CF root XDA thread
Unboxing, initial impressions & pictures

After rooting my device, being on LE8, the LF2 update came out.
I thus decided to upgrade via KIES, whilst being rooted.
Upon upgrading via Kies, to LF2, where my S3 successfully, whilst being rooted with CF root, lost root, after upgrading officially with Kies.
I thus was on LF2, officially via Kies, but had no more root.

I went ahead, after losing root on the LF2 upgrade, and regained root, via the same method.
I just thought I should mention this for people wondering about losing root after upgrading via Kies.

Hope you enjoyed the guide!
