Various other fixes Notes: RN40： Due to changes in the firmware upgrade method, if you are upgrading from the previous 2.x series to this version, you need first install the transitional package (RN40-9999-upgrade-firmware, then manually refresh the web page), and then upgrade to this version (RN40-3.01.0010.0003-full-upgrade). If you have already upgraded to the 3.x series, you need first install the transitional package (firmware-RN40-kiloview-3.01.9999, then manually refresh the web page), and then upgrade to this version (firmware-RN40-kiloview-3.01.0010.0003). Due to changes in the upgrade mechanism between versions 2.x and 3.x, an upgrade from 2.x to 3.x may display “Cannot connect to CODEC service”, which can cause the upgrade to fail. Please run the upgrade again; in most cases, the upgrade will complete successfully on the second attempt. (After upgrading to this latest version, future firmware upgrades will no longer require the transitional package.)
