Bricked!!! Asus AC-88u

I have what seems to be a bricked asus ac-88u router. It powers on and has a power led for about 3 seconds, then it goes to fast blinking and stays like that. I have tried WPS hold into recovery mode, and holding the reset button. I have even tried both buttons for the 30/30/30 reset.

My power adapter has been tested and is fine.

This issue happened after the latest official firmware update from ASUS. This is the second time that the router did this after a firmware update. The last time...
