Hey all, I have a S3 i747 on rogers. I have had it for a couple years everything working fine and great, I rooted it after I bought it and it worked no problem. A week or two ago it suddenly shut itself off while I was using it. I didn't think much of it, then later that day again it turned itself off.
This time, it automatically tries to reboot but as soon as the logo appears it instantly turns itself back off again. It's not that it gets to a certain point, it's like there's a time limit on how far it can progress through the boot sequence, I estimate about 4-5 seconds. No matter what I try I cannot get it past this cut off time.
I have tried download mode, recovery mode, battery tricks (found on obscure sites), etc etc etc and still its stuck in this death loop. Im fine with buying a new phone, but I had not made a contact back-up for 6 months (no, I wasn't syncing with google) and have lost many, many new contacts as well as certain files and pictures that I wouldn't mind getting back.
Also, if I am very fast I can get the first page of recovery mode to pop up, but then the "time limit" hits and before any selections on the menu can be made it automatically reboots. If I leave the battery in, it will try every few minutes to boot repeatedly until the battery is completely zapped.

Does it still keep rebooting even in download mode? If not then try reflashing your stock rom.
Or maybe try booting up without an sd and without a sim card.

Also make sure to not hold the volume and home keys too long when going into download mode, once the phone vibrates you should be able to let go. I made the same mistake on my phone and then noticed i had been pressing the volume and power keys while download mode was starting, causing it to select cancel. If not though you are probably looking at some sort of internal hardware issue that may be causing the reset to trip or causing the phone to believe it should be shutting itself off at that moment. This is all purely speculation, but hope it helps.

I can't even make it into download mode, or recovery mode. Like I said, its as if the phone has a built in time-limit for how long it is going to load, the absolute farthest I can get is the first page of recovery mode and then boom it instantly resets before I can even make one selection, and I did this like 100 times in a row so I got very fast at getting into recovery mode. As per 2nd quote, yes I am releasing the buttons as I am supposed to to get into the appropriate mode, but the "time limit" hits and just reboots no matter what.
I've tried booting up without sim and sd card, but it still doesn't make it any further.

I would put my money on a bad power switch/button.

Yes, it acts like a stuck power button, a common problem with galaxy s phones.
If it auto starts when you insert the battery, that's a sure sign the power on circuit is active.
When my Captivate did this, I opened the back & carefully tapped it on a table edge to try dislodging any debris.
I then followed teardown instructions, inspected the switch assembly & blew it out with forced air.
The problem ended & never returned. I honestly don't think there was a physical defect in my phone's switch; more likely a residual charge on the mainboard.
Root causes vary as do solutions for the problem. Inexpensive switch replacement is a good one too.
Since then I have used a couple of apps to reduce the need for the gs3 power button.

Okay so ive been running jmt v8 for about a week on my phone and everything was running great. Then yesterday morning my phone became very slow and unusable. Then i started getting the error message acore system has stopped working and the phone would randomly restart and then it would start vibrating then stop then vibrate again and so on. So i insalled a new rom and i stopped getting the core system has stopped error but i am still getting the random reboots. And the screen also wakes up by itself. Please any help or suggestions would be greatly appreciated.

I just had this fixed. There's something wrong with the power sensor, especially if it tries to boot the second you put the battery in without touching the power button.
Unfortunately you've been rooted now and because of the issues, you can't flash stock and reset the root count. So you can't sent to your carrier.
Fortunately, http://www.mobiletechvideos.com fixes EXACTLY this for $35 minus shipping it to them. I got my phone back today and it's just the way it was ROM wise and all my files are there and the issue is fixed.
This is a pretty common T989 issue.

For anyone with key issues and need to get into recovery or download mode there are adb commands that do this. We get too comfortable with apps and forget about the manual way of achieving a lot of the same tasks that apps provide for us.
From a command prompt:
adb reboot recovery
adb reboot download

hey guys. after the ics update my phone started to lock up and its not rooted. now all of a sudden when i put the battery in it it vibrates once then starts to load and gets about half way and stops. then it turns off and just vibrates a few seconds and vibrates but the screen never shows anything. tryed using just a usb with the battery out and it skips the load screen and automatically starts vibrate looping. the power button seems stuck but i dont think i can fix it any ideas?
Hey everyone! I have a similar (but not quite the same) problem. Every now and then my phone "tells" me to restart it for maximum performance. Every time I restart or just turn on my phone it goes through the boot cycle, including a message that says "android is upgrading" (I got the ICS upgrade from Kies prior to rooting my phone). Then, all of a sudden, the phone doesn't work, and it starts the boot cycle all over again. This happens several times in a row, which for me is a safety issue because I'm not able to call Big Jon (my husband) to get me from the train late at night. Any fixes for that? Thanks.

Damn! Just found this thread...sounds like what my phone started doing today!!
I was clicking around on gmail, then back to home screen, the camera FLASHED all by itself without me doing anything, then started the boot loop thing. Clicking the power button only made it worse. Finally was able to get into recovery via TWRP...but that was weird too. I did a factory reset/wipe and was going to reinstall The Sith ROM that I was running, but it just rebooted and loaded up The Sith anyway and it should have been cleared. I then tried to restore back to Beastmade ROM, restore was very quick and said successful but it booted back to Sith.
Now the power button is hyper sensitive! All I have to do is brush the power button and it will light up the screen. Touch it too long and it will bring up the boot menu. I'm afraid to actually CLICK the button as it might go haywire again.
WTF is going on!? This all seems really odd that it's going down with some of these new ROMs being released. I wasn't even touching the power button when all this started. The weird clicks and flashes didn't sound good when it was all going on.
Has anyone tried flashing back to and OLD rom to see if it will fix it?
change settings to interactive/deadline
So i've looked around and no one that i've seen has the same exact problem as i do. Here's my post in another forums about my problem.
Here's my story about my Galaxy s2 for T-mobile. My phone randomly turned off 2 days and whenever i tried to turn it on, it would restart and basically never get pass the blue loading bar screen. Second, i found out about this boot loop sequence and i was able to do a factory wipe.
After i factory wiped the data etc off the phone, i was able to use it until it ran out of battery, but then after i found out it ran out of battery, it wouldn't let me turn it back on, it wouldn't get pass the loading screen, once again. On the other hand, i am able to go to recovery mode or download mode, but the phone shuts off before i can even try and click on the options i want.
Today, i found out that if i kept pressing power button consecutively on the phone, I'd be able to go to my home screen and basically act as if nothing ever happened, it'd function as a new phone! I then had the nerves of turning off my phone just to make sure it finally works now, but my hopes were crushed and now the pressing the power trick does not even work anymore. It would probably work one out of 10-15 times, and in the end it'd still restart. I am using a gingerbread galaxy s2. My friend tried using the usb jib on my phone, and it worked but whenever he tried to plug in the usb, the phone would just restart. I am extremely frustrated with this, and if you can help, please do so because it's important that i fix this phone. If you have any questions, please feel free to ask!
Hi there, thank you for the welcoming me to the forums. No, my phone is not rooted, it has always been gingerbread etc i never tried rooting because i never knew how:/ I believe this started when i was just browsing around facebook, so i'm not entirely sure what happened... Uhmm i tried going to download mode through the volume keys and power button when it's connected to usb to the i think it's odin3? and it'd be in the download mode but as soon as the computer says it's connected, the phone would just turn off again and bam, it's like nothing ever happened. My phone does charge when it's plugged in, but it doesn't show it's being charged but i remember my battery was dead last night and i charged it till today and now it's got power. ANd no i don't have a warranty:/ i really hope you can help me
Sounds like a faulty power button. Check out Mobiletech video for thier power button repair service.

I have a SPH L710 galaxy s3 (sprint). I recently flashed a Rom called hyperdrive 4.1.2 that was on it's RLS11. following the instructions (factory reset x2, wipe cache, wipe dalvik, wipe system), I then picked the features i wanted in the built in aroma installer and let the rom flash. When it was done I noticed i kept getting the message "the process com.android.phone has stopped". So i performed a clean install of my previous Rom which was Liquid Smooth.
A day or two later I noticed hyperdrive has released it's RLS 12, so i decided to give it another try. This time there was an option in the aroma installer for developer picks so i selected that, thinking my previous attempt i may have picked conflicting files in the aroma installer. The Rom worked fine for about a day. Then the next day while it was charging after the battery have completely died the night before. I noticed the phone had rebooted on its own, then it started going into a boot loop. I did a battery pull, and i noticed when i put it back in, before i could even hold the buttons to get it into recovery mode or download mode, the phone would vibrate and turn on by itself, without me pressing any buttons at all. After some trying i was able to have the buttons held so when i inserted the battery, i was already holding the buttons to try to get to recovery. When I did this it would say it was about to go into recovery, then the screen would go black. The same thing when I tried getting it into download mode, It would show the download mode screen, then go to a black screen. I Then did some research, after seeing no one else really having this problem, and noticing that since it was still seeing boot screens before the black screen, it shouldn't be a hard brick.
I decided to order a USB jig for my phone that came today. When inserted the battery with the usb jig the phone still turned on by itself, but it was able to go to download mode and it stayed at the screen. I used odin 3.07 to flash SPH-L710_MD4_1130792_Rooted_Nodata, which was a tar file you would use if you wanted to keep your user data. It took 10 minutes to flash but everything seemed to be a success, it rebooted my phone and everything seemed to be working fine. After about 20 minutes of my phone being plugged back into a charger and i was halfway through with downloading an app from the android market where out of nowhere my phone temporarily froze and then rebooted, to where it will show the samsung screen, then the samsung galaxy s3 screen, then just goes to a black screen. Now even with the USB jig, it will still power on by itself as soon as a place in the battery, go directly to download mode, but then go to a black screen within 3-4 seconds before i can do anything.
Has anyone ever encountered anything like this before? At first i thought it might be a stuck power button, but when I was able to flash through download mode with the USB jig that first time it makes me think it is bricked. Any help or insight would be GREATLY appreciated.

How long did you let it set on the black screen because it takes a while to boot up the first time after flashing a ROM.

Well i just placed the battery back in, it started on it's own without my pressing anything again, and i've been timing the last 5 minutes. but it seems like it will stay a black screen indefinitely. unless i remove the back of the phone, or snap it back into place, or any kind of micro impact movements it seems, when I do that it vibrates like it's first being turned on, and shows the samsung screen, then the samsung galaxy s3 screen, then it will go black again.
See if your adb on your computer can recognize the phone while it's stuck on the black screen. You might be able to push a Rom or recovery over using that.

You may want to just start fresh and lose your data with a different stock file. That kinda happened to me before on the gs2 and I found better results with a 100% fresh start. The no data always left me with a hangup or two after getting the phone to boot.

After the first odin flash i was thinking the same thing. But that's the thing, it won't stay on the download mode screen long enough for me to even try to flash anything else through odin. I'm also noticing when connected to the charger, if i make a slight impact against the phone with my palm, the screen will briefly show the battery icon as if the phone is charging when it is turned off, then the screen will go black again. When it is unplugged, is when it will show the samsung screen, then the samsung galaxy s3 screen, then go black again.
That's weird...sounds like something is loose. Any kind of recent impact damage to the phone? Dropping it, throwing it at your cat, anything like that?
To me it sounds like maybe your power button is stuck "down"
If you didn't know, the power button has a fail safe reboot that happens after holding for about 10 seconds. So no matter what, if you phone is frozen or whatever, holding power more than 10s will cause it to reboot. That would also explain why its turning itself on as soon as you pop in the battery.

not recently, and if it was ever dropped, it would be in it's case... But i had noticed that while it was in it's power glove case, sometimes i would have to use more than normal pressure on the power button to get the phone to respond. I was wondering if something was stuck, just haven't read anything like that happening to anyone, and when I used the jig the first time the screen stayed on.
I run a M.O.A.R. stock 4.2 rom on my Sprint GS3 SPH-L710 (that is out of warranty). Yesterday, I was scrolling through facebook when my phone spontaneously rebooted. It didn't lag, or slow, or start to not respond. I was scrolling through my feed, and suddenly it was going through the boot screens. Except it wasn't just a reboot, it went into a boot loop.
I let it reboot maybe four or five times before pulling the battery. After a few minutes, I started it up again and it was fine. It operated normally for the next couple of hours until I felt it vibrate in my pocket, and when I pulled it out I found it had went into a boot loop again. Once again, I pulled the battery.
But this time, the phone wouldn't power up. I couldn't get it to power up, go into recovery mode, download, anything. Every button combination I tried produced no response. I tried using a different battery, didn't work. I tried charging my phone for a few hours (even though my phone was >75% when this happened) and even the battery indicator screen didn't show when I pressed the home button.
I searched for possible fixes, but I couldn't find any post or thread that was similar enough to the situation I'm in. I'm 99% sure it's not Sudden Death Syndrome, and that's about all I've found.
Anyway, I need help. What can I do (if anything) to make my phone work again?

It was my understanding about SDS (and please, by all means correct me if I'm wrong) that a) it only affected phones with firmware below 4.1.2 (and that 4.1.2 and 4.2 had a patch to fix SDS) and b) and it only affected international models, i.e. i9300.
One beautiful day the phone just restarted from itself. (wasnt really shocked though) After that it entered again into a boot loop, Im saying again because it happened once before and i noticed it was the SD Card and I just had to format it. So far so good, but now it doesnt matter if I pull out the SD Card or SIM, even battery... once ive put the battery the phone starts booting from it self and restarts everytime on a different place, like samsung logo, CM logo, CWM recovery, download mode.. it just cant stay on one place so i can choose an option. Only once ive managed to do a cache and dalvik wipe, also didnt help. Keeps rebooting and rebooting. Ive tried different ways of booting, with USB cable, with the recharger adaptor and without them. Left it for a whole night without battery, didnt help. I cant even manage to flash the stock ROM again, still reboots. I thought the power button was stuck or something, tried moving it arround but also didnt help. If you ask how many time Ive flashed the device... well perhaps countless, about 40 times counting the stock firmware. (maybe this number for some other maniacs is little, but now i see it like too much, because im kinda attached to this phone, the previous HD2 suffered a lot more xD) So guys my question is, do you have any suggestions? Ive searched the internet to check if the symptoms are close to hard brick but... didnt really saw any identity.
So.....
Normal boot.....it reboots, shuts off reboots.......?
Recovery mode.....reboots, shuts off, reboots.......?
Download mode.....reboots, shuts off, reboots......?
Battery insertion.....reboots, shuts off, reboots.......?
Same sequence every time?
Irrespective of which of the above scenarios is taking place?
If you just sat and watched it without pressing any buttons, will it endlessly reboot, shut off, reboot?.....
During this cycle, does it get to the same point in the boot process before restarting?.....

Thank you! I thought nobody will answer. It reboots right after passing 3 to 5 seconds, sometimes on the CM Samsung splash, sometimes on the spinning CM circle(boot loading image), when i succeed entering CWM or download mode reboots again. I cant boot it normally and reach the home screen. I read something that it could be from the kernel boot code, im using CM 10 (if im not guessing wrong).
I've answered a number of threads in the XDA W forum where members were experiencing similar issues to yourself. I doubt it's software related as during access to download mode and recovery mode , the phone isn't even using the "main" system software and kernel....these modes use their own independent kernel and system (it would be HIGHLY unlikely that two separate systems and two separate kernels are suffering from the same fault).
If all of the symptoms I wrote about in my original reply apply to your phone, then it all points towards a faulty power button.
As I understand it, Samsung uses a type of button commonly referred to as "temporary push to make" which means that when you push the button, two contacts are bridged to make an electrical connection but when you release the button the contact is broken. Under normal circumstances, this "make, break" sequence will start a normal boot sequence. Under normal conditions, long pressing this button again will begin the shutdown process. Now assume for a moment that the button has become damaged....where this contact that is meant to be momentary, has in fact become permanent......the result would be a phone that will attempt to start up and shut down in an endless cycle....basically, YOUR phone........

Yeah, I also thought that as a reason but discarded it quickly because the button doesnt have any problems when pushing it. I mean it freely comes back when pushed and i can also freely push it without problems. Also discarded that problem because i thought the button cant stop the booting cycle while booting, but it seems like it can. Thanks for all the answering I will try fixing it and will report as soon as possible.
The plastic button is separate to the electrical part I described....so it is entirely possible for the part you normally touch to *seem* to be working as it should.....only for it to work against the faulty electrical part........
And yes, that type of fault IS caused by the permanent contact of a faulty electrical button. Anybody who has a normally booting W (as I do) can re create this fault simply by pressing and holding the power button......the phone WILL enter a boot/shut down/reboot cycle for as long as the button is held........
The same condition can be re created on my S2 in exactly the same way as well.....

Well.. bad news.. i've managed to disassemble it, tried to see whats wrong with the button (not the plastic one), tried moving it arround, nothing seems to be damaged, still stable at one place, also tried booting the phone 3 times without any covers and the result was the same...
Perhaps i should drive it to service.
Check your date of purchase.....Samsung phones have a two year warranty.......

Well bad luck here also, i got it almost brand new from England and I'm not from England. I bought it over online shop sold as a second hand long time ago, it was just a matter of time to damage him. Thanks anyway for all the help, I'll see what i can do with the service.
Bad luck mate.....word of caution though.....as you've found out, the button is soldered directly to the motherboard, Samsung's "modus operandi" seems to be rather than attempt to repair the button, simply replace the entire MB........for a phone that is outside warranty, this will have (erm) "cost implications" lol......basically they like to charge as much as they can in situations like these.....eg/ board replacement when button repair would be enough.....

True, my phone suffered the Power Off Loop as you may know from my previous thread. I decided to send my phone to a couple of repair shops and they said that the phone "cnt be repaired". i thought they knew about the change of MB but no. So rite now, my Galaxy W is in the grave ...

i had encountered this issue with my galaxy wonder today and would like to seek for solutions over the internet. regardless that i also checked the button by disassembling the covers and separated the plastic button with the one on the board and tried to boot it but it still the same.
as most of you guys experienced this issue, what would you guys suggest me to do with my phone? i wish to save this phone for sentimental reason. would change the button DIY-ly is worth it? is it available for me to get the parts?
or did you guys manage to get a better solution?
thanks!
