This guide will show you how to manually install a firmware of your choice. This firmware can be one of the builds published by Onion or a custom firmware image.
Step 1: Downloading the Firmware Image
Firmware images for the Omega2 family can be found on the Onion repo: http://repo.onioniot.com/omega2/images/
Let’s begin by downloading the latest firmware image from the Onion repo. This repo is where we keep all the builds of the various Onion Firmware.
On your Omega, start by changing directories to
Now we’re going to need the link address of the firmware we want to download. Right click on the link, and select the
copy link address option:
Note: There are two versions of the firmware; one for the Omega2, and one for the Omega2+. You’ll need to make sure you’re copying the link to the correct firmware.
- Omega2 firmwares start with “omega2-…”
- Omega2+ firmwares start with “omega2p-…”
- Omega2 Pro firmwares start with “omega2pro-…”
Next, enter the following into your terminal:
wget <LINK ADDRESS>
<LINK ADDRESS> is the link you copied from the repo. Your command-line should look something like this:
root@Omega-2757:/tmp# wget http://repo.onioniot.com/omega2/images/omega2p-v0.3.2-b218.bin
Once you’ve verified that link is to the correct binary, hit Enter and your firmware will begin downloading.

Take note of the name of the firmware you just downloaded for the next step. In this example, the name is
Alternative Step 1: Downloading Firmware onto a USB Storage Device
If your Omega no longer has enough room to download the Firmware, you can download the firmware onto a USB Storage Device and work from that USB’s directory on your Omega.

Step 2: Upgrading your Omega to the Downloaded Firmware
The command to upgrade your Omega’s firmware is
sysupgrade. You can run the following command to upgrade your firmware:
sysupgrade <FIRMWARE FILE NAME>
From the above example, the command would look like:
and you’ll see output similar to the following upon entering the command:
root@Omega-2757:/tmp# sysupgrade omega2p-v0.3.2-b218.bin Saving config files... killall: watchdog: no process killed Sending TERM to remaining processes ... uhttpd device-client avahi-daemon onion-helper udhcpc mountd ntpd shellinaboxd udhcpc dnsmasq ubusd logd rpcd netifd odhcpd crond Sending KILL to remaining processes ...
