UPDATE: DO NOT DOWNGRADE ! On latest software updates you cannot downgrade back to the older firmware build version due to locked-down bootloader. In-case you are in Android 4.4.2 based ROM and wants to return back to official stock then you should also flashed the 4.4.2 firmware build. Again, you cannot directly downgrade back to the old stock firmware version for it might break the bootloader if you already installed a 4.4.2 KitKat or 4.3 JB based ROM. Once you’re on 4.4.2 you must stay on 4.4.2 and if you are still on 4.3 only install the 4.3 or upgrade to 4.4.2, but do not ever restore your phone to the older version. We cannot revert back to the lower build due to the secured bootloader.

Important Note: A firmware should match to your phone model number. These files are exclusively for AT&T Samsung Galaxy S3 SGH-I747 only. Do not use these firmware files in-case you don’t really exactly knows where and when to use it. Use of these firmware files is solely at your own risk! Some OTA updates are not included here, OTA files can only be flash or installed via recovery. The list might be incomplete, if you couldn’t find what you’re looking for, then you are welcome to find it somewhere else. I’ve put all up together in one single page as these files are very useful to fix your phone in-case it is in bad status.
