I have a T-Mobile Samsung Galaxy S3 with a slimkat rom, its been working normally for a long time until recently. At first it would shut off by itself randomly when I was on the go with battery power still available. Now it wont even get past the boot screen. Its not bootlooping software wise, but more hardware wise, as in I turn it on, the samsung logo comes on, then when it shows slimkat it just dies. I cant even get into recovery mode, and when i get into download mode it does the same thing, is the the faulty power button issue? I cant test if its the battery because I dont have a spare but I do notice when I remove the battery and plug it into an outlet/PC and test it out it still doesnt power on, even with a battery in too, so I dont think it has anything to do with the power source. Any suggestions or guesses what it could be? Anything else you guys would like me to troubleshoot?
It could be a power button issue. You could remove the outer plastic button (this requires disaasembling the phone) and then try to boot.

A few days ago I looked at my phone and the 'Device Options' menu kept appearing over and over as if someone was holding the power button down. I managed to turn off the phone and since then I haven't been able to get it to reboot. The phone will boot to either the 'SAMSUNG' or 'Samsung Galaxy SIII' logo screens and then the screen goes blank. I can occasionally get the phone to start booting into recovery mode but it turns off before getting to the menu, same thing with download mode. This seems to be getting worse as well, as the first few times I tried to get to recovery mode I could at least get to the menu before it turned off.
The phone will not charge either. I can get the charging indicator (red LED) to come on if I remove battery, plug in USB cable then reinsert battery. However, the battery does not actually get a charge when I do this.
I have tried swapping in fresh batteries, removing SD card, removing SIM card with no effect. I tried taking the phone apart and I can't see any problems with the power switch.
Any ideas on what is going on? I am two months out of warranty. I have ordered a USB jig since I thought it was bricked from a firmware/software issue but now I am wondering if it is actually a power button problem.
The phone is a Rogers Galaxy SIII, not rooted, running stock firmware.
Thanks.
I have the exact same problem. Only I'm on CM 11. It will let me boot into recovery and download mode but reboots after about 5 seconds in each.

If it's a stuck power button problem, this is usually indicated by the phone powering on itself once the battery inserted. In most cases, pulling out and replacing the battery would be the only way to power on/off the phone. This doesn't seem quite like what you are describing. Also, a brick is unlikely if you weren't trying to flash any firmware as you mentioned it's stock and not rooted. Sounds like a (not too serious) hardware problem which may require professional attention. If you can manage to get into recovery mode, you may try to do a hard wipe/reset.
If the s3 comes apart like the s4 open it up, take off the screws and pop the housing off. See if the button under the housing is stuck

It usually does do this. I can't see or feel that anything is physically wrong with the power button though,

I took it apart, the button looks fine, it's not stuck, seems to click normally.
Thanks for the input everyone.
Turned out to be the power button. Took it in to a repair shop, they put in a new switch and it is back to normal.
I just did a reboot of my tab and it got stuck at what I call "Black Sceen Crash".
Looks like being switched off - but isn't.
It does react on screen touches with a very brief vibration.
And it gets a litte warm.
Does not react on long pressing power button - so no reboot, no download mode, whatsoever.
Guess I have to let it run out of battery - which might take couple of days with screen off. We'll see.
Any idea what to do or what could have caused that behavior? Any similar experience?
Before trying to reboot there was no mobile connection, and I wanted to reboot to get it reconnected. Otherwise no problem.
I am running stock Samsung ROM, rooted, Skyhigh Kernel, OC/UV.

Yeah, I also discovered long pressing power button alone does not force-reset the device. I managed to reset it though by press-hold Power + Home + Either Vol Up/Down. Give that a try.
I can't remember whether it was the Vol Up or Down, try one then the other if it didn't work first time. Good luck.
After a while (30 min probably) it did not any more react on screen touches and was cold. Off maybe? Still no reaction on long pressed Power Button. Tried Volume Down+Home+Power Button - and fortunately it revived the tablet. Strange. Thanks for the hint!
I face the Black screen of death and the device (T805) was not responding to any reboot, recovery or download mode actions, sent it back to Samsung support and they claim an internal piece of HW need to be replaced, I refused that and asked for refund or new device... After a week I got a replacement device...
Until two hours ago my I747 was running fine. I picked it up and attempted to unlock it and got nothing. I decided to try to pull the battery and do a reboot, it got to the KT747 splash screen from the kernel I run and went black. I tried booting into recover and download mode. Recovery mode gives me the little blue text at the top left of the screen indicating its booting to recover, black screen and nothing. Download mode pops the warning screen and 2 seconds later, whether I press up to continue or not, it goes black screen as well. I was running a rooted version of TW 4.4.2 with the TW version of Ktoonsez most recent kernel. I have been running this combination for over a week with no issues. I tried creating a 16gb debrick sd card but the phone doesn't want to stay on long enough to boot to anything. Any suggestions would be greatly appreciated. If there is any other information I can provide, please let me know and I will add it.
****edit for more info*****
I tried having odin open on the pc while i booted into download mode. Removed battery and usb cable from the phone, inserted battery while holding vol down and home. Download mode came up, pressed up to enter and quickly inserted the USB cable. Odin detected the phone and one second later shows it was removed. I have tried multiple USB cables as well.

After several hours of cussing and google searching I came across a thread that described my issue perfectly. The solution turned out to be a stuck power button on the phone. Just like my phone, the one in the thread would boot immediately when the battery was inserted and shut off at the splash screen. Recovery and download mode both did the same, as does my phone. The site suggested rapidly tapping the power button to jar it loose. This did not work for me. Neither did the suggestion of sliding a finger nail into the gap between the chassis and power button. I went so far as to disassemble the phone and remove the physical button from the case. I put the battery back in and the phone booted immediately. The problem persists, the phone shuts off completely after a 2 - 3 seconds. This occurs with the battery in or with the battery out on USB power.
Sometimes messing around with the power button will work, but not always. Its only a temporary solution in most cases anyway.
The switch appears to have gone bad and will need to be replaced. I believe the part is only a few bucks if you want to DIY. Otherwise most local cell phone shops can do the repair relatively cheap from what ive been told.
My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.
Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks
Your welcome let me know how it goes. Will do my best to help.
I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.
How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?
To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.
Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.
Hello everyone, thank you for your time.
TL;DR: Phone boots into download mode up until "Downloading...", recovery mode until "RECOVERY BOOTING," and can only boot right when I put the battery in. The battery is fully charged, and I can boot up until my home screen only once so far. Will a jig fix the issue, or should I try to get the phone replaced by TMobile warranty as I have before?
I have a Galaxy S3 from TMobile, and have been running CyanogenMod for about a year now. 2 days ago I flashed a nightly release, which I assume was unstable. Yesterday, my screen was on and then my phone turned off (low battery, but 99% sure it was a crash rather than a power off), and did not boot up again. After attempting to pull the battery out, charge for hours, turn on and plug in (in different combinations), the furthest I could get was a couple of seconds of the CyanogenMod Galaxy S3 logo initial boot screen (not the rotating splash screen).
I took my phone to TMobile today and was about to get it replaced until I realized I didn't mask the flashes.
The last time I was in an exact same situation with the same phone model, and my flash counter was still showing custom firmware, yet I did manage to get it replaced effortlessly, but I didn't want to risk what was a possible fluke again.
I get home, and here's my current situation.
The only way the phone boots up in any manner is when I take the battery out and the charger is not plugged in. Here are the scenarios I run into:
1. Boots into download mode, can press VOL + to get to the "Downloading..." screen, then shuts off 2 seconds after.
2. Boots into recovery mode, only up until "RECOVERY BOOTING", then shuts off.
3. Boot by pressing power button, plug charger in, shows grey battery icon.
3. Boots into download mode, can press VOL -, either shuts off, OR
3b) Only after tons of tries, it booted up all the way up until my actual home screen, then shut off.
I can't have the charger plugged in while booting (pc or wall), and I can only boot right after I put the battery in.
Are there any suggestions as to what I should do? I was thinking of buying a jig from Amazon, but I don't know if it is hard bricked or not. Should I just attempt to get it replaced under warranty once again, even though it shows the flash count?
Thank you very much!
FIX: STUCK POWER BUTTON PROBLEM
So, one thing I didn't check. Take the battery out of the phone, wait about a minute. If it buzzes as if its powering on, that means that your power button (either the actual button itself or the switch on the mainboard) is stuck.
Solution: Smack the power button with your battery until your battery has a (small) dent. If it doesn't work, smack it a couple more times. Took me 2 tries, second try, phone didn't buzz when I put battery in. I press the power button, works like new. Absolutely....ridiculous
