The development for the AT&T I747 has been discontinued by the developer. Thank you for your support.
WARNING: YOU WILL PROBABLY BRICK YOUR PHONE! The possibility is very real. Samsung made it difficult to update the firmware with the introduction of Knox.
This is a full firmware update!
I'm not the best at giving directions. I do expect a certain level of knowledge and skill on your end.
I did try my best to safeguard you from bricking your phone. The install scripts will fail with an erron 7 if something is wrong.
More then likely if it fails... you are on very old firmware version. I suggest you double check your booloader version and if it is older then the latest Odin update available on http://www.sammobile.com/devices/specs/SGH-I747/ Update to DLK first.
Or try updating the firmware incrementally. If your firmware is MJ2 or below, it is safe to flash any previous firmware without fear.
All available recovery flashable firmware that I have https://www.androidfilehost.com/?w=files&flid=10522

Knowledge of flashing and using odin.
Checking the bootloader.
If your not sure what bootloader your on.
adb shell getprop ro.bootloader exit exit <--- the second exit is to completely terminate the shell connection.

Reboot phone fully then reboot back into your custom recovery.
2. In a custom recovery flash the MJB to NE4 firmware update. https://www.androidfilehost.com/?fid=23501681358559161

While working with spagman72 on debricking devices we figured out no amount of ODIN will be as effective as a full wipe in the stock S3 recovery.
A wipe in the stock S3 recovery will also fix any sdcard encryption issues as well.
Now reboot back into the stock recovery and do a factory reset.
5. Use odin and flash your preferred custom recovery again.
