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.

Werkseinstellung: ca 7-10s Reset Knopf drücken (LED geht von grün auf hellgrün)
IP: 192.168.1.20
Login: ubnt
Passwort: ubnt

Via SSH von Originaler Firmware

 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-ar71xx-generic-ubnt-unifi-squashfs-factory.bin ubnt@192.168.1.20:/tmp/fwupdate.bin
4: on router:
        cd /tmp
        # to check firmware run, because syswrapper does not display errors.
        fwupdate.real fwupdate.bin -d -c
....
        syswrapper.sh upgrade2 &

Via TFTP

 TFTP Upgrade Process
 Very helpful in case your upgrade went wrong or your AP is not responding anymore. See TFTP Unbricking section below for more detailed 
 instructions on this process

Keep the reset button pressed while powering on AP
Once the LED ring is blinking green/orange, you can run the TFTP command.
In case you are on Windows, the command is:
tftp -i 192.168.1.20 put openwrt-ar71xx-generic-ubnt-unifi-squashfs-factory.bin
If this is succesful, you will see:
Transfer successful: 3342748 bytes in 2 second(s), 1671374 bytes/s
After this, just wait for about a minute for the AP to reboot and boot OpenWrt. The LED ring will show static green when ready.

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.
