Adding OpenWrt support for Mikrotik hAP ac 3 [RBD53iG-5HacD2Hn]

First of all, you are in the wrong topic.

https://forum.openwrt.org/t/adding-support-for-mikrotik-hap-ac3-lte6-kit-d53gr-5hacd2hnd/

Second, you loaded the wrong image, with the wrong method. The Hap AC3 is not completely the same as at Hap AC3 LTE6 kit. You need to recover to ROS version 6 via netboot, and then start again based on the commit message of the LTE6 kit and NOT the one you mentioned.
