Finding The Product Key

Hello :smiley:
I am trying to upgrade my herelink device
I am stuck at the product key screen
I cant find any product key I see the S/N but it doesnt fit
Is there a way to find it? If not is there a way to downgrade the firmware in order to get it to work again?

Thank you

You need to contact your reseller from which you have bought herelink. He will provide you with serial number you need to upgrade.

Well I am stuck now
He says that there was a note on the nylon that covered the box which had a the code but I guess I
throw that away
Is there a way to reinstall the older version?

Your dealer can contact cubepilot and they should be able to get the key. Just give them your SN.
