What do you mean when you say "Flash it"? What do I select in ODIN to flash the kernal? I unrooted my phone and wiped all the data. Am I supposed to boot it in download mode? Soooo confused:-(

It's not that hard to use Odin. Kinda hard to explain it but if you look at the pictures and instructions in the following link you should be able to figure out what to do with it.

Just make sure you pick the right rom for your phone....As in SGS2 for AT&T
