Unifi UAP-PRO installation

Installing and Using OpenWrt
1

Hi there,
I have an old UAP-PRO or AP-PRO. That I am having trouble installing the factory openwrt firmware on.

I have followed the instructions on https://openwrt.org/toh/ubiquiti/unifi_ap_pro

  1. Device get IP address from DHCP. If no DHCP, device will default to 192.168.1.20
  2. Login inside the AP with ssh ubnt@ip_address (password ubnt)
  3. Download factory.bin to /tmp
  4. Rename the firmware image to fwupdate.bin
  5. Use the Ubiquiti fwupgrade utils to reflash it:
    fwupdate.real -m fwupdate.bin

I can SSH into the device on the default IP. I can upload the factory.bin to the /tmp folder through winSCP.

I have the filename changed to fwupdate.bin according to the instructions but I keep getting the following error message through the SSH terminal when trying to flash to the new firmware.

UBNT-BZ.v4.3.28# fwupdate.real -m fwupdate.bin
Couldn't open image file: fwupdate.bin!

Any help would be appreciated.
Thanks!

After logging in with ssh you'll want to make /tmp your default directory:
cd /tmp
then make sure the file exists:
ls -l
rename if necessary
mv <OLD_FILE_NAME> <NEW_FILE_NAME>

and / or specify the full path to the file when doing the update:
fwupdate.real -m /tmp/fwupdate.bin
although later versions of fwupdate did not take the name it had to be /tmp/fwupdate.bin

Amazing. Thanks so much. That worked first try.
