Important note Before Using DIAG Mode
Always keep in mind:
- Back up your NV/EFS data before making changes.
- Don’t modify values randomly in DIAG mode — incorrect edits can lead to network loss or IMEI issues.
- On some models, DIAG mode will turn off after reboot — so re-enter the code if needed.
- Not all phones will support these codes. Success rate depends on brand, software version, and security update.
Use responsibly. Always take backups. And only modify what you understand.
