Software Update Error Code 407: Why It Happens & How to Fix It

When you try to install a system or firmware update on your device and get error code 407, it can be frustrating. This issue occurs across different platforms (Android phones, tablets, computers) and shows your device failed to download or install the update. In this post, you’ll learn what error 407 means, what causes it, and how to fix it in practical steps.

What Does Error Code 407 Mean?

In many contexts, error code 407 is a kind of “access denied” or “authentication required” error. For example:

On Microsoft Patch systems, 407 represents patch download failure due to authorization or proxy issues. (ManageEngine)
On Android/Samsung devices, users report update attempts failing repeatedly with “Error 407”. (Verizon Community)

In short: your device tried to connect to the update server, but could not download or install the update because of a network, server, or device-side restriction.

Common Causes of Software Update Error Code 407

Here are typical reasons why error 407 happens:

Network/Proxy issues: A proxy server or corporate network may block or require authentication for update downloads. (ManageEngine)
Server access denied: The update server may require credentials or the request is blocked.
Device storage/permissions problem: The device might lack space, or update components can’t be accessed.
Firmware or update loop bug: Especially reported on some Android phones with specific carriers. (Reddit)
Corrupted update cache or partial download: Download interrupted, leading to loop or repeated failure.
External apps interfering: VPN, custom ROM, carrier lock or proxy list could block official update path.

How to Fix Error Code 407: Step-by-Step

Step 1: Check Your Internet Connection

Connect to a stable Wi-Fi network (avoid mobile data).
Ensure no VPN or proxy server is enabled (disable temporarily).
If on corporate network, try home network to test.

Step 2: Free Up Storage & Clear Cache

Go to Settings → Storage, free at least 1–2 GB space.
On Android: Settings → Apps → System Update → Clear Cache & Clear Data (if allowed).
Reboot device and attempt update again.

Step 3: Restart and Retry the Update

Simply reboot your device and then go to Settings → System Update → Check Now.
On Samsung: some users found repeating this helped. (Verizon Community)

Step 4: Manual Update / Firmware File (if available)

For Android devices: Download the correct firmware for your model from official site.
Boot into Recovery Mode, install update manually (commonly for advanced users).
Always back up data before manual update.

Step 5: Remove Proxy/Disable VPN/Carrier Restrictions

Go to Settings → Network & Internet → VPN / Proxy, disable them.
If under carrier update restrictions, contact support.

Step 6: Factory Reset (Last Resort)

If the update still fails, you may backup your data and perform a factory reset.
After reset, retry the update before reinstalling all apps.

Best Practices to Avoid Error Code 407 in Future

Always update your system when it becomes available (reduce backlog).
Ensure you’re using official firmware or update path — avoid custom ROMs/modified files.
Keep your device’s storage healthy (not full).
Use official network or disable interfering proxies/VPNs before updating.
Enable auto-download over Wi-Fi only when on trusted network.
