Important Notes:

• Modifying your phone’s software can be risky and potentially damage your device. Proceed with caution and at your own risk.
• Always back up your data before attempting any updates or repairs.
• Check your phone’s current software version: Go to Settings > About phone > Software version.

Official Update Options:

1. Check for Automatic Updates:
   • Go to Settings > Software Update.
   • If an update to Android 7.0 is available, you’ll see a notification and can download and install it directly.
2. Contact Oppo Support:
   • If your phone isn’t showing an update, you can reach out to Oppo support for assistance: https://www.oppo.com/
   • They can check if your device is eligible for an update and provide further instructions.

Repairing to Android 8.0:

Unfortunately, official support for updating the Oppo A57 to Android 8.0 ended some time ago. Modifying your phone’s software with unofficial methods is highly discouraged due to potential security risks and damage to your device.

Alternatives:

• Consider upgrading your phone: Newer models will have the latest operating systems and security features.
• Use Custom ROMs (Advanced Users Only): This involves installing unofficial operating systems, which is a complex and risky process not recommended for beginners. It can also void your warranty and impact device stability.

Remember, safety and data security are crucial. If you’re unsure about any steps, it’s best to consult a professional or stick to official update channels.
