Wrong open telnet command

[Fox7ro7]

Hi everyone, trying to add Xiaomi Gateway 3

• Model: ZNDMWG02LM - lumi.gateway.mgl03 but I can't seem to enable telnet on the device (the token is correct) FW: 1.4.6_0040

Tried; {"id":0,"method":"enable_telnet_service", "params":[]} {"method":"set_ip_info","params":{"ssid":"\"\"","pswd":"123123 ; passwd -d admin ; echo enable > /sys/class/tty/tty/enable; telnetd"}}
