[Revised] How to use SP Flash tool to flash Mediatek firmware

MediaTek Helio P35 (MT6765)

The is a popular octa-core processor used in numerous mid-range smartphones from brands like Xiaomi, Oppo, Vivo, and Samsung. If you are looking to unbrick your device, install a stock ROM, or update your firmware, the Smartphone (SP) Flash Tool is the essential software for these tasks. Choosing the Best Version for MT6765

  • Always confirm firmware source and integrity (official vendor ROMs or trusted forums).
  • Avoid using “Format All + Download” unless instructed; it erases IMEI and calibration data if not handled correctly.
  • If IMEI or calibration data is lost, restoring may require backup files (nvram/efs); always back up these before flashing.
  • Use “DA” (Download Agent) files supplied with firmware if required; wrong DA can fail flashing.
  • Use readback or backup functions to save critical partitions before modifying.
  • Document device model, firmware version, and scatter mapping to reverse changes if needed.
  • If uncertain, seek device-specific guides—some models require special steps (test points, preloader differences).
  1. Open SP Flash Tool.
  2. Load the Scatter File.
  3. Select "Firmware Upgrade" (recommended).
  4. Hit Download.
  5. Power off your device completely.
  6. Connect the phone while holding Volume Down (optional, but helps detection).
  7. Wait for the green checkmark of success!

Even with the best tool, errors happen. Here is the fix matrix.
