OPPO F3 Android 7.1 Nougat Update: What You Need to Know

The OPPO F3’s official Android 7 (Nougat) update is no longer being pushed out over the air (OTA), as the device is past its software support lifecycle. However, if your F3 is still on Android 6.0 and you never received the prompt, here’s how to check for and download the official update. Issue: Phone Stuck on Boot Logo (Bootloop)

Overview: The Update

  • Device: Oppo F3 (CPH1609)
  • Android Version: 7.0 Nougat (upgraded from Android 6.0 Marshmallow)
  • ColorOS Version: ColorOS 3.0 → 3.1 (or 3.2 depending on region)
  • Release Date: Late 2017 – Early 2018 (phased rollout)
  • Update Type: Major OS upgrade
  • File Size: Approx. 1.2 GB – 1.5 GB

⚠️ Note: This is not Android 7.1 or 7.1.2 – it is Android 7.0. Oppo F3 did not receive further Android version updates officially. Cause: System cache conflict

Problem 1: "Verification Failed" or "Signature Mismatch"

Cause: You downloaded the wrong region firmware or a corrupt file.
Fix: Re-download the official package from OPPO’s site for your exact model number.

2. Pre-Requisites Before Downloading

Since this is an older device and the update file is large, you must prepare your phone to avoid "bricking" it (making it unusable).

  • Battery Level: Ensure your Oppo F3 has at least 60% charge.
  • Storage Space: The update file is approximately 1.5GB to 2GB. Ensure you have at least 3GB of free space.
  • Backup Data: While an "OTA" (Over-The-Air) update usually preserves data, it is highly recommended to back up your photos, contacts, and messages to the cloud or an SD card.
  • Stable Internet: Use a strong Wi-Fi connection to download the firmware. Do not use mobile data unless you have an unlimited plan.
