So there seems to be alot of confusion as to just how odin works. This is understandable since there are alot of different variables with our phone and thus a lot of links and text to read through and it may seem overwhelming to some. This is a video tutorial showing how to install cwm with odin. Once you have CWM you can flash files directly to your phone from it and will not need odin again unless you choose to go back to stock or use it to install some odin specific file. Odin - a phone flashing program run from your computer to install stock and custom images. Your phone must be in download mode to use it (Turn phone off, press and hold vol-, power, and camera button, release power button when samsung logo appears). Often Odin is a tool that can save otherwise bricked phones since most bricked phones can still boot into download mode. CWM - a phone flashing program run directly from your phone to install stock and custom images. CWM takes the place of the recovery program that came with your phone so your phone must be in recovery mode to use it (Turn phone off, press and hold vol- and power, release power button when samsung logo appears). ***NOTE*** Before following any of these steps be sure to have a recovery file ready to flash on your phone in your /clockworkmod/backup/ folder on your sdcard. Make the folders if they do not exist. The recovery file found here is 2.3.6+root odin cwm - YouTube ***NOTE*** 2.3.6 users, once your phone reboots from odin after the flash it is important that you unplug your phone and pull the battery before it boots. Otherwise the file samsung put on your phone in the update will just overwrite cwm with their stock recovery and you will have to start all over again. my phone rebooted at 8:32 in this video and you can see how odin changed its recovery﻿ text to say "reset". this is when you need to unplug and pull battery. Once you pulled your plug and battery and phone is off, put battery back in and boot it into CWM (press and hold vol- and power, release power button when samsung logo appears). If you boot it normally you will have to start all over again because just like above, the file samsung put on your phone in the update will just overwrite cwm with their stock recovery. From here you should flash a recovery﻿ file. If you want 2.3.6 with just root I recommend the file katracho posted here. The instructions on this link do not apply but you must have a recovery file on your sd card to flash to before doing any of these steps or run the risk of having to reflash cwm all over again because you had to boot your phone up to add them to you microsd card.
