Default 4.4.2 i9505 Firmware for Australia 4G LTE

I've got a rooted, unlocked i9505 with firmware 4.3, and knox still at 0.

Been waiting patiently for an official XSA version of 4.4.2 (Kitkat) and nothing in sight.

This morning, the Google Play Store has been acting up, giving connecting/server errors. Have cleared Google Services Framework cache/data, Play Store cache/data as well as stopped, disabled and re-enable both Framework and Play Store to no avail.

The next step is a hard reset.

Given that I will be losing all info on phone, was wondering if there is safe 4.4.2 firmware I can upgrade to that will permit the 4G LTE/GSM network in Australia before flashing to the official firmware when it is released?

Thanks in advance
