Aqara G2H enable telnet

[thankarezos]

I have chinese version of the Aqara g2h. I am trying to enable telnet but nothing happens, When i try to telnet 192.168.1.28 I get connection refused. I also tried to connect it to the aquara home app but it doesnt connect. only to the mija app. the firmware is 3.5.8. Also I have a CH340G usb module. if flashing like that is not possible to this version I would like somone to point me on a good guide on what should i solder where to flash it via hardware.
