If you are unable to update the firmware of an old eWON (Serial number is older than 0648-xxxx-xx),you should probable upgrade the bootloader to the v2.
To take advantage of new features, fixed issues, a more stable system… you may need to upgrade the firmware of your eWON. This one is in constant evolution for which each update brings improvements.
To let you keep track of all releases, we update a text file each time a new firmware is out with its changelog. You can find this file here: release.txt
Currently, there are 2 different methods to upgrade the eWON firmware:
Via eBuddy software
eBuddy should be the primary choice. Via this Companion tool, you will download the latest firmware version available for your eWON on your computer. Once downloaded, eBuddy directly upgrades the firmware on the eWON. All is performed in one place: the eBuddy software.
If you need a major upgrade (for example: from v7# to v8#), you have to perform a recovery in order to install the new firmware version.
Via FTP client
The FTP solution should be considered as an alternative. The firmware upgrade file can be downloaded manually on your computer and then uploaded on your eWON via an FTP client. If a major upgrade is needed (for example: from v7# to v8#), you have to perform a recovery in order to install the new firmware version which can only be done using eBuddy.
Note: Even if the upgrade process (without recovery) doesn't erase any configuration/data of the eWON, it's always recommended to make a backup before. Just use the Backup/Restore Application wizard in eBuddy to create a backup of your eWON configuration (and application or program).
There is also the possibility to downgrade the firmware version. This is a specific case and we suggest to be very cautious when trying a downgrade.
