There are two reasons why "Unpack failed - damaged or wrong package format" may be displayed when attempting a radio software release upgrade:
- The newly-loaded software package is the same version of the software currently in use on the device
- The software packages have been unpacked prior to uploading to the device. Software upgrade packages uploaded to the radio should always be in the format [radio type]-[software version].tar.gz. For example, to upgrade to software release 2.4.3 via the device web interface, upload either ePMP-NonGPS_Synced-v2.4.3.tar.gz or ePMP-NonGPS_Synced-v2.4.3.tar.gz depending on device type.
