i FIX THIS PROBLEM with this process

when you do the unlock don't select skip backup/restore NVM

because when the unlock is done you dont have service, in the same time you do

is select the bottom write QCN and select the file SM-G730A_M8930B..... this file fix the problem in the not network, this file is the backup about the cellphone.

for root the cellphone i uses VRoot_1.7.0.3882_Setup.exe this works for mi
