Help! Phone won't boot up at all

So, I woke up this morning and I went to go check some messages on my phone, but when I checked, the phone wouldn't turn on. I charged it like I usually did and when I got to it, the blue led light was flashing. Not brightly, but just like it would try to turn on, but it can't so the light slowly fades away. I tried to hold the power + volume buttons (both up and down) but it still wouldn't do anything. Any help before I take it into sprint?

can you charge the battery? is the battery loose? I would take it to sprint and let them check it out.

Yeah. I think I might just take it back to sprint. But it won't charge at all I think.

Pull the battery and leave it out for a few minutes then try again.

I've done that and I actually start seeing the empty battery logo. But It's only for a second. I think there's a problem with the battery or the charger thing

Okay, My phone actually started up now. The battery is not charging though

Just kidding. It's charging. Anyone know if I should be worried about anything?

Are you using an after market charger?

Get a brand new quality USB cable. A HUGE amount of issues can be resolved by just doint this, believe me.

I was using the charger cable it came with but connected to my computer

well your computer USB port can only push 500mA out max. sounds like its undercharging your phone. the stock charger pushes 1000mA or 1A.

Dead Phone - RED LED OF DEATH

Flashed Lifeless last night. Everything was working fine, left the phone charging at 10% then today I wake up to a dead phone. Wont charge, wont boot. Only sign of life is holding the power button down for like 20 sec and the battery LED will turn on for like 20 sec but only if its plugged in. What gives? Anyone have any idea what might be going on?

Plug into a 2 amp charger or do a battery pull.

Same thing has happened to me! I have done a battery pull as well with no avail. I am using a 1.2 A charger, the one that came with my phone and still nothing. I can get the red light as well but nothing else. I have pronounced the Phone as DEAD and have already bought a new phone(funds are tight so it was a was crappy situation). If ANYONE has a real working solution to this PLEASE tell us!(I'd greatly appreciate it)

You held the power button for 10 seconds? Try going to recovery or bootloader or download mode

Similar situation
I'm on stock but had the same problem. Phone totally discharged, plugged it into my car charger, phone got hot by camera but did not charge. Got home plugged it into stock charger, same thing. Battery charging on screen, phone hot, then dim light on screen. tried for a day or so, no luck.
Tried holding power button for 20-30 seconds, nothing, Vol up and down + power, nothing. By accident held power and vol up and charging light came on, held it for a minute, and it stayed on, let go, out it went. As a last resort, put two rubber bands around the phone to hold in power and Vol up and bingo! Charging light stayed on! left it overnight and found the phone completely charged in the AM, green light flashing. Been working fine for days, Willnot let it get too low of a charge in the future.

What the hell is going on with my Nexus?

Just a couple days ago, my power button on my galaxy nexus started to act really weird. When i press it, the screen would shut off (as usual) and then a minute later, the screen would turn on again as if someone pressed it.
Later on, the power button started to have problems. The symptoms included not turning the screen off when needed and pressing really hard to shut off the screen.
And then this morning, the screen shut off and I pressed the power button again. Phone didn't turn on at all. So I took out my battery, plugged the phone with the USB cable into a power outlet, put my battery back in and tried turning it on. Instead of turning it on to the usual Google sign, it went to a white centered battery sign showing that it is being charged.
I tried turning on again, by pressing Power + Volume on the phone. No use. Tried again to take out battery, SIM card even, plugged the phone into a computer and plugged the battery back in. No use. I also left it charging and plugged out my cell/battery to let it rest for 4 hours. No use.
I bought this phone a month ago and it worked all fine until this week. Seriously missing this phone. What is wrong with it? Any help would be appreciated. Thanks.

Sounds like the power button is broke.

Maybe an app recently installed. It can turn on the screen and turn off when the app want, and can freeze your phone. Check your latest installed applications and then tell us...

[Q] Phone Boots when battery is connected then goes black.

First thing is first, I have been searching here and Google and have not found this exact problem.
I am running cm-11-20140719-NIGHTLY currently
Today my phone turned off on its own while connected to a car charger.
Here is what it is doing.
When the battery is connected the phone turns on and gets to the Samsung logo, then it goes black. No back light, nothing. If I pull the battery and re-insert it, it happens again. Once it goes black none of the buttons seem to be responsive (cannot force a reboot by holding the power button). Once it goes black if I connect it to a charger I get no LED indicating charge level.
If I try to boot into recovery I see the blue text and then it goes black.
If I try to boot into download mode I can get to the triangle screen if I am fast and then it goes black.
If I have a data USB cable connected and I connect the battery the phone does nothing, and will not respond to the power button, again no LED light indicating charge level.
If I have a charge only cable (wall outlet) connected and I connect the battery I see the battery charge icon for about 1 second and then the screen goes black. and the phone will not respond to any buttons.
I have duplicated all these things with 2 batteries both actual Samsung batteries, neither of the batteries is bubbled out at all.
I have tried leaving the battery out for several hours, but this did not help.
I have data on this phone that was not backed up so any suggestions I will try.
Thanks

Return to stock with Odin to see if the problem goes away. If not, report back and we will go from there.

I would if I could get it into download mode... The screen will not stay on for more than 5 seconds and ODIN never sees the phone.

Here's a thread talking about that issue. I'm afraid it sounds like your display is dead:

I had this problem before and I was freaking out, but it was just the cord I used when trying to connect it, but yours sounds like an overload problem, maybe from your car charger if it plugs into the car lighter socket. My buddy has a super recharger that hooks into his lighter socket, and while it may charge fast, it might have jolted your phone, or maybe you had it over clocked in your rom? Or was it a recent occurrence or did it happen as soon as you installed the rom? Because this happens on a bad flash sometimes, if your Wi-Fi connection is shaky or far off, you could get a bad download and it will royally harm your time having to mess with it.

If it was just the screen wouldn't I still be able to get into download mode?

I had flashed the night before and it ran fine all night and all morning, then it just shut down. The car charger I use is not a super charger, but it is also not a Samsung charger. I was not overclocked and my wifi is not shaky usually.
Seems like I am screwed either way.

This blows, I just had the Same Exact thing happen last night, word for word.
Although I'm on a stock Rom that's rooted.
Phone was in my pocket and it vibrated as it restarted on its own. Pulled it out of my pocket, waited for it to fully start up, then I could use it.
However, it rebooted 2 minutes later and has Never come back yet.
I wish there was some sure fire way to verify if its the screen that went bad or the logic board. The mere fact the screen shows the Galaxy S4 logo, or Download Mode for a few seconds before shutting off seems weird if the screen was in fact bad.... =(

Check your power button, it could be stuck.

You were correct! Had to mess with that button a bit to get to work properly, but its still an issue. One to many power button presses and the issue returns.
I have tested the phone without the exterior power button only using the logic board button and it did that same thing. Am I correct to assume that the fault is the actual button on the logic board? So new logic board to fix this? =(

Why so many presses of the power button?

Hard brick, sudden death or mobo fried?

This morning my phone was acting funny as usual when all of a sudden I heard a loud static sound come from it. My phone cut off and I haven't been able to get it to come back on.
I've tried a soft reset and taking the battery out for a while, it still won't start.
Is it bricked or dead completely?

Did you try plugging the charger in to check for appropriate level and health of battery? When battery is out, discharge the circuit with power button press and hold.
Does it boot to download mode or recovery?

I've tried taking the battery out and holding the button for 30 seconds. Nothing.
I've got two batteries, both were at 95% before it stop coming on. It's be acting strange for the past few weeks. Shutting down randomly, rebooting into Download mode and freezing. I'm just trying to figure out if I need to get a new phone or can I salvage it.

No recovery or download mode possible after long battery pull? No display lit up with charger plugged in? If no, may be a brick; needs a tech to look at it.
That loud pop and black screen is a bit concerning.
Sent from my SM-N920P using Tapatalk

Yikes, mine just started freezing a lot and it's rebooted randomly a few times.
Fingers crossed I don't have the same issue.

My computer is still detecting my phone when I plug it in. Is that a good sign?

How so? Are you getting into download mode and recovery? Press and hold VOL(-)+Home+Power is download mode. Recovery is same pattern but VOL(+).
Anything on phone display?

Whenever I connect my usb cable to the phone, my computer makes the sound, letting me know its connected. I don't get anything visual on the phone screen or on my computer.
Also, the phone has be getting warm if I let it sit.

No. That's not a good sign. I'd pull the battery and let a tech or engineer look at it. It should be mostly idle if powered down with battery installed. Sounds like it may be in a serious loop or intermittent power switch. If left to its wits end; it could be catastrophic. I don't see it recovering on its own. Needs intervention if any good is to happen.
