Phone will not turn on? - Galaxy Note II General

Hi to start off i went to bed last night and put my phone on charge (with w zero lemon battery) the same thing I have done loads of times before, and woke up to the phone not responding it had the charge led on and that was it, so i removed the battery and replaced it. Now my phone will not turn on i cant get the charge light to show up, i have tried 2 other batterys I have, one is the stock. All i get is the proximity sensor led flashes every 10 seconds, it will also do this if i have no battery but its plugged in. i have tried draining the capacitor by leaving it with no battery and no charger for 30 mins still no difference, I have tried different cables.
i had the latest CWR and was running MIUI
it hasn't taken and falls or anything just recently
could this have something to do with the OTA update?
I was reading about the SDS (Sudden Death Syndrome) could it be this? i hadn't heard anything about this before, is there a fix?
I don't mind opening it up and i am quite handy with electronics and a soldering iron if there is a need/way to hard flash the phone.
any help is appreciated

[Q] Phone suddenly went dead (latest MIUI 2.6.35 kernel)

My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).

[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 powers off while charging and battery is depleted

I have a problem with my Nexus 4. Since about 2 weeks ago, without changing any settings, my phone started turning itself off at night. At first I thought it was the sleep of death issue, but it's not. It does this even with the Safe Charge app installed. What's weirder is that when I wake up, my phone is not only off, but it's entire battery is drained. About 15 seconds after unplugging it and plugging it back in, the red battery indicator light begins to blink, and about a minute or two later, I am able to power it back up.
Charging the phone for short periods of time doesn't have this effect, but charging for hours will do this to it.
I DO have SlimKat ROM installed and its custom kernel... I will try to revert to stock and see if that has any effect, but does anyone know anything about this? I'm worried it's a hardware failure, which is bad news for me.

i can't say for sure but that seems to me your battery has started to die!!
did you find any solution to this?
My nexus had the red light of death some time ago and I eventually bought a new battery. but battery time was still horrible with the new original battery - phone lasted only for about 6-7h with full charge with almost no usage.
I now found out that even when I turn the phone off completely the battery looses it's charge after about 8h.
It's definately a hardware problem - does anyone have any idea what part might cause this and if it's possible to fix it?

[Q] Nexus 4 bricked? Tried everything.

12.
Not everything my friend
Just charge the battery for some HOURS or over the night. All the described symptoms indicate a low battery to me.
cheers
UPDATE:
Just managed to unlock a bootloader in that short period of time i can get to fastboot. But still no change, phone wont stay in fastboot.

Well, i actaully tried to leave it plugged over night. But i think it stops charging right after the red light dissapears, which happens after 15mins or so after plugging. Btw, i mentioned earlier that battery shows 3.7V when measured with multimeter, so the battery doesn't seem to be the culprit... or does it...?

your battery is drained below safe line....to 0%. They warn you NOT to update it with less than 60% battery FOR A REASON!!
Friends case she managed to charge ger asus 7 memopad with non-removable bat to 60% after 8 HOURS, because of a bloatware wakelock drainage to 0% after a factory reset....
If that doesn't work you have to either recharge the battery manually (something like car batteries, you have to unsolder the battery connector because the battery doesnt have 2 gold squares that touch the gold pins like the removable ones, or get a new battery.
Li-Po batteries should never be discharged to 0%, and can make problems if they are not removable (Nexus 4)

I did manage to charge it manually with two small wires and an old Nokia charger, when checking battery with multimeter after a few minutes of charging seems to increase voltage. But i guess if the chip on battery is fried there is nothing more i can do.
I will try to leave the phone on charger all night once again, see if that makes a difference, and update if anything changes.
take off the back, disconnect the battery connector wire and connect it again, put it on charger and see if things change
UPDATE:
Leaving it to charge overnight didn't have any effect. Any other suggestions than changing a battery?
Nah, sorry, but i am out of ideas. You basically tried it all :/

I know there is a lot of threads about bricked N4's, and i can assure you that I have viewed each and every one of them, but i still can't resolve my broblem.
This whole brick situation happened after trying to update to Android 4.3 OTA update, the phone didn't complete the process and turned off, where red light of death happened.
So the scenario goes like this:
If i hold POWER button for ~30s when phone is off charger i only get a Google logo for 2 sec, and phone instantly restarts
Holding PWR+VOL-DOWN buttons when phone is off charger doesn't do anything
Plugging phone to charge (socket or PC) results in solid red light
Holding PWR+VOL-DOWN or PWR+VOL-DOWN+VOL-UP for ~15s makes the red light blink at a steady rate
While continuing to hold the respective buttons and pluging the charger off, and on again gets me to bootloader or download mode (depending on button combo) for ~2s and phone restarts.
I tried removing and inserting the battery 3 times. One time i got blinking red light when plugged the charger in. Second time i got solid red light and third time got solid red light again
I tried charging the battery directly for 15 minutes with old Nokia charger, and it resulted in something different(when i assembled the phone and tried to turn it on with PWR+VOL-DOWN buttons when charger was plugged off, i got to bootloader for 2seconds before phone restarted, i tried to boot second time and the same thing happened, but when i tried it third time i got nothing, just like before) so this was the first time i got into bootloader while not charging a phone.
*My PC seems to pick up the phone for a brief moment when it is in bootloader and starts installing the drivers. Drivers gets installed when i'm in download mode for that brief moment too.
**Phone doesn't get to the white or red battery icon while plugged to charge.
***Solid red light dissapears after charging for ~10mins, but phone won't do anything.
****When measured with a multimeter battery shows 3.7V
I hope someone will be able to help me with this, as it is frustrating as f*ck. I don't have a working warranty, so fixing the N4 isn't an option, and where i live phone repair prices are over the roof (ex. motherboard change for N4 costs ~270$ ).

I had the same problem. Kept it on the charger for a whole day and still only the Red Light.
Took it to a local shop and they said there is a short circuit in the antenna
Took it to the LG Service center and they said my motherboard is gone.
Both were costing a bomb to repair and still there was no guarantee.
IMHO, get a new phone.
Sorry
Have you tried charging it with a wireless charging pad? I got mine to boot after I did that. Your battery is drained and it doesn't have enough juice to charge itself.

Don't fall for the motherboard dead trick. Just a way to steal your money.... change the battery and never let it go to 1%

Battery or Mobo, opinion please!!

Replaced the LCD full screen assembly on my LG G2, all went smooth following a YT video couldn't really have gone wrong,
Switched phone on and battery displayed 0% for several minutes, eventually getting to 2% when I turned it on, all was still OK, however it dropped to 0% within a few minutes even while still plugged in,
Then it was completely dead, no charge light and couldn't turn on,
Removed all of the components again from inside of phone and rechecked all of the connections, again all OK, this time it cam on again!! 0% charging, so I left it charging waiting as long as poss, 45% it was at when I checked but left it while I was sleeping,
Woke up this morning to phone completely dead, cant power on and no charge light showing
Am I wasting my time buying a new battery? could this be another component? LCD?
Appreciate any help,
Thanks
Lee
have now disassembled and re-assembled a further twice and now it does not power on at all
no red flashing light and nothing on display
I've got a similar problem. Did you find out anything? Bought a replacement screen from ebay, and was really confident I could do this, since I earlier replaced the usb charging port with no issues. Of course the battery was discharged completely before this, but I charged the phone and it worked a week ago (which resulted in an annoying alarm that I was unable to shut off because of the broken screen). So after replacing the screen, I plugged it in and turned it on before putting on the back cover. At first it vibrated and I could see the backlight turning on. Then I could see the red led, and thought it was charging, but then the led started to cycle between different colors. I was not able to get a picture on the screen. I then plugged it out and put on the back cover, in case that was needed (didn't seem so from the yt video I used). After that, nothing. Not even a LED. And the phone didn't get any hot like it does when charging/working. It did somewhat get a bit hot the first time.
My first suspect was the battery. It did take some wiggling and force/heat to remove it‚ and it did kind of bend at the edges, but not very much. Any ideas?
