I own an IoT Cricket which is running FW version 2.2 and I am trying to upgrade to 2.4
When I run the "Check for upgrade" it finds FW version 2.4 correctly. However, when I try to upgrade it always fails. The progress never gets any further than about 50%, although many times not even that far: 0%, 17% and the highest I saw sofar was 51%. I must have tried it over 200 times now, without any success. The little blue LED is blinking very rapidly when the upgrade starts, but fails after a few seconds while the browser shows "FW UPGRADE ERROR". Can anyone help me here? My hardware version is 1.0 by the way and both my Wifi connection and internet connection are excelent.
