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

ok so it got a bit wet, then started rebooting randomly once or twice (when i say a bit wet, it was some sticky kids medicine)
it stopped doing that but the power button was a bit sticky so i applied suction to get any residue out of there and the button stopped sticking.
but now its on a reboot loop.
it goes to the gt n7100 screen, then goes off then back to the n7100 screen.
ive tried going into download mode, but it gets to the "warning custom OS" screen, i press volume up and it just restarts again.
ive tried plugging it in to charge and it brings up the battery icon and a circle wait timer then after 10 seconds or so it flashes again to the wait timer (which is not turning)
what else can i do to make it work? is there not a pin button for factory reset anymore?
It got wet. So it's not a software based problem.
Return it to service center and see if they can fix it.

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.
S4 using Insane KK v9 and everything has been running smooth for a long time now but now the phone will randomly shut off when on battery (full charge). When I try to power it back up I get the samsung logo for a few seconds and then it goes blank and shuts off again. Battery pull results in the same, but if I plug it in again it might boot up normally, OR I get a grey battery pic followed by a green one showing a charge, but still unable to boot.
Any ideas?
Could be a stuck power button. Try to see if you can fix it by hitting the side against a surface or open the device
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
Phone can't boot at all, loops on plug in screeen & occasionally "charges"...
I've tried looking up a solution to this but can't find anything anywhere. I've been trying to fix it since last week.
Friday night my phone's battery ran out, yeah whatever, I'll just throw it on the charger. Plugged it in, and the screen that normally indicates you should plug your phone should come up. It's an empty battery with a lightning bolt inside of it. A few seconds later, the red "This Build is for Development Purposes Only..." stuff that comes up because of the custom ROM shows up at the bottom of the screen. After a few seconds, the screen turns off. It then repeats this from charge me icon, showing red text, then repeating. I'll be referring to this as Boltlooping.
So the first solution I found was to reset the battery logic by holding vol up/down and power for a few minutes. I rubber banded the buttons down and tried it. Nothing.
Second solution, plugging it in and immediately holding power button hoping it would boot. I tried this 5-6 times. Nothing. I've also attempted booting in to bootloader and recovery from this screen.
Occasionally, however, something that I can't identify or reproduce causes it to go to the normal charging screen. Trying to boot it from here from any battery % puts it back in to a boltloop. I've also tried doing the battery logic reset from this screen, but it doesn't work and puts it back in to bootloop. After trying to do either of these methods and getting back to the normal charging screen, the battery will be back at 1%.
This is as far as I've gotten with troubleshooting. I can get to the normal charging screen, though the battery will die and reset the charge % if unplugged or an attempt to boot is made. Most of its time, however, is spent in this boltloop state. I've tried resetting battery logic, booting in to recovery, booting in to bootloader, and booting normally from both the boltloop and charging states. Nothing. I don't know what to do.
