LAN seem to be working, at least it's getting configured with an IP of 192.168.1.1. Make sure you erase the nvram, it might contain invalid settings from the DD-WRT image that's currently installed.

In any case, you don't need JTAG since CFE is working.
 
With jtag 1.nvram clear, 2.nvram commit, 3.reboot
Try but nothing. My PC lan setting 192.168.1.10 mask:255.255.255.0. When try to ping 192.168.1.1 return me destination host unreachable.
when put a cable in all 4 port no lan port led light.
Is it possible hardware problem?

Could be. Make sure your PC doesn't have multiple network interfaces (i.e. disable wifi if it has that enabled).
 
All interface was disabled except lan with IP 192.168.1.10. No ping. Is it possible to reflash router via com port, without working lan?

I don't know, I never tried. But if the ports don't work in the CFE, they're quite likely to not work in the firmware either.
 
After 2 months of experiment my router is alive :) but no 2.4Ghz wifi - is it possible to fix it with jtag command or new firmware? Can someone give me a link for latest version of cfe.bin for Asus RT-AC5300
Thanks
