Cannot access service mode on Sammy 4.3
I'm currently having a problem with entering service mode
When I was on 4.1.2, I usually used *#197328640# or *#0011# then press menu>back to go to main menu of service mode that would look like this.
However, once I updated to 4.3, I could not use *#197328640# code anymore. *#0011# would send me to the page that shows cell site data, but I could not go back to main page.
I need to use service mode to set certain frequency that I would want my phone to connect to i.e only connect to WCDMA 2100, not 850 or 900.
Furthermore, under service menu, I could check whether WB AMR was successfully enabled or not.
Already tried replacing servicemode.apk from 4.1.2 rom with no success.
Anyone know how I could enter service menu on 4.3 sammy rom?
This menu wont' come up on Omega, DrKetan and Official Sammy 4.3 rom.
