Rooting and flashing ROMs does come with risks, but considering
Samsung isn't supporting your device any longer and it is more than
likely out of warranty, unless you really can't afford to get a new
device if something goes terribly amiss, you should be fine. Just follow
the steps outlined below carefully, and if you're not sure, do not
proceed until you get some clarification.
A few things to note
The ROM file contains a kernel modified specifically for this ROM.
This ROM is heavily debloated.
This ROM does not supports any other custom kernels including the arter97 kernel.
This is based on Korean firmware, some stuffs may remain in Korean(e.g. Dialer).
BusyBox or Superuser are not included with the ROM.
You will need to have your KitKat rooted before you are able to install this, please follow our previous root tutorial guide for the Galaxy S3.
Installation
Install a custom recovery, such as TWRP Manager.
Place the ROM on your internal memory.
Enter recovery.
Make a full data wipe (wipe cache, wipe dalvik, format system and
wipe data). However, if you are already running a previous version with
the back-to-n00t, this will not be necessary.
Flash the ROM.
If you don’t already have it, flash and install SuperSU.
If you’ve done the steps properly, you will not have the official
KitKat ROM ported to your international version of your Galaxy S3. Let
us know in the comments whether this worked for you!
