The easiest way to update the software on your Jongo device is by using the automatic update method which is delivered via the Wi-Fi connection.
 
After 1 hour of the Jongo device being in standby (plugged into the mains), the Jongo will perform an automated routine that checks its current software version against the latest available version on our update servers – to ensure it is up to date and running the very latest software version.
 
Manually installing software on the Jongo A2
 
Check list:
 
You will need a freshly formatted USB stick to perform a software upgrade on your Jongo A2   
You will need the latest software download for the Jongo A2. You can get the latest software from here http://support-uk.pure.com/downloads/118-software
You will need a decompression tool like WinZip installed on your computer.
 
Preparing the file and your USB stick
 
When you download the file to your computer it will arrive as a compressed file (.ZIP) that will need decompressing. Use a decompression tool like WinZip to decompress (or ‘unpack’) the file, and save the file to a location on your computer that you will easily find. There is only a single .dfu file in the zip to save.
Make sure your USB stick is freshly formatted with no data stored on it.
Now copy or move the unpacked .dfu file to your freshly formatted USB stick. The .dfu file should be the only file present on the USB stick.
