• Keep a copy of the working firmware and bootloader for recovery.
• Document the device’s serial number, hardware revision, and current firmware before updating.
• Test update on one device (if multiple) before mass deployment.
• Schedule updates during low‑use periods and notify users of potential downtime.

• Keep recovery partition minimal but with networking/USB drivers.
• Implement a clear user-visible recovery UI and LED patterns.
• Limit number of automatic rollback attempts to avoid endless loops.

Problem: The update starts but stops at 50% or 99%.

Solution: This usually indicates a corrupt firmware file or a mismatch (e.g., 256M file on a 512M device). Re-download the file from a different source. Verify the sub-version number. 1509 Dvb-t2 512m Firmware Update
