on in 10-15 seconds.
I use this way many times to save my brick nook, so believe me it is worth to try.
Were you running froyo off emmc? If so:
http://forum.xda-developers.com/showthread.php?t=931720
I recommend flashing this ROM instead though (pre-rooted 1.1):
http://forum.xda-developers.com/showthread.php?t=932145
And yes if you insert the CWR sdcard into the nook and hold the power button, it will power on. The reason it isnt powering on currently is because your froyo boot partition is corrupted, not because of the nook itself. The CWR sdcard has a different boot partition that your nook will see and boot to when you hold the power button down with the CWR sdcard in.

Not to hijack this thread but this has happened to me and I have tried to install the previous two ROMs with no luck... Any help would be appreciated...
I forgot I had a nandroid backup prior to going to Froyo... Lets see if that works... Restoring now...
UPDATE: Well that didn't work either... Still not able to boot up unless it is by using the SD card... Any suggestions?

Your boot partition probably got fu*ked somehow. Go to this thread:
http://forum.xda-developers.com/showthread.php?t=914690
At the very bottom (like the very last line) it says "-Download flashable repartition-boot-with-stock.zip here." Download that file and trying flashing that.
That was it, I must have done something when I tried to recover from the 1.1 push. Thanks to both of you for the help...

[Q] Nook HD+ won't turn on

OK, I've seen this twice (so it isn't complete death) but wanted to see if anyone else had any ideas. I've done a complete shut down (power button for 8 sec) and then couldn't get it to turn back on. When this is happening, I can plug it in and see the green charging light. Holding the power button then for 8 sec will make the green light go out. Pushing it again, light comes on. So the button is working... If i leave it for awhile, the nook will then reboot and appear to work normally...

If your device battery level is below 10 percent it will not turn on until it charges up to at leat 15 percent level. Then it will turn on.

I think that is the mechanism stopping it, but it is malfunctioning, I'm at about 90% this last time...
Is there ther equivalent of 'battery stats' somewhere that can be affecting this? or is this hardware? It should be turning on fine at 80-90% but no. However, plug in for 10 mins and it works fine. So that seems to be the problem.

OK, this is getting worse, I'm now at 100% charge and it happened. Weirder still, if I leave it plugged in for awhile, it will reboot on its own.
I have not had this happen on my HD but something similar has happened on my HD+. It seems to be related to whether an SD is plugged in. I have to take the SD out, press power off for a while, then release and momentarily press power again.
I know on the Nook Colors, they would not turn on unless it could find the boot files to boot from. So if a user formatted his internal boot partition by mistake, it would not turn on unless a bootable SD with active boot files was in the slot. Something akin to this may be happening, only in reverse.

OK, this seems to have worked. I tried to change the partition of my CWM SD card using EaseUS, but that seemed to make it no bootable, and removing it does seem to have worked. Now I can boot a new reimaged CWM card.
Thanks!
Good to hear that your nook is working again.
It seems i am having a similar issue, only a little more severe.

Something similar happened to my HD+ running the 12/31 build of verygreen's CM. In my case, I think it was precipitated by the battery draining too far first, though. Very weird and a little spooky, but glad there's a workaround.
Wow, this is dumb. I can't believe a badly-formatted SD would cause it to look like it's broken. Put a message up or something. Thanks for the help, thought something was really wrong!
Nook HD Plus won't charge
I've seen dozens of reports of this. The symptoms are all about the same.
The unit drains the battery, even if you plug it in, it still drains, so although the charger and cable are fine, something inside the Nook doesn't get the memo.
It drains down to the point where it turns off. Then every time you plug it in, the light goes green, then amber, then off. The battery never charges.
I tried taking the unit apart and disconnecting the battery overnight, but that didn't seem to help. I suspect something in the software gets in a "vapor lock" where a dead battery condition is mistaken for a fully-charged battery condition. I only paid $109 for it refurbished, so it isn't worth another $60 for a new battery, and I don't think there is anything wrong with this battery.
If I knew the pinouts of the battery connector, I might try charging it without going through the Nook. Perhaps if it was actually fully charged, the "vapor" would realign.
Does anyone have another idea, apart from the nitwit stuff Barnes & Noble allows on its forums, like "push the cable in harder" or try another adapter. I notice they aren't interested in entertaining any idea that their firmware is at fault.
It will not charge when plugged in if OTG USB is activated (e.g., to connect a USB keyboard). That's happened to me a few times using unofficial VG CM versions where the USB state can be changed inadvertently from a pull down drawer. If the USB isn't toggled back to normal in time to recharge the battery before its completely discharged, it might not be revivable.

I've the same problem, except even if I leave it a while, it doesn't boot or even appear to start. Is there something wrong with the battery or display? It was working perfectly fine until suddenly the screen froze and I had to do a complete shut down.
I cant get my nook to turn on. I try charging it and a little green light comes on at the bottom and stays on for about 3 seconds and then a orange light comes on for about 3 seconds and then it shuts off. I dont know if the light is supposed to stay on while it is charging. Sometimes it comes up with a dead battery sign but it just goes right back off.

[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] help! Nook hd+ cm 10.1 suddenly no power on!?

So... I had my Nook HD+ plugged in to my laptop for adding new video files. I went to unplug it, and it said something about "Powering Off" on the screen. I waited until it was off for about 2 minutes, then tried turning it back on. First by a quick press of the power, because I didn't realize it had completely turned off, as it had never done that before when I unplug it. Then I have been trying full 10-second press of power, and several tries, NO POWER! I have no idea what the heck happened, I have been using this tablet with the new CM10 version mod, and have not had any issues. I usually have it in sleep mode and on the charger cord. I was getting ready for a day trip in the morning, and now it's like a paperweight.
PLEASE HELP!
When you plug in the charging cable, does the LED light register anything at all?
Rather obvious but you have tried plugging it in to the mains for at least 10 minutes?

I assume you mean the charger? I had it charged to 75%-80% before I'd put the new videos on it, so I didn't think that had anything to do with it, it shouldn't have been dead already, but I did plug it in to the charger so it went to full power, and for a long time it just showed a battery with a bolt on the black screen, but now it appears to be working. Thanks
Try removing your SDCard and turn it back on, welcome to the weird world of Nook. Put the card back in once it has booted up. Can you let me know if this at least lets you boot.

Well, since I already got it working again, I will just hold on to your suggestion for when it crashes on me again...

[Q] Nook HD won't boot

Hi,
I've owned a B&N Nook HD (7 inch) for just over a year, when I first got it I flashed CWM and CM10 onto it and ever since have had absolutely no issues with it, however a couple of weeks back I was having trouble getting it to charge, it would take a few tries of plugging the cable in before it would finally begin (I'm not sure whether this is related at all to the issue) However a couple of days ago I was happily browsing the internet, then it made a strange "Pop" sound and the screen went completely black. Ever since then it won't boot up, it will briefly display the Nook logo but will then make the same pop sound and go to what looks like a black screen, however under low light you can see that the backlight is still faintly on, and to turn it off you have to hold the power button for 7ish seconds. Also on one attempt to boot it made it past the nook logo, and onto the cm loading screen but then had the same issue. I've also tried booting it to recovery but with no success :crying: .
Any help would be greatly appreciated, even if it's just to say that it's a complete right off.
Thanks
Probably you might have damage battery

Please watch this tutorial how to remove battery. https://www.youtube.com/watch?v=YfYvhtw30mU.
Then charge your battery via external power source i.e.Master charger. If you still can't turn on your device. Then buy new battery. Link of ebay is http://www.ebay.com/bhp/nook-battery
If it is software issue @leapinlar will surely figure it out.
Thank you very much for your quick response, I'll give the link a try!
Battery Charged

I had a go at removing the battery, but as I don't have a Master charger or anything like that around, just stuck a multimeter onto the connector, and it read about 3.5v so to me that seems pretty charged.
Does this mean it is a damaged battery, as I'm on a bit of a shoestring budget, so want to make sure I'm getting the right thing

I've install stable cyanodgen 10.2.1 a year ago and have this issue ever since. Not sure if it's common but whenever the nook is drain completely to dead...when you try charging it..the light would be green..then amber. So I don't know whether its charge or not but I guess it is. I would not be able to power it back on...the normal way. It would seems dead. The way for me to get it to power up is to get into cwm recovery by pressing both the power and home button at the same time, then reboot it. It gets annoying because I would have to do that all the time since my 5 year would drain it out lol
