How did it get into this state ?

Netinstall device, I would think.

The router was functioning, but at some point, it stopped booting up. Netinstall doesn’t detect this router, and the 85X resistors have burnt out. This is the second MikroTik with such an issue.
What is the cause of their burnout?

If you already determined hw failure, what else do you think could cause the boot loop ?
Already checked psu ?

PSU new

Original Mikrotik PSU or something else ?
