Hi,

I have a Galaxy S4 GT-I9505 (Europe LTE) with Qualcomm Snapdragon 600.

Yesterday I rooted my phone with Kingo Android ROOT (One-click root, NO Odin). I had installed the default rom from Samsung which you get when you buy an S4.
Now I have Android 4.3, but 4.4.2 is going to be released soon in my country (as other European country's already can download it).

How can I update my Android version without 'destroying' my phone? (I want to keep the root).

Regards,
Michael
