# SOFTWARE

You can upgrade the software in **two ways**:

## **Using the “OTA UPDATE” Tab**

{% stepper %}
{% step %}

### **Step 1:**

Ensure that you can access the Lynx web settings at:\
👉 192.168.144.240:8000 or \<Lynx\_IP>:8000
{% endstep %}

{% step %}

### Step 2:

Click on the OTA UPDATE tab.
{% endstep %}

{% step %}

### Step 3:

Select **Manual Update**.
{% endstep %}

{% step %}

### Step 4:

Click **Browse** and select the **.zip** firmware file.

> 💡 **Tip:**\
> Make sure the folder path does **not contain spaces** or **special characters** in its name.

Wait **2–3 minutes** for the update process to complete.\
Once finished, **Lynx will automatically restart**.

After the restart:

* **Close** the current browser tab and **reopen** it.
* ⚠️ **Do not refresh** the current page during the upgrade process—doing so may cause the Lynx to repeatedly attempt firmware upgrades.
  {% endstep %}
