I rooted my note 8 prolly 1 to 2 years ago, and did not do much else except add a few programs that required root. I am on Android version 4.1.2 .When I try to update it through the software update in the about device in settings, I of course get an error message that says my device has been modified, software updates are not available.

So my question is this what version should a stock Note 8 GT-N5110 on had I not rooted my device.....and I have heard that KitKat is horrible... so should I just go back to stock and stop at Jellybean AND How do I get back to stock? or is their an easier way to get to jellybean while being rooted? Is Lollipop a possibility .(I just got it on my Note 3 and like it alot!)
