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

AOCV fw was the last one that I could open the service menu, since then it never opened. I wonder if it's disabled by Samsung in new updates?

I'm wondering if this is the case, since I was able to access it yesterday, but not today. I just received the latest update this morning.

So what happens if, say, someone set their phone to a certain LTE band and they not want to restore that setting to "automatic"?

Its based on your firmware CSC probably... Some regions have it and some don't.

Out of the latest versions of FW (AODG & AOE3/4) I've tried: France, United Arab Emirates, Vietnam, Thailand & Slovenia. None of them allow you to access any service mode menus. Using old FW like AOCV and the service menu works.

Can anyone at all confirm service menu working on AOE3 or AOE4? Try *#0011# in your dialer.

Do you know which file/directory are changed by Service Mode BAND SELECTION?
Because we could go back with OCV firmware, do BAND SELECTION (in example LTE/WCDMA ONLY) and see what files/strings are changed, and then manually change files with latest firmware.

After the last software update, I am able to access the service mode with *#0011#, but not band selection with *#2263#.

Sent from my SM-G920W8 using XDA Free mobile app

Which software update version is that? There are many versions for many regions.

Guys *#0011# STILL WORKS... but this ONLY shows some info about connection

With SERVICE MODE, I mean modify every setting of our Galaxy S6 (force band selection, etc)

I flashed AOE3 France, it didn't work. I just flashed AOE3 United Kingdom and *#0011# menu shows now. But to choose bands etc, I don't know how to do that.

Nope it's originally from Vodafone Germany and the service menu worked on the original rom too.

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 !!!

    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 .
