The thing is: if you didn't already get an update OTA / via kies (since samsung rolled out kitkat in germany a few days ago) chances are, you are not having a german phone, like myself.
so please enter *#1234# into the dialer app and post the results
also, it would be nice to know your country/product code: if you happen to have the box the phone came in, check the label where your imei and gsm frequencies are mentioned.
There, you'll find a string like "SM-N9005ZKEROM
" which (in my case) means a black
note 3 from romania
or hook it up with kies and tell the last three characters between the brackets in your firmware version
to your first question: uncheck it. AFAIK, if it is set, the firmware will flash a new bootloader onto your device, and in most cases you don't want that, it could mess your phone up badly. correct me if i'm wrong.
Back to the rom, which also addresses you 2nd question:
The actual problem with simply flashing the DBT rom is that the EU devices happen to be partitioned differently from the german ones, so [U]odin will fail[U] if you have a device with an uncompatible CSC/Product code (e.g. an east-european device), which in turn may or may not
trigger knox and/or void your warranty.
i currently try to get more information on that topic.
nevertheless, pocketpc.ch provides a tutorial which mentions flashing DBT firmware along with a custom pit file, which may or may not void your warranty, but doesn't seem to trigger knox (pm me for a link or google it yourself: "Flashen der DBT-FW auf EU-Geräte")
