When I setup a Provisioning Polycom Soundpoint 331 phone, and in the EPM, I chose a new firmware. When the phone rebooted, it seems to have downloaded the firmware and installed it. once the phone restarted and I think it was going to start the provisioning process, and just before, and right after the “setting up network settings” step, it said “Image is not compatible with phone” and continuously loops to restart.
Previously, I think I deleted all its apps and reformatted its filesystem thinking that it was the way to “factory reset” the phone.
What is the best step forward to resolve this problem?
