[Q] Galaxy S4 Won't boot (even download mode) - Galaxy S 4 Q&A, Help & Troubleshooting

Hello, my s4 turn off yesterday, i think it's a battery problem but when i connect the charger (usb or energy) the phone wont charge.
so i think it's a battery problem, i test with other battery and the problem remains.
The Led won't turn on and if i plug out the battery and plug on the device start, but turn off on firs samsung logo in a second.
If I turn on in download mode or recovery mode, the device turn off in a second too.
Its strange cause the device start, but not remain on for 1 second!

It's probably your power button that is hanging/broken.

YEP!

How to power-off (for real)

I just received my DHD and as soon as I inserted the battery, it powered on by itself. I plugged in mains for a long charge cycle (I don't want to use it while charging).
I want to power off for real but it seems that when I press the power button even for prolonged time, it just goes to standby. I want to charge it while powered-off. How do I do this?
I didn't have the chance to play with Android before so here I am asking easy questions I guess.
Try with this:
Tap the power button on the upper side of phone for few seconds, then you will see on the screen new window with three possibilities - power off, aeroplane mode and restart. Choose power off. Then you can charge your phone.
Other possibility - work/play with your phone till the battery is fully drained and the phone will switch off itself.
Hope this helps.
Regards.
go to settings applications and disable fast boot

Thank you all. That's what I was doing but I guess that the screen was locked and it didn't work. As soon as I unlocked the screen and performed this procedre it worked. I just didn't want to start working with the phone until it is fully charged and that's why I was trying to switch off without entering the phone.
If you don't disable HTC Fastboot you phone isn't really off, just hibernating.

Good point but I had to go through all setup steps until I am able to configure this setting. Anyway, I was planning to leave the phone charging untouched for several hours but I guess that wouldn't be possible.
My phone boots back into clockwork recovery even when fastboot is disabled.
Apparently the DHD uses the recovery to display the charging LED (orange or green), so when you replace the recovery with CWM attaching the charger when the phone is off will start CWM.

Does your S4 (9505) turn on while charging in off state?

Hi,
I noticed that if my phone is turned off and charging, it won't power up when I press the power button.
To get the phone to turn on, I need to disconnect it from the charger, turn it on, let it load, then plug it back into the charger.
Is this normal? It just seems a bit strange to me....
Cheers
Why don't you charge while it's turned on ?

By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue
ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.
it boots up on download mode for seconds and then powered off again....
Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?

[STRANGE!] Screen won't turn on at all. Can get into Download mode. Screen stays off.

As the title explains, I can get into Download mode but screen wont turn on. I flashed Prism Barebone KK ROM and it's been like that since that. Luckily I know how to get to Download mode without the screen being on. I am flashing stock KK I grabbed from Sammobile right now but what if it doesn't work? Prism ROM does have that no bootanimation bug.
It's not a battery issue, I have 3 stock and one extended battery thats fully charged. So def not battery.
Okay so it flashed the stock ROM through Odin. DIdn't restart on it's own. I let it be for a while, it was connected to laptop, assuming my screen may have died I thought when it gets into OS I'll hear a beep on computer or Odin would detect it, or device manager. Nothing.
So I hit power while USB was connected, the boot logo came on (the Galaxy S4 words) and it stayed there for about 2 mins and turned off i think. Now the power button is unresponsive. I am gonna keep it plugged to the wall.
For reference, I downloaded "I9500XXUGNH2_I9500OJVFNG1_LYS.zip" from Sammobile. [Yes I have the i9500]
Edit/Update: So the phones screen goes on and off with boot logo WITHOUT BATTERY INSERTED! How strange is that........

Out of curiosity, when you insert a charged battery in your S4. Does the device immediately vibrate? If you were having issues with your power button, you would feel the device constantly vibrating because when Samsung S2 S3 S4 power buttons go out, they are usually stuck in the on position. It is extremely rare to have a power button stuck in off.

Power button doesn't seem to be an issue but it's unresponsive. No the phone doesn't vibrate on battery plug.

Nexus 10 bricked-Help Please

i was able to unlock the bootloader and flash custom recovery in fastboot mode. Suddenly, the screen flickers for few times and tab shuts off. Now its not turning on, power, vol+ and vol - combination not working, it only shows battery icon, when I plug in power cable and then it goes off. I am dreading that the tab might be bricked. How to fix this?
Flat battery? see My Nexus 10 will not power up!!!

I am having the very same issue as paindoo and it was the battery. Thanks peterk-1. It took a while until I got the best moment to plug-off to power-on (strange work-around) but now it's charging. Battery too low to boot long enough to say if it powered-off during flashing and something is lost but it's not bricked.
Wish you good luck paindoo that it's only the battery for you as well
