"N" screen keeps flashing on and off - Barnes & Noble Nook Tablet

Had it plugged into PC with no problems. Left, came back, the N logo keeps coming up, going black, then back up at 12 second intervals. Unplugging it causes the screen to go dark and I can't power it up. Plugging it back into the PC causes the n screen to start cycling again. Help?

We need more information in order to help you.
What kind of modifications have you made to your NT?
Custom kernel, custom ROM, new bootloader?
What recovery do you have installed? Have you accidentally formatted or erased anything recently?

Not sure I have all the asnwers but I'm running cm7 alpha, no customization beyond repartitioning. No accidental erasure....it was working fine, I walked away for an hour, came back, and there it was...
when it's connected to my pc it makes the sound as if it's trying be recognized every time the N comes up...repeats

I would try to see if you can boot from an SD card. Either a CWM bootable card or a CM7 card.

I had the same thing happen recently. If the problem is the same - mine was low on power and I didn't get it on the charger quick enough - take out the SD card and re-plug the tablet. For some reason this worked - I think because it was looking for something it couldn't find on the card. This allowed me to charge up normally.

Ironically the night before i ran it down to 0% power for the first time ever. Wold not allow me to power up until i charged it next morning. I will try powering up without card, as powering up with cwm bootable did not work.

Just making sure here, but did you try booting from your CWM SD while plugged into a power source?

A full night charge got it back up and running. But as a follow up - I took out my card with CWM on it, and when i powered it up without it , it still booted up into CWM. So I assume I have it installed internally (must have done that before and forgot about it). Put card back in, did a reboot from CWM and it came up fine in CM7.
is some tweaking in order here?

Maybe reflash CWM to your recovery partition. It may have been a bad install the first time.

Is my phone bricked?! (grey battery screen)

Hi guys,
I figured I'll post again here since I think I bricked my phone.... I was trying to install Eugene's Vibrant6.zip and I got stuck on the Vibrant Logo with Samsung at the bottom. I tried to reset with both volume buttons and power button and got to grey battery and nothing else...
What I did prior to this was I formatted system and data on the recovery screen as per some posts here and it would just boot into a loop. Windows won't recognize a device and it just shows grey battery image and it doesn't seem to be charging. Anyone can help me?
EDIT:
Out and in the battery, plugged in to USB and it just loads the battery image and it's all grey color as if fully discharged and just stuck on it. Device is also not found in my system so I can't do any adb commands. If I just reset it without the cable it would just sit on the Samsung boot loop. Anything I can do?
UPDATE: Ok, some good news! I heard the sound as it connected via USB, I can see the 2 drives, but they read as Removable Disk and I can't access them...
adb reboot recovery or download
error: device not found
What if simply format the drives via Windows right click menu? Will that do any good or bad? What are my options here? Any help will be appreciated!
UPDATE: Well... looks like this is pretty much a dead phone.... I right clicked and selected Format in My Computer and it just says There is no disk in Driver F: Insert a disk and try again.
Can I a mount an image somehow via MagicISO? Or is there something simpler that I just can't figure out?
Again, thanks for your help!
Thanks.
Has anyone experienced this or am I the only one?

Sorry I have never heard of this or witnessed it while flashing anything to my device. Obviously the battery screen signifies that the phone is off but is in charging mode and hitting the power button will boot the device up. (I'm sure you already know of this). Never heard of it being stuck at that screen after flashing. Hopefully you can get this solved soon. Good luck

Slow down for a second. Your phone is definitely not bricked. Ive been over the edge, and been able to bring my phone back to life.
To clarify, you flashed vibrant6.zip through clockwork mod, and then the phone got stuck on the samsung S? How long did you let it sit there?
It sounds like just your ROM is messed up.
Are you able to "get into recovery"? Holding both volume buttons while you power on the phone, without it being plugged into usb.
Do you have Odin? And have you ever used it?
Its totally frustrating when your phone gets messed up and you don't know what to do.
I flashed the stock ROM via Odin and then wanted to install Vibrant6.zip. For that I entered into a recovery mode via Clockwork and as someone in the other thread advised, I formatted system and also data, don't recall exactly. Then it looped to a standard recovery mode and I just rebooted the phone. This is where it got stuck... Vibrant in the center and Samsung at the bottom of the screen. To test it I left it like that from night till this morning. In the morning I woke up it was on the same boot screen.
Before that at night, after seeing it hand at the boot, I held both volume keys and power, waited for it to reboot, and immediately it showed a circular progress bar, but not moving just highlighted the 12 o'clock bar and second later I see the battery image all in gray and nothing else. It just sits on that grey static image without actually charging it (no green section or flashing dots)
Boot logo only appears if I am trying to reset without the USB cable. On the boot loop I plug in the cable and I hear the USB connecting it, I see the 2 Removable disks, but both inaccessible and adb commands don't recognize the device.
Very weird, as in turned off mode it's not charging at all.. just shows this grey battery image with a circle progress froze on 12 o'clock bar.
That's pretty much it.... I was never able to enter into recovery nor download via the buttons. It would just always reboot into this grey battery screen....
Completely helpless.... I did order a new battery from TMO, maybe the battery is fried and that's why it's not charging and just sits on this stupid static grey battery screen.

Holding both volume keys and releasing power once screen goes blank, only show Vibrant logo again... I have tried this a million times
With USB cable it shows grey battery screen, without the cable just a Vibrant boot loop...
I'm assuming that you have the Samsung drivers installed.
Try the following steps:
Take out the battery and then put it back in but don't turn the phone on.
Plug it via USB.. does anything show up on the screen?

Yes, I have the drivers installed as I was able to locate my device and use adb commands to enter into recovery and download. Also Kies worked.
Doing what you asked simply load the grey battery image and nothing else with a progress bar not spinning. Just sort of hangs on this image and that's all.
Booting without the USB cable loads the Vibrant boot loop. Connecting USB at this boot loop state, would play a sound as if it connected to my windows, but I can only see Removable disks that are inaccessible and adb doesn't find the device...
Very strange.... trying to use the button keys to enter into recovery or download is no use, as that just won't ever happen, even when phone was working fine.
Any other suggestions? I would return the phone for replacement... but I am not sure how it would look with all the files still on the internal disk including root if I am not mistaken... I had only few hours of sleep because of this headache

Are you sure that you're doing the right things to get to download? I've been in this situation and I wasn't able to get into recovery but I was able to get back into download mode.
I believe if you return it back and they find out it was rooted, they will charge you for it. If not, it'll appear on your bill.
I'm sure that you're doing the wrong things to get into download mode. If something is appearing on your screen it is a soft-brick and you're not bricked.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen (powers on its own when plugged in)
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

A tip to get into download mode is to put the phone HORIZONTALLY (sideways) and it will make it a lot easier.
I am pretty much positive about it. I know a lot of people can easily enter into recovery or download modes, but I know many can't and I am one of them. It would just load the grey battery image instantly as I let go of the power button.

3. Plug the phone into your PC, do not hit the power button! DONE
4. See if the phone shows anything on the screen (powers on its own when plugged in) FIRST THING THAT APPEARS IS A CIRCULAR PROGRESS BAR THAT CHANGES TO A GREY BATTERY IMAGE WITH A BAR IN THE MIDDLE OF IT. STATIC IMAGE, NOTHING ELSE.
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.

THE STUPID GREY COLOR BATTERY IMAGE APPEARS AS BEFORE....
I'm thinking maybe battery is fried and that's why the grey color screen appears and not the usual screen where you see the battery charging...
After reading this thread it's clear that my handset is one of the new ones that have recovery/download modes disabled via the volume+power buttons.
So that pretty much covers it... I hope TMO will not ***** about the files that are on the internal sd that I am unable to access and remove... unless anyone else has any fresh ideals how to gain access to the disk
I think I might have a similar problem.
I accidentally deleted the touchwiz framework so I can't do anything ON the phone. It boots up, and gets me to the lock screen. As soon as I unlock, I am greeted with dozens of unending force closes.
I can get into both download and recovery mode, however, I have not been able to get ADB to recognize the device. I am attempting to push the stock ROM to the internal memory to flash over everything.
I'm not sure what to do to get ADB to work but it's driving me nuts!
Stuck at vibrant? I have a fix
Check out android Dev Section... I figured out how to access download mode or stock recovery mode when you are stuck at the vibrant screen!!!! BACK IN BUSINESS VIBRANT OWNERS!!!

I can't get into Recovery or Download and computer won't see phone to Odin.
I've got drivers installed and AIO Toolbox as well as ADB(which won't work because of computer not seeing phone.
Using the manual option(vol+ vol- power), nothing works.
I've done all the tricks like unplug it then hold vol keys plug it insert battery..
When I do plug in the phone to to even just get a charge in it goes the the battery, but my is is frozen or something. doesn't turn green or have a charging animation. After about a minute or so it was start up and boot loop. I read something about a bad battery? I've got two of them and they seemed fine before..
Before all this I had to Odin and go to stock. I was attempting to get ics back but I was being lazy and trying to do as little as possible..bad idea. I was following slim ics install and flashed cm9 daily, slimics and commons..and now this..

Try asking another question. But I suggest using a USB jig. They usually work. Then odin
Sent from Mount Olympus via Hermes
Did you ever get it fixed man? I literally did the very same to mine a while back and It works like butter as we speak. It is fixable with a mini-usb jig or dongle. You can make your own with about $3 worth of parts from radio shack but I recommend buying one, it will be easier. I for the record made mine simply twisting together the resistors and though it was tough to touch the right pins it did eventually work and get me back into download mode.
Hopefully you already got it fixed though. If not I can help you out.

My Amaze refuses to start up

My Amaze has been off for about a week or two and now it wont even power on.
If I press and hold the power button I get no indication that it is doing anything. However, if I press the buttons on the bottom of the screen I get a slight vibration indication that it is indeed getting power to it. Tried booting into recovery with no luck.
Any thoughts?
What recovery are you using? I know most recoveries don't support charging while off. I suggest 4EXT but you will need to charge the battery externally first in order to flash it. Good luck.
do you have an external battery charger to charge the battery out of the phone?
did you try to charge the battery ?
Here's an interesting update.
Was able to plug it in USB and using ADB restart into recovery. From recovery I hit restart and the phone booted up like normal.
BUT, about 5-10 seconds in Android it reboots again back to the black screen with the vibrating buttons. Had to run back to work so I wasn't able to play around with it anymore than that.

if your running a custom rom maybe it got corrupted somehow, happens to my phone often due to the fact im trying to find a way around to cloning one rom to another phone, try to reset your phone back to stock by flashing a ruu stock rom or a different rom, flash 4EXT and wipe everything from the phone (including sd card) don't forget to check and realign the partitions and then toggle usb mode and put the rom on the sdcard and flash it , hope that helps

Battery pull, hold volume down(or is it up? I work on too many android phones..) and power button and it should boot into bootloader. From there reboot into recovery. Flash a custom rom of your choice after doing a full wipe. Problem should be solved unless there is a hardware issue, at which point it must have been dropped, battery issue, etc..
What it really seems like is your battery doesn't have enough juice to sustain power, (I get bootloops when my battery goes really low and I try turning it on). Just let it charge a bit and if the battery isn't holding its charge, then time for a new battery

xperia p no charging lights, no usb detect,does not boot (not even the kernel screen

hello everybody,
i used to be active on the x10 forum.
but recently i switched to xperia P.
i unlocked the bootloader,
used fastboot to flash custom boot.img,
fastbooted custom kernel (FreeXperia),
installed cm10.zip with the CWM included in kernel,
everything works except wifi and bluetooth (which i guess is the rom's fault, so i dont really mind)
and then i installed apps from the cm10 file manager.
it detects my 16gb internal memory.
but my titanium backup and some other apps says it cannot access my internal memory, so it doesnt show any apps. (usb is disconnected)
so i thought mayybe some apps dont have access, so i thought i should mount my internal memory (although it already works for my cm10 file manager).
that was a very stupid decision because i used this code from this website which i got after i googled and used it on my terminal emulator.
guess what happened? my device got stuck/hang/frozen.
then when i pressed the power button, it was totally blank, no response and the screen went off.
i tried force shutdown by pressing and holding the volume-up & power button at the same time for a long time, that didnt work either, it had no effect, there was not even a vibration.
and when i charge it, there is no charging light.
it doesnt boot, it doesnt show me the kernel screen, or the CWM screen.
this is worse than a bootloop.
anyone who has previous experience with this?? or has a suggestion on how to repair?
any advice will be much appreciated :crying:

I think you've posted in the wrong forum - should be in Q/A.
Is your phone able to detect in flash mode? (while it is off, hold DOWN volume key and connect USB - check for LED illuminated)
Is your phone able to detect in fastboot mode? (while it is off, hold UP volume key and connect USB - check for LED illuminated PURPLE)

Hi.
1. Have you tried to charge it through the charger, instead of the usb por of PC?
2. If you tried, did you let it charge for at least 30 minutes? (Sometimes the battery drains so much that the phone needs time even to show it´s charging.)
If the battery charges, you should try flashing a Stock Rom through Flashtools.
If it doesn´t, then I can´t say you should do it but if I were in ur position, I would surely open my phone and try to charge this battery somehow. Google a lot to learn how it works, the wires, what is positive and negative and bla bla bla because your biggest problem NOW is not having power to work with the phone.
Hope you have good luck!
=)
Sorry please post your thread at Q&A

i have reason to believe it maybe related to the battery. maybe the battery is still running. how do i physically shut it down? the holding power button and volkume-up button trick doesnt work.

1. Have you tried to charge it through the charger, instead of the usb por of PC?
2. If you tried, did you let it charge for at least 30 minutes? (Sometimes the battery drains so much that the phone needs time even to show it´s charging.)
If the battery charges, you should try flashing a Stock Rom through Flashtools.
If it doesn´t, then I can´t say you should do it but if I were in ur position, I would surely open my phone and try to charge this battery somehow.

Use this guide to open the phone up and just disconnect the battery for a few minutes. Then try connecting in either fastboot/flash mode. The phone may need to be repartitioned and reflashed.
Same issue
Hi Davin-J
Did you finally solved this problem? I have the same now. And my battery should be good.
...............................
1/2 day later:
It was the battery. I managed to get it back to life as copper62472 told us. The strange thing was, that the Sony charger didn't charge the phone battery; may be because I bricked the phone before with system/data/cache wiped and formatted. I was not even able to restore it with SUS, because the phone was not detected at the USB.
Then I charged the battery outside the phone with a current limited power supply. After putting the charged battery back into the phone, restoring with SUS worked without a hitch.
Help

My xperia p is also in dead condition now. I'm thinking like it's battery is fully drained. It all started with flashing of a custom kernel.
i could take the battery out. i need to charge it by external means. How can i do that? Please help me.

[Q] Nook Tablet Won't Turn On or Boot from SD

So I attempted to root my NT using Ray Waldo's Jelly Bean & Root for Nook Tablet 1.4.3
(here's the link so you know what the process was: http://raywaldo.com/2012/09/root-for-nook-tablet-1-4-3/ )
and I got as far as booting the NT from the SD card that contained CWM recovery on it, and it began the process. It then decided to just shut completely off after it seemed to be either almost finished or finished with the boot process. Either way, the problem now is I cannot turn it on. I have used every button press combo, as well as several attempts to boot off of recovery SD cards. I have tried connecting the NT to the computer via usb while holding down the power and home buttons, and all that jazz. No matter what I do, my NT will NOT turn on for ANYTHING. Although the battery seems to be fine, since after plugging in the power cord (after attempting to press buttons or whatever else) it turns orange for a few seconds to a few minutes (depending on how much I mess with it) and turns green. I am starting to think that any method that uses the SD card to boot into recovery or flash to stock or anything is simply not going to work, as my most recent attempt was to boot it into Ubuntu Recovery using Adam Outler's [UnBrick]TOTAL WIPE and reflash back to 1.4.0 via Ubuntu Recovery --Now Easier!!!! (here's the link: http://forum.xda-developers.com/showthread.php?t=1470910 )
and after following the instructions for both Ubuntu AND windows, the card will not make the NT boot into recovery. Considering Adam Outler's method is supposed to completely set everything to 0, I am pretty sure that anything regarding booting from an SD card is NOT going to work.
Is there any way that I could connect the NT to the computer and fix it through that? If anyone has any MEANINGFUL and USEFUL tips regarding this dilemma, PLEASE help me out. I am aware of the possibility that my NT could be fried beyond repair, but at the same time I can't help but think that there's GOT to be a way I can fix it. I don't care about saving anything on there, or what ROM I flash it to, or anything like that. I just don't want to be a paperweight anymore. I would like to at least figure out why it won't turn on, if nothing else.
Like I said, I have already tried several methods regarding booting to recovery through the SD card, and none have worked. Again, NOTHING is making it turn on at all. Please help me!
I would try the repart.imgdecribed here http://forum.xda-developers.com/showthread.php?t=1663836 before attempting anything else. I think your trouble stems from TWRP, but either way, try the repart.img before you start messing with anything else.
I know you say it's impossible to boot from sd card, but I still think it's worth a try. Insert the card. then insert powered charging cable. If it still seems dead, hold power button for 10 seconds. Remove and reinsert powered cable.
The fact that the charging cable is green does not automatically means it's charged. It just means it's not taking any power, and that could be because of whatever makes it not turn on. I think it may not actually have been dead when you thought it was at first, and then it could have drained completely. It needs to get some juice, so try keeping the chargging cable inserted when experimenting with buttons.

[Q] Tablet turns on when plugged in

I'm running this unofficial cm 10.2 rom, and I'm trying to use the sony flashtool to go to back to stock. Unfortunately I can't complete the step where I turn off my tablet, then plug in the usb cable while holding the flash key (volume down), because the tablet automatically turns on when I plug in the usb cable.
I know I'm not doing anything wrong because I've done this before. At the time I flashed stock while running the official cm 10.1 rom. What can I do to fix this problem?
EDIT: I forgot to mention that when it automatically boots everything is very laggy. This lag is gone when I manually boot the normal way.
EDIT 2: Don't ask me why, but when I deleted the clockworkmod folder from my micro sd card, the automatic boots stopped.

jup it´s a bug. the sony chargemon (the battery that showed on stock when you plugged the tablet in while it was turned off) isn´t included in cm10.x . the lagginess is caused by the governor which switches to "powersave" if the tab gets started by the charger (you can change it back to "interactive" in the performance options)

Probably, but all I know is this: I tried four or five times to plug in the usb cable without it automatically booting. Then I do one thing (deleted the clockworkmod folder), and the automatic boots stopped. I tried doing that after I read how someone fixed his automatic boots by deleting a keyboard app from his removable sd card.
I dont know but why not try to use SUS if you want to go back to stock.. it will delete everything though..
Are you using Emma?
