[Q] getting stock rom through kies topic

Hello, so I just flashed 4.4.2 via odin on my n7505 because the update wasn't available in my country but I don't really enjoy the rom was tweaked and full of bloatware. It was not branded and yet it contains bloatware and even this thing called ultra power saving mode which doesn't work by the way. I tried getting it to stock rom via kies but when I click Firmware Upgrade and Initialization under the tab Tools it has blank space after Initialised version: which is quite odd in my opinion. When I click Ok it says my phone doesn't support initialising. Could it be my CSC? Originally it was BGL and now after flashing 4.4.2 it became ETL. Can I change it? My phone's not rooted but I don't mind rooting it if I have to. Gonna be really nice if you help me out :)
