Question Rooted GT-I9300 with 4.3, dialer (secret) codes won't work

I have problem with dialer codes. Even the simplest ones (*#06# or *#0000#) won't work.

I have upgraded from 4.1.2 to 4.3, and yesterday upgraded more recent version of 4.3 (I9300XXEMG4, I9300OXAGMK6, I9300XXUGNB4) but problem persists.

I edited /efs/carrier/HiddenMenu to contain ON and also tried adding the line to /system/build.props. Then shutdown and battery away. Still the codes won't work.

I have installed programs from Google Play to launch the menu programmatically, with no success whatsoever.

Any help would be highly appreciated.

Do I have to downgrade to 4.1.2?

PS. The bottom line reason for this is that the WLAN doesn't work because of the interference of another phone (S2+) and I would like to try and change the hidden properties and perhaps be able to use the WLAN with my phone.

As far as I know the only way the 2 devices can interfere on wifi is by having the same ip or mac address.
