Don't worry; this comprehensive guide will walk you through troubleshooting steps to resolve this issue and get your device updated successfully.

What Does Android Update Failed Error 407 Mean?
Error 407 typically indicates a problem with authentication or authorization during the Android update process. Your device can't verify its identity with Google's servers, preventing the download and installation of the update. This isn't necessarily a problem with your device itself, but rather a communication issue between your phone and Google's servers.
Why Does Android Update Failed Error 407 Occur?
Several factors can trigger this error:
- Network Connectivity Issues: A weak, unstable, or intermittent internet connection is a primary culprit. Error 407 often arises when the download is interrupted or the connection drops during the update process.
- Incorrect Date and Time Settings: Inaccurate date and time settings on your device can disrupt communication with Google's servers, leading to authentication failures.
- Proxy Server Problems: If you're using a proxy server, incorrect configurations or server issues can interfere with the update.
- Software Glitches: Sometimes, temporary software glitches on your device or Google's servers can cause authentication problems.
- Corrupted System Files: Damaged system files can also prevent successful updates.
- Insufficient Storage Space: Ensure you have enough free space on your device to accommodate the update.
How to Fix Android Update Failed Error 407
Let's tackle the most common solutions:
1. Check Your Internet Connection
- Strong and Stable Connection: Ensure you have a strong Wi-Fi connection. Avoid using mobile data, as it can be unreliable during large downloads. Try restarting your router or modem if necessary.
- Sufficient Bandwidth: Downloading a large Android update requires ample bandwidth. Avoid using other bandwidth-intensive applications while updating.
2. Verify Date and Time Settings
- Accurate Settings: Go to your device's settings and verify that the date and time are correct. Enable "Automatic date and time" to ensure synchronization with network time servers.
3. Disable Proxy Settings (If Applicable)
- Temporary Disable: If you use a proxy server, temporarily disable it to see if it resolves the error. Once the update is complete, you can re-enable it.
4. Restart Your Device
- Simple Reboot: A simple restart can often resolve temporary software glitches that might be causing the problem.
5. Clear Cache Partition
- Detailed Steps: This step involves deleting temporary files that could be interfering with the update. The exact steps vary slightly depending on your Android device's manufacturer and model, but generally involve booting into recovery mode and selecting "Wipe cache partition." Consult your device's manual or online resources for specific instructions.
6. Check Storage Space
- Free Up Space: Ensure you have ample free storage space on your device before attempting the update again. Delete unnecessary apps, photos, or videos to create more space.
7. Try Updating Through a Different Network
- Alternative Connection: If you're using Wi-Fi, try switching to mobile data (if available) or vice versa. This can help determine if the issue is network-related.
8. Factory Reset (Last Resort)
- Data Backup: Before proceeding, back up all your important data to prevent data loss. A factory reset will erase all data on your device.
- Warning: This should be your last resort. After the factory reset, your device will be restored to its factory settings, and you will need to restore your data from a backup.
Prevent Future Android Update Errors
- Regular Maintenance: Regularly clear your device's cache partition and ensure you have sufficient storage space.
- Stable Internet: Always ensure a strong and stable internet connection during updates.
- Device Compatibility: Verify that your device is compatible with the latest Android version before attempting the update.
By systematically following these troubleshooting steps, you should be able to resolve the Android update failed error 407 and successfully update your device. Remember to always back up your data before undertaking any major troubleshooting steps. If the problem persists after trying these solutions, contact your device manufacturer or your mobile carrier for further assistance.
