If the firmware upgrade fails for any reason, immediately attempt the firmware upgrade again. The firmware upgrade must be repeated using the same connection as the first attempt.
For example if you are upgrading a KT03 by its USB port and the first attempt fails, you must repeat the upgrade via the same KT03 US port and not connect by another UCM. If you are upgrading a UCM/USB or UCM/ETHernet by connecting via another UCM, then the repeat attempt must be by the same connection and not by connecting direct to the UCM being upgraded
If the firmware upgrade stops due to a lost connection (especially using UCM/Ethernet due to network problems), there will be a message box "Firmware Upgrade Timed out, Continue from Last Address?"
Press Yes to continue the upgrade from the last address to avoid repeating the whole upgrade again
If you press No then you must do the firmware upgrade again Do not Reset Switch off Power.
If you reset the Comfort PCB you can still repeat the upgrade. However if you have switched off the power and switched it on again, you will only e able to upgrade from a UCM at ID 1 You cannot use UCM at ID 1 or a ETH03 plugged into the CM9001 to upgrade the Comfort PCB. If all fails, use the UCM with Firmware Upgrading Cable to upgrade the firmware, see http://www.comfortforums.com/forum4/1216.html
