OTA update won't work when your android device rooted, you need to full unroot first to get OTA update

It seems that one of the users (another threath LG H900 5.1 > 6.0 problem) is right and I upload software h900 6.0 via KDZ via TOT even via octopus and nothing, even the same error is possible that the main card is not h900 but another variant?, He says he solved the problem by loading vs900 software because the main card was not h900 but refurbished vs900.
I opened the phone and I was right, now i am going to load the correct software and tell you.

Once you confirm the model of your phone and I find myself developing a tutorial to load the kdz but only if the version is equal to or higher than the one they currently have downgrading kills LG phones with antirollback
