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.
****edit for still more info****
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.

Hi i have a telus T989D, stock unrooted. I was trying to open a picture in my gallery and my phone restarted, then it showed the samsung loading screen and at about 75% it restarted again. Then it just vibrated, paused, vibrated, paused, etc. and its a blank screen. I tried holding volume down + power and it takes me into download mode warning screen, but it shuts itself off before i can do anything and continues this blank screen vibrating loop. ive tried pulling the battery, but the second i put it back in it loads the samsung screen, restarts and continues the loop. if i cant even get it to stay in download mode is it even possible to fix this?
sounds to me like you have a sticky power button (very common) on these phones/samsung !!! so if wiggling a took pick in there and un jamming it a bit then you need to send it in try leaving your battery out for like 10 min take out sim cards memory everything leave it sitting ..... then try again
There are some fixes for the sticky power button here:

Read the whole thread and then try some of the easier fixes first.
try getting into recovery mode and wipe data/factory reset
you guys were right about the power button. opened it up and pried a bit then it worked again
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.
Okay I will try to sum this up. My S3 was working fine and everything randomly I noticed issues with battery calibration It would be 100% then I would calibrate it and then unplug and then I'd instantly drop to 85%. Thought It was a battery issue and made a point to get a new one later. Then it kept working for another month or so then It started really screwing up the shutdown menu would randomly pop up and I'd back out of it.
Then randomly 3 seconds later the phone reboots. And it would keep doing that randomly I thought it might be a power button issue. Then as time goes on it got really bad to where it would simply reboot and not make it past the bootloader, It would not "reboot" more like a complete shutdown then I'd have to power it again and have it do the same thing. Seeing how I could not even make it past the bootloader I got a new battery, waited a week for it and then I put it in and the same issue happened. It would not get past the bootloader.
So I kept trying and trying and trying and it finally booted past that. And it stayed on for a whole night. I did everything on it I normally would and it was working great. Then the battery was getting low so I plug it in and was going to calibrate it after it was charged, I go back to it and it's dead again won't get past the bootloader once again. I'm completely out of ideas on how to fix this I pop'd off the button and blew in there and the button seems fine and everything still no change. I also can not get into recovery. It trys and loads but then shuts off. Anyway if anyone has any ideas on what this is or how to fix please help! I need my phone back! Thank you.
I'm running MOAR Lite version.
UPDATE: Took the phone apart and took a close look at the button it looks 100% fine...I saw a video on youtube that requires you to complete tear the button off and it works. But I don't know if the button is my main cause of this issue or if it will actually work. Some says it works, some says it does nothing...Please let me know thanks...
UPDATE 2: It will show that battery with spinning circle in it for like 1 second then turn off again. (When it is plugged in)
That's odd. But when it comes to the power button, dismantling and what not 90% of the time will show 0 issues. It will look perfectly fine when it's not. You playing with the power button I assume were pressing hard and normally to try testing it. It's a common issues on this version of the S3 to have faulty power button and you would need to get it repaired. Odly even slightly atmospheric changes can cause it to act different at different points. Some days it works fine, other days a very slight brushing over can cause it to screw up and trigger a manual shut down (holding for like 10 or 15 seconds).
Assuming that it is the power button, or to try, just do a variation of things to the power button itself. Use your finger nail to jiggle it around with different pressures. During boot if it shuts off, it could be the power button internally stuck, just jiggle it around.
This is all I can think of unless you bring it in to get repaired.
I was encountering the exact same problem. I would try to get into download mode and it would sit at the "Downloading" screen for about 5-7 seconds then the display would go blank. It won't make it into recovery either. Based on the above recommendation I took the whole phone apart and sprayed a lot of compressed air directly on the power button mechanism and the plastic case pressing the button in. I didn't see anything broken with the button when I did that.
It seems to be working now, I can boot into my Rom. Don't know how long this fix will last.
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
Last Saturday night my Verizon S8+ suddenly began to freeze. It would do it with many different applications so I don't feel it is associated with one in particular. It then would restart and would hang at the Samsung splash screen. I was able to boot into maintenance mode and then select safe mode. It would boot to safe mode and would function as expected but then without warning restart again. I took the phone in to a local repair shop who said it could be the battery. Replaced the battery and it seemed to work but then started the boot loop again. Since the battery didn't fix the issue I did get a refund. At any rate after letting the phone sit on the wireless charger overnight it did appear to have fully charged and I was able to boot it up normally. There are some pictures that I needed to get off the phone so I plugged it in to my PC and started copying files over. After about 3 minutes it restarted on it's own and the whole boot loop process again. Now be aware that I know just enough about what I'm doing to be dangerous so here is what transpired next. I started pushing a combination of the power button, the bixby button and the volume up and down buttons and managed to get into the downloading a custom OS menu (see attachment 1) I didn't feel comfortable with this so the screen clearly said if you want to download a custom OS press the volume up key otherwise press the volume down key to cancel. Well I must have fat thumbed the volume down key and by accident pressed the volume up key. Upon rebooting it tried to perform a software update but would give an error message file not found. After several attempts to bypass this screen with a combination of pushing the buttons I was able to boot the phone into recovery mode (see attachment 2) and that is where it is right now. Good news is it hasn't tried to reboot so obviously it in a boot area ahead of whatever was causing the issue to begin with. I also note that the blue charge light indicator seems to be glowing from dim to bright as if I am charging the phone but I don't have the cable connected. So that's my story and I'm sticking to it. I am hopeful that one of you Android technical gurus could advise me of a way to recover the functionality of my phone through this menu? I have attached a couple of screen shots relevant to my issue. Please help and thank you in advance for any assistance.
