Oppo F7 CPH1819 Download Not Completed Error Fix | Oppo_Custom.bin Solution

If you’re flashing an Oppo F7 CPH1819 (MTK) and encounter the dreaded “Download not completed” error in SP Flash Tool, you’re not alone. This issue usually appears when the Oppo_Custom.bin file is missing or incompatible with the firmware. In this guide, we’ll walk you through how to fix the Oppo F7 download not completed error quickly and safely using the right Oppo_Custom.bin file.

Understanding the Error

• Corrupted Oppo_Custom.bin or missing partition file
• Incorrect scatter file or mismatched firmware region
• Incomplete firmware package (wrong or missing system files)
• Security-protected partition blocked by DA authentication

This error interrupts the flashing process right before the system or custom partition is written, leaving the phone stuck in bootloop or dead mode.

How to Fix Oppo F7 CPH1819 Download Not Completed Error

Step 1: Download Correct Firmware

• Go to MobiFirms.com and download the official Oppo F7 CPH1819 stock firmware (MTK version).
• Make sure it matches your device region (e.g., EX, IN, or EU).

Step 2: Replace the Oppo_Custom.bin File

• In the extracted firmware folder, locate the Oppo_Custom.bin file.
• If missing or corrupted, download the fixed Oppo_Custom.bin file available on MobiFirms’ Oppo section.
• Replace the existing file in your firmware directory.

Step 3: Use the Correct Flash Tool & DA/Auth File

• Use the latest SP Flash Tool version (v5.2112 or above).
• Load the MT6763 scatter file from the firmware.
• In the Authentication File section, add the correct Oppo auth file.
• For better compatibility, use the Oppo_F7_DA.bin (available on MobiFirms).

Step 4: Flash Only “Oppo_Custom” Partition (Optional)

If you only need to fix the partition:

1. Load the scatter file in SP Flash Tool.
2. Uncheck all except Oppo_Custom.
3. Click Download, then connect your phone (powered off).

Once done, you can reflash the full firmware safely.

Cautions

• Always backup NVRAM/NVDATA before flashing.
• Use MTK USB drivers properly installed.
• Do not flash incompatible firmware versions — this may trigger BROM errors or hard brick.
