Hi,
I need to downgrade a 622 dect phone to get back the original firmware.
Today the versions inside the phone are 7.0.SP8 & 7.0.SP10 (Bluetooth 3.2.1)
The older "none GAP" version is not available from the ***76# Downl. / Switch to ... menu.
Any tip how to downgrade the firmware and where to download the tool?
Regards
Verner
