Dead battery boot loop ?

Tried to turn on my nook this morning to be greeted by a empty battery with electric bolt icon. I plugged it in to the stock charger and it goes into an endless boot loop that I cant pull it out of. I've tried booting to recovery and holding power till it shuts down.

I left it on the charger for a few hours now it sticks on the skateboarding android with the spinning arrow. Booting to recovery takes me to a blank screen.

sounds like you should probably do a reinstall if you cant even get that far.. You should be able to keep data and just reinstall your rom through cwm on a bootable sd card. Worst comes to worst, just start over, but that should do it for you...

Don't know if this helps or not but I had the same problem the other day after falling asleep reading. After letting it charge for about 4 hours I checked it and got nothing but the same screen and really thought I messed something up with my cable so called for a replacement. Figuring what the heck, I left it to charge the rest of the day thinking I couldn't use it till I got the new cable anyway. That night I checked it out and it was charged. My cable is messed up (can't connect to the computer with it) and it does take a bit longer to charge but at least I can use it while waiting for the new cable.

Having similar issues
Everytime I accidently let the battery die. I have to re do the manual nooter which I loose all of my apps and the info on them. At first I thought it was B&N doing their force update but my Nook today still says 1.2 so I guess it didn't update.
The Goof

I think at some point my boot sector got corrupted (probably due to low voltage) and had to make a boot disk to reinstall CWM followed by CM7. Everything runs great now.

I know this is Old but thsi is the Solution
When the nook gets below 5% charge it does not have enough juice to boot up enough to check the battery status.
I don't know why putting cm7 on it causes this issue but it just does not know it is low to display low bat and go into idle to charge.
Instead it tries to start up as normal and sucks the little tiny charge it got in a few seconds up and causes it to deplete the battery.
and it repeats over and over.
The answer is if you pull the battery out it resets it's last known battery state to 0% and will no longer try to boto but instead displays the low bat logo and then idles to charge as normal.
So you need to open it up and pull out the wire that connects to the battery, wait a minute for good measure and then plug the wire back in and put everything together again.
the next time you plug it in you will see low bat and it will shut off and stay off and start charging as normal.

[Q] Nook Simple Touch not responding?

This was what happened - my N2T went dead, and I charged it up to 100%. It has previously been rooted with TouchNooter, and since my market wouldn't open, I overrooted it with TouchSalsa. Or so I remember. It may be different. I just remember that I used 2 different roots over each other. Didn't think anything would happen...
Anyways, all was fine and dainty with the N2T till the day the battery's charge was depleted. Charged it to full - Battery Indicator went green - and then proceeded to unlock it.
It was still responding at the lock screen, but once I unlocked it, it went straight to my Android home screen, and it just hanged. It has been showing the Android homescreen for quite a while now (probably due to the static e-ink screen, I believe it has died for a long long time), and nothing I do will make it reboot. I thought about forcing the battery out, but it was not user removable.
n2T-recovery wouldn't work too, as I can't make it reboot.
Any answers as to how I could make it rebott and/or restore the firmware like how I could force an iDevice into DFU mode?
Any help would be appreciated, as I imported this device into my country and it is not possible for me to send it back .
If anyone has encountered this problem before, feel free to shout out here too. My Nook Simple Touch has died for around 2 weeks now. I was hoping that the battery would run out and I could charge it but.... the battery indicator STILL shows green when I plug it in.
Also, whenever I plug it into my computer, the connected sound that happens when you plug in a USB drive just sounds - followed immediately by the disconnect sound. This happens in a loop until I plug out the Nook.

Try disconnecting the battery (by opening the nook) ...

Same issue, i already open the cover and remove battery, the screen still display screensaver. Then I plugged NT into wall charger , then removed (to try make it reboot). Plugged battery into again but , plugged charger . But nothing happened, still the same.
Any other solution?

Just a hint: It appears that the Nook won't boot without the battery in.
I don't know if it's an interlock with the temperature sensor on the battery.
The chip that does the power management is capable of powering a CPU with a dead/shorted/missing battery.

Guess no one had a similar issue?

It is the same with my NST. It was bricked when I root it back to factory restore. The battery light is green, do everything you did to the battery, still no respond. I am not in the US so I can not take my NST to the local B&N store.
I get my NST only 1 week...
PS:Finally I get my NST back following this thread

Dead Nook Touch Fix - showing green light on charge

Thought I'd pass this fix along.
I have a rooted nook that would not power up (stuck on last display screen). When I'd plug it in -- it showed a GREEN light (already charged). I tried all of the reset fixes (20 seconds hold, 1 min hold, wait a minute, 15 secs) -- nothing worked.
Finally, I pulled it apart using this tutorial on Youtube:
[Can't post link because I'm a newbie --- just search for "How to Take Apart a Nook Simple Touch"]
Very easy to do if you have a T-6 torx driver. I unhooked the battery. Held down the power button (white button if disassembled) for about 30 seconds to discharge the board. Then hooked the battery back up, reassembled, plugged in -- and it started charging (orange light).
It looks like the issue was -- the nook was registering the battery as fully charged -- and it was completed depleted. The above fix seemed to reset it.
Hope that helps someone.

I thought that too, but -- at least with the torx set I have, t-5 was too small.

Had the exact same problem and your procedure fixed it! Thanks!

I also had this problem this afternoon. This procedure worked for me too. Thanks a lot because it helped to revive my reader.
However, for Nook to have such a problem and we need to fixed it in such a complicated way is not acceptable.

Fantastic. I had the same problem and now it is solved. Thank you.
After I bought a Nexus 7 my NST was resting for a while. Now, when I wanted to use it again, it was totally dead. Then your tip bring it back to life.

Thank you. When plugged, instead of "Charging (AC)" my nook was showing "Not Charging" in device info/battery. And in the end, it went dead.
After your fix, it works

That's the ticket

THANKS!
Just the tip I needed! :good:

Thanks!
That seemed to work
It's now showing the "Your Nook's battery charge is too low to power up. Please wait 15 minutes! screen and a loading animation :good:
I was seriously worried.
This is really weird...is there any reason for this issue?
I am quite new to the nook in general. (Nook simple touch glowlight in my case.)
Maybe we can check for similarities and find what was causing the problem.
So what did I do to my Nook:
Rooted, Nook Manager
Nooks gapps flashed, market downloads work (search not)
Installed a bunch of apps
Installed a custom Launcher (Lightning Launcher)
Installed Swiftkey as a custom keyboard (needed several language charactersets)
Left Wifi turned on all the time
Used the feature to restore the glowlight setting after being woken up again
Used the setting to skip the lock-screen swipe
Used a custom screensaver/lockscreen text
Changed button links in the main menu (n-button) to adress the original home, as well as the custom launcher home
That's what I can remember :/
And as far as I can remember I had more than 15% of battery (at least).

With the 1.2.1 software there is an automatic shutdown that kicks in at around 20% battery.
It doesn't work very well.
It will also give you warnings when it's under 20% but plugged into the wall and charging.

Green light issue, fix not work
I recently got a brand new nook simple touch and after trying various fixes to try and start my nook up I came across this. I was hoping this would work but it is still on green when battery is plugged in and charging off mains. The light is also green when plugged into mains without battery attached. It wont go past the "Fully charge before first use" start screen and can't find any more information on what to do.
Any help would be greatly appreciated.

Thank you for the fix. It worked the first time I tried but after only one day the problem presented itself again and after that the fix doesn't seem to work anymore. I'm leaving the battery disconected a few hours in addition, to try if it fixes this problem completely (but I'm not too optimistic).

This firmware, does it still count even if you have rooted the device? If so, do you think a downgrade to 1.1.1 would fix the problem? It is rather funny that I didn't have this problem until a couple of days ago, even if my NST is only 2 months old!

Update:
It seems that my battery is not yet dead after all. It turns out that I was measuring it wrong (thank you Engineering degree) and now it reads 4.15V as it is supposed to.
So, that brings me back to the theory that there is something wrong with my software. Right now it can boot for a few seconds but as soon as it goes to sleep mode (either by clicking on the "power" button or just waiting), it freezes. I recovered the official firmware and the problem persists.

Thanks, this trick fixed mine too!

Does anyone know if this fix can be achieved by simply charging the nook for an extended period of time? I have the exact same problem but I'm not so sure about opening the back cover as it voids my warranty and I only purchased this device in early June, and the problem appeared by the end of June :/
I have to confess, I never did charge my nook fully when I bought it as recommended, and simply dived in to using it as soon as the battery had a sufficiently high enough % as I was too excited lol

I find it acceptable. After all, if we weren't messing around with the devices in the first place, we wouldn't ever need to do this.
Plus, really, it's not that complicated. A couple of screwdrivers and it's open. I mean, should we expect it to open itself with a voice command or something?
Anders

Thanks, this method worked ok with mine.

HI dudes,
it seems I've got a similar problem, green light on usb and stuck on "YOur Nook has turned off completely"
I take it apart with no success ... any idea ? Mu NST is nearly brand new, ever used a lot ...
thanks

I had the same problem, the reason was completly dead battery. After bat replacement nook works great!.
When battery have to small voltage, noow won't start to charge. You can try with external charger, to bring battery to life.
I think some nooks was matured in stock, thats why battery was completly discharged...and wont charge with nook.

Nook showing green light, main board drain and nothing
My Nook shows the green light when plugged in either to the pc or wall charger. I've held down the button twice for 30 seconds and disconnected the batery holding the power button 30+ seconds. Neither worked. Any more suggestions? I do notice a slight flicker of amber whilst holding the button down with the power cord plugged in.
Any help would be greatly appreciated!

[SGH-I337 AT&T] Unmodified, Stock SGS4 boot loops, freezes, graphical bugs HELP!

Hello everyone!
My parents contacted me asking for help with some phone issues that I thought would be minor but this is now something I have to submit to you guys because I just don't know how to tackle this issue;
I've got an unmodified, completely stock AT&T Samsung Galaxy S4 that has been owned since launch. My parents were initially complaining about how the phone stopped charging and wouldn't turn on. I thought, "Easy, dead battery, it's been 3 years so how could it not? It might not be delivering enough voltage for the SoC..." but i'm not sure that's the full story which is why I want your guys' opinion since this place is a wealth of knowledge.
Things that are known:
When you charge the phone, the basic "battery charging indicator" that is shown when Android is not booted into or powered on freezes, or sometimes does not detect a battery so does not even turn on. Doing battery pulls seems to change how the phone responds. This is what my parents were experiencing. I thought, either dead battery, dead micro-USB cable, AC adapter, or charging circuit within the phone. Since this was obviously a big job, I took the phone back home for this weekend to play with and now this is what i'm experiencing.
So I got the phone to charge using one of my AC adapters for some reason, despite using the supposed broken charging cable to transfer data successfully without corruption using my own phone (LG G2) to confirm if it was just the cable. So now the SGS4 has a battery that is 100% charged, I turn on the phone and tried various methods to get the phone to boot successfully back into android. The first obvious one was to boot into safe mode using PWR, letting go of PWR, and then pressing VOL UP. It booted ONCE or TWICE successfully into safe mode into android, it shut off after 5 seconds being into the system due to low battery. This was BEFORE I was able to successfully charge the battery to 100% with my AC adapter but has failed to boot since.
Now since I've been failing to get into safe mode as when I boot the phone up, the phone freezes or has graphical glitches at the Samsung post/splash logo as seen here:
After some desperation, I considered using KIES/Odin to reflash, but mostly I tried going into download mode to see if the phone would even go into it by doing PWR + VOL DOWN. It did get into download mode but it froze/restarted forcing a battery pull and ever since then I keep getting occasional error messages such as "System software not authorized by AT&T has been found on your phone.", or this screen with a Samsung logo and an open padlock. I notice sometimes that when I'm at this open padlock screen, it sometimes begins to boot into the system but quickly freezes when it plays the boot jingle:
At any rate, I ordered a new battery but I fear this might be EMMC corruption or just something I don't quite understand. The phone has valuable information that I have to recover despite my parents CANCELLING a backup of the phone, they failed to heed my due diligence and are now freaking out about the data (photos, contacts, etc). I just need the phone to boot so I can make a nandroid backup, export the contacts, transfer media off the phone and wipe this thing and start anew. However i've already let them know that it might not be possible. The most important thing is to get this thing out of this soft-brick?
Please help because I have no idea where to steer this ship from here on out aside from waiting to receive that new battery and hope these instability issues are caused by low voltage. I had an SGS2 which had the crazy EMMC bug so I'm hoping its not EMMC corruption.
Thanks for your time everyone! I'll update this thread to reflect new information as I play around with the phone.
Edit: Here is a video, I go through a lot of the same information posted in this thread but here it is.

Possible loose connection inside the phone? Was the phone every bumped, dropped, or exposed to moisture?

Not that I know of. I'm going to check the water damage stickers if I can to ensure that's not the case but i've been told it was sudden. It had been dropped once before but had been working fine for quite some time up until recently.

Maybe the effects of the drop and manifesting themselves now?

Samsung S4 VE I9515 wont turn on

Hello,
So let me give you a brief so you'd know everything - a few days ago, I'm gonna call it day 1, I walked under light rain with the phone in my pocket, it worked until the night of
Day 2 - started to lag a bit, it was like I was running some heavy apps and like the ram was insufficient. Restarted the phone, everything seemed normal.
Day 3 - Phone went off while was browsing. So I have to make a note here. I was running cm13 with android m and twrp 2..something and there were occasional reboots by itself rarely prior to Day 1. Also, I was using a supercharger (or whatever it is called, it is a charger that charges faster) for about a month.
So when the phone went off while I was browsing, it started by itself and stuck on the android loading. I restarted, cleared dalvik and regular cache - still stuck on boot. Flashed many times, changed the recovery to twrp, and still was stuck on rebooting and occasionally it didn't turn on. There were random occurrences of errors on flashing roms, which never happened before (for example, "cant mount system or data"). Within the time passing by, the phone started not to turn on when I tried to. By this time rarely got stuck on the first boot screen saying with the text "Samsung S4". Yesterday, Day 4, the phone never turned on, except one time. I don't remember doing anything special. I just pressed and held the power button and it turned on, but went off shortly after the android boot animation appeared.
Also there was times on Day 3, when I was trying to boot into the system, it got stuck on the android booting animation.
On and prior to Day 3, while I was charging, whenever it is on or off - I had the indicator light for charging. Now when I plug it in to charge - nothing happens.
To skip any unnecessary questions, I will make a short QA.
Q: Did you tried to boot into recovery/bootloader?
A: yes, nothing happens
Q: Any sign of life on adb while connected to a pc??
A: no
Q: Is battery dead?
A: I don't think so, but actually I'm not that sure. When I connect a separate led light to it, the led lights up Whatever, if it was a faulty battery when I plug the phone on the charger, it should've worked fine.
Q: Why don't you just buy a new phone?
A: I was planning to buy a new one, but after just 4 months when I have to renew my contract. I don't want to buy a phone off contract.
Q: Are you stupid, if you can't manage to fix it by yourself, why don't you give it to a repair?
A: I truly believe that the professionalism of repairers doesn't exist in my country via old experiences with them.
So in the worst scenario I will loose time by trying to fixing it and for 4 months I will use my old android phone.
In the best scenario, my almost 2 years old phone will revive.
Also, I have a multimeter - I can check the electricity. Just tell me what to check.
Thanks.

Probabily the rain damaged a part of your hardware. Did you solve?

If the battery is dead, the phone won't work.
The battery needs to have at least a bit of charge in order for the device to work, even if it is plugged in.
If the battery can't hold the charge, and the device uses more power than it gets, it turns off. I speak from experience.
These devices don't seem to work without a battery. Power goes to the battery, and the phone takes the power from there. Power doesn't go straight to the phone.
Anyway, I don't think a bit of light rain hurts the devices, especially if it was in your pocket. I walked through rain with my device in the pocket many times and no problem.
It looks to me that the hardware is failing. I don't believe that a faulty battery can cause a bootloop. I also don't believe that the power button causes a bootloop.
What I suggest would be:
1) Try going back to stock ROM.
2) Maybe try to get an S4 with a broken screen and switch the motherboards.
