Getting lost license key

We have a bunch of routerboards that use to have RouterOS on them but at some point were reflashed with non RouterOS firmware. These Routerboards were purchased with RouterOS originally.

Is there a way to provide the serial number and get the license key back so we can reflash them back to RouterOS?

Thanks

You should write to support, here in the forum there is not much help to provide with your problem :slight_smile:.

What were they flashed with? If they are true router boards they might be able to recover them, but as stated support is your best bet.
