Installation
---
1. Power device using a PoE injector or switch
2. Connect via Ethernet to the device with static IP 192.168.1.2
3. SSH into the device with password: ubnt
$ ssh ubnt@192.168.1.20
4. Unlock kernel partitions for writing
$ echo 5edfacbf > /proc/ubnthal/.uf
5. Confirm correct partitions
$ grep PARTNAME /sys/block/mmcblk0/mmcblk0p6/uevent
PARTNAME=kernel0
$ grep PARTNAME /sys/block/mmcblk0/mmcblk0p7/uevent
PARTNAME=kernel1
$ grep PARTNAME /sys/block/mmcblk0/mmcblk0p8/uevent
PARTNAME=bs
6. Set and confirm bootloader environment
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt"
$ fw_setenv bootcmd_real "run boot_openwrt"
$ fw_printenv
7. Copy sysupgrade image to /tmp/openwrt.bin via scp
8. Copy kernel and rootfs to mmcblk0p6 and mmcblk0p7, respectively
$ tar xf /tmp/openwrt.bin sysupgrade-ubnt_unifi-6-plus/kernel -O | dd of=/dev/mmcblk0p6
$ tar xf /tmp/openwrt.bin sysupgrade-ubnt_unifi-6-plus/root -O | dd of=/dev/mmcblk0p7
9. Ensure device boots from mmcblk0p6
$ echo -ne "\x00\x00\x00\x00\x2b\xe8\x4d\xa3" > /dev/mmcblk0p8
10. Reboot the device
$ reboot
