Note2Core Kernel for Galaxy Note II N7100 / N7105 (LTE)




About this kernel
This kernel is built from pure Samsung GT-N7100 source, with modifications and tweaks to provide the best user experience in reliability, performance and stability. Built upon my experience firstly with NoteCore and then HydraCore for the original Note, as many of you know, I strive for the best

There are 3 versions of each kernel, for the International standard Note II GT-N7100 and the International LTE model GT-N7105.

This kernel has all debuging removed - logcat, android log, kernel log, schedular log, etc etc all disabled. This is for performance reasons, so if you are a developer this kernel is probably not for you


For the moment, exFAT formatted SDCards are not supported


Kernel Versions
There are three variants of the kernel for each device

STANDARD (STD) - 1.6ghz FSync() enabled
OVERCLOCK (OC) - 1.8ghz FSync() enabled
EXTREME (EX) - 1.8ghz FSync() disabled

The standard version, has no modifications to the processor clocks or voltages and can be considered a direct replacement for the stock kernel, and with FSync() enabled is completely stable

The OC kernel automatically scales up to 1.8ghz, with the proven voltages and stability from the perseus kernel (the same frequency table is used), and with FSync() enabled is completely stable

The EX kernel also scales to 1.8ghz, and has FSync() disabled. It offers by far the best possible performance. In rare circumstances you must be aware that this can lead to data corruption and the need to wipe / reflash a rom back to the phone. 99% of people will have no issues with this, as it has been extensively tested and proven on my previous kernel, but the risk is there. Dont go moaning to me if you lose your data and haven't got a nandroid backup!



Kernel Features

What processor does that model have? if its exynos try the 7105 kernel, make sure you have a stock kernel to reflash via pc odin if it does not work

edit:

didnt see it was you! hello again nice to see some familiar names around here!

EDIT2 -

before you try it, please send me a .zip fo all the files found in the / (root) of your phones drive (init.rc etc etc) and / or a stock kernel boot.img - I might be able to make one if the 7105 kernrel dont work
