I recall that BUILD 920s weren't the first to receive the last update either. Same also goes for generally speaking unlocked and unbranded phones.
I think there were some L920's that got Portico after the BUILD phones. At least, I'm pretty sure I remember reading posts about people in other countries that were complaining about not getting it after I my phone had gotten it.
I'm hoping that the first round of updates was just ironing out the rough edges and that going forward updates will be smoother. I really want the update since the BUILD phones never got 1314 which helps address the LTE bug.
it's my proper carriers firmware, explain how this will void my warranty when it rolls out OTA next week, how will they (Vodafone) be able to tell the difference????"????????
