After many many successful firmware updates on my RT-AC68U I've ran into my first major problem. After updating to 386.3 I was given a prompt on my browser to manually reboot the router and so I did. This was strange to me as it's the first time I've ever seen such a thing. Now the router keeps rebooting every minute or so and I'm unable to access its webpage. I've tried Rescue Mode quite a few times but the Firmware Restoration software keeps saying, "The wireless router is not in rescue mode." The router is in rescue mode as the power light is slowly blinking. I've also reset NVRAM. I'm at a loss so any help is greatly appreciated.
