Alright, noob here too, and I've looked high and low, and I cannot for the life of me find out how to flash kernels/roms using Odin. Anyone wanna help out?
Dont worry. The easiest way is to Root your phone + Download Rom manager from the Market + Install Rom manager as directed + then use Rom Manager itself to install the preferred rom.
Reminder: depending on which Rom you install, there are specific instructions on how to install them as well. READ + READ. Usually if you go to the OP of the acutal Rom you are looking for, it will give you step by step info on which is the best method of installing.
Also, keep in mind that YOU MUST be able to go into 1) recovery 2) download modes with the 3-button key combo as a safety precaution. It is very, very, VERY helpful....unless of course you are familiar with ADB.
Other methods include downloading the ROm + rename to "update.zip" + place in your Internal SD card + boot in recovery + re-install packages.
Odin is for more advanced users as it requires knowledge of different files to attach to Odin WITH, and then installing with Odin (ex: Kernel swapping).
There is also Odin One CLick, however, DO NOT confuse that with the regular ODIN.
Good Luck!
