I never could figure out what the "SendData" Java code referred to. Maybe it's within the ServiceModeApp source. Anyway, sending the broadcast with the "am" command requires root, and the equivalent code in Java is:

Code:
Intent intent = new Intent("android.provider.Telephony.SECRET_CODE");
intent.setData(Uri.parse("android_secret_code://1111"));
sendBroadcast(intent);
The app needs system (aka root) privileges so a normal app doesn't have a chance of calling this. I've used the RootTools library to give an app root privileges.

I normally don't beg for Thanks but I spent hours banging my head working this out. If this saves you some time spread the Thanks button love

For entering Service mode (and more) on 4.2.2. stock SE enabled Samsung S4's, checkout my new thread:

Getting into Service Mode (SM)

On this particular model, you have to do this:

Go to dial pad and enter: *#0011#

This will initially take you to Service Mode and showing you
various signal status items, by default. But it's a locked
entry. So to unlock and go to the Main Menu do this:

==> [MENU] + [Back]
==> [MENU] + [Key Input] + "Q"
==> [MENU] + [Key Input] + "0000"
==> <wait ~5-10 seconds>
Now you can hit the thank you button below!
I have not seen this solution anywhere else, and
it required some reversing..[/CODE]


Thank you!!! Brilliant find!

I confirm that this trick also works on the GT-I9300 with Android 4.3 (tested with XXUGNA5). The service menu is back!

Hello,

You can use Shortcut Master app to get a FULL list of ALL secret codes in your device. And you can also get all of codes WORKED.

Install Shortcut Master --> 'Secret Code Explorer' menu --> tap on the code --> Select 'Launch 0' to launch the code.

P.S.: This app requires ROOT permission to launch the codes.

Hi!

Do any of you guys know how can I change the language on this menu? my phone is on English, my rom is based on Italy stock based rom rXtreme JB4.3 by @r_i_x and oh the other menus is on english like cheking the IMEI or other system menus like LCD check WLAN check this photo right here is the Menu used by my Telco provider to check balance or promos the weird part is it should be on English because I'm from Philippines and because I'm not Chinese and the phone is made in Taiwan. Give me ideas please been looking on google and can't find my luck thanks in advance!

*#301279# HSDPA/HSUPA Control Menu- does not seem to work on my Note 4.
I bought my phone on Wind mobile and unlocked it so that it can run on Bell. At first I couldnt get LTE working. I solved that issue using 2263 and enabling band 4.
Right now I am only able to get 3g signal during phone calls or weak LTE areas. Any help would be appreciated.

I found this menu also on i9300 4.3 rooted, omegarom v61. But did you manage to find an option to enable AMR-WB?

Hi I have tried looking into galaxy core prime(g361h) apk, but can't find the codes coz they must've hidden them further.
Attached are 2 apks, if you find the codes please post the file they were in.

I suspect in string resource files, I used apkstudio to decompile.
Please help out if you can.
Thanks in advance.
