It happened the very first time i ran the tool. The 2nd time, I reflashed the ROM file, and my phone booted up again, then I ran the tool, then still the same. The third time, I reflashed just boot.img to reduce the waiting, then manually type the commands, and it works.Perhaps you use the tool too many times without read my instructions, it's gonna mess up your system cmdline file then your device will never boot.
Not sure why but after "type cmdline_add >> cmdline" command, the cmdline contents is like this. Maybe my PC is infected with viruses or something?
