After configuring the router and putting their respective addresses and saving, try to create a VPN and after that update the router, the thing is that when updating the router it has not stopped turning on and off and thus it has been almost 3 days without being able to start the configuration and also and tried with the netinstall but I have not been successful, any more method to recover the router?
Hi have you tried using the Backup boot loader to see if you can access the router and role back
Usually, you can do this by pressing the reset button for 3 seconds +/-
This is me assuming that there is an issue with the main bootloader after the update
