Welcome to Vodafone Community
I keep getting the “network error” message each time I try to update the firmware on smart ultra 6. The Wi-fi is working fine and I am still on Android 5.0.2. Any advice please?
Try closing down all your open apps etc and clear the phones ram @Scanner123
Ensure enough storage space is available in the phone and if this was me i'd back up beforehand too.
Forget the Wi-Fi connection settings in the phone and reset them back up.
Then try updating the software.
If you get stuck a Vodafone High street Store will be able to take a look and if necessary send it off.
Just to add I'm assuming your getting the software update from the phones internal update section and not from elsewhere.
