if you check Yakjuxw build.prop (stock 4.0.2) it is same, only the device information is different..

EDIT: also if the build is not only ICL53F and it is icl53f.i9250#### then you have to add it to build.prop too..

UTC time text and other maybe not needed to edit because it should still update 4.0.2 if it has the system/etc/updatecmds folder ...?
