Rooting Note cannot find/unavailable ROM

Hey Guys,

I am new to rooting so please take that into account.
Basically what I am trying to do is to root my Samsung Galaxy Note in order to remove the limit of the amount of text messages that can be sent per hour.

I am following this tutorial on how to root it: http://forum.xda-developers.com/show....php?t=2217840

Method 1, where you easily just download an app that roots it, does not work for me - this error comes up: FAILURE: Could not root device

Method 2, which is where you download the kernel based on your ROM is what I am now trying to do.
However the link it provides to download the roms from: http://forum.xda-developers.com/show....php?t=1901191

Does not appear to have my ROM/Kernel. Please help me out.

This is some information about my device:

Model Number: GT-N7000
Android Version: 4.1.2
Baseband version: N7000XXLT3
Kernel Version: 3.0.31-1103517
Build Number: JZO54K.N7000XXLT9

Not really sure how to do this. Please advise. Nothing for XXLT3 or XXLT9.

Thanks in advance,
