Hi, i tried to install 3 CP 521S in a site with UC520.
2 of them upgraded correctly their firmware.
The third got unplugged while downloading the firmware and now it is stuck and displays as soon as it gets plugged in:
"S.O.S. Phone in Recovery Mode".
I found the rec-spa941-5-1-8.exe and the rec-spa942-6-1-3a.exe but i cannot make it work.
Any help will be appreciated.
