Tried to update to latest firmware (3.0.0.4.388_24231) after seeing there was an update available, via phone app first then via WebGUI, would get to 100% and say update failed. Router still worked at this point.

I attempted to update in recovery mode following Asus guidance, it failed there too except router now bricked. Tried repeatedly and kept failing. I can get a successful recovery message trying to apply the version I tried to update from (3.0.0.4.384.10177) and the original release (3.0.0.4.384.9261) but I can’t communicate with the router, doesn’t recognise any ethernet connection. The front RGB light flashing red. It only recognises the router exists in recovery mode but that’s not usable.

Router is 3 years old so expect I’ll get no help from Asus and don’t really want hassle with customer service.

Any tips or succumb to getting a new router?

I found a thread for AX86 and saw references to older release notes suggesting to not update to earlier new versions straight away, but there was no warning in the release note for 3.0.0.4.388_24231. Pretty annoyed. I’m a networking noob and only updated because I was prompted in the app, and thought I should for general security purpose. I only went into the app to assign my PS5 as a game device to reduce my ping!

Any help greatly appreciated.

    I don’t own an Asus but I have recovered routers of other brands. It’s been years since I recovered a router so I haven’t kept up to date with the latest developments.

    I assume that the recovery process you tried was the Asus Rescue Mode. If not, it’s documented here.

    If that doesn’t work, many routers have a serial port that can be used to assist with the recovery. I found this post that lists the steps. It’s for a different Asus router but it will probably work on yours.

    As you’ll see, it’s quite involved and requires you to buy a special type of serial cable (called a TTL-level cable). The cable is readily available on Amazon from a number of places and is not that expensive. It’s certainly cheaper than buying a new router. You have to open the router to connect the cable to the serial port inside. Then follow the process to start a TFTP upload of firmware.

    Take a look, then decide if it’s something you are willing to try. You probably don’t have anything to lose other than a few $ for the serial cable.

    Good luck.
