Is there still a problem updating to 4.3? KNOX?
How should I update to 4.3? Do it need to undo root and go back to stock recovery? I'm not sure how to do this. I have used custom ROMS in the past but it's been too long.
Also, it seems that rooting 4.3 is no problem. Is this true?
Sure, you can upgrade to 4.3 if you want to
the reason why people said not to upgrade to 4.3 is because a lot of people DO NOT READ and come asking for help this or that after they upgrade
and the main reason why people mention not to upgrade is because you can unlock for free as long as you can downgrade your phone to 4.1.1, mainly the bootloader since 4.3 bootloader comes with KNOX
since you're still on 4.1.2, you can downgrade and unlock your phone for free while you still can before upgrading it to 4.3
so this is what you should do, check, if your phone is fully unlocked, if not, unlock it then upgrade
or if you're rich and you don't care, just upgrade and then if you wish to unlock later, pay for unlock code =D
and rooting shouldn't be any problem regardless of which version of android you're on.
to upgrade, you can just download the stock img and flash it through recovery or just use odin flash it
or if you're prefer the old fashion way, the long way in fact, is to unroot, upgrade through system update
