I found out that the build.prop is reset at shutdown on my device. So i am changing it when its off, with twrp flashable zip. An other way is to make it via adb on the pc, but its with twrp too.
You can search for tutorials in interent like
- flashable build.prop
- change build.prop via adb in twrp mode
For me the flashable zip work fine.
