someone knows how to edit the file build prop, I know I take it all in my responsibility for any brick ... I will not ask you any resolution after if my phone would go in brick.thanks
You need a rooted phone with an Amaze file manager for example. Open build.prop file, edit it and then save it. Now open build.prop properties and set permissions to r-w-r-r. That's it, restart device so the changes take effect.
