Hi, guys.
Inert/dead/hung Nooks can sometimes be resurrected by this insanely easy trick.
First, so you’ll understand what’s going on:
All the Nook Tablet’s buttons are really soft buttons. Even the Power button is really a soft button: All it does is communicate with the OS.
That’s worth stressing: the Nook power button is not a simple mechanical on/off switch, but a switch that sends a signal to tell the operating system to power off.
It’s sort of like the power button on the front of most PCs. The real on/off button is usually on the back of the PC (and is absent on a Nook). A PC’s front panel button, like the Nook’s power button, communicates with the OS, sending a shutdown signal.
Why is this important? Many times (in my experience) when a nook appears dead or even bricked --- dark screen, totally unresponsive to all external input --- it’s not actually dead, but hung in a software loop.
If the Nook had a true power-off switch, you could depower the hardware, and do a cold boot. That would kill the software loop, and the system would start from scratch, rebooting normally.
But without a true power-off switch, there’s no way to stop the loop, which will run --- conceivably many weeks --- before the Nook battery runs flat. Even then, a slow decline of battery power may allow the Nook to suspend itself --- in the loop --- meaning that when you recharge, the loop resumes looping, and you still have a dead nook.
But you can force a fast battery shutdown.
Wrap your nook in airtight plastic --- a 1gal freezer bag is about perfect. Squeeze out as much air as possible. Put the Nook into your refrigerator for 3-4 hours. The cold will cause the battery to lose charge very quickly.
After 3-4 hours, remove the Nook from the fridge, but leave it in the sealed plastic. Place it someplace at normal room temperature, where air can circulate freely around the Nook. (A cookie sheet or something similar is great.)
The plastic will ensure that any condensation that happens will happen harmlessly on the OUTSIDE of the bag, where it can’t hurt the Nook.
Wait until the plastic is dry and the Nook feels room temperature.
Remove the Nook. Recharge for 15 minutes. This will put back just enough charge to get your Nook bootable, without resurrecting any suspended processes, if any.
Turn on (leaving the nook plugged in). With luck, your Nook will now do a normal power-on full boot. Finish recharging normally.
I’ve done this four times on my Nook tablet. Works like a charm each time.
(I know this tip sounds sketchy, but it’s real. Google me, Fred Langa, if you wish: I’ve been a professional technology writer for 30 years. Of course, your mileage may vary; I can make no guarantees that this will always work. But the logic is sound, and it's worked for me.)
For me, pressing power and volume+ together for a few seconds (forcing the device to power down, I think) usually does the trick. Not sure how the battery would like the fridge method...
wow, i've been reading your stuff for many years ! its 'great' to have you as part of the nook community. really !
.
( secret ) i would like to crack this nook open and solder on a real 'power switch' and 'power led' . . .

If the OS is truely hung, the power+volume won't work, alas.

Chilling (not freezing) the battery has no long-lasting effect. Many MFGs actually recommend storing uninstalled batteries in a fridge.
Wouldn't it be a lot faster to just open the case and unplug the battery?

The issue most people have isn't a software boot loop problem. Dead devices are usually caused from not understanding how to flash ROMs. Deleted internal partitions and such. It's always essential to learn exactly what you need to do before you do it.

Yes, I agree, most bricks are the result of a bad flash. However, that is not always the case.
I have a Nook Tab that I rooted way back in 2011 with the NookZergy method. It is my daughter and wife's tablet, so I did not do anything else. I only rooted so I could put Amazon App Store and the Play Store on it instead of buying over-priced apps through the B&N Store.
After a number of months the power button stopped working completely. I thought it was a hardware failure, so I added an on-screen re-boot button widget.
A few days ago, the unit appeared to be off, yet I could not get it to turn on via that "normal" ways (plugging it in and letting is charge for a bit had always resurrected it in the past). After reading this thread, I opened up the unit, unplugged the battery cable, waited 5 minutes or so, and plugged it back in. The Nook booted right up on its own...
The point of the OP was to completely drain the battery to give an opportunity for a hard re-boot. I was just making a point that, instead of taking hours to do this, it can be done in a matter of minutes if you have a t-10 driver bit...
There is an easier method .
JUST HOLD THE POWER BUTTON FOR 30 - 60 SECONDS .
holding for few seconds will tell OS . Holding for >30s will shutdown by force . No need of volume button,etc.
End of story .
Do not follow OP instructions . Crazy method . Dangerous . If put in a freezer there will be condensation for sure (even a little air trapped inside cover will condense), not to mention potenial cracks or solder troubles inside due to thermal contraction. As a last resort if all else fails maybe.
When my screen went blank , I connected via USB and used ADB to reboot it . But then I learnt to just hold Power button for a long time.

You should go back and re-read my post. My power button doesn't do anything... I have used ADB reboot when the unit was locked up with the screen on... I never thought to try it with the screen off. It is probably faster for me to open the back and pull the battery cable than it is for me to refresh my memory on ADB anyway!
So I put my prime on my bed (it was on and working but closed in its dock) and proceeded to move my sheets to get in bed. The amount of static electricity it created was amazing (its been very cold and dry here) I didn't really think anything of it. I've shocked my prime touching it many times, however its completely dead. I have tried everything I could find in any post but it basically come down to this.
I let the unit charge fully and the green light comes on, but no matter what buttons I press and hold it never once vibrates (held power over 2 mins), nor does it show anything in device manager.
I was rooted and unlocked, I did the wheele nvflash thing more than a couple months ago. I have also hardware modified my device with external antenna for the WiFi when i got it less than a year ago.
i'm pretty sure i'm screwed but just looking for anything that might help.

This may or may not help but I had it once where my prime would not turn back on.
I took it out of the dock and plugged the power cable directly into the tablet and then held the power button and it powered up with full charge in it.
Yours does sound like a short issue but it's worth a go.

Hi!
I've been having a little trouble with my Motorola Photon 4G this past week. So far it wasn't that bad, but it got worse during the past couple days. I've had it for about 2 years, and have to wait until February to change it. (Note: it is not, nor has it ever been rooted)
It started by just freezing and restarting at random moments. Then I had to remove the battery to restart it when it froze, because the power button wouldn't respond. It started going on reboot loops, where it would freeze, I'd take out the battery, it'd restart, and go through the restart process over and over again until the battery died. I could still turn it on. After a couple days, the battery would drain extremely quickly, to the point where to actually be able to turn it on I'd have to remove the battery, plug the phone in until the "looking for battery" icon popped up, reinstall the battery, wait for it to charge, and then turn it on.
Now, no matter what I do, it will not turn on. If I plug it in a wall outlet, it
-With the battery installed --> LED turns green, nothing pops up, power button is not responsive
-Without the battery --> Nothing happens
If I plug it in the computer, the LED turns white, but the Dual Core screen doesn't pop up. When it rarely does, it freezes there.
I have tried the whole "hold power button and volume down" (Stuck in RSD mode or something like freezes on the screen), or "hold the power button and volume up" (Fastboot freezes on the screen), and the holding the two volume keys when the Dual Core screen pops up doesn't work either.
I can't get a new contract, since I am moving away in a couple months in another country, and an US phone would be useless.
Does anybody have a solution?

Try this:
1) Power down (if not already powered off);
2) Pull the battery out;
3) Plug power in *without* putting the battery in;
4) Boot the phone.
If it does not start, we'll have to go from there. If it does start, you need a new battery.

The light is green because it's powered and the battery doesn't need charging (not in the device). At least we have that.
Ok, this will sound stupid, but let's give it a shot:
1) unplug power;
2) remove battery (if not still removed);
3) Let it sit for a while (10 minutes would be overkill, but what the heck);
4) plug power in (not battery -- leave that out);
5) Press and hold the power and volume-down buttons for a good long time -- get a motorola screen?
If we don't get the motorola screen, could be a couple things -- screen dead? Or hardware prob (maybe the power button is dirty -- push good and hard just to be sure).

i had the same issue 2 weeks ago. you need to buy a new battery as the one your using is completely drained. after that... unbrick and you should be ok.

Okay because I'm just going to have to have everything literally spelled out for me. I wasn't exaggerating when I said I was a noob haha
As I thought, battery shot. Confuses many. So, an unbrick might not be necessary. The battery just won't even pull up the bootloader.
If you get the new battery, and you never rooted, thus didn't load the clockwork recovery hack, it should charge, and then boot might be ok. We will see, but until you see no boot at all, unbrick is the last resort since it's a slog and you're not overly experienced.
I can help, but the OP on the unbrick thread is a great help in most cases.

No worries -- your duty (of course) is hit the Thanks button when folks help and we get somewhere. I also fixed a couple typos in my reply (typed on a phone, and naturally ends up imperfect. Just didn't want you confused. One way or another, you can get the phone back up and running.

Not quite sure what you're saying, but the new battery the OP in this thread purchased should charge fine unless something is really wrong (never rooted so never loaded any charge-precluding mods).
If you are saying that on your phone, with a new battery, you still had to unbrick it because it wouldn't charge ... hmmmm ... seems very strange. Even the clockwork recovery mod would come up and then allow rebooting normally.
We'll see when the new battery comes. Hopefully no unbrick work required, just a charge.
what i am saying is that when the phone is bricked.. i mean bricked... nothing works what so ever except rsd... then thats it... it will not charge the battery. if you have a dead battery then dont expect it to charge while rsd. i needs power on the battery to allow RSD because the computer doesnt flash when the battery is dead and doesnt flash without the battery.
thus... he needs a changed battery. you could buy a seperate charger if you like... but it is much more expensive then buying a battery
Ok, I see what you're saying.
Yes, if truly bricked, it's an unbrick operation. Smells bricked, but I find it plausible the OP gets a battery with enough charge to try a boot. It is concerning we couldn't get booted on power without battery, though. That should have worked. Do it all the time working on kernel modules.
Just saying don't unbrick until trying out the new battery, the former of which the OP could do on power alone.
To qualify so no confusion -- I reboot into recovery mod without battery merely by plugin in -- so I can flash over modules. I've never been able to boot in to the OS normally without the battery in, but we still should see the moto logo.
Sent from my HTCONE using xda app-developers app
I let my m8 completely die last night, and when I plugged it in it is virtually responsive. The red LED flashed twice, and at point I saw a battery with a picture of a charger in the middle briefly, but it is mainly just completely unresponsive.
I have:
let it sit plugged at least an hour.
Tried multiple chargers/cords
Held power down for 20 seconds
Held Volume-Up+Power for 30 seconds
Held both volume keys for two minutes.
Nothing. (annnnnd It may be rooted so I can't send it in)
Any suggestions? I'm starting to see why people keep land lines....
EDIT: Holding down vol-up and power eventually made the red led flash a few times, but then went back to nothingness.
I actually had this happen a few months ago and I fixed it by using adb commands. Can't remember the commands I used as I never really use/had to use adb other than to initially root and install recovery.
A quick Google search and you'll find the commands

adb is unable to find my device (but how would it see a device that is off?)
Google has yielded no results for adb commands without a "connected" device.'
If I unplug and hold volume up to force if off (whatever that means more than it is...), then plug it in to my computer, the red light does flash a few times. First slowly, then a little faster.

A few moments ago, I just turned my phone off, connected it to the computer and adb listed it as connected (solid red light, not flashing). Not quite sure of any other solutions other than hitting up the guys at mobiletechvideos.com. They can probably get it back up and running for 40 bucks. Not sure if they support HTC but they brought my old S3 back to life
EDIT: Another option would be to try taking it into AT&T. Just tell them the damn thing turned off and never turned back on. They may decide to give you a replacement. Wouldn't hurt to try seeing that it's a free route

Try posting/searching over in Verizon. There may be something specific to their software version that is causing this issue. Aside from that, I'm all out of idears. Good luck
Did you try holding down all the buttons for a minute or so?
I had a problem similar to this and I did the method above and my m8 started working, so give it a shot and see if it works
Try charging for several hours (overnight). Then try again with the button combos (power + vol up, down or power by itself).
The fact the screen came on at all (to show battery charging symbol) is somewhat hopeful. Unless the battery itself has gone bad, you can probably get it back up and running.
First of all, sorry if this isn't the right place to post this thread.
Last night i was playing TFT on my Xiaomi Mi 10 as it shut itself down without any warning.
I'm sure i had more than 20% battery left.
This device is about 1 month old, and it crashed one time before, but i could just reboot it with the power button.
This time though, no reaction.
I tried every possible combination of Volume Up/Down and Power button presses, nothing. No vibration, nothing on the screen, just plain nothing.
It literally bricked itself. I did not root it or anything similar, I just used it normally.
Any ideas on what caused this, and more importantly how to fix this? I can't believe this.

Try plugging in your phone to a computer. I had a similar thing happen to another phone a little while ago when out of the blue it just died. I tried charging it, wireless charging it, trying power buttons etc but it instantly fixed itself when I plugged in the phone to my computer via USB. Let us know how it went.

Try different cable or check if the cable you use is working. Then press both volume up, down, and power button for at least five minutes. It might reset the phone. It happened to me once time not on the mi 10 but my rog phone 2 and I press that 3 buttons combination and the phone booted up again. I know the mi 10 might not work the same way as the rog phone 2 but you have nothing to lose to try it.
Yeah I tried using another cable, although I know this cable works (old phone). I also tried charging it via my PC, I even tried to connect to it via ADB, it didn't show up in the device list after installing the drivers.
Pretty sure I'm going to give it to service, I still got warranty and I even have insurance for it.
Because of that I don't want to open it to get the battery out and back in, although I'd really really like to know what caused this. I literally played a game and zap it goes black never to be seen again... I hope the service finds the cause and tells me.
Anyway, thank you really much for the suggestions and the help. Incase I get to know what caused this I will write it here as long as I remember to. Until then Cheers Lads.
Same here. My step-daughter purchased this phone and received it Tuesday morning. Now it won;t respond to anything.
I was handed the phone with "pcsuite.mi.com" on the screen but upon connecting to my laptop the screen went black and now won't respond to anything at all. No Recovery mode, no fastboot mode, no vibrations, nothing.
From reading reports online from other users, it seems like Xiamoi really "dropped the ball"/"shat the bed" with this model

I've also performed "lsusb" to see if the device is alive and there's nothing there either
