Using 2.9.51 and tried to upgrade by placing the 4.16 in the File area. On reboot nothing is happening.
1) is it the .ink? Yes, it is.
2) is my current 2.9.51 a paid for license? Yes, it is.
I am using Winbox 2.2.18
One of my boards is the WRAP-1E and the other is a RB153, both are not upgrading.
Is there are restriction based on current version to latest version?
Is there a payment requirement I am unaware of?
Is there a step I am missing due to version revisions from 2.9.51 to 4.16?
Is it necessary to upgrade as the boards are both performing properly?
Also, Lost two boards due and still have the 2.9.51 licenses on the Flash Cards. Can these be reassigned?
