Firmware update failed successfully
I have a PA4010 + WPA4220 kit. I updated PA4010 without problems and in tpPLC utility I can see that firmware version has indeed changed. However, on WPA4220 I get the message that update was successful, but firmware version stays the same. I tried updating via utility and web interface; doesn't make a difference. Firmware I'm trying to upgrade to is official with matching region and hardware revision. I also tried downgrading to older firmware and got the same result - update is reportedly successful but device always returns the same version (220.127.116.11-00_422015_200108_901) no matter what. Why am I stuck with factory firmware and is there something I can do?
