Firmware Flashen

Der UniFi AP ist ein Router der in der originalen Firmware keine eigene Konfigurations-Oberfläche besitzt.

Es gibt unterschiedliche Geräteversionen, wodurch die Firmware anders aufgespielt wird. Der Router besitzt einen Reset-Knopf, mit dem das Gerät in den Urzustand gesetzt werden kann. In diesem Zustand besitzt der router folgende IP:

IP: 192.168.1.20

Via SSH von Originaler Firmware

lede-ar71xx-generic-ubnt-unifi-squashfs-factory.bin

1. connect router on LAN 2. ssh ubnt@192.168.1.20

  password "ubnt"

3. remote copy factory image to router

  on PC:
   scp lede-ramips-mt7621-ubnt-erx-initramfs-factory.tar ubnt@192.168.1.1:/tmp/

4: on router:

       cd /tmp
       add system image lede-ramips-mt7621-ubnt-erx-initramfs-factory.tar
       show system image
       reboots

Device get IP address from DHCP (without DHCP the UniFi AP's default to 192.168.1.20) Login inside the AP with ssh ubnt@ip_address (password ubnt) Find the image like “openwrt-ar71xx-ubnt-unifi-*-factory.bin” on openwrt binary repository and download inside /tmp. Rename the image to fwupdate.bin Use the Ubiquiti fwupdate.real script to reflash it: fwupdate.real -m openwrt-ar71xx-generic-ubnt-unifi-squashfs-factory.bin -d Later 3.xx firmware versions fail to upgrade using the above and brick so use instead. If brick reset device with 20-sec-press way with connected lan-cable - after it tftp start work.
