I have recently upgraded the firmware on our 7921G wifi phones, from 1.1(1) to 1.3(3). To authenticate against the correct wlan we import a backup.cfg file and it imports the correct ssid and key etc. The issue is that after the import and phone reset it then tries to download the firmware again and fails. And if the phone is turned off or restarted it looses all it's settings from the backup.cfg file and we have to go through the importing all over again. The hardware revision of the phones is 1.5. Any help is appreciated.
I ran into this issue as well. To upgrade the firmware from 1.0.3 to 1.3.4 you will have to do a 2 part upgrade. Upgrade it to 1.1.1 and then to 1.3.4. That should work fine. It is common for a lot of phones when making big jumps in updates to firmware.
