How do I permanently prevent Note 2 from OTA updating to 4.3?

This is a simple root fix. Just use this app called framaroot. Its a one click root application. All you need to do is install it and click the section called Argorn.
Your note 2 will be rooted then. Please dont try the firmware restoration version because it can brick your phone.
To install Framaroot, you need to go check

Settings/Security/Unknown Sources

Heres a link to Framaroot 1.9.3

When finished you can follow the Synycalwon guys steps.
Finally this is a step that many people dont do but it will sace you 100 to 400 megabytes. Go to the file manager and go all the way to the root and click on the cache folder. Then delete the zip files because they are all the ota updates that were downloaded.

Just for future reference for users with the AT&T version (sgh-i317), instead of SDM.apk, it's wssyncmldm.apk. Couldn't find that info anywhere online. Finally checked running processes and figured it out. Same location. Also used Root Browser instead of the other explorers.
