Not exactly... After this method the phone status remains "rooted" when booted in download mode. Couple of users reported this problem...
Edit: here's the fix http://forum.xda-developers.com/show...php?p=52991286
Sure. But after you flash kdz file with flashtool the phone isn't rooted anyway, although in DLM it states "rooted"...
As I undrstand it, somehow after you flash kitkat kdz it misses some files and status "rooted" appears in DLM. Explained here: http://forum.xda-developers.com/show....php?t=2703501
