mobile network service loss after update from samsung server

i update my s5 mini dous when requested, and since then my phone do
not see mobile network service again, and i have tried to install
another firmware maybe it ll restore its mobile network service since
i have restore it to factory settings many times. i tried different
version of odin and other stock rom software but all fail... i think
something like QUALCOMM SECUREBOOT ENABLED is preventing it to accept
new os on the device... please is there a way round or way to break
through this... thank you.

my device version is SAMSUNG GALAXY S5 SM-G800H/DS.
