<p>Hello ,</p><p>yes please help us to understand whats wrong because  OTA upstate stalls.</p><p>log file attached.</p><p>first analysis from  my side;</p>

• Request and response sequence for image blocks is fully consistent and correct.
• No block-level transfer errors, mismatches, or anomalies.
• Stall is caused by missing manufacturer-specific protocol handling after block transfer (i.e., Zigbee2MQTT does not handle the Legrand-specific post-OTA command, so the device never completes the update).
