A Few Questions regarding unlocks
hi guys i have a Rogers sgh-i317m and recently downgraded it from 4.1.2 to 4.1.1 and got it to work with Wind Mobile, I now want to upgrade it to 4.3 , if doing so will it kill my unlock with Wind Moible? and if not should i use odin to upgrade it or over the air?
My Last question is in regards to a thread i saw somewhere that said you cannot downgrade your sgh-i317 to 4.1.1 once you are on 4.3 , is that true? thanks alot
