I highly recommend NOT to flash this. It installs a modified version of SafeStrap 3.72 which cannot be uninstalled. Installing corresponding SafeStrap Apk does not help since it does not recognize modified install. It basically hooks bevor booting Rom/recovery and should display a bootmenu allowing to choose between normal boot and recovery for 10 sec. Which does not work on s8 at least, resulting in showing Samsung splash screen for 10 seconds. disabling Monitor mode does NOT uninstall it, you will have to reflash stock using odin. Search this thread for more info.
