lost software license because of OpenWRT test

Hello there I’ve got a new device hAP mini and I’ve tried OpenWRT but I want to return to RouterOS. I’ve lost my license key because I don’t save it before installing OpenWRT, was my fault.

What I could do?

Hi,

try to write MT support…

Simply after the successfully restore of the RouterOS,
register here:
https://mikrotik.com/client
after that go to
https://mikrotik.com/client/keyRequest
and insert your Serial Number and Software ID,
you give back already existant licence to put back on your RouterBOARD
