Step 5: Flash Full Firmware with SP Flash Tool
- Open SP Flash Tool → Load the scatter file from your full firmware folder.
- In the “Download” tab, select Format All + Download – this erases the MDM enrollment flags.

- Click Download.
- Wait for the red, purple, yellow, and green progress bars (approx 5–8 minutes).
For OTA Update Removal or Reverting:
