Hi all,

Just got a new TM-AC1900 a few days ago and new to all of this. I have been stuck with this problem for a few days now.

Problem: I was in the process of flashing my TM-AC1900 to Asus RT-AC68U firmware when it stopped. When I next powered it up, there were solid lights on WAN and all four LAN ports. I have been able to press reset while it boots, however LAN ports are not working (although they light up). I have tried all combinations of pressing WPS, Reset buttons etc to no avail.

I purchased a serial cable and have been able to interact with the unit through that. Looks like firmware is not loading and boot loops.

I am able to hit Ctrl+C during boot to get into CFE. I have tried nvram reset, nvram commit and resetting ifconfig, however it looks like TFTP server (LAN ports) are not opening. I have tried to ping 192.168.1.1 and have setup static ip successfully on numerous laptops. Also tried snooping on ports, however no activity.

Is there anything I can do? or is this completely bricked? Any help would be greatly appreciated. I will post logs

Thanks a lot :)
