Android 4.4.2 cannot update using PC Companion

[FelixWan]

as title,
once the phone is plugged, PC Companion just said "your phone is update to date"
but my phone is just 4.4.2 which should have 4.4.4 for update now.

I received the 4.4.4 update notice from my phone's "Update Center" few days ago, which said it need to be done through PC.

But when I have time to do this today, it just can't detect the latest update?

what can I do to enable the 4.4.4 update?
I don't want to use flashtool......
