s4 service menu

[Alex Hriscu]

Good day guys, i have found out this information and service menu regarding Samsung related devices:

From the Dialer :

*#0011#
MENU -> press Back
8 (Phone Control)
3 (NAS Control)
5 (Revision Control)
2 Change Revision
2 Release 5 (HSDPA ONLY)

Screen should read, HSDPA ON, HSUPA OFF

MENU -> press END

My problem is, the service menu shows, its showing some data there, im pressing "menu" button, then from the dropdown menu im pushing on "back" but the initial display it doesnt change anything, i have the same display as the moment i accesed the service menu, and i dont see where i can input those numbers to get to that network setting. I am curently using the I9505 version of the SGS4. If someone knows how to do this please let me know. Thx

Try
*#0011#
MENU -> press Back then menu key go to key input screen pops up now type Q0000 and then hit OK those are zeros as in numbers so capital and 4 zeros that should get you too where you need to be!
