    Do the same thing but hit volume up instead of down. And then clear cache. If you have your data backed up you can do a factory reset

    it is a custom operating system. There are developers who take samsungs software and rewrite it the way they like it. Or they take stock Android and load it to the device with some modifications... These custom OS's are called custom ROMs by tech community

    Did it ever turn on
    And what changes have you made to the phone? Apps installed? Tried to root? Anything else?

    As a first step, try pulling the battery, wait for a few minutes, and try again.

    I am also from Canada. I had my S3 for five months. All of a sudden while I was taking a video picture, the phone shut off, tried to turn it on but kept on freezing on Samsung galaxy S3 logo. I tried the power, home and volume down buttons and got the same message. I took the phone to WIND authorized repair centre. They refused to fix it telling me that the phone is rooted which is B.S. I know for a fact that i never rooted the phone, not even updated the firmware, Just a stock with no upgrade. I am going to send it to Samsung and let them have a look.

    I would love to hear from the people who had the same issue and if they resolved this problem with Samsung warranty. Any response would be appreciated.

    If you can't boot into recovery (volume up, home, power), and the phone won't take a charge, I don't think there's much you can do other than return it for warranty service. If you know someone else with an S3 you might want to try a different battery, just in case that's the problem.

    That's a new one! Can you boot into recovery (volume UP, home and power)? Are you rooted?

    Assuming you're not rooted, and can boot into recovery, you use the volume up / down buttons to select from the menu, then the power (Or is it home? -- if one doesn't work, try the other. ) button to select the chosen option. I'd suggest trying to clear cache first, and then reboot. If that doesn't work (and I suspect it won't), then you're faced with a factory reset.

    Hi

    My S3 is stuck on the initial screen that says Samsung Galaxy S3 GT-19300. If I press the on/off button nothing happens. If I press it for a long time it the screen goes off for about a second then the same screen appears. I tried taking a battery out put it back in switched on and the same screen appears. Hard reset wont work (Volume up, power button and Home button). It turned on but it will stay frozen at the name Samsung.
    I repeated same and I pressed the volume down button, the home button and the power button at the same time to try and fix it, but it gives me a message saying "Warning: a custom OS can cause critical problems in phone and installed applications. If you want to download a custom OS, press the volume up key. Otherwise, press the volume down key to cancel."
    I pressed volume up key, It says: downloading. do not turn off target!!
    The screen is frozen even in this screen, Please help me to rectify this problem..,

    That key combination (vol down, home, power) puts the phone in download mode. The intent is that you connect it to a PC running ODIN, and can use ODIN to download a new ROM or other system files to the phone.

    What you probably want is recovery mode, which is volume up, home, power. As soon as you see the Samsung logo, release all three buttons. If you've timed it right, the phone should boot into recovery. If you release the buttons a little too early or too late, the phone will try to boot normally.

    Once you get into recovery, use the volume keys to select an option, and the home key (I think....if that doesn't do anything try the power button) to execute the selected option. You probably need to select Factory reset.

    My samsung galaxy s3 feel yesturday on the side walk, it cracked but I was still able to use it. Now today when I went to use my phone the screen is black, I tried turning it back on and it will just vibrate like the phone is still on, I turned up the volume to see if my phone is still on, and it is, but my screen is black, nothing shows up.

    I'm really sorry to hear that, ladybug. The LCD is damaged, and there's probably nothing you can do at this point but repair or replace the phone. If it's not pin or pattern locked, you can probably connect it to a PC and copy off any files you need.

    Im currently having the same problem with my s3 too. Saw that there was an update so I updated the system. Im just not sure what version it is. After downloading the update earlier, i installed it and then my phone got stuck in the samsung logo. I tried to press the power button for a long time, tried removing the batteries, the volume down+menu+power thing and still my pone opens up to the samsung logo only. Is there anything else that can be done to spare this phone?

    What version of the S3 (e.g., what carrier, or unbranded international) do you have. What update did you try to install, and what instructions did you follow (post links). It's never a good thing to manually apply an update if you don't know for sure what it is. If you're lucky, the ROM didn't actually install, and a factory reset will fix it:

    Turn the phone completely off (this won't work if you start with the phone on). Press and hold volume UP (not down)+home (not menu)+power. Hold all three until you see the Samsung logo, then let all three go immediately. If you get it timed right, the phone will boot into recovery. If you release the buttons a little too soon or too late, it will try to boot normally. Just turn the phone off and try again.

    Once you're into recovery, use the volume buttons to select Factory Reset, and the home button (or maybe it's the power button, I don't remember--if home doesn't do anything, press power) to execute it.

    If you can't get into recovery at all, or a factory reset won't help, you're going to have to try to boot into download mode, and try to load a complete, stock factory ROM. To help you we'll need to know what version of the phone you have.

    Jerex, did you turn the phone off before trying UP+Home+Power?

    If you did, then you're probably releasing the three buttons a little too early or a little too late, or not pressing them all at the same time. Start with the phone off, press and hold all three buttons together (you can't press one first, then the others), and as soon as the word Samsung appears let go of all three buttons.
