Installing a new version of Android on your smartphone or tablet can bring new life to your device. It can provide you with the latest features, improve performance, and fix security vulnerabilities. This article aims to guide you in detail on how to install a new version of Android. We will cover everything from checking for updates to manually installing a custom ROM if there is no official update available for your device.
1. Understanding the basics
To install the latest version of Android, you can take different steps depending on whether your device supports over-the-air (OTA) updates or you need to install a custom ROM. OTA updates are the simplest method, but not always available for older devices. Custom ROM installation offers more control, but also involves more risk.
1.1 OTA update
Most Android devices receive updates over-the-air, which means they can be downloaded and installed directly from the Internet without the need for a computer. This method is the easiest and safest way to update your device, provided your manufacturer still supports it.
1.2 Custom ROM
If your device is old and no longer receives updates, a custom ROM is your best option. Custom ROM is a modified version of Android developed by third-party developers. Installing a custom ROM requires technical skills, including unlocking the bootloader, and is risky as it can potentially brick your device.
2. Preparing your device for the update
Before you begin updating your Android device, there are several preliminary steps you need to take to avoid data loss and ensure a smooth process.
2.1 Back up your data
If something goes wrong while updating your phone, it can lead to data loss. It is important to back up all important data, including contacts, photos, videos, and app data. Google provides a backup service that can automatically sync your data to the cloud.
Settings → System → Backup → Turn on Back up to Google Drive2.2 Charge your device
A halted update installation due to lack of power can seriously damage your Android system. Always make sure your device is at least 80% charged before starting the update process.
2.3 Free up space
Downloading and installing new updates usually requires a lot of storage space. You may need to delete unnecessary files or applications to free up storage space prematurely.
3. How to install OTA updates
3.1 Check for updates
Modern Android devices periodically check for updates and notify you when they are available. However, you can manually check for updates by going to Settings.
Settings → System → Advanced → System update → Check for update3.2 Download and install
If an update is available, you will see the option to download and install it. It is advisable to be connected to a stable Wi-Fi network during this process to avoid data charges and ensure stable downloads.
3.3 Follow the on-screen instructions
Once the update is downloaded, follow the on-screen instructions to install it. Your device will probably restart during the installation process, which may take a while.
4. Installing custom ROM
For those who are adventurous enough to install a custom ROM, here is how they can do so.
4.1 Unlock the bootloader
The bootloader is a program that launches the operating system interface. Unlocking it is the first step to installing a custom ROM. Keep in mind that this process often voids the warranty and can potentially damage your device.
4.1.1 Enable developer options
Before you can unlock your bootloader, you'll need to enable Developer Options.
Settings → About phone → Tap 'Build Number' seven times4.1.2 Enable OEM unlocking
Next, enable OEM unlocking:
Settings → System → Developer options → Enable 'OEM Unlocking'4.1.3 Unlock via Fastboot
You will need a computer to unlock the bootloader. This involves using the fastboot tool.
adb reboot bootloader fastboot oem unlock4.2 Install custom recovery
Installing a third-party ROM requires a custom recovery like TWRP (Team Win Recovery Project). The custom recovery environment allows you to backup, wipe your system, and install new ROMs. An example command to flash a custom recovery is:
fastboot flash recovery <recovery-image>.img4.3 Download compatible ROM
To avoid problems, make sure the ROM is built specifically for your device model. Popular options include LineageOS and Pixel Experience.
4.4 Install custom ROM
4.4.1 Boot into recovery mode
After installing custom recovery restart your device into recovery mode.
Usually involves pressing Volume Down + Power Button simultaneously4.4.2 Erase current system
Go to the 'Wipe' option in TWRP. Select 'Advanced Wipe', then choose 'Dalvik/ART Cache', 'System', 'Data' and 'Cache'. Swipe to wipe the selected partition.
4.4.3 Flash the ROM
Go back to the TWRP main menu, select 'Install', and navigate to the downloaded custom ROM zip file. Swipe to confirm flash.
4.4.4 Reboot the system
After the ROM installation is complete, go back to the main menu and select 'Reboot' → 'System'. The first boot may take a while, so be patient.
5. Post-installation steps
5.1 Verify the installation
Make sure everything works as expected. Check if the device is booting up correctly and if you see the new setup screen.
5.2 Restore data
If you chose to manually install using a custom ROM, restore your data from a previously created backup. Connect to the internet and let your apps sync to recover data.
6. Troubleshooting common problems
6.1 Boot loop
If your device is stuck in a boot loop, i.e. it is constantly rebooting, you may need to re-enter the recovery mode and wipe the data/cache again.
6.2 No service or network issues
Make sure your custom ROM supports the network bands of your device. Sometimes flashing the correct modem firmware can fix network related issues.
6.3 Battery drain
New updates may recalibrate battery life. Give it a few days to stabilize, but if it persists, you may consider switching to a more stable ROM build.
7. Conclusions
Updating to a new version of Android, whether via an OTA update or a custom ROM, can offer many benefits. While the method you choose depends on your technical experience and the device you use, both methods can be beneficial. OTA updates are faster and less risky, while custom ROMs offer more control and new features. Remember to follow precautions such as backing up data and making sure your device has enough battery life before starting the process. With these guidelines, you are now ready to successfully update your Android device.
