I have a HAP ac2 that looks great and I'd like to run Open-WRT on it. i'm following the instructions here:https://openwrt.org/toh/mikrotik/common. My device (as it arrived) is running RouterOS v6.46.5(stable)
The issue is the warning to downgrade to version v6.45.8 looking at the link to Mikrotik's firmware, they no longer offer the older firmware version (and I have no way to know if my device would run it anyway) I can add photos of the PCB if this helps.
So, how to get a copy of the older RouterOS firmware?
