Complete Fix Methods for Error 8038

Fix 1 — Use Rear USB Ports on Desktop

The most common cause of error 8038 is using front panel USB ports which provide insufficient power for BROM communication. Always use the rear USB 2.0 ports directly on the motherboard of your desktop PC. On laptops, try different USB ports and avoid USB hubs.

Fix 2 — Change USB Cable

Use the original USB cable that came with the device or a high-quality data USB cable. Avoid cheap charging-only cables as they lack the data wires needed for BROM communication. A damaged cable is responsible for error 8038 in many cases.

Fix 3 — Reinstall MTK USB VCOM Driver

  1. Open Device Manager on your Windows PC
  2. Uninstall any existing MTK VCOM driver
  3. Download latest MTK USB VCOM Driver (available on this site)
  4. Install as Administrator and restart PC
  5. Try flashing again

Fix 4 — Disable Antivirus and Firewall

Windows Defender and third-party antivirus programs often block SP Flash Tool operations. Temporarily disable all security software before running SP Flash Tool. Also run SP Flash Tool strictly as Administrator.

Fix 5 — Enter BROM Mode Correctly

  1. Power off device completely
  2. Remove battery if device has removable battery
  3. Open SP Flash Tool first and click Download
  4. Then connect USB while holding Volume Down
  5. For non-removable battery: connect USB while holding Volume Down with device off

Fix 6 — Try Different SP Flash Tool Version

Some MTK chipsets require specific SP Flash Tool versions. Try SP Flash Tool V5.1920, V5.2124, and V6.x to find the compatible version for your device chipset.

Fix 7 — Handle Anticrack Protection

If your Tecno, Infinix, or Itel device has Anticrack protection, error 8038 may appear due to authentication failure. Use MTK Auth Bypass Tool V6 alongside SP Flash Tool — start the bypass tool first, then click Download in SP Flash Tool, then connect the device.

Fix 8 — Use Format + Download

Sometimes switching from Download Only to Format + Download operation in SP Flash Tool resolves error 8038 on devices with corrupted preloader partitions.

Step by Step Troubleshooting Sequence

  1. Close SP Flash Tool completely
  2. Disable antivirus
  3. Unplug all USB devices except mouse and keyboard
  4. Reinstall MTK driver
  5. Open SP Flash Tool as Administrator
  6. Load scatter file
  7. Click Download
  8. Power off device, remove battery if possible
  9. Connect to rear USB port via original cable
  10. Hold Volume Down while connecting

Conclusion

SP Flash Tool Error 8038 is almost always solvable by following the troubleshooting steps above. The most effective fixes are using rear USB ports, changing the USB cable, reinstalling MTK drivers, and properly entering BROM mode.
