Mikrotik hAP ac2 help needed

If anyone could help with the issue I'm facing I would greatly appreciate it.

I am trying to install Openwrt on a Mikrotik hAP ac2.

Followed all the guides and Youtube videos I could find.

routerOS version before flash: 6.48.6

I flash the kernel using tftp netboot

I then login to the luci interface via 192.168.1.1

I then went to System > Backup/flash firmware and flashed the sysupgrade file that was download

After the image has flashed I get no IP from the router. I've tried all the available versions on OpenWrt's site
