After trying with the other 2 and that it will not work, probe with the kernel one and the Failsafe mode (recovery mode) was activated, the router when starting it turns on all its lights, then the power light flashes for a couple of seconds and then they remain All off but through putty I could verify that it was still on through 192.168.1.1 only that it no longer generates DHCP or has WAN connectivity, that is, it is in a very basic mode of operation.

I think that the problem can be solved by sending a command to download and overwrite the current version of the firmware, but since it does not have WAN connectivity, it does not have access to the internet and the download is not possible with the basic command, it would have to use the advanced version that implies download the file to the pc and configure with the appropriate commands, the server so that the router can download and overwrite from the pc instead of doing it from the internet, that part of the process is very advanced for me and I don't know how to complete it.

In the attached images you can check that the ram in the router is more than enough, and that in the state it is, it gives an error when executing the commands "firstboot", "mount_root" and "/ etc / config"

I hope someone can give me some advice or solution and I thank you in advance for your valuable input.
