how do you use this command, can you explain further more, if you don't mind..?

Use uart cable via box interfect

You cannot write it just in command prompt. To talk to phone you need to open link to it, at least with terminal emulation application to COM port that phone add and you see in device manager. The most common known app to handle your command is realterm ... so try it.

how do i use this command in realterm, there are many option,
will you please explain more, thanks..

please be more specific, port speed, etc

I 'm used Putty terminal, on specific com port, but not response from phone. cable is from z3x used for serial frp remove
