Hello! i am new to the forums and i have a samsung galaxy s4 and i have it for about 2 years now and from the very beggining i got it it was version 4.2.2 and now its still version 4.2.2 it dosent want to update!! every time i scan for an update it says the latest updates have already been installed and this is very annoying i looked everywhere for how can i update but the only good method i found requires ROOT (odin) and i dont really want to root it and lose my phone if anyone could come up with a solution for me i would be quite happy!!
 
Odin is the flash tool used on Samsung devices and works with phone in download mode. No root required.
There is a app at the Play Store called Sammobile Device Info. It will tell you your Product and CSC code. We can use it to select the correct firmware.
 
Here we go couldent take a screen shot sorry!
Product Code: GT-I9505ZKABTU
PDA: I9505XXUBMGA
CSC: I9505OXXBMG3
 
Sammobile app should also list current firmware version or go to settings- about phone and list build number and baseband
