If it will be an official update for Romania (Vodafone), you can install it via Odin from Sammobile firmware list. CSC will be modified to the stock's one.
So if i change, for ex,to Spain CSC, and upgrade to official spanish 4.2 i will lose warranty? And to get back warranty i just need to get back to COA csc (because my phone has COA)?
Sorry i'm such a pain but i really dont wanna lose warranty by changing CSC!!!
