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 4.3 based ROM and wants to return back to official stock then you should also flashed the 4.3 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 4.3 K JB based ROM. Once you’re on 4.3 you must stay on 4.3, but do not ever restore your phone to the older version. We cannot revert back our firmware to the lower build due to the secured bootloader.

Important Note: Downloading a firmware packaged should match to your phone model number. These files are exclusively for T-Mobile Galaxy S3 SGH-T999 & SGH-T999L 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.
