I was about to flash the Kartini Engine V2.0 (link: http://forum.xda-developers.com/show....php?t=2600244) on my XL, but before I do that I wanted to know how I would revert back to my original state if I wanted to (I'm on stock 4.2.2 build 15.3.A.1.12).
From what I understand, I can either:
1. Reflash the stock firmware using Flashtool or,
2. Restore my nandroid backup
Is this correct or am I missing something here?
Also, for the 1st case even if I don't select "wipe data & cache" options in Flashtool that will still do the job, right?
