3) Once you have clockworkmod installed, you will have to visit the jedi thread on your phone and download the jedi rom onto your phone.

4) once the rom is downloaded onto your phone, shut your phone down and boot into clockworkmod by pressing volume up, home button and power buttons all together.

5) once in clockwork mod you will use the volume up/down buttons to navigate and then the power button to make the selections "install zip from sd card" and then "choose zip from sdcard"

6) Clockworkmod will then give you a list of all the files on your phone, and you will have to select them accordingly to find where you downloaded the jedi rom to and once you find it, you of course will make the selection to install it. Don't forget to use clockworkmod to "wipe cache" and in "advanced" to "wipe dalvic" in the order that is stated in the first post of the jedi thread under "instructions". This is important. Don't do things out of order.

If you go to the bottom of page 141 in the Jedi thread, you will find a long post that takes the instructions from the first post to flash the rom and writes them out in greater detail to make it easier to understand. Follow those in order and you should be fine. Also, so you can see it in person so to speak, try a search like "flash rom clockworkmod" on youtube and watch someone do it. If you can find it for your phone even better. It makes it a little more comfortable to do it when you've seen someone else do it first.

You do not need to worry about flashing carrier files with your phone because the Jedi rom is built around at&t already and includes them in the original download.

Some of your questions answered:

When it says desired modem, does that mean that's optional or I need to pick one? You don't need to worry about modem at all with your at&t phone. skip it.

What is nandroid and what do I use it for? Nandroid is a snapshot of your phone. When you boot into clockwork mod, you will see the option to "backup" your phone. You do this so if something goes wrong while you are flashing the Jedi rom, you will be able to go into clockwork mod and reset your phone with the backup you just made. That is called nandroid.

Next, what is the factory data reset and how do I perform it? Factory data reset is an option you will see once you boot into clockworkmod. Just select it using the volume up/down buttons and it will wipe all user data from your phone and put it back to the way it was out of the box. Once the process is finished however, you will still be in clockworkmod and can proceed to the next steps to flash the rom.

I've downloaded CWM (ROM Manager), is this the right app and do I use that app to wipe the system? Once you have installed clockworkmod on your phone using odin, you won't need to use the Rom manager app. just stick to booting into clockworkmod and performing tasks there. Later when you're more comfortable with the process you can play with rom manager.

How do I actually flash the system? Flashing will happen whenever you choose to have clockworkmod install a rom or addons or whatever.

How do I wipe the cache and what is dalvik? Both are optional actions you can perform in clockworkmod simply by selecting them. Wipe Dalvik can be found under the "advanced" settings. These need to be performed to help ensure that the rom you choose is installed correctly.

What permissions need to be fixed and how do you do that? Fix permissions is simply an option to choose once booted into clockworkmod. It literally only takes a few seconds.

How do I flash the carrier files, modem and add-ons? You can download the add ons to your phone after you flash the rom, boot into clockworkmod and follow the process of "select zip from sd card to install" don't forget to follow the apprpriate steps to wipe cache and dalvic, etc when you flash add ons.

Read twice, flash once.

Best of luck!
