I’m trying to isntall Openwrt to Mikrotik hAP ac², to use tvheadend, but im hitting a wall. The kernel installs okay, I can boot luci web, everything working, but when I try to sysupgrade, as I’m supposed, yhe router bricks itself, and must start over again. I tested installing the sysupgrade via web, and telnet.
Go to /system routerboard. Running print likely shows upgrade version lower than current. Next execute upgrade … it will actually downgrade routerboot to the version available from currently running ROS.
