It was also bricked from  rooting process because you installed with a wrong root kernel images. Those are just the most common issues why the heck you screwed up and bricked your Samsung Galaxy S3 phone in a wrong place and in and wrong no time.

Symptoms of bricked Samsung Galaxy S3 (AT&T SGH-I747)

Here’s a couple issues you might be facing by now and wonder how to resolved.
1. The phone boot and shows the Samsung screen for a split second and then it automatically turns off.

Somewhere stuck on these following boot screen.
1st boot screen: ‘Samsung’
2nd boot screen: ‘Samsung Galaxy S III’
3rd boot screen: AT&T splash screen
4th boot screen: pulsating ‘Samsung’

2.  It won’t  Power ON but it just shows the odin download screen with yellow triangle and firmware update warning.
3. The phone keeps on restarting (with vibrations) after the Samsung logo appears.
4. The phone is totally dead, unresponsive or no visible signs of life.

Does a bricked Samsung Galaxy S3 (AT&T SGH-I747) can be fix or recover back to normal?
Yes and NO, there are two types of bricks – the softbrick and hardbrick.
The Softbrick – can be recovered if you can still access your Galaxy S3 Download Mode screen -  (Pressing VOLUME Down + HOME + POWER button). Try to press that button combination. If you can access the download mode option, then your seemingly quite lucky for  there’s a chance that you can recover it by yourself.

Hardbricks – refers to the phone as totally jammed, it doesn’t show anything, can’t access the download mode screen. The only solution for this is by called JTAG flashing, which is forcing to install the firmware back to the phone. The process is not too easy, this includes disassembling the phone, some soldering required and flashing by means of using a flashing device tool. So this method means that you cannot save your device all by yourself anymore. If you badly need  to have your Galaxy S3 back to life if you can’t recover it anymore with yourself is to bring it back to your dealer. Explain something  that might encourage them to have your phone fix for free or have an exchange for warranty.

Hey dude I can still access the download mode!
Great! If you can still access the phone into download mode, then try this method below, this might help you to restore it back to normal.

Method 1: Fix bricked Samsung Galaxy S3 (AT&T SGH-I747) Flashing with original stock Boot Image

This solution may fix your phone if you have flash a wrong bootloader image from Samsung galaxy S3 GT-I9300 (International GSM)

Grab the boot image file odin flasher and USB driver
Stock Boot Image - Download
Odin flasher – Odin3_v3.07
USB Driver -   Download

Use PC with Windows OS (Odin will not work on Mac and Linux OSX)
Recharge your battery using external battery charger since you can’t recharge the battery within the phone for it is already bricked.

1. Run Odin on your PC desktop
2. Boot the Galaxy S3 into download mode screen for Odin.
Turn it off, once completely shut down  hold down the ‘HOME’ + ‘VOLUME DOWN’ buttons and press the ‘POWER’ button for about 2 seconds until a WARNING! Screen appears. Press the ‘VOLUME UP’ button to continue or enter Download Mode.
3. Connect the phone to PC via USB. Then make sure you can see as phone “Added” in Odin log box or highlight the COM:ID once the device is detected,
4. In Odin window, DO Not tick ‘RE-Partition’  only Tick ‘Auto Reboot’ and ‘F. Reset Time’ and nothing else.
5. Now simply click and load the boot image boot-stock-att-sgh-i747.tar on Odin’s PDA button.

If the phone will then reboot to normal mode then its you’re lucky day. If the bricked problem still persists, refer to the below method.

Fix bricked Samsung Galaxy S3 (AT&T SGH-I747) Flashing with Original stock ROM or Firmware

Now, if the phone still doesn’t respond after restoring the original boot image, this time we are going to flash its full packaged firmware by using Odin flasher tool and the original factory stock firmware itself provided by Samsung.
Grab one of these original Stock Firmware:
Choose SGH-I747 Stock

Again make sure the battery is fully charge (recharge the battery using external battery charger)
1. Run Odin on your PC desktop
2. Boot the Galaxy S3 into download mode screen for Odin.
Turn it off, once completely shut down  hold down the ‘HOME’ + ‘VOLUME DOWN’ buttons and press the ‘POWER’ button for about 2 seconds until a WARNING! Screen appears. Press the ‘VOLUME UP’ button to continue or enter Download Mode.
3. Connect the phone to PC via USB. Then make sure you can see as phone “Added” in Odin log box or highlight the COM:ID once the device is detected,
4. In Odin window, DO Not tick ‘RE-Partition’  only Tick ‘Auto Reboot’ and ‘F. Reset Time’ and nothing else.
5. Now load the I747UCALEM_I747ATTALEM_I747UCALEM.tar.md5  in Odin PDA button.
6. Click on “Start” to flash the stock firmware
7. Wait until the flashing successfully finishes, you’ll just see a word ‘PASS’ in odin.

If the phone reboot normally, its then a success story, and if not, there’s nothing I can do to add more but just recommend  you to contact or visit your nearest service center.

You may then perform factory reset if necessary, to get rid of bootloop, stuck on welcome screen logo issues.
- Turn off the phone and set it into recovery mode
- Press volume “volume up, home and power buttons”
- Once in recovery mode, perform full wipe
- Select ‘wipe data/factory reset’
- Then also select “advanced” and clear the Dalvik cache too
- Lastly select ‘reboot system’ now and and wait ’til your phone completely reboot in normal mode.

How to Avoid bricking your Galaxy S3 I747

Don’t Flash other variants Stock ROM and kernels. (If you find any instruction on the web or forum read it carefully or ask something that you don’t understand)
Don’t not ever use root kernels and boot images, from custom ROM builds for GSM or GT-I9300 for it is very different from U.S and Canada Galaxy S3 variants.
