msm8909+android5.1.1 Modifying model number (phone model)

/system/build.prop is a property file in the Android system. Prop files are important, documenting the system settings and changes, similar to files in/etc. How is this file generated?

build/tools/buildinfo.sh scripts are specifically used to generate Build.prop files

The Build.prop file is generated in Build/core/makefile using the build/tools/buildinfo.sh script,

and append the default System.prop of the system and the settings in the custom System.prop to the Build.prop file.

There are also some device-related configurations appended to Build.prop

We need to modify settings--->about phone--->buildnumber, which file needs to be modified, refer to the link http://blog.csdn.net/loongembedded/article/ details/49996253

(2) Build_number definition

The BUILD\SCM_SCRIPTS\PROJECTA.MK is defined as follows
