3)Decompile Settings.apk

Code:

apktool d Settings.apk

4)Add new Item in You Device Info view
a)Open Settings/res/xml/device_info_settings.xml
b)Add after

Code:

<Preference android:title="@string/build_number" android:key="build_number" android:summary="@string/device_info_default" style="?android:preferenceInformationStyle" />

this

Code:

<Preference android:title="@string/your_rom_version" android:key="your_rom_version_key" android:summary="@string/your_rom_version_default" style="?android:preferenceInformationStyle" />

Code:

</resources>

this

Code:

<string name="your_rom_version">My Rom Version</string>
<string name="your_rom_version_default">My Rom Version Value</string>

c)Save File
6)Edit Settings/smali/com/android/settings/DeviceInfoSettings.smali
a)Find in file this

Code:

.line 83
    const-string v8, "firmware_version"

    invoke-virtual {p0, v10}, Lcom/android/settings/DeviceInfoSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;

    move-result-object v8

    invoke-virtual {v8, v11}, Landroid/preference/Preference;->setEnabled(Z)V

    .line 84
    const-string v8, "baseband_version"

    const-string v9, "gsm.version.baseband"

    invoke-direct {p0, v8, v9}, Lcom/android/settings/DeviceInfoSettings;->setValueSummary(Ljava/lang/String;Ljava/lang/String;)V
    
	.line 85
    const-string v8, "device_model"

    sget-object v9, Landroid/os/Build;->MODEL:Ljava/lang/String;

    invoke-direct {p0, v8, v9}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V

    .line 86
    const-string v8, "build_number"

    sget-object v9, Landroid/os/Build;->DISPLAY:Ljava/lang/String;

    invoke-direct {p0, v8, v9}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V

    .line 87
    const-string v8, "kernel_version"

    invoke-virtual {p0, v8}, Lcom/android/settings/DeviceInfoSettings;->findPreference(Ljava/lang/CharSequence;)Landroid/preference/Preference;

    move-result-object v8

    invoke-direct {p0}, Lcom/android/settings/DeviceInfoSettings;->getFormattedKernelVersion()Ljava/lang/String;

    move-result-object v9

    invoke-virtual {v8, v9}, Landroid/preference/Preference;->setSummary(Ljava/lang/CharSequence;)V

b)and Add before

Code:

.line 84
    const-string v8, "baseband_version"

    const-string v9, "gsm.version.baseband"

    invoke-direct {p0, v8, v9}, Lcom/android/settings/DeviceInfoSettings;->setValueSummary(Ljava/lang/String;Ljava/lang/String;)V

this

Code:

const-string v1, "your_rom_version_key"

const-string v2, "ro.yourromname"

invoke-direct {p0, v1, v2}, Lcom/android/settings/DeviceInfoSettings;->setValueSummary(Ljava/lang/String;Ljava/lang/String;)V

c)Save File
7)Compile Settings
a)apktool b Settings settings_new.apk
b)Open Base Settings.apk and Copy to setting_new.apk META-INF folder and AndroidManifest.xml
8)And the last
a)Rename settings_new.apk to Setting.apk
b)put new Settings.apk to your device
c)Move Settings.apk to /system/app and replace with old Settings.apk
d)Change Permision to rw-r--r--
e)add line

Code:

ro.yourromname=MyRomVersion.v3

to your build.prop
9)Reboot Phone!

Now you have Item in Device Menu which value can be changed without decompiling Layout Settings.apk
For example: I added "Wersja ION" value to android:title in string.xml and "CheQ.example" value to ro.yourromname in build.prop.
Screen:

Enjoy!
