7.7 Down for the Count

Used my device last night to do some reading and the battery was about half full.
Went to use it tonight, won't turn on. Thought something killed the battery, so charged it for an hour.
Held power button, nothing. Tried volume up then power, nothing. Finally got it to do something by pressing volume down and power. It comes up to the Odin screen.
I've never rooted/loaded any roms or anything, so anybody have any idea what the heck happened or how to get my device back to normal?
Thanks for any help.

Have you used the stock AC wall-charger to charge it up?

Yes, it's charging now while I am reading all about using Odin and downloading a stock firmware...
Not that I know what I'm doing <grin> I'm hoping it powers up after I charge it some more before I go mucking with it...
Thanks, Samsung! I'd much rather be having this fun instead of reading a book. Where is the damn ICS update? Honeycomb sucks.

I would let the battery go flat which is the same as removing the battery on a phone and hope that allows you to re-boot normally after charging then I would try a factory reset to clear any problems before going down the re-flashing road.

Well, looks like letting the battery go flat is my only option because after charging all night it now won't even go into Odin Mode.
Do you have a general idea how long it will take for the battery to die since there are no indicators? Should I expect days/weeks?
Sure wish I could pull the battery or use the paperclip trick like on other devices. This thing is a very expensive (imported) paperweight right now.
EDIT: Any idea why I couldn't get to the boot loader (volume up + power) to reset the device but the Odin mode worked?? I don't think it's the button, this device has been coddled. Just sits on my nightstand until I read a little at night and put it back.

Uh 九千., I'd thank you twice if I could.
So I go to pull the usb cable and wall charger behind my nightstand to bring to work and it's NOT the original charger. I forgot it came with the European power adapter so I had to use a generic USB charger.
I grabbed the Samsung wall plug from my 8.9 and now it shows the battery with a yellow exclamation mark. I'll try charging it and go from there.
Very strange, considering I've been using the other usb wall charger since I bought the device maybe six months ago...
I'm hoping for the best!
EDIT: IT BOOTED and it's charging... What a relief. Thanks for the help guys.
EDIT 2: So before, it was NOT charging... It got so low that only the Samsung wall charger could get it going??? Very strange.

dead

It appears dead. It's late at night so i've yet to try googling about recovery through a pc of some such, truth be told while i can flash a rom with instructions, i'm no guru or anything. It was running CM 10.2? the latest stable release for N10, think that's the one.
I was just browsing a forum, and after posting, the disply started to stutter as i scrolled up, when i stopped scrolling, the stuttering decreased, and then as i scrolled and scrolled fasster, the stuttering increased until display turned black (stoned curiosity...) and now i can't get anything out of my N10. Holding power, trying to reboot into recovery. Nothing. No lights, sounds, vibrations. None of the normal stuff.
anyone got any ideas for me to awke up to? I think that if i can't get any life out of it, then would it be a case of trying to sideload or such with ADB? as i say, i'm a complete rookie, just a couple of flashes under my belt.
Second question, i probably have the answer to, but am i right in thinking custom roms void the warranty?
edit: Plugged it into the wall a few minutes ago. It had had about 40% remaining, but when i plugged it in, i got the battery simbol on the screen (big white battery charging in center) and any time i press or hold the power button, or with volume buttons, i get nothing but the icon. I'll keep it plugged in for now and see what happens. But by the look of i assume if it can do that when plugged into the wall i sohuld hpoefully be able to connect via my computer in some manner

If by stuttering you mean blinking, this has happened to me when my N10 was on charger with a dead battery and it drew more power than what the charger could provide. When you scroll, the CPU frequency gets bumped up and the tablet consumes more power. After a while it just turned off for me (when I changed to an other app I think), when there just wasn't enough power.
So I would suggest leaving it on charge for a few hours, then try holding all buttons and see if you can get into bootloader. I've had the battery levels not display correctly on some custom ROMs, (for example I would do a reboot at 60% battery and after it reboots it only said 13%) so just charging it a bit might solve the problem.

Thanks. As of 5 minutes ago it got back to life. All battery apps showed 40 odd. Strange.

i think your battery has gone/ on its way out, exact same happened to mine, you need a pogo charger and the original wall adapter to provide enough power to switch it on. Only thing which worked for me, hope it works for you.

Might be the battery, might be glitchy software. Plugged it in via USB and it worked sometime later. Will be keeping an eye on it.

It will probably be fine. I thought I had a bricked N10 but turns out the battery was dead. It is fine now. THought I had a bricked N7 also, turned out the battery plug got loose, (screen would flash every 2 seconds with static on the screen) popped it open and oushed the plug in and that is fine now too.

If it continues to die around the 40-50% mark, you'll need to send it in for repairs. Make sure they don't just try replacing the USB port on it, the battery itself is the culprit.

[Q] n4 is completely unresponsive (dead)

So this is what happened:
the phone discharged fully and i connected it to charge. then i got a flashing red led. seeing this as a bad omen i tried to turn my device on - no luck - it wasn't responding.
i unplugged the charger and plugged it back in and again the same result, then again..... and i got a solid red light. so after a few times of messing about with it , trying out a few sources of power and such i got it charging (the battery logo appeared). The charging lasted for ~30 sec and it went black.
So after that the n4 is completely unresponsive. No flashing leds no backlight on screen, NOTHING.i tried out a few chargers and cables and beside those i used a genuine n4 charger (it's 100% working - i tried to charge another device). i left it there for the whole day to charge thinking that maaaaaby the battery ran to a complete 0 and i just need to give it time, as you probably guessed it, that did nothing.
In fact, i think the phone is not charging at all. The reason i think so is because the wall charger is emitting a faint high-pitch squeal regardless of the fact that the phone is connected (it should be squealing only when it's plugged into socket and the phone is not plugged in it)
so TL DR:
n4 is completely dead, no signs of life. The things that were tried:
a handful of chargers and cables that are 100% working on other devices
trying to boot with a combination of volume buttons pressed
holding the power button for 60 sec. while plugged in
prolonged charging (~7 hours)
verbal threatening to sell the damned thing if it's a serious problem
so that's that. i should get my tools back from a friend on monday. i'll try to take it apart, maby there's a loose connector here or there or something. Any ideas what i could try before that?

Some searching around the forums wouldn't hurt. Try this for example.

thanks for the link, that seems to be worth a shot.... i'll be able to take the phone apart on monday, that's the earliest i will be able to try it. i was wondering if there is anything i can do until then to remedy the situation. I mean i'm really getting a kick out of my old sony erricson k300 but i kinda prefer the nexus and would prefer to fix it asap.

ok i fixed it
i used a 3v source and held the contacts manually for 5 min. that returned it to the red blinking led state and after leaving it to charge for 5 min it returned to the battery icon on screen. thanks for the info again.

Nexus 4 Dead ( Hibernation mode? )

Hello everyone.
3 days ago, I was charging my nexus 4, I checked and it was at 80%, and after a while, I rechecked it to find it dead : no boot, no charging icone, nothing. Even if im familiar with this problem (happened to me once before I replaced the battery), I tried different methods to resolve the issue : pressing volume down and power button and plugging charger or usb cable million times, letting the phone charges over night, charge it on computer, taking off the battery and trying to charge it seperatly (saw a thread on this forum), nothing happened, just a blinking red LED whenever I press volume down or up and power button over 10-15 sec and plug it. I even checked the battery with a multimeter and it emmites voltage, so I think the battery is good (1 and a half months old).
Please help me with this.
P.S: the charger used when the phone died was a faulty : if u touch it or expand (till tight) the wire, it stops charging, and u have the press the head tight so it goes back to function, and the one I used for testing all I said above was a good one.

did a new post, dont know how to delete this one --"

No1 to provide any help? Come on XDA !

[Q] Red Light - Charging without back?

So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.
