what is ur specific problem? pls give details.
Have u read creezalird's guide? If u not sure, look up creezalird, he is a forummer here and look at this signature , there is a link to his guide. Most complete guide u can find. If u use that, sure no problem.

I think u are having problem because DZKL3 is not rootable with normal Doomlord method.
I suggest you
1.Downgrade back to DZKJ2 using ODIN.
2.Then root with Doomlord.
3.Install Mobile Odin
4.Download DZKL3 firmware.
5. Download superatmos kernel 2.1.1 ( based on DZKL3)
6.Install K-tool and use it to flash superatmos kernel 2.1.1
7.Use Mobile Odin to pre-root and install the DZKL3.

And u will have a DZKL3 that is rooted and also able to use KIES to check for updates

Of course if u have USB jig u can skip some steps like # 2 and straight away flash superatmos kernel 2.1.1 and use jig to remove yellow triangle and binary counts.

Try the above. I used it as well. Running rooted DZKL3 now with CWM recovery too.
