HI, only short. Every of the Custom Rom Developer know some of the etc/init.d Tweak Scripts which makes the system faster and better. for example but one user in my community recognised is that they don't work anymore. If you look with Root Explorer into the files nothing have been changed. this is strange because the Optimus Speed faces also big problems when you change something in the build.prop or anywhere else. It looses root permission and other stuff. so the question is here, does it happen also on other devices ( please can somebody confirm and look which scripts are used and if they change the values in that specific files ) and tries MIUI to prevent Rom Developers from their work and want to have only clean versions ??????
