[Q] s4 shuts down seconds after powering on - T-Mobile Samsung Galaxy S 4

I left my perfectly fine i-9505 s4 to charge overnight to find out it did not respond to anything, holding down the power button or power+voldown+home did not result in any sound image or vibration.
Removing the battery and re-inserting it makes the s4 respond to the power button, but the phone shuts down seconds after powering on. This also happens when I try to enter recovery, download mode or insert the charger.
It even happens when I use my usb JIG, the downloading screen appears for a second, after that the screen blacks out again. Tried removing the SD / SIM cards.
The only way I can connect it to Odin for a second (at least as far as I know), is by:
1) removing battery,
2) inserting Jtag
3) inserting battery
4) remove JIG (very quickly)
5) insert USB to PC (very quickly)
Yay! Windows makes the "USB connection" sound, before making the "USB connection lost" sound a second later and the screen blacking out..
What could cause this? Is it my battery? Connector? Software (jamals 4.4v6, faux123, mj5 modem)?

Have you tried directly plugging it into the charger or your computer without the battery?

Thanks for your reply.
Yes, I did try that, the screen does not turn on if I plug my charger / USB cable from PC into my S4 when the battery is removed.
What could cause shutdowns after 2 seconds from booting? I hope this is fixable!

It sounds like there is a physical defect in the device. If it was software related (this can be caused by a borked up ROM or Kernel) you wouldn't see the same behaivor in Download mode and that doesnt' use either the ROM or Kernel.
You could have something physically broken inside the unit that is causing an electrical short once something common to the system and download mode is activated, which would cause the reboot. That could be the USB port that both the system and Download mode will constantly poll the USB port looking for a connection, but only after a second or two. It won't look at the USB port immediately when teh GALAXY S4 splash screen pops up so that's why you get a second of it working. There are 100 other things internally that it could be too.
I'd say make sure the charing port is cleared of any debris. If that doesn't work, I'd say it's broken and needs to be repaired. Without knowing exactly what is causing the issue I wouldn't suggest trying to fix it because you'll cancel the warrenty by doign so and might not find the problem. It could even be a faulty memory chip on teh circuit board that wouldn't look broken to the eye.
Since you can use Download mode for more than a second, you obviously can't try to restore to stock, which is the prefered go to method to fix things like this.

Sounds very much like a hardware malfunction. Without having the device on hand, I can be of no help, unfortunately. If it's under warranty, I suggest you try to get a replacement.

Thanks for the replies. You have convinced me that this is a hardware issue. I have no clue as to what might have caused this defect.
I will soon try a different battery, and if that fails I will contact Samsung.
Unfortunately though, my firmware is custom and this may void warranty, which would suck since the cause of the issue is probably not related to the software.

A day later, the problem appears to have solved itself. I'll keep you updated.

My S4 was working for some time, but the problem returned, the phone shuts down seconds after booting (normal boot / recovery / download mode / USB-Jig induced download mode..)
HOWEVER:
Sometimes, when I connect my S4 to a charger, it turns itself on (first displaying the charging icon) and then starts booting, showing the Google boot animation (since I'm running GPE). This animation keeps going for minutes, and then the phone shuts down again (black screen, does not respond to anything.

You're just delaying the (possibly inevitable) death of your phone. Use your warranty while you still have it. At least I would in your situation.

The symptoms that you have described are those of a bad power button. This happens quite often.

I think you are right! It would explain the inconsistency and the fact that my phone sometimes turned on by itself.

I had to send my S4 back to Samsung THREE TIMES before they realised it was a hardware error. The first two times, all I got was a factory reset.. Which of course, didn't help.
I'm pretty sure you were right, it was a bad power button.

[Q] USB issues - not charging - can't get into fastboot mode

Hello everyone,
having major USB issues on my GNex. It's not charging anymore, but when the phone is off, it displays a charging animation. I could get it to charge once since this occurred, I left it plugged in overnight on my Mac (phone turned off). Did the same thing last night, no charge at all.
Mac OSX does not recognize the device, my Windows machine keeps telling me something like "the connected device is not working properly and can't be used... ". This message pops up every few seconds, so I guess it's constantly connecting and disconnecting. I can't access the internal storage on both systems.
My first guess was a hardware defect. But when I try to boot into recovery mode, a screen instantly pops up that shows Andy and displays a message: "Downloading. Do not turn off target.". In the upper left corner it displays " ODIN MODE" in small red letters.
When I press the power button in this screen (there is a big arrow pointing to the button with "start" written in it) the phone just normally reboots.
I can't get into fastboot mode because of this. I can get into CWM Recovery when i use the reboot into recovery option built in the ROM.
I dunno much about Odin (next to nothing). Has it something to do with Samsungs Kies? Could it be that something has put my phone in this "ODIN MODE" and it constantly tries to download something, making the USB port unusable? The port is not completely broken, as the phone displays a charging animation when it's turned off... so there is some connectivity left!
Thoughts coming up that this could be some kind of software issue. If there is a possibility to get out of the Odin Mode, it may solve the problem.
The phone is unlocked and rooted, running AOKP Milestone 5 and franco kernel.
I tried to restore an older nandroid, but it did not change anything.
Would send it in for exchange, but not able to relock the bootloader due to no fastboot access. If it can be confirmed that this is a hardware problem, I have to pay for the repair, I'm fine with that.
Has anybody any ideas that could be helpful? Any help is much appreciated, thank you in advance!
Do a search and you will find at least 30 helpful threads. Basically you only need to replace your USB charging board and it works again. Should be a warranty issue, but Samsung has really been an ass on handling this issue lately and claiming water damage.
I have mentioned it many times here: this problem can be probably solved by thoroughly cleaning your USB with soft toothbrush.
True, I also cleaned my port but it only fixed it temporarily.
Thanks guys. Tried to clean the port, nothing changed.
Ordered an OEM charging board off ebay, hope changing it will fix the issue.
Only thing I'm wondering about is, that the phone is stuck in Odin Mode when I boot it up with Vol. - and the Power Switch. So I downloaded Odin but it does not recognize the phone...
I am also facing the same problem. I am currently using the phone by charging the battery externally. Can someone confirm that changing the USB flex cable is the solution ?
Just posted in another thread but it is definitely the USB port for me. Using an HTC Vision (Google g2)

Fullbrick?

I got a Xperia S here from a friend, he says that the screen suddenly turned off when he was using it. But the notification bar was on!
So he gave me the phone, because I want to fix it.
If I plug in the charger, no reaction.
Soft-Reset - No Reaction.
Hard-Reset - No Reaction (No Vibrates)
Trying connect to fastboot mode / flash mode. No Success.
My last chance is to remove the battery for 5 min and then look if the battery will charge or not.
The bootloader is unlocked and there was OpenSEMC beta 2 installed.
Is this a Hardware bricked phone, or a software issue with empty battery?

this sounds like a softbrick, there are lots of threads on fixing such issues, i seem to remember 1 problem was switching off auto lighting and bang the screen goes blank, holding the power and vol up/down for about 15 seconds makes a hard reboot 3 vibes, then plug in via usb and restart with flash tool running might work. there are lots of different help threads that will guide you through this. dont give up.
But Hardreset doesn't work. I already tried it.
Read this : http://forum.xda-developers.com/showthread.php?t=1849170
Thank but I read already this thread.
I can't remove the battery right now, so I asked you guys if this issue is a Software issue or Hardware issue.
If I can remove battery I will test everything I can and then I'll report.

i think it's hardware issue. cause for it to be software issue it must at least show red led when plugged into the charger.
bring it to service center is a wise choice. but u can try different charger (with bigger amperage output is preferable), and what happen when u plugged it to PC? did the led color shows up?
If I connect to my PC nothing happens.
No Fastboot Mode no Flashmode possible.
I remove the battery the following days, cause I don't have a torx 6 to remove the screws. Must buy one.
Removed Battery and insert it back again. Now trying to charge but no reaction.
If you plug-in a Real charger(Not pc usb), what happen?
Sometimes when the battery is full empty, you have to keep it charges about 15-20 minytes without powering on

Put it in the real Charger, and charged 30 minutes.
But still no reaction. I guess it's a fullbricked Phone now.

[Q] Not quite sudden death - but still a major problem

So I recently installed CM 10.1.2 on my S3, and everything worked perfectly for a few days. Yesterday though, my phone started acting strangely (lag when turning screen off, registering phantom input, etc) and began rebooting every few minutes. At some point, it ran out of battery - and now I can no longer boot past the CM loading wheel screen.
I can't boot to recovery, and I don't think my phone is taking charge (from my computer or a wall outlet), and the farthest I can get is the loading wheel - sometimes it only gets as far as displaying the Samsung logo, or the Galaxy S3 screen with the android dude at the bottom.
I'm still covered under warranty, and would love to take it to the store for a replacement (I've had battery issues prior to this), but the fact that it can get to the CM loading wheel means that they might figure out that I've rooted and whatnot. But I can't get to recovery to flash a stock image, so...what can I do?

Your best shot is to either borrow someone's S3 battery or buy a battery pack. Use that to restore your phone back to stock (unroot) and then you can go to the store for replacement.

So turns out battery isn't the issue, I used a wall charger to get it to full charge. I can get it to the download mode confirmation screen, and can press volume up to confirm - but my phone reboots soon after that.
Recovery isn't really possible either, I can see the blue text in the upper right but my phone reboots after that as well.
My phone will often show an empty battery icon with a little refresh icon in the middle; does this indicate that it doesn't see the battery as charged (even though it is)?

Yeah I've been doing some research into the issue...
I've noticed that my phone automatically boots when I put the battery in, and that it'll do a quick vibrate when plugged in to a power source (outlet or computer) but won't turn on.
Apparently the phone isn't supposed to boot automatically when the battery is put in, and this could be the source of the random reboots - I think if I can get the rebooting under control, I'll be able to get into download mode and fix it all. But I'm not sure how to do that. Maybe the power button has gone bad, as it also doesn't usually respond when I try to use it to turn on.
If there is a problem with the power button, does anyone have any ideas on how to fix it?

Mine does the exact same thing where I have to pull the battery and when I put it back in it automatically starts up and when I go to download or recovery it turns off before I can do anything
Sounds like power button issue.
I was having the same issues (random reboots, boot loop, powering on when battery put in, reboots in download mode and recovery)
This is not an easy fix. I ended up pulling the power button out and just setting my screen to time out after 15 seconds. Sucks but it works now.
If I ever need to turn off or hard reboot, I stick a pin in the power button hole and push down on the button.

[Q] Help - Glide crashes and restarts

I bought a Samsung Glide i927 phone last month in the US, i bought it unlocked as i am from argentine, and i wanted to use it with movistar.
Recently the phone started to crash a lot, by that i mean that the screen starts going white, with horizontal lines and pixels of different colors appearing, then just turn off or restarts itself, only to crash again as soon as it starts an then turns off.
When this happens i try to start the phone and select the shut down option myself to see if the next time it starts it doesnt crash. But sooner or later it happens again.
This problem its happening too often, and not while doing something in particular like running an app or something. Sometimes it crashes just by plugging it to the power adapter, it even shows the white screen with the lines instead of the charging battery image when i charge it while turned off. I have already try to fix it upgrading android or doing a factory reset, but that didnt work.
Anyone have any idea of how to resolve the problem, or if its a hardware malfunction that cant be fixed?
To make things more difficult, as i said earlier im from argentine, and i cant go to AT&T or Samsung to get it fixed or get a replacement. English is not my first language, so please forgive my orthographic mistakes.
Thanks
This really sounds like some hardware problem, but to be safe, learn how to use Odin and use it to revert your phone to completely stock condition (cleaner than factory reset).

I tried to do that, but the first times when Odin try to reboot the phone it just freezes and i have to unplug it. After many tries it finally finished, but the phone keeps freezing and crashing.
The phone even crashes while turned of and conected to the power adapter.
Do you think that with LiteROM 0.9.0, that might fix this issues?

Power button issue
I am having a similar problem. At first, it just happened on rare occasions. However, today, it started doing it repeatedly. The phone was unusable. I did some checking around, and it appears that the power buttons on Samsung phones are prone to sticking. Some people suggest you actually remove the battery and slam the power button against a table. I wasn't going to do that, because I could just see it doing even more damage. What I did instead was firmly tap the power button repeatedly. It seemed to unstick the power button and allow the phone to function again.
Another alternative is to have the power button replaced, but that might be a hassle.
First of all, sorry for my bad english.
I bought it on amazon a few days ago, I have the same problem...
I thing aznemesis is right, because my power buttom is very sensitive, in fact, some times, when I press the button smooth and fast, to turn off the display like, the typical menu appears as if I had pressed the button for much longer period. Which proves your theory. The problem is if I hit the button over a table and the button breaks here in Chile do not exist spares of the terminal
Well, I did. I couldn't stand the desire to do so. After nearly 18 hours, the terminal isn't rebooted again.

The horizontal lines on the screen sound as if it is an overheating issue. What were you doing before your phone shut off? Are you using the factory charger?
cure found
take the battery out...blow on the power button with some compressed gas to get the dust out....then pour a drop of silicone based lubricant on the power button so that most of it gets in the gaps...then hit the power button a few times....haven't had any reboots since then

[Q] SM-T700 Froze, Powered off - Soft bricked?

Hey guys,
Appreciate it if you could spare me some advice on how to proceed.
So I was watching a twitch stream and all of the sudden tablet froze, and the audio froze as well causing a large super high pitch noise, I hard-reset the tablet but instead of resetting it just turned off, I started to browse the forums and found that a combination of (POWER + VOL UP & DOWN + HOME) would reset the tablet,now what this did for me is turn the tablet on but it was stuck in SD CARD Mode, back again to the forums, read that letting it discharge fully and then it will be able to be charged and turned on, that worked tablet was back doing some various tasks no video again and then boom freezes again same symptoms except this time I couldn't get it to go to SD CARD Mode its very finicky after trying at various times in the day I finally got it to work, same process except this time as soon as it turned on I went into recovery factory reset it to stock, worked a bit longer this time only installed chrome, and it froze again (don't think it was chrome) , rinse repeat and I flashed the latest firmware with ODIN worked fine, I've gotten to the home screen ran through the "factory new" set up and it turned off of me again.
I plugged it in let it charge, came up with battery icon 5% 10% ect, then I left it for a while, I came back and I cant even get it to show the battery percentage(tap power) let alone turn on.
I'm fairly sure that eventually I can get it turn back on but from there I don't know what to do.
TL;DR - Tablet Froze, Hard Reset, Froze again - Rinse Repeat, ODIN to latest STOCK firmware, tablet worked for 5 min before turning off again (plugged in), present situation
Any ideas as what to be causing the freezing and how I could remedy it?
Also sometimes when it froze it turned itself off without me hard resetting it.
Thanks its been driving me insane,
Please do not hesitate to ask me to clarify or provide more information so I can help you help me.

I had the loose battery connector problem, but the symptoms do not sound the same as mine. I could get mine to boot up, but the screen would flicker and a few white lines would appear before it would reboot itself. I actually started a ticket with Samsung and got the packaging label but, upon further reading, realized that I was pretty much SOL after tripping knox, and didn't want to risk the chance of getting charged for just sending it in. If it is indeed the loose battery connector, you should be able to remove the back cover yourself and fiddle with it. Ultimately, mine needed re-soldering, and I was able to find a local electronic repair shop to do it for me for cheap.
Good luck!
UPDATE: I've managed to get into SDCARD MODE yet again, except discharging seems to get out of it, but once I plug it back in it doesn't come up charging it just black screen, until I hold some buttons and arrive back at sdcard mode. Good times.
Trying various things to get it to boot..
EDIT: Appreciate the insight Squez, I want to exhaust all the other options before opening it myself, if Knox didn't void the warranty to some degree, opening it up should put the final nail in the coffin.
EDIT2: Good news, sort of, tablet isn't dead! after numerous attempts with charge SDCARD mode, discharge, It finally start to charge properly and I managed to get it to boot, worked for a few hours then I left it to charge, and went to sleep, woke up and wont turn on again, but I am in SDCARD Mode again but need wait for it to discharge from presumably 100% ....
[What do you mean Sd card mode? DOWNLOAD mode?
Also no need to let the battery drain.
Just press VOLUME DOWN(not volume up) and POWER together then hold until it restarts.
This is a hard reset and will ALWAYS work unless the device is hard bricked. It is the equivalent of a battery pull.
I continually see here and there incorrect information regarding key combinations, even in so called guides, this forum is even guilty!
Here is what works on the 10.5lte, as far as I'm aware its the same for all versions, indeed pretty much any Samsung device.
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
DOWNLOAD MODE:
HOME - VOLUME DOWN - POWER.
Hold until the device boots.
RECOVERY MODE:
HOME - VOLUME UP - POWER.
Hold until the device boots.

I should of posted a photo earlier but here is one I found on google of same screen: (check attachments)
Except UP KEY and DOWN KEY don't do anything, its just this screen, if you attempt to hard reset ect, it will just reload this screen, hence the discharge, then plug it back in and hope it begins to charge "battery icon appears". I have gotten it to boot like this a few times.

Yeah its strange as.
I'll have a look at that, thanks.
EDIT: It just finished discharging and now I am on the battery screen.. Usually once it charges here I can get it to boot, what I'm curious is what on earth keeps causing it to freeze up, because in download mode and twrp (gone since i flashed stock via odin) it wouldn't freeze at all, only have issues with it once its booted or charging. I installed a logcat earlier hopefully that should shed some light on the situation,
EDIT2: Well another very interesting thing, the official Samsung charger wont charge it, only works if I plug it into pc or use a non-official charger, strange thing is nothing is wrong with the samsung charger or cable since I can charge my phone fully from it. These have to be some of the strangest symptoms.
EDIT3: Only works through USB port on PC for now, non official charger comes with red X on battery once booted. I assume you can work around this once rooted but that's for another time..
EDIT4: Charge through pc to around 2-3%, boot device, plug into official samsung wall charger and it begins to charge properly.
EDIT5: Hooray back to step one, trying get into SDCARD Mode, same thing happened left it overnight and it wont turn on or charge anymore.

i am pretty sure the HOME - VOLUME DOWN - POWER. puts the 10.5 into the sdcard mode.
my tablet is doing very similar to sunb3ar findings.
have had it come back to me once from sdcardmode.. (let if go flat and starting charging then it would start via normal buttons)
it crashed not long after that. it got stuck in sdcard mode again, but this time none of the drain flat, put on charge has worked.. just blank..
fyi- we try to put it in RECOVERY MODE, but it does not work when in this crashed / sdcard mode state
i even disconnected the battery and then plugged back on charge.. nothing..
today i tested the battery volts, 2.8v , for a 3.8v i thought that was ok. i attached my RC lipo multi charger set to 1amp 3.7volt charge, direct to the - + on the battery- got it up to 3.5v, plugged back in, put the charger on- the sdcard mode (most life it has shown in a week).
still not coming up with 'battery' display to say its 'turn-off and being charged'. just the sdcardmode might disappear and return..
i am currently adding mode charge to battery... will try to HARD RESET next.. since i have not tried that combo yet..
HARD RESET:
VOLUME DOWN - POWER.
Hold until the device restarts.
edit: i took it off 'direct' charge, battery at 3.7volts.. then plugged in normal charger, i got a 'battery symbol' but it had the lightening bolt, not a %.. so i unplugged and reconnected to my direct charge to give the battery more volts. i am surprised that the unit seems to think a battery with 3.8volt as it specs seems to not be like with volts not much lower than 3.8.. could be time for a new battery if we can get this thing to restart
