Can't conect via ssh, via html or via ftp, led is permanently red

During the last software update, during the reboot, the tension of my house went away, from that moment I can not connect with My Cloud, neither by ssh, nor by port 80, nor by ftp.
Before this happened, I had it all activated, and working on linux as a job, it connected me directly to nfs.
I have removed the hard drive and I see that the data I had is there, but I do not see the partition of Debian, so I think, that this is in a xip, either RAM or an E2PROM.
Anyone know how to re-dump the Debian image on that chip?

Thanks in advance.

There’s no firmware on a PROM. It’s all on HD.
