Android System Update Failed to Install Error: Fix it Now!

Did the Android update fail to install? Here is the simple guide to fix Android system update failed to install.

Are you getting an Android update failed to install error message? Usually, this message appears when you try to upgrade your Android device to a new system. When the device fails to install the available update, this message may appear. In this guide, I will explain some troubleshooting tips to fix this problem and install system update smoothly.

System update installation fails if internet connection is poor. An Android OS update usually weighs around 500MB and goes up to 2GB or more. Internet is a must to download or install software update. Also, it is imperative that you have sufficient battery charge on your device. Smartphones are typically designed to refuse a system update when only less than 30 percent of the battery is available.

Also, if you have a rooted Android device, the system might have been corrupted in some way. This happens when the rooting process is done wrong. Some applications may refuse to work, and system updates will fail to install. The lack of storage on your Android device will also cause it to refuse to install the software update.

Top Ways to Fix Android Update Failed to Install

Here are the various fixes that you should try.

Check your internet connection

Check if the WiFi is disabled, which you are using to download the system update. If you have enough mobile data, you can use it instead. Despite this, downloading the update will be slow. Alternatively, you can connect to another WiFi network, if possible, to download the software update.

Get enough battery charge on your device

To download the system update, your Android device needs to charge at least 50% battery or more. You can set the device to charge and then update the system. Low power will not allow you to continue installing the system update. This is the case with every smartphone out there.

Free up storage space on your device

To update to a new system version, make sure that the device has enough free space. To check and free up storage, follow the steps below.

  1. go to the Settings > storage > empty space.

You will see how much space your device storage is taking up and how much is available.

Restart your Android device

Often times everything will be fine. I mean, the network is stable, your current system build has no bugs, and none of the other common technical issues. However, you end up encountering an Android system update failed to install error message. Try restarting your device.

  1. Press the power button On the phone.
  2. Select option Restart.
    Restart your Android device

Stop using a VPN

  1. Open the VPN app.
  2. Press the dedicated button to turn off the feature.
    Disable VPN on Android

Use the network-provided date and time

To avoid any hassles with installing a software update, you should always use the date and time provided by your network. You can enable the automatic time of your Android device. Here are the steps to do that.

  1. open the Settings app> go to System. Click on it.
  2. tap on date and time.
  3. Enable the option Use the available network time.
    Enable automatic time on your Android device

Install system update using ADB Sideload

You can get an OTA zip file, which consists of the latest system update. This should be available in the support section of the official website of the smartphone brand you are using. Otherwise, in the official community forum of users of the same smartphone, you may find someone sharing the compressed OTA file.

  1. Download OTA zip to your computer. [rename this file to something convenient]
  2. Activate flash tracking on your smartphone.
  3. Then install the file Android SDK Platform Tools.
  4. Move the OTA zip file to the same folder where you saved the SDK tools.
  5. Also, install custom USB drivers for your smartphone.
  6. Connect your computer and smartphone with a USB cable.
  7. Open Command Prompt by visiting the folder where you saved the platform tools.
  8. give the command
    adb reboot recovery
  9. Once in the recovery menu, scroll to the option Update application from ADB Using the volume keys of the smartphone. Select the option by pressing the Power button[do not long press].
  10. Now, in the command prompt, enter the following command.
    ad sideload otafilename.zip
  11. otafilename is a placeholder that you have to change to the actual file name, which you renamed in this first step.
  12. Let the installation finish. Then scroll to the option Reboot Option using the volume keys. Press the power button to confirm restart.

Now, you have successfully installed the system update.

Use safe mode to install software update

When safe mode is enabled, your device will boot without third-party apps installed on the device. Also, you can install system updates smoothly without facing any error messages.

  1. Press the power button
  2. When you see the following screen, long press on the Power off option.
  3. A small pop-up will appear asking you to confirm that the device is running without third-party apps.
  4. tap on yes moving forward.
    Restart Android for Safe Boot

To go back to default, all you have to do is reboot again from safe mode.

Go back to Stock ROM on Android device

Since Android is an open source operating system, users try to experiment by installing a custom ROM. This is a third party ROM that replaces the stock ROM. Technically, the original ROM should not be tampered with. It has often been noticed that when switching to custom ROMs, users have problems installing system updates from the original equipment manufacturer.

Make sure you know how to go back to the stock firmware from the original equipment manufacturer. To reinstall the default firmware on your Android phone, you can refer to the same forums from which you picked up the custom ROM and the instructions for flashing it on your device. I am sure you will find some information.
