[Q] SGS3 Won't Boot [But Vibrates]

It's weird...whenever I try to do any of those things, the screen will turn on for a moment [the backlight, no logo or anything comes up] and then after about a second immediately turns off....I tried injecting a rooted version of the stock rom with Odin into my phone, but I kept getting strange error messages like TouchWiz isn't working and some other android process isn't working.
[That didn't work, so I decided to try a different method. This is where I ****ed up, because I forgot to go back to stock rom...]
Anyways, after that, I tried to use the SGS3 Toolkit [if you search sgs3 toolkit xda, it'll come up] and I tried to use that to root. I went to "rooting options" and i selected option number 3, the all in one. I got to the point where it mentions your phone must be in USB debugging, and now nothing comes up when I try to start the phone..but it vibrates whenever I hold the power button long enough [as if it was working normally]. I can't get into download mode right now, either...
How do I reverse this and go back to stock? Please help...thank you so much.
EDIT: It's weird...whenever I try to do any of those things, the screen will turn on for a moment [the backlight, no logo or anything comes up] and then after about a second immediately turns off....

I'm basing this answer based on how I understood what you said...
But, if you're already rooted, then hopefully you've made a backup before installing another ROM. If you have a backup, then put into recovery and backup.

I wasn't already rooted, I was trying to root it. I can't get into recovery.

Can you get into download mode? By holding Volume up, home up and power.

Was your phone plugged in when you tried get get into download mode? if so, try unplugging it and give it another shot. the s3 can be kind of funkysometimes.

Same thing, no dice :[

Plug it into the computer and see if anything shows in device manager.
I hate to say though, I think you may be bricked....
Unless anyone else can think of something to try?
Sorry man...

Also you can try safe mode. Doubt it'll work but I just learned how to do it so thought id suggest. Hold volume down + power.

Have you plugged into the computer and checked device manager yet? What does it say?
I think if it says something like qhsusb that means its bricked.
I'm hoping someone can verify that though since I'm going by memory.

Well, I sent it back to T-Mobile and said hey it doesn't work. Let's see if they say anything about it. They sent me a new one, though

I'm having exactly the same problem with my T-Mobile Galaxy SII T989 running Open Kang AOKP JB Jelly Bean. After reading this thread, and another related thread (http://forum.xda-developers.com/showthread.php?t=1679492), my less than scientific observation is that pressing/massaging/jiggling the power button seems to bring the device back to life. At least until it flakes out again. The posts in this thread were a big help. I was going to ditch the ROM, which would have been a shame. Thanks.

[Q] Cm10.1 stuck in Vibration Loop

I installed CM10.1 yesterday on my T989. I updated it this morning with the newer version of CM10.1. So today I was at work, I was listening to some music and in the process of sending a text, my phone shuts off. I attempted to turn it on, it said "Samsung," and goes into a vibration loop, nothing loads. Then I tried to go into Odin and go into download mode, and it shows the download mode screen, then shuts off. I am running out of ideas. Hopefully you guys can help, Thank you!

[Q] xperia s dead

I've got a dead xperia s, I only have the red led as mentionned in a few other threads.
Nothing is happening when i press the power + volume up or down keys.
I've been trying the sus tool as mentioned with rubber band trick for a few hours but without result.
the red light stays on, after a while it disappears (no led at all) and returns.
Is there anything else I can try.
I've also read I must discharge the battery, but how can I discharge it without turning the phone on ?
One time I did get the green led, but it failed beceause no driver was found.

How did this happen? What have you done before hand?

maybe now your xperia s is discharged

doesn't it charge when connected with pc ?

not in fastboot mode, and if you connect your xperia s normally and nothing appears, you need to charge your battery outside of xperia s

Remove battery, put charger, put battery back. And yes, you will void your warranty.

what good would do the charger after removing the battery ?

It will give the battery a voltage shock.

How can it give a voltage chock when I first need to remove the battery ?

I have also read the disconnecting the flex cable from the mainboard could be a solution, does it need to be the flex cable or is removing the battery enough ?

Remove it. Put it back in. Start charging it and then the voltage tweak is going to happen. But removing the battery it's not easy, I do not recommend to do it,maybe at an authorized center.

Rooted Phone won't boot, can't access recovery or download mode.

Hello,
Today my phone randomly turned off by itself, and when I turned it back on, it got to the samsung screen and then went black. After I tried again/pulled the battery, it did the same thing. I can access recovery and download modes, but when I tried to restore my phone, my phone ****s off before the process can commence. Since the phone barely stays on for 5 seconds, I can't get Odin to see my phone. Please help. My phone is rooted, but I never installed a custom ROM. I'm still stock.

Try to pull the battery, then plug in the USB. You should be able to enter download mode without the restart.

Doesn't work. When I plug it in without the battery, the charging light comes on, then turns off, then the mini vibration happens. But I never get a samsung screen. Can't access download mode at all without the battery.

That did happen to me before. I'm trying to remember how I repaired it. When the battery is in, and turned on. Is it rebooting alot or stuck on the Samsung screen?

The samsung screen will come up, disappear, and then the phone doesn't do anything again. I have to pull the battery to get it to turn on again.

Not before this happened...

Hmm. I'm stumped. Sorry. I had the very same issue with my i777. I had the Odin screen on while I fiddled wth the USB connection at the phone until it finally stayed connected long enough to push a recovery to it. Although it doesn't appear you have the same issue. I figured I'd throw it out there. Again. I'm sorry I can't help further.

Not to my knowledge, I can still push it just fine.

There have been more than a few instances where someone would have similar issues where if would shut off after a few seconds. Most times it would reboot itself over and over, but for a few people it would just shut down.
Most of the cases I've seen, it turned out to be something keeping the button in contact causing it to trigger the switch.
Sometimes it was the button itself got jammed, others the button felt ok, maybe a bit loose, but under it it was essentially pushed in. A couple have apparently just had a bad switch or a short.
May or may not be the case here, but thought I'd go ahead and mention it.

Some people simply opened up the phone and reseated the button. Others had to buy a new button and replace themselves. Some sent it in to a repair shop to have it done for them and a couple who suspected it was an issue with a switch or a short on the board I don't think were ever able to fix it.
One guy got mad at his and slammed it on the table. After that he said it worked fine! I do NOT recommend this!!! But I have fixed stereos, VCR's, CD players, and all sorts of electronic equipment with this method! I would never attempt it with this fragile screen though!

What I recommend is that you go to a phone service centre that does JTAG, that way they can diagnose and repair the motherboard

I can't be so sure, but to me it sounds like the motherboard, if you have used triangle away before and have a clean flash counter you could send your device to Samsung for service and repair?

I was under the impression that Sudden Death couldn't happen to US variants and they they had fixed it in the updates, guess I was wrong. Gonna have my friend look at it, if he can't fix it i'll send it to T-Mobile.

when you try to access dl mode you get the option to continue or reboot, choose reboot and long press home and volume up, this will cause recovery to boot up (I sometimes have trouble getting it to boot with my problem without this method) then flash your rom again or flash a firmware package. this will at least get you into your rom for the time being. Then you can work from there.

did you try taking battery out for about a minute then putting back in and trying to boot to recovery?

Phone died - Very peculiar case

So last night I went to check my phone and it was off so I figured it had gone off on its own but upon trying to turn it on again I found that nothing was working. I plugged it in and got no response. Took out the battery, tried to boot to download mode, or reboot and have tried just about everything to be found online. I left it plugged in all night and nothing. I called samsung and their suggestion was to hold the power button pressed down for a few seconds so after that extremely well thought out suggestion didn't work they said that I'll have to take it in on monday as their service places here are closed during the weekends.
my problem is that I haven't backed up my info and I can't afford to lose it and they said that they will wipe it once they get their hands on it. I don't have a second battery to test but I just plugged it into my computer and it was recognized as a USB device. Nothing more, not what it is and doesn't show up anywhere and nothing has happened on the phone but at least it was recognized.
This is the most messed up issue I have every encountered and it happened entirely on its own. Im all stock and am running purely simple apps like viber and whatsapp and seriesguide and family guy. Its the most mild mannered phone and has the most messed up issue. Its like someone sucked the electricity from it. Please give me some ideas
