4.3 is a small update from 4.2. Unfortunately, Google also decided to change almost everything about filesystem mounting. And Samsung exynos devices are a hotchpotch of everything...
Today, xplodwild and I carried out a war of attrition against the nasty Samsung devices. Firstly, there remains a battle-scar in the form of graphics, where we had to disable the ability of the device to screenshot itself. You'll see this in the lack of thumbnails for your long-press-home task switcher. #Blame-Samsung
Storage was a nightmare, but I have finally beaten it into submission. It should now work. Nicely. And properly. At least for now.
Because open source is wonderful, a VERY messy device tree (commits need squashed etc) - https://github.com/pulser/android_device_samsung_n7100/
I suggest a wipe before flashing, but I have tested from 4.2.2 and should be OK actually, maybe some apps will cry, but that's not my problem
Pretty much everything is working and tested - you shouldn't have any issues getting it to boot. The other version posted appears it may have issues booting, but I was not aware of its existence until just now. Actually, seems there's no link in the other thread, give this a shot, and see if it helps you. There's a lot of issues on Exynos devices when doing any kind of update... Sneeze and it might explode!
