Can you please decode this boot loop error message? Is it about firmware corruption or hardware failure of ram/internal flash?

Hi @betonel,

Welcome to the Zyxel community!

Since this model has been EOL for a while, you could reference this topic to recover your switch.

The attachment is the BIN and ROM file of GS2200-24 for the recovery.
