if youhave octopus box then your problem will be solved
just try to write N910C cert via octopus and follow software instructions
after finish box will tell you that cert is not compatible with phone
(do not worry every thing is ok)
now just go back to z3x box and write your cert file or any N910C cert file and it will be written
do not forget to press thanks
