I tried do update my Varia UT800 (Firmware 2.1) to the newest firmware (2.4), but there's no chance via Edge 520 and Edge 1030 (Firmware 3.6).
Light-network, the lamp and all connections are working, connected via iPhone + Garmin Connect. There is a point "Software-Update" in both Edge 520 and Edge 1030, but without any function. I tried several times to reconnect UT800 + Edge, deleted the connection, synchronized via Garmin Connect. I see no more way to get new firmware on the lamp.
Would appreciate your help. Best regards
