I live in Australia and as such I have the D802T.
Not so long ago the phone offered offered to update to 4.4.2 from JB I guess. All was well except GPS became very intermitent. After some mistakes with applying TWRP I eventually got a French Vodafone 4.4.2 ROM loaded (via TOT method on this forum). With this ROM i had no GPS issues but lacked 4G. After more searching I changed a line in "build.prop" and now have 4G, I also had to update Touch settings for 'Knock On'. I managed to find the 4.4.2 Optus KDZ file and created a ZIP firmware, but after applying I still had the GPS issue so went back to the French TOT ROM.
I called Optus and they have no idead so I wanted to know if other people had experienced GPS issues with the Optus branded 4.4.2 update?
Also, does anyone have the JB 4.2.2 Optus ROM? I have searched but only fidn the latest 4.4.2
