I can't connect Xiaomi Gateway (lumi.gateway.v3) to HA

I just get my Xiamomi Gateway, it now has the newest firmware, I think this is why I can’t succfully add it to HA, my firmware verson is 1.4.1_170.0158.
I have seen the instruction about open up the gateway and open port 9898, I think that is way beyond my capability, here is the instruction video:

Is there any way I can make this device work with HA without open up the device?
As far as I know, there is an older Xiaomi Gateway version like v1 that should work with HA without problem, but I can’t find a place to buy the older one.
Hope I can find some solution that I can try before I give up and put the device into its coffin.
Thanks.
