Now that you know why the error occurs, here are some step-by-step troubleshooting tips to fix firmware upgrade issues on your Android device.

6 Ways to Fix “Firmware Upgrade Encountered an Issue” on Android

1. Restart Your Device and Retry

The simplest first step is to restart your Android device and try upgrading the firmware again from the beginning.

  • Power off your device completely.
  • Wait 10-15 seconds, then power it back on.
  • Once restarted, initiate the firmware upgrade process again.

Restarting clears any temporary glitches that may have interfered with the firmware installation. This quick fix works surprisingly often.

2. Check Your Internet Connection

An unstable internet connection is one of the most common reasons for failed firmware upgrades.

Before installing firmware:

  • Disable mobile data and connect your device to a stable WiFi network.
  • Run a speed test to confirm your WiFi connection is strong.
  • If possible, move closer to your wireless router for a stronger signal.
  • Avoid public WiFi networks which tend to be unreliable.

This ensures your firmware download and installation isn’t interrupted.

3. Free Up Storage Space

Insufficient storage is another culprit for the “Firmware upgrade encountered an issue” error.

Here are some ways to clear storage before upgrading firmware:

  • Uninstall unused apps – Remove apps and games you no longer need.
  • Clear app cache and data – Wipe cached and temporary data for apps.
  • Delete downloads – Get rid of any large downloaded files.
  • Remove old backups – Your Android backups take up space.
  • Clear browser history/cache – Delete browsing history and temporary internet files.
  • Transfer media to cloud – Upload photos, videos, and music to cloud storage.

After freeing up space, you should have enough storage to install the firmware update smoothly.

4. Download Firmware Again

Corrupted or partial firmware downloads can also create upgrade issues. When you get the error message, delete any existing firmware files on your device storage.

Next, re-download the correct firmware for your Android model from the official source. Double check you have the full firmware package before trying to install again.

This ensures any firmware file errors are eliminated.
