This will try today.
I flashed asus fw while in recovery mode , then flashed merlin fw afterwards.snbforum is the best resource. Try flashing Merlin fw via recovery. it could be something is physically damaged on the board, best way to diagnose a router is to use a ttl uart to usb module and read the serial output.
asuswrt-Merlin is the best most stable third party firmware for ASUS routers https://www.asuswrt-merlin.net/

no go either,
for that router needs to be in recovery mode. i did put in reocovery mode, installed DD-wrt , even then i could not see wifi. so kept it aside. yday took the router to fiddle with, it did not got dd-wrt interface, nor will it go to recovery mode.There is a Asus Flash Tool which you can use to restore a corrupted flash. Maybe that will help
Sad. The Asus routers are very solid in my experience. I have an old WL-520GU lying around, that works well. It should be more than 10 years old nowdid not got dd-wrt interface, nor will it go to recovery mode.
