I am installing stock rom because of get warranty back (now i am running Archidroid).
I don't know which firmware I should choose. My actual region code is XEF (stock recovery is saying that it's XEF. Archidroid is saying I9300ARCHIDROIDARCHIDROID but I live in Czech Republic so It should be XEZ. Than, I don't know which CP number i should choose.. My actual is I9300XXUGNA8 which is Uzbekistan or Kazakhstan (wtf? :D).
What will happen when I flash stock firmware with XEZ (csc) and I9300XXUGND5 (CP)? Thank you for your help. I am noob. I was googling and I found just what is AP, CP and CSC. But not what happen when I change it.
I have international version of Galaxy S3 (GT-i9300)
Thank you in advance
