    Unifi Lite-6

    Install OpenWRT

    Through ssh, normally the device get an ip through dhcp

    1. scp openwrt-21.02.5-ramips-mt7621-ubnt_unifi-6-lite-squashfs-sysupgrade.bin ubnt@192.168.10.151:/tmp
    2. Update environment:
    fw_setenv devmode TRUE
fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt"
fw_setenv bootcmd "run boot_openwrt"
    1. Check everything is set: fw_printenv
    2. Check the mtd partition number for bs / kernel0 / kernel1 cat /proc/mtd
    3. Set the bootselect flag to boot from kernel0 dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
    4. 4 minutes flashing dd if=/tmp/openwrt-21.02.5-ramips-mt7621-ubnt_unifi-6-lite-squashfs-sysupgrade.bin of=/dev/mtdblock6 dd if=/tmp/openwrt-21.02.5-ramips-mt7621-ubnt_unifi-6-lite-squashfs-sysupgrade.bin of=/dev/mtdblock7
    5. reboot took 3 minutes until having a solid blue line
    6. connect the ap directly to the computer since it runs a DHCP server and distribute an ip by default you need to switch as a dhcp client

    Note: default user ubnt, default password ubnt

    1. push reset during 20sec+, wait blinking state (blue, white, black, blue, white etc.)
    2. ip address add 192.168.1.25/24 dev enp0s31f6 && ip route add default via 192.168.1.20
    3. tftp
    4. In case the ip is not 192.168.1.20, you can find it by looking with tcpdump -i enp0s31f6 arp
    connect 192.168.1.20
