Every time you make a new software update there is a firmware number that appears. If you read it for the first time it seems none-sens. Ok, there is the number of your device but what's the other part? Well, we will tell you what it means, as you to know what they want to say.
It's important to know this number, as to know if you got the latest update or which update can have bugs in it. Let's take an example. The latest version of firmware for Samsung Galaxy S4 is I9500XXUFNC1
. As you see, this number can be broke down in three parts. First parts is the device model, the second part is country/language and the third one is build date information.
So, in our example, I9500 is S4's number internationally known. The next letters are the country code/CSC - customer software customization. You can find the CSC code here.
Next letter, F, is related to the original Android firmware based on Android 4.4.2.
The last part is NC1. This is the information about the built data information of the update. The first character is for years, N meaning 2014. The next letter is the month. This are translated like this: A it's January, B- February, so C is March. The last number is 1, this is the revision code or version number. This means that the firmware from the example was made in Marc, 2014, the first version.
