Can't access Service Mode S5 mini

Hello!
I bought an s5 mini second hand, turned out to be locked to an overseas region.
Been reading here and tried to access the service mode without any luck
I tried this

Dial *#0011# on your Galaxy S4 in Phone app to launch Service Mode. Ok, got here
When the Service menu is launched, tap on Menu (left soft key) and select Back from the list of options shown,
Tap on the Menu key again and select Key Input from the options. This will show you a pop up box. Tap on it, enter 1 & press OK.
Tap on the Menu button yet again and select Back. This should take you back to the Main Menu of Service Mode.

I do this sequence but stays on same screen

Also tried the same on *#1111#

or

*#197328640# nothing!


Thanks!
