Cannot load Stock Firmware

[TonyK132]

I have an AC68U with Merlin 384.19 inside. I want to put stock back in. But when I do Update from Admin page, it says I cannot do that. What do I need to do?

Are you sure you're using the correct firmware, e.g. not the RT-AX68U or RT-AC86U?

How about trying an intermediate version first like 3.0.0.4.386.40558.

You might have to flash it in Rescue Mode.
