ASUS RT-AC87U bricked and not enter into rescue mode

[ru13en]

Hi guys, my asus router gone nuts while i was out of home.
No wireless, no ethernet connection...
It has the latest original FW (3.0.0.4 380.7378) updated few days before.
Previous FW was the (3.0.0.4 380.4180).
Now, it stays like this:

(Power led connected with low light and wan port red at low light or blue if lan cable connected)
If i connect an lan cable to port 1, led 1 don't turn on.
Led of other ports turn on if i connect a lan cable to them.
I tried everything that i saw in this thread.

Reset button + power on way.
Wps button + power on way.
DHCP or static IP configuration (192.168.1.x + gateway 192.168.1.1).
Put it with no power during the night and try again.

However i wasn't able to put it in rescue mode (power led is always in the same way).

Connected to PC, i have no ping (timout or unreached destination) and no mini CFE on web browser.

The only hypothesis that is missing is to open the router and connect it via serial.

There is any other way to put it on rescue mode?
It seems that some kind of configuration on CFE boot it's stuck it with no tftp boot up.

Thanks for any suggestion.

Open it and connect serial cable and check the info, otherwise RMA it.

Hi friend, sorry for revive this old thread, but i have the same problem with my router. Power off during factory reset and now show the same low lights.

Finally you can repair the router witouth a RMA?

Thanks for your help and sorry for my english, this is the only one thread about this problem i found.

maybe in rescue mode, try one after the other
either power off and on again
press WPS while power on
press reset button
download restauration tool, install as admin, set PC-LAN IP to 192.168.1.10, connect PC to router-LAN, start program as admin, choose firmware and load it to router.

I can't enter in rescue mode, in any form, with power on while wps button is pressed or reset button pressed while power on. The lights are the same and no ping to 192.168.1.1.
