I recently got my wife an Excalibur (I've been cooking/flashing Kaiser Roms for a while) and unlocked/upgraded it without issue.
She's been using the phone several weeks, until the following series of symptoms began:
1. Phone shuts down several seconds after booting up - sometimes with shutdown screen/noise, sometimes without.
2. Phone will not boot up again until battery is removed and reinserted, at which point it automatically boots (without depressing power button).
3. Phone shows full battery and charging light indicates charging while on, but will not appear again after shut down.
4. Phone will NOT hard reset using soft-keys + power, or enter bootloader using camera button, and thus cannot be hard-reset or re-flashed.
The only (non-ruining) possibility I can think of, which I'll look into, is mis-sensing the power button permanently depressed (which may initiate shut down after boot-up and prevent bootloader/hard reset?).
That, or some bizarre hardware/power issue.
Any ideas?
Thanks for any help...
I'd buy "borrow if can" a branded battery like simplo and see if you have a battery issue?
Also worth considering is the charger what happens when plug in via USB?

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.
Hi everyone,
As the title says, my phone simply will not boot past the samsung logo. I insert the battery, a few seconds later there is a vibration. Then the samsung logo appears, and it shuts down. It does not reboot itself; it just suddenly dies. After it the shutdown, all buttons are unresponsive; holding the power button will do nothing.
I have tried plugging in the charger both with and without the battery inside the phone. When I plug in the charger, the red LED that indicates that it is charging turns on. After a few seconds it vibrates, then almost immediately the red LED light flickers off, and everything is just as unresponsive as before. Leaving the charger inside will yield no results or change.
I have tried to turn my phone on with the battery and charger plug into the phone with a few variations. First, charger first, then battery. The battery is inserted within a second or two of plugging in the charger. The red LED light appears, then the light turns off right before the vibration. The screen shows the battery logo that indicates the phone is charging. This image appears for a few seconds, then it becomes unresponsive as before. Second, battery first, then charger. There are two more variations for this. One is battery, then plugging in the charger right after the battery is put in (before the vibration is felt). After the vibration, the battery logo appears for a few seconds before it shuts down and becomes unresponsive again. The second variation is: battery first, then vibration, then right after the charger. Same result as before.
I have also tried to remove both sim card and sd card. No avail.
I have tried to boot it into recovery mode, as well as download mode. Nevertheless, the phone will shut down before getting into any menus.
I have tried to tap the power button multiple times in case the power button and home button were stuck or jammed. However, I doubt this is the problem.
My computer will not recognize my phone, since I cannot boot it past the samsung logo.
I have tried using different batteries, same issue.
I am aware that a factory reset may be an option that I may have to take, but I have some important data on my phone that is not backed up, and I would very much prefer not to lose it all. I would appreciate any insight on how to fix my problem.
Thanks!
Mine was doing this for a bit until I realized my power button was stuck. The button seemed to press fine and all and looked fine physically, but the contact was somehow stuck. Take apart the phone, direct some compressed air into it using the little 'straw' for the nozzle to focus it... Also try pressing the button a bunch of times hard, etc. And see if that helps.

Fixed it! Opened it up, jiggled around with the power button stuff. I had no idea what I was doing. I blew, with my mouth, really hard on it. Now it works. laaaaaaaaaaaaaaaaaaaaawwwwwwwwwll
You helped! Thankyou
Now would be a good time to backup that important data. A lot of the time, that's is just a temporary fix and it may happen again.

Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.
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
If you are facing similar problems like me, see Help! bootloop per 5 sec, cannot enter rec, download or fastboot, and don't want a burn-in screen, try a physical method to shut down your phone: low temperature.
Put your phone into a refrigerator working at around -20℃ (maybe -10℃ is sufficient, but not tested) for about half an hour (depending on the current temperature you're in, but not much difference), or if it's cold enough outdoors, you can put it outside as well. Then it should be shut down due to the battery protection mechanism.
Caution, do not drop the temperature any more than that mentioned above, or you would damage the battery permanently (I'm informed it's less than -40℃).
PS: one more way to turn off the screen (not real shutdown) if you have a working computer: entering 9008 mode. Connect your phone to the computer via USB. Hold volume- and power button, press volume+ for multiple times. If the screen is not getting black, unplug the cable and try it again.
Update: @runningnak3d mentioned in https://forum.xda-developers.com/showpost.php?p=80216986&postcount=7 that hold all the three of vol+, vol- and power keys for countdown reboot and at the second time release them, then the phone could be turned off. But I cannot test it now and I doubt if that works at any time. If you succeed please reply to let me know.
