Oddly this update appears to no longer be accessible via OTA. Today, I restored my phone back to JDQ39. After booting up, it downloaded and installed the JWR66V OTA without issue. Once that finished, however, it couldn't find the update to JWR66Y. Checking for updates would just say the system is up to date.
It doesn't really affect me, though. I just did adb sideload to install the OTA manually. That worked fine. Still interesting, though.
