Recently I returned my phone to stock with this RUU http://www.htc1guru.com/dld/ruu-zip-...78_signed-zip/.
After that I installed all possible updates for the phone.
Now when I look at the Software information I get:
Android version 4.3
HTC Sense version 5.5
Software number 3.62.401.1
HTC SDK API level 5.65
... and when I check for updates phone says that there are no updates available for my phone.
Why? Where is Android 4.4.2 for me?
