hi;
first your phone should be rooted.
you can use a terminal ( Terminal emulator for android from appstore) then put :
su root
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://IOTHIDDENMENU

Enjoy !

well
I have samsung Galaxy S4 GT-i9505 on 5.0.1 lollipop
I use code *#2263# to select any band supported by my phone in GSM, WCDMA and LTE categories
I use *#0011# to see the details network my cellphone is currently locked to

alternate to service menu corresponding to the code *#2263# on my phone is as follows
*#0011#
menu> back
menu> back
menu> key input> Q0000
press enter and wait for 5 - 10 secs
then press [1] UMTS
press [1] DEBUG SCREEN
press [6] PHONE CONTROL
press [7] NETWORK CONTROL
press [2] BAND SELECTION

and tada
u can select any supported band of GSM, WCDMA , LTE in your phone

1. root your device
2. use "Shortcut Master(Lite)" (free) or "Phone Info+" app to launch the code 2263; band selection works in this way with my S6 Edge G925FXXU2QOI7 Android 5.1.1 .

Thanks ALOT!!! This worked with Phone Info app Launched the code with "Launch 0" (1 & 2 didn't work for me) then picked LTE Part 1 connect All on My Samsung Galaxy Note 4 N910C!! Finally Forced Connection to 4G only, I'm getting a better 4G Connection than before (Automatic) with 1 more bar ? :)))

Hello!
I have a range selection problem.
This is how my menu looks like:
As you can see, I have no option to select (*) in GSM, WCDMA and LTE. Automatic mode is on, but LTE does not work, GSM and WCDMA work. If I go to the LTE menu, I can only select LTE All, while "Automatic" is disabled and GSM / WCDMA does not work. I cannot select the frequencies I need in GSM, WCDMA and LTE, there is no choice (*)

    I have an International SM-G920F but I can't open SERVICE MODE like I did with S4, Note 4, S5...
    (dial *#0011*, menu->back, menu->insert key, type Q0000 and press enter)

    And other codes found online don't work.

    Does anyone know how to open SERVICE MODE ?
    I need it for BAND SELECTION and other stuff...

    Thank you for Help

    But I can't get out to any of the other settings :(

    Hello, I'm working to fix and restore Service Mode and Band Selection.

    I need somebody with SM-G920F and FULL WORKING SERVICE MODE (I mean not only *#0011#, but also BAND SELECTION).

    That person, must root his own phone, and send me these files:
    - /system/csc/customer.xml
    - /system/csc/others.xml
    - /system/build.prop

    You can send me an email at [email protected].

    Let me know ASAP, Thank you all !!!


    Can u help me fix that?
