So today i was updating my S3 to 4.1.2 update and in the process i thought of checking where it downloads the firmware. It downloads in the c:\users\[user]\appdata\local\temp
here it downloads as a file with .tmp extension. Keep pressing F5 and the file whose size is changing is that firmware file. Then after download it extracts the file to a zipfolder. Inside there's a md5 file which is around 1.24gb for me. This is the odin flashable file and you must back it up before the Kies is able to complete the updation process as after it has completed it will delete the file. The main aim of this is because as i dont have a hotfile premium account i cant download from sammobile as the file always stops in between. With this method you can easily backup your firmware for the next time.
