How to install OpenWrt to Newifi D1 router?

Hi, when I search "newifi d1" on this forum. There are 7 results and people have been using openwrt on this device. But I can not find any installation method on this forum at all. The device page has installation method "unknown". Can anyone guide me how I can install openwrt on this router? Thanks a lot.

Thanks a lot for the reply. That talks about D2 instead of D1. I found some Chinese articles which talk about flashing breed bootloader first. Maybe I will try that way. Cheers.
