301279 not working

The information for this post was obtained by decompiling the
deodexed system image of the firmware shown below.

I9300XXALE8

Base Firmware: I9300XXALE8 (4.0.4)
Modem: XXLE8
CSC: OJVALE7

301279 || 279301 SendData('\001', '\001', '\024', '\000', '\000');
32489 Ciphering Info SendData('\001', '\001', '\006', '\000', '\000');

[/SIZE][/CODE]Enjoy!

Hi sir,
i'm currently using dxlf3, before (on my previous phones) i have been using this menu (*#301279#) but with my galaxy s3 i cant us it anymore... is there like an alternative for this said option. because the country that i am in, 3g connection doesnt seem to be one of our best buds. so with the auto switch it mostly favor utms but whenever it's connected to hsdpa or hspa+ streaming has never been that good...

so i plea to anybody who can give us an update about the code... id greatly appreciate it. i'm not that techy i just learned if from a dude in the samsung service center in our country. they doesnt seem to know what the deal is with ics

What you wanna do?
Disable HSPA but leave 3G on?
*#197328640# => DEBUG SCREEN => PHONE CONTROL => NAS CONTROL => RCC(HSPA)CONTROL => CHANGE REVISION

Id like the other way around. I was able to get into the service mode. But still it kicks to 3g. I chose release 5. But when i see the select display revision, hsdpa "0" hsupa "0". The thing that i wanted to do is
Disable 3g(umts)
Leave open hsdpa

Thanks!

I cant make a screenshot using my daughters phone. On hers there is an option to turn on/off hsdpa and hsupa. Using 301279 i also used that code before with no luck. Here is screenshot of what always happens when i do it. And when you check the status of it. Both shows value of 0

Confusion
I have also found on other samsung devices that u can run the same commands via shell by doing an

am start -n com.samsung.ServiceModeApp/.PlaceActivityorclasshere

it works a lot to access things that may be hidden and the dialer doesn't necessarily have access to due to permissions to run

jd-gui is a fantastic little program. i used it before but the problem is that the class names that is comes up with arent always clear as to what they do.

also newer sim cards have security features and cannot be cracked as easily. do some research on it as mine is a little old, but the process isnt cut and dry.

App to store and execute secret codes?

Hi all,

so far I used "SGS Info" app from my good old Galaxy S1 also on my S3.

But it seems, with Firmware XXBLG6 onwards, Samsung changed something in the dialer, so the app cannot successfully pass the codes on to the dialer anymore.
The same applies to another app I tested quickly (Hidden Features FREE ICS Edt.).

So my question is: Does anyone use an app (ideally where I can configure my own secret codes) to execute it in the dialer? And still working with latest firmwares?

Many thanks already!

Andi

Unfortunately, Samsung did not change something by accident and all the apps are broken now, but samsung actively implemented a check if the code is applied via 3rd party app and block these 3rd party codes .....
...after introducing additional system app permissions for their secret codes within ICS, skipping some functions within the galaxy S3 firmware and now this new implemented check, I don´t know if there is an other hack to use these codes via an app on the GS3 ....you can still use these codes manually via dialer or adb (not tested by myself ), but it seems that samsung really wants to block all 3rd party apps ...THANKS SAMSUNG !

    "Secret Codes" and Hidden Features

    Hacking for "Secret Codes" and other hidden phone features.

    Skill Level: Easy

    Posting

    ==================================================
    Do NOT post general questions/requests on how to do
    this or that, they will not be answered, simply
    because we don't know yet. Rather try to find out
    by yourself and share your results.
    ==================================================

    Purpose

    To find all "Secret Codes", special properties and other hidden phone features
    and settings, used in the GT-I9300. The secret codes are not so secret, but
    are often used to activate and manipulate many settings, such as debug modes,
    network connections, factory test modes etc. It is an unfortunate choice of
    words but we will stick to this definition nonetheless for simplicity, since
    it is also used in the source code by Samsung and AOS. Do not confuse secret
    codes with VSC (Vertical Service Codes), USSD (Unstructured Supplementary
    Service Data) or other MMI (Man Machine Interface) codes.

    Although there are many "standard" codes common to many Samsung phones, they
    do vary to some extent. This is because their functionality often depend on
    the particular hardware, in particular the baseband processor (aka radio, DSP,
    BP or CP) and the multiplexer chips that switches the various internal USB
    paths, for example between MHL, BP and AP.

    This is an informative reference thread on these features. If you have
    relevant additional information you'd like to share, please post it here.

    Background

    From the Samsung Galaxy S2 experience we have gained the following
    understanding when it come to the Factory/Service Mode menus and the
    PhoneUtils applications. We are still to work out if this is still true for
    the SGS3.

    But first it is worth to note, that due to the more complicated, but better
    organized phone applications in ICS, the way to enter secret codes have
    changed from GB versions. Now all secret codes have to be prefixed with
    "*#*#", followed by <code> and post fixed with "#*#*". [Note-1] However,
    according to the GT-I9300 Service Manual, there are two codes that should work
    without post- and pre-fixes. They are *#1234# (version) and *2767*3855#
    (Factory reset! It will wipe your phone instantly, NO warnings, no going back,
    no way to cancel.) [Note-2]
    ==================================================
    Newbie Practice Box
    Go to your phone dialer and "dial" the following string:
    *#*#197328640#*#*
    This will trigger the Service Menu.
    ==================================================

    This same effect can be accomplished directly on the command line, with a
    direct URI broadcast call to the application receiver via:

    Code:
    [SIZE=2]am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://1111[/SIZE]
    Second, it is essential to know that the actual program code (read
    assembly/machine code) for the Engineering / Service Mode menu, is actually
    located in the baseband processor firmware. What you actually see when you
    enter this menu, is just a java based wrapper application, that make direct
    function calls through various entry points, in the baseband kernel/firmware.
    What does it mean? When you enter a specific "secret code", the wrapper
    application (e.g. ServiceMenu.App) deciphers the code to a particular menu
    entry in the baseband processor, where it is executed and whose result is
    output to the wrapper application.

    Third. Apart from hardware differences, because of the baseband firmware
    dependance, the set of working secret codes will differ somewhat from your
    location, depending on:

    • Your Modem firmware
    • Your AOS version (ICS 4.0.1, 4.0.4 etc.)
    • Your CSC version (Regional codes)

    Special Notes

    [Note-1] This can be seen in the handleSecretCode() function in the SpecialCh****quenceMgr.java code.
    [Note-2] These need testing and confirmation since they clearly contradict [Note-1].
    [Note-3] Apparently the Samsung Galaxy S3 will come in at least two versions:

    1. The GT-I9300 (FCC-ID: A3LGTI9300 )
    2. The SCH-I939 (FCC-ID: A3LSCHI939 ) [Possibly the LTE version]

    Special Files

    As we know from other Samsung Galaxy class phones, there are a number
    of files that can be created or modified in order to activate certain
    functions. Here we list those found to date. Please post if you know
    of other ones!

    Apparently setting the "SubscriberID" (IMSI) to "999999999999999" also
    activates certain test features. A sim with this IMSI is also known as
    a "Factory SIM". However, if the SIM IMSI starts with either "45001" or
    "00101" it is a "Test SIM".

    [See: ServiceModeApp.apk:phoneUtils.java:isFactoryMode() or
    FactoryTest.apk:ModuleCommon.java:isFactorySim()]

    Code:

    NOTE: In the table above, I have replaced printed UTF-8 (U+NNNN) characters with '\uNNNN'.

    As you can see in the table above, most of the hidden codes are just shortcuts
    into various sub-menus (third parameter) of Service Mode application. However,
    this does not exclude the use of other hidden codes, that can be used or detected
    in other applications.

    From a different file we have a some additional codes.
    (Not including already covered or overlapping codes.)

    These may not always work, since some of them depend on certain "Sales Codes"
    or factory IMSI numbers, through statements like:
    Code:
    if ((mSalesCode.equals("CHM")) && (str.equals("827828868378")))

    But these were only codes found in two files.
    So there are probably many more codes to be found!

    HOW TO (find new stuff)

    So how do you find new codes?
    Well Google it! Then consider getting the following tools:

    Then what to do?
    The brief version. (For full version, see "References" in OP above.)


    1. Download all the tools shown above.
    2. Download the deodexed firmware images (see post#3)
    3. (If in Windows) Double click the sgs2toext4.
    4. Drag and drop the system.img file to the sgs2toext4 "drop window".
    5. You will now have a system.img.ext4 file, open this file with the LinuxReader tool.
    6. Save entire filesystem (from 5) in a new folder. Close.
    7. Go to the folder containing the *.apk(s) of interest.
    8. Make sure dex2jar.bat (win) is in your path and run it on your interesting.apk like this, for example:
      Code:
      ./path/to/dex2jar.bat Samsungservice.apk
      This produces a new file: Samsungservice_dex2jar.jar
    9. Extract (7zip) this file in a new folder.
    10. Go to that folder in command line and enter the appropriate "jad" commands. For example, to decompile all class files globbed by Phone*.class and put the decompiled sources in the "src" sub-directory, do:
      Code:
      jad -o -r -sjava -dsrc Phone*.class
    11. Go to the source directory (../src) you just created.
    12. Enjoy your *.java files!
    Alternatively you can deodex on your own...but don't ask me how to do it.
