[Q] Boot problem I can't seem to find a fix for

I've seen a few people with the exact same problem around the web, but no one has ever posted a solution (if they ever found one).
The kids were playing Angry Birds on the Nook before dinner, when I went to turn it back on after dinner it wouldn't boot (was working when I put it down).
When I plug it in the wall charger the light is always green.
When I plug it into a computer USB port it is momentarily detected as omap 3630 instead of Nook Color like it used to, then windows reports that it's been disconnected.
It had been running CM7 for a few weeks off of emmc, but now I can't even get it to boot from a uSD card into CWM.
When plugged in (computer or wall charger) I can see the backlight turn on and off every few seconds.
No combination of button presses seems to have any effect (power, power+n, power+n+vol+, etc.)

Try holding the power button for a full minute... release and try turning it on again... see if that don't do it.

Thanks for your reply.
I wish that worked, but I don't even see the back light flicker on for a split second unless it's plugged into the wall or a computer.
It's a shame too, I got it as a Christmas present from the wife and our toddlers really loved to play the games on it. They keep asking where "bad birdies" went

Your problem sound similar to an issue I had with charging. I has a bad charger/usb cable. Its a known issue and BN will replace it for free. If you are registered, call BN support a request a new one. I have done this twice. Once when the end bent and a second time when I had a green N but not juice (just flicker and/or a 'plug in the charger' symbol). The NC requires more power than the typical usb charger/cable setup, thus spares usb chargers AND cables around the house do not work.

I hate to do this because it was so maddeningly frustrating to see the same thing posted in the thread about boot problems here and elsewhere, but it turned on today and I have no idea why.
I'd been messing with it for a few days and finally after an unsuccessful morning I left it on my dresser. I was in the kitchen making hot chocolate after playing in the snow with the kids when my two year old comes walking down the stairs with the nook and drops it at my feet. When I went to pick it it, it was in the process of booting. Whether he had done something to it or the short fall jarred something that was loose I can't say, but it now seems to be fine.
It had about 50% battery and the lights on the charging cord now respond like they should.
I have no idea what happened, but I wish I did so I could help others in my boat.

Still could be your charger/usb cable. When the charger/cable start going bad, it takes for ever to charge. Like all day just to get enough juice to boot up. If it dies again and doesnt reboot after its been on the charger for a few minutes or you're only getting a partial charge over night, its the charger and or cable.

It charged fine overnight.
There definitely must be something loose on the inside. If I give it a fairly significant whack (nowhere near a punch, but harder than a tap) it will reboot. I think it was a refurbished unit. The newer units seem to have serial numbers where the first four digits correspond to the year. The first four digits of this one are 2004! Looks like they never fixed what was wrong in the first place.

You just ran it too dead. It won't power on until it's established a decent charge first.

Atrix Black Screen

So Im a proud owner and enthusiast for the Atrix 4G (original only I cant stand any of the others released they did it best first time around). Ive had this phone with some minor problems for over a year. For a while the phone would randomly reboot in my pocket so long as it wasnt doing anything. If I were playing music on the device it wouldnt reboot but the second I stopped the music, put it in my pocket, and pulled it out it would be powered off. I reset the phone to factory (I had a flashed rooted rom on the device) and the problem stopped.
Now about 3-4 months later I made a phone call put the phone in my pocket to pull it out with a black screen. Now I thought the phone just died was all so I went in and plugged it in to the factory wall charger and to my surprise the LED came on and the phone chirped that it was charging. So it was actually still powered on. I tried looking at the screen from all angles and shined a light on it but there is no picture to be found anywhere. Otherwise the rest of the device (to the best of my knowledge) is still working properly. I could confirm this by my alarm going off in the morning and my in-ability to turn the alarm off due to a black screen.
Also ive pulled the battery, allowed the device to die, and have tried several chargers and other batteries I have so its not a battery or power issue. The screen also remains black on boot, you know the device is powered on once it boots into the OS and chirps that it has service.
Ive dis-assembled the phone to check all the cables in hopes that it would be a simple fix such as a loose cable however everything was double and triple confirmed to be plugged in and locked in place.
I had allowed the phone to die and waited a day or so with the battery pulled out once it had died and then plugged it in and allowed it to charge before powering it on for 30 minutes still to no avail. Ive even tried hard-naving to factory reset and still have had no luck.

I would like to purchase your dead phone for parts.

To me, it sounds like you have a broken LCD screen.

Droid/Milestone 2 does not power up

Hello.
This is a long shot, but i'm going to ask it anyway...
Some years ago I owned a Droid/Milestone 2, that decided to die apparently.
After a bit of searching, I decided to purchase the XT1058 I currently use and forgot about the droid.
But I've found it again lying around, and tried to start it with no success...
On its finals days, if for some reason you needed to reboot the phone, it would take some minutes for it to power up again. Once it was up and running, it was just fine.
Until some day, minutes became hours, hours into days, and the phone never worked again. While it was in this state, nothing appeared on the screen.
It was just dead... And then, after a minute or so, after pressing the power button, it would boot up and everything would be ok.... until the next reboot at least...
Now, if I connect it to the USB port, the white led on the side stays on. It's not recognized by windows nor RSD, but if you leave it like that, Windows makes the sound of an USB device connection, a few seconds pass and the sound of usb desconnection appears. So there seems to be a bit of life (not much)
I cannot charge the battery because when I connect the charger, white led by the charging port is not on.
It only stays on if I remove the jack just a bit, so it's not fully seated. I do not think it's battery related since when it died I tried different batteries...
Holding the power button does not do anything...
Question is, do you see any hope on this enterprise?. Idea would be to have this as a backup...
Or should I just throw it away?.
Thanks in advance.

Nexus 7 won't charge/power on/can't access fastboot or bootloader

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.

Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

I'm currently having the same issue, haven't used it in 6 months and when I tried to turn it on, nothing happens

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec

same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........

Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.

I would be more than happy to take it off of your hands mate. Probably gonna use it for parts to keep mine running.

My 6P died..

So yesterday when after finishing work I grabbed my 6P from my desk and wanted to check for notifications. To my surprise it was off.
I held power button for 2 minutes - nothing. Tried holding various button combinations, still nothing.
I went home and plugged it in charger overnight. There was no reaction and phone did not seem to get warn while charging either.
This morning I took it off charger and tried turning it on again. Nothing. No reaction.
Tried plugging it into computer, nothing new in device manager. Booted up linux and tried there, same.
After all that I just took it into repair shop. It is theoretically still under warranty, but there is a little chip on right side - in plastic between screen and frame.
Does anyone have any idea what could have happened?

Try 4 to 5 minutes to hold the power button, while on charger. 2 minutes are maybe to short.

Yea, I tried holding while on power and while not. Once I held it for 10 minutes (my finger started to hurt lol). Tried Holding power and them plugging in the charger too.
Anyway, does not matter now. It is in warranty service already.
Was just wondering if anyone else had a similar issue.

Happened to me on a trip outside the country. Pulled it out of my pocket and it was dead, wouldn't take a charge, looked completely dead. I bought a burner phone and planned on taking it apart when I got back. Three days later I plugged it in and it charged up and started just fine. I have not had it since (3 months ago). I figure there is some hangup internally and the battery needs to deplete completely before the thing switches off completely. Let it sit for a few days and try again...

So.. The local warranty service basically said that they won't repair it because it is 'physically damaged'.
Which is crazy.. Phone is in perferct condition only 'damage' is between the screen and metal frame. You know, that little plastic edge.
See attached picture (sorry for quality).
I now have emailed Huawei directly explaining the situation. Let's see what they respond.
I will leave the phone unplugged for few days to see if it comes back to life.

try plugging it back into the charger. mine came back from the dead with the red charging led after the mentioned recuperation period. I let it charge a while and switched it back on. No problems since.

I had the same problem. Send to hauwei and they changed the phone. The sad part is the data I lost.

I will leave it alone for few days and then try to charge.
I sent an email to Huawei UK, which is where this phone originally came. Let's see what they respond.
See the attached picture, I made a better one.

Had this two months ago. When connecting it to a pc some weird qualcomm entry popped up in device manager, basically telling me something was very wrong.
Sent it in for repair and got a new motherboard even though it was unlocked and had a custom ROM
But i guess they couldn't check that as it was completely dead
