[Sony Ericsson XPERIA X10 Mini] pongnamu:
Step 3 Editing Build.prop

There is build.prop in your system, and we will modify that file.

You have to have Notepad++ to open it.

1. Open build.prop with Notepad++.

This is build.prop from my SlimROMs+ R3:

2. We are going to change lines with orange color.

Above lines explained:

ro.build.id= Write your ROM name here

ro.build.display.id= Write your ROM name here (It will be displayed in Settings>About Phone)

ro.build.version.incremental= Keep this basic principle: eng.YOURNAME.YYYYMMDD .HHMMSS (Year, Month, Date, Hour, Minute, Second)

ro.build.date= Write when you build the version

ro.build.user= Write your name

ro.build.host= Write your name

ro.cm.version= Write your ROM name here (Example: SlimROMs+, MiniCM10 etc)

ro.modversion= Write your ROM name here

persist.sys.themeId= Write your theme chooser theme you included in the /app folder

persist.sys.themePackageName= Write the package name of the theme you included in your ROM

ro.config.ringtone= Write your ROM's default ringtone

ro.config.notification_sound= Write your ROM's default notification sound

ro.config.alarm_alert= Write your ROM's basic Write your ROM's default alarm

3. Add tweaks to it. Search for tweaks in XDA, follow their guide on how to add it and do it.

We are done editing build.prop! It was not hard, was it? Lets continue onto modifying /Meta-Inf on the next post! :)
