How to flash kernel via mobile ODIN

[TLG]

Hello I have a Samsung Galaxy S 2 that I bought from Boost. I rooted it with framaroot. I also downloaded Mobile Odin just to see If I needed it in the future. Well I wanted to flash a kernel to it. I was just wondering how. Here's my device info.
I'm one 4.1.2 Jellybean and my software version is Gc01. My kernel version is. Can someone also point me to a good kernel with custom recovery? Thank you.

Either of these will work:

version 0.4.1 or 0.5.0 of this one, and you want the .tar file for Mobile Odin

Rwilco12's Android Repository - Downloads

or you can use this one:

[UPDATE][KERNEL][SOURCE] JB GB27 v1.4.2 with AGAT tREC_v0.3.5 recovery 08/14/13 - xda-developers

again you want the .tar file. Both of these kernels will run GC01 just fine and can be used as a daily driver.

Ok I downloaded a .TAR file named Sxtp_agat_gc01-0.5.0. Is gb27 and gc01 identical? Also when I load up the tar file on Mobile Odin, do I have to click flash firmware button? Sorry I'm a newbie at this and don't want to ruin my phone.

Yes, GB27 is just the build number for the sprint labeled version of the same ROM. Yes to do the actual flash of the kernel you have to click the flash firmware.
