SCV2040 stuck in initial configuration loop?

I sucessfully (I hope so) reset a decomissioned SCV2040 to factory defaults, set a new password and a know IP address. Starting the Dell Storage Manager, it tells me the SCV needs an initial configuration, which is totally normal for a "new" unit.

After going through the steps of that initial config, I click on "continue" and the whole process jumps back to the beginning and that loop continues eternally.

I suspect the problem is a pretty old SCOS version of 7.1.4 and the oldest DSM I tried is from 2016. I also tried 2022 version with the same effect...

Stupid part is that the software update does not work either, maybe because it's too old or I'm missing some IP parameters. Is there a way to update the system offline? Or does anyone know how to get out of this loop?
