Thanks for the replies by the way.
That is the best and safest way to do it on a rooted phone if you need to keep to your phone's original firmware.
1. Ascertain your phone's, "Version". See, "Tip:" in #2.0 of the Rooting Galaxy S4 - Dummies Guide
2. Go to the SamMobile
site and register and then enter your CSC code minus the last 3 digits into the, "Search device here..." box in Firmwares. This will show you all the stock Samsung firmwares for your device including the one you are on. Choose the latest firmware for your code and download it.
3. Extract the .tar file and flash it in PDA on Odin via USB cable. You will lose root as you are flashing stock firmware which has a stock un-rooted kernel and so will need to re-root again using the earlier guide.
Alternatively, if you are not worried about having stock firmware to match your own, which most rooted users aren't, you can just flash one of the pre-rooted DjeMBeY ROM's to get the very latest Jelly Bean release, currently MF8. See, DjeMBeY ROM's i9505 - Dummies Guide
. Please take the time to read all the instructions, carefully and thoroughly.
