Huawey p8 EMUI not updating

[AC Question]

So, i have a huawey p8 normal and my brother has a huawey p8 lite and i noticed his emui updates to 4.1 to support Android 6.0, while mine ( which supposedly is a superior model ) is still at Android 5.0 and my emui is 3.1 and i cant get it to update no matter what, the updater isn't detecting new updates and this is starting to really **** me off, bcs i have no idea if the update for huawey p8 is just delayed or if the problem is with my phone, any kind of help will be useful, thanks.
