Unfortunately, a Linksys E8450 of mine has succumbed to the OKOD (OpenWRT Kiss of Death) (in case you are unfamiliar). From what I understand, it should be recoverable from it's current effectively bricked state. I've tried going through the process, but I haven't had too much luck, and I'm somewhat stuck at the moment, so I would appreciate some guidance. There's two potential objectives that I am hoping to acheive: the first, and primary, objective is to simply recover the router from its currently bricked state so that it can be used like normal, and secondly, if possible, recover the data, and configuration that was on it.

I have tried following this guide, but I'm not sure what I am supposed to do at the end. I completed the last step, but the router still isn't able to boot on its own. If I run boot from the U-Boot console, it appears to be able to boot into the OpenWRT CLI, but if I then reboot from that CLI, it shows the following error:

That same error is what shows when I watch the serial output of the router while it boots from the power switch.
