You can use that one if you are on unblocked bootloader.
On which version you was before?
If you was on jb and you flash a kernel for ics it won't boot.

You want to flash just the kernel or the Rom mate? You can't flash ics kernel on jb rom. You have to flash or ics or jb.
If you want to downgrade to ics, just flash the ftf file.
I'm using the app and I can't see the whole screenshot mate, sorry

I don't understand where is the problem, you are now on ICS, you can't just flash some .62 zip via CWM. By doing that you will only(most likely) replace system partition, other stuff like kernel, baseband, data will be left from ICS.
ThilinaC told you to do a full flash first. Meaning, first flash some GB ftf, then root, then CWM, and then you can flash that zip in CWM.

hm, my advise:
flash .42 ftf, root, CWM, flash that zip you linked, and then flash stock .62 kernel(you can flash stock even on locked BL, of course if you don't have SIM-lock, meaning if your fastboot is enabled)
or you can check this tutorial: http://forum.xda-developers.com/showthread.php?t=1468866
and get .62 via OTA update, after flashing .42.

Secondly, flash stock firmware and then flash another kernel
Thank you guys. Solved the problem by flashing rage kernel. Sorry for posting in wrong section. It was not intentional.

If you were able to flash the rage kernel and DDS kernel then that means that you have an unlocked kernel. Also if you are able to boot into fastboot then you have an unlocked bootloader.

If you said that you solved your problem flashing Rage Kernel, then your bootloader is unlocked. Cause locked bootloaders cannot flash kernels

On stock rom type *#*#7378423#*#* -> Service Info -> Configuration -> Rooting Status: Bootloader unlocked: yes

its pretty obvious.. when you flash the stock rom manually, some of the stuffs are not in order as the factory one even if the version is same.. so to put it in order perfectly you have to install the update...

Yup, no need to fastboot again, put the ROM in your sd card, go into CWM and flash it, with the flash you will have the newest kernel too :good:
