cry a little, maybe the phone will accept your apologizes and resurrect from the dead
again it may not work so don't get your hopes up to high ITS A TRIAL AND ERROR situation WITH HARD BRICKS...........
some people have successfully debricked their device, so again you have to be patient and know exactly what you are doing and dont panic
Remember Mobiletechvideos.com can fix it in less than 25 minutes depending on your phone :laugh:and they are affordable :good:
Your pretty much stuck if you can't recover via SD card.
Remember there are a lot of options for JTAG repair, research local repairs by Kijiiji and also places like Mobile Tech Videos. Always search for legitimacy and best price.

Can’t access to Download Mode or Recovery Mode after bricking AT&T Galaxy S3 i744 4.3
Hi I have (had) a AT&T galaxy S3 i747 with android 4.1.1

Because the phone is in another country I couldn’t update it by OTA to android 4.3
So I started to read forums that said how to Update AT&T S3 i747 to android 4.3 (I747UCUEMJB)
The S3 was not Root
I installed all the phone drivers in the computer
This is what I did: (http://forum.xda-developers.com/showpost.php?p=52341582&postcount=38)
- Use Odin 3.07
- Check Auto Reboot and Re-Partition, and uncheck all the boxes
- I put my phone in USB debugging in the developer options
- I turned it off
- Started to put the phone on Download Mode pressing volume DW+home+power button at the same time
- In Odin on the PDA box I checked and loaded the file .tar.md5 (I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5 )
- Pressed the button Start
The installation seemed to go right, the program never showed anything weird.
When the Programs finished the installation the phone turned off and then turned on and show the logo of android (seemed to be lying down or inclined) and after that it turned off.
The computer showed that something was connected (QHSUSB_DLOAD) but couldn’t install any driver, so I disconnected it of the computer.
I couldn’t turn on the phone :crying:, I took the battery out and put it in and tried to start the phone and nothing happened, I tried pressing any button to access to recovery o download mode and none of this worked.
I started to search forums that talk about restart or turn on a brick AT&T S3 i747
I found one (http://forum.xda-developers.com/showthread.php?t=2549068) that said to download a image (debrick-SGH-I747U-CUEMJB3.img) and using the program “Win32DiskImager” to put the image inside of a micro SD to make the phone turn on,
I put the micro SD inside the phone and when I pushed the power button for almost 3 seconds it Turned on , the phone seems to be fine an it has android 4.3 (I747UCUEMJB) installed.
I can use it normally so far.
But the problem is that I can’t turn on the phone if the micro SD card is not inserted on the phone.
Without the micro SD inside don’t show any sign of life
When the micro SD is inside I can turn on the phone and use its apps.
I have tried to enter to Recovery mode or Download mode with the micro SD inside but the phone only show what its supposed to happen for 1 second then turns off and then turns on by its own (after that I can use it normally)
Does anyone know how can I Fix my phone ?
How can I boot my phone without using the micro SD card?
How can I access to download mode?
And if I could access to download mode what should I do next ?
The only files I have now are:
Odin3 v3.07
I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5(905 Mb)
debrick-SGH-I747U-CUEMJB3.img (80 Mb)

It's been a while sorry about beinging away.
A guy who says that have a JTAG service tried and coudn't recover it. So I left it there because it have a broken display and a broken firmware and it' is from outside Brazil and after the FIFA CUP Anatel will lock operation of devices that models are not sold on Brazil and I747 is probably included on the list.
So i gave up from my phone and bought a Nexus 5.
The case is closed!

Here's what you can do to get the device back to working and booting normally. If the Odin flash failed first time, you should not use this flash again. Instead you should use custom recovery to flash a complete 4.3 stock restore image.
1) Download the stock restore image from the following thread. I always prefer to use TWRP and thus, the TWRP image, because of the easier user interface.
http://forum.xda-developers.com/showthread.php?t=2658486
Save the file to a location on your computer.
2) Download the Odin flashable TWRP Tar file for custom recovery from the link below ....
http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.1-d2att.tar
With the debrick card in your phone, boot to system as you have been doing. Connect your phone to your computer with a good quality micro USB cable and copy the stock restore image you downloaded earlier to your phone. Be sure you remember the stored location.
3) Power off your phone and, with the debrick card, boot to download mode. If you cannot use the Volume Down, Power and Home button combo to boot to download mode, you may need to get a USB jig.
4) Once you are in download mode, connect your phone to the PC, open Odin v3.07. Make sure Odin recognizes your phone. Do not check or uncheck any boxes but leave the defaults as is. In the PDA box, load the TWRP Tar file you downloaded earlier. Click on Start and wait for flashing to complete. When you get to Pass, disconnect your phone from the PC and pull out the battery to stop it trying to reboot.
5) Replace the battery and with the debrick card inside, boot to Recovery mode by pressing the Volume Up, Power and Home buttons. If you do this right, you should be able to get to recovery mode.
6) Select Install and navigate to the stock restore zip file you saved to your phone earlier. Select this zip and swipe to confirm install. Wait for firmware installation (flashing) to complete.
7) Clear your cache/dalvikand reboot to system.
Try booting without the card. If the above process went as described, your phone should be booting normally. Good luck!

Okay. At least, we are almost there. Try booting into recovery mode and doing a hard wipe/reset. If this doesn't work, then you could try reinstalling the 4.3 stock firmware. You may need to reflash custom recovery as the initial flashing would have returned you to stock recovery. If you have to do the firmware flashing again, please make sure you clear your cache/dalvik before rebooting to system.
happy to see this thread resolved, this is what XDA is all about, no matter how fd up something sounds, a community like xda will find a fix for it even if it takes months
And the award of the Q/A thread goes to Larry and everyone in this post for trying and failing but succeeding at the end :laugh:
anywayz happy rooting and be careful, no-one wants to end with a brick cheers and keep this place awsome

Hey Larry2999 I want to really thank you for your help it was so helpful, actually I discovered that the battery of the Galaxy S3 was failing thats why when I turned on the phone it turned off after a seconds althoughthe battery was charged, so I connected the charger to the phone and it started normally.

Did you try getting into download mode with the 3-button combo (Volume Down/Power/Home)?
Its been a long time since I booted my Galaxy Note-II (GT-N7100) as I use an iPhone and Nexus 5 as my daily drivers.
The phone wont boot past the Samsung Galaxy Note II GT-N7100 logo. I am able to access the recovery and download mode as well, and I have flashed the latest stock rom from Sammobile using the Odin. The flashing was successful. however the phone doesn't boot past the logo. Also the phone will not power up unless connected to a PC, it wont power up even when connected to a charger and will immediately shut down when the USB cable is disconnected from the PC. I flashed TWRP 3.0.2 Custom Recovery using the Odin and tried installing CM 13 based Rom through the mem card, however the log reads patching image unconditionally and also that "Failed to mount /system" (invalid argument). The phone when restarted into recovery can no longer mount the /system partition. However on flashing the stock rom using Odin, the /system partition is available for mounting. The recovery log also shows MTP enabled, but my PC doesn't detect the phone when in recovery, it only detects the phone in Download mode. I have the Samsung drivers installed. Since the phone is not being detected in recovery I am unable to use the adb.
I am out of ideas and request your suggestions other than approaching a service centre.
If I can somehow access the phone via ADB, I might be able to check the memory partitions for corrupt units, and possibly create a custom PIT file to repartition and suit the available memory units.
Try this: open Odin, uncheck everything except f.reset time. Connect phone and flash stock ROM. When you see the word reset in the status window, remove USB cable, remove battery for a few seconds, replace battery, immediately boot the phone into recovery mode, factory wipe, and boot the phone.
Could the battery be defective or dead?

Try this: open Odin, uncheck everything except f.reset time. Connect phone and flash stock ROM. When you see the word reset in the status window, remove USB cable, remove battery for a few seconds, replace battery, immediately boot the phone into recovery mode, factory wipe, and boot the phone.

Thanks a lot.
Tried your method and finally the phone has booted into the OS.
Had to replace the battery with another spare one in the process.
However the phone is still not being detected by the PC unless it's in Fastboot/ Download mode.
When connected to a computer, does anything appear on the phone screen? If you're using Windows, nothing new appears in device manager?
sorry to jump in this thread but i am having a similar problem
my completely stock tmobile note 2 is stuck on the samsung logo
i have never flashed it or done anything to it
my phone was working really slow, freezing up and battery draining fast
so i did a hard reset and it fixed the problem of running slow and freezing up for a week or so but battery drained fast
so i bought a replacement battery from ebay and installed it and the next day i restarted my phone and it froze on the samsung logo
i tried turning it off and on and still the same thing
any suggestions or should i start a new thread?
fyi i am a noob
Hi everybody, yesterday I was playing with my old Galaxy A50 trying to install a custom rom unsuccessfully.
I repeated the procedure three times installing TWRP and then Havoc OS but every time I tried to reboot from TWRP to OS I was stuck at the warning screen saying that the phone bootloader was unlocked and booting into download mode to reflash TWRP was blocked as it showed "only official binaries can be installed" (yes I installed Samsung disabler but still).
Still I was able to get the phone into download mode and reinstall the stock firmware as it seemed to be the only way to install and boot TWRP.
But at 4th time repeating the process I got frustrated, shut down the computer and left the phone on the warning screen still connected to computer usb cable.
Then I got back and noticed the phone was off as the battery died.
Indeed the battery died, so I put the phone in charging and after it reached 100% I tried to boot into download mode again to reflash stock firmware.
But here's the strange thing, I cannot boot into download mode anymore as pressing vol up+vol down while connecting usb cable, shows the lightning charge logo for 5 secs and then reboots infinitely with the same pattern.
If I force reboot by pressing vol down+power it shows the Samsung logo with the warning below it, then skips to another screen with another warning suggesting to press power button to continue (which does nothing) and after a while reboots to samsung logo.
So it doesn't seem it is bricked, it looks more like a battery controller fault, so I tried to detach the battery flex from the board, hoping it would reset the controller but it's still the same.
Also I tried with the flex detached and still no download mode is possible.
Was the download mode somehow erased? (if it's even possible considering it's the motherboard firmware)
If you need photos, videos or even a call on zoom, Skype, webex I would be glad to show you
same i got the same problem i can't find nothing for this when i press volume up and down and put the otg cable its simply charges but it gets stuck on the logo image there's no way to fix this but the only way is to open the phone,change the emmc and put one from samsung,close the phone flash a custom rom and you are done.
If you can enter recovery, do it. As soon as your phone gets into it, select the power off variant and then try to enter the download mode.
It seems like you did not unlock the bootloader, did you?
The bootloader Is unlocked i can't enter in the recovery because the phone locks on charging logo and its fully charged but when i try without charger It doesn't start.
