I have not gotten my device rooted yet, but I was wondering if the command setprop <key> <value> required a reboot for the changes to take place. In the past I have edited the build.prop file, but the the device required a reboot for the changes to take effect.
I need to change the build information (ro.build.id,ro.build.version...etc) and have them be reflected in the system properties instantly. The System Properties gets its information from the build.prop file upon a boot, therefore any changes to the build.prop file are not reflected until a reboot.
Does setprop change the build.prop file, or does it actually change the current property of the system, and if so, will this change be reflected without a reboot? This is aim of the project. Any help is appreciated.
As a corollary, if the system properties are loaded from the build.prop file upon boot, where are these properties actually stored?
