Question about kernels and roms.

I'm still pretty new to this. If I flash a new rom (in this case CM10) does it also flash a kernel? If I am on cm10 and flash a new aosp based kernel and decide to go back would I flash the stock Samsung kernel or is there a special one for cm10?

All ROMs include a kernel, without one it wouldn't boot. If you flash a new kernel after installing CM10 and want to revert to the old kernel, just flash the ROM again without wiping data and it will restore the kernel.

Not all roms contain a kernel fyi so keep a few on your sd card just a heads up

I didn't know that. Guess it's cause I always flash KT747 right after.

Upgrading to ice cream sandwich/jelly bean

I'm trying to upgrade a Tmobile galaxy s2 to jellybean that's currently running GB rooted with a custom rom. I tried simply flashing a newer ROM (ics then and jb ) but it wouldn't finish booting. I searched like crazy but I can't find any sure answers, is there a guide for my problem or something I should do like firmware update? Thanks!

You should use odin to flash the official ICS first before jumping to ICS and JB roms

You don't have to do anything but flash the rom you want and an updated radio. I flashed gb to ics to jb numerous times. No need for odin.

That's a relief. Thanks! I tried flashing cm9 and all I got was a bootloop. I'll do the radio as well though
