Wrong firmware

[phxperia01]

Hi guys, i would like to ask if what should i do if i flash a wrong firmware on my xperia z3+ dual. i flash a xperia z3+ firmware instead. i tried to flash the previous firmware but the dual sim setting is gone. is there a separate firmware for it? btw my phone is not rooted. thanks in advance.

download a different FTF file, but make sure that it is for the dual version and flash your phone again.
