    GT-AC5300 bricked router - No keyboard input over serial

    Which chip? The unit is no longer under warranty so Asus can't help unless I pay for it.

    GT-AC5300 bricked router - No keyboard input over serial

    I am not using the adapter with RPi. I had it connected directly... see the pic attached. I used this this page as reference. https://www.snbforums.com/threads/unbrick-asus-rt-ac68u-router-over-serial-connection-using-a-raspberry-pi.56567/ Because it didn't work on RPi, I got an USB to TTL...

    GT-AC5300 bricked router - No keyboard input over serial

    I initially tried with RPi and when that didn't work, I got a USB to serial adapter that I've linked in my original post from Amazon and connected to my pc. I see the same exact behavior in both cases. I left the 3.3v VCC open. Didn't connect any wires to it. Only GND, TX and RX pins are connected.

    GT-AC5300 bricked router - No keyboard input over serial

    I've spent countless hours reading the threads here and other places trying to recover my Asus ROG Rapture GT-AC5300. Router is in boot loop... can't break cfe, I believe that's because my keyboard entries aren't getting passed over serial connection. This is the cable I used to make the...
