8. Important Warnings

  • Do not upgrade just "for fun". If your F601 works fine, leave it. New firmware rarely adds features – it fixes ISP-specific bugs.
  • ISP-locked devices: Many F601s are customized by ISPs (e.g., SFR, Telmex, Movistar). Flashing generic firmware may remove ISP config but could also lock you out.
  • Downgrading is risky – some versions have bootloader changes that prevent rollback.
  • No official changelogs – you usually won't know what changed.
