At first try to root samsung J700F. completing root set can't open. that means software fault. firmware 5.0.1 (multi file) write on set with z3x, as a result set make open but Baseband Version Unknown. then write 6.0.1 firmware (single file) on set with odin. now set is ok but sim slot 1 can't registered network. Before root both sim slot was ok. what can I do for this problem?
