    --aslrdisable       This option will path kernel to disable aslr on all process. use this when you creating boot files.
    --ptracedisable     This option will path kernel to disable ptrace debugger method detection. use this when you creating boot files.
    --boot              this boot the device.
    --keyServer         use this option to downgrade when the keys server is in problem. use ex: --downgrade 14.8 --keyServer
    --dont-restore      this will avoid the restore using futurerestore, this can be used if you wanted only create the boot files, use ex: --downgrade 14.8 --dont-restore
