Hi all, Im a little lost here. My Z Ultra has an unlocked bootloader. I still havent received an OTA notification for lollipop. (I'm running KitKat). I have a C6833, I just tried updating through the sony software, it did find the update but said my phone had modified software and therefore could not proceed.

So how do I upgrade to Lollipop ? I have tried looking for a TFT rom for the update but havent found one yet. My girlfriend upgraded OTA and its got the 14.5.a.0.242 . Havent found that TFT file for download though

EDIT: Well, for anyone interested, i found this :
