AC66U - Can't install Merlin firmware

[meh123]

Hi, I have downloaded Merlin and John's fork and unfortunately when trying to swap to either of these firmware, I get the below message. I want to use OpenVPN and from what I read John's fork has nice optimisations that can increase the bandwidth. Is there anything I can do? Is anyone else encountering the same issue?

There is no Merlin support for RT-AC66U anymore, how could you have tried with his firmware?

Do you really have an RT-AC66U or is it an RT-aC66U_B1, if later you have to use firmware for 68U!
And Johns fork needs to be loaded with mini-web or Asus restauration tool.

Hey! Thanks for reply. I downloaded the legacy version of Merlin (380.7). I checked on the router itself and the label says "RT-AC66U". How would I use mini-web tool?
