I am using an unlocked SPA504G 4-Line IP Phone.
It is currently loaded with firmware 7.5.2 (H/W 1.0.4)
I was looking to upgrade to the latest FW version, which I found at the following location: IP Telephone Firmware-7.5.7
When I run this update, everything appears to be working as it should, but at the very end of the process, the phone resets and the update program hangs at the end and after a minute just closes.
No errors occur, and the firmware remains unchanged. i.e. It has not updated.
Hoping to see if anyone can suggest what is going wrong here.
