The rest of the process remains unchanged, so once the downgrade is successful you can move to **Step 2**.
Step 2: Copy the AREDN |trade| firmware to the device
Before you can install AREDN |trade| firmware on the device, you first need to put the AREDN |trade| image in the devices ``/tmp`` directory. Note that each 802.11ac model will have a *different* AREDN |trade| image name, as opposed to past releases where one AREDN |trade| image supported multiple models. Be sure to download the correct firmware image from the AREDN |trade| download site. On your computer, open a terminal session (“CMD” in windows). Copy the firmware to the device using the scp command with the username and password you created in **Step 1**.

If you see an error “Remote host identification has changed” you can try the following:
::
ssh -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa -oUserKnownHostsFile=/dev/null -oStrictHostKeyChecking=no admin@192.168.1.20
You will be asked for the password created in **Step 1** (for example, admin!23) and once entered you will be logged into the device and shown the shell prompt.
To install the AREDN |trade| firmware you first need to create a program to do this. Ubiquiti devices expect signed firmware but AREDN |trade| is not signed, so we need to bypass the checking process. To do this type or copy/paste the following two commands:
