Was going through many threads and found B360E Sim Unlock
an issue , may be people have done it before but no details
Tried on other tools says unlock still is locked
Tried on Octopus ..had the same issue .
Flashed on Z3x stuck on Exception Error (green screen after logo)
Got final solution and recovered handset with unlocked Sim . 😀
Only Issue is language for Indian customers hope Octopus team will update
