Before I get into it. If you get to a point where you don’t want to go any further, or things don’t work, you can always flash the stock rom (extract the .tar.md5 from the zip) using Odin in your bootloader. Get that here: http://forum.xda-dev…d.php?t=1755386

First off, you’ll need some files. This basically flashes a custom system.img.ext4 which has your su binary. You then boot up and flash cwm

- Odin: http://samsung-updates.com/Odin307.zip
- Rooted system.img tarball: http://goo.im/devs/i….system.img.tar (this is big ~1.5gb, I’ll work on slimming it down)
—–torrent for ^ (please seed!): http://goo.im/devs/i…img.tar.torrent
- CWM recovery.img: http://goo.im/devs/i…35/recovery.img (this was ripped out of CWM-Recovery-LTE-SGS3-Sprint-v4.zip from the e4gt team)

Ok, lets get started….

1. Boot into Odin mode on the phone. Do this by powering off and then holding vol down, home and power to power on. Then press vol up to accept the disclaimer. Plug into your computer.

2. Fire up Odin (Heimdeil may work in linux, haven’t tested) choose the PDA section and browse to wherever you downloaded rooted.system.img.tar then click flash. This takes awhile, be patient. Took me around 8 minutes to flash this.

3. It will auto reboot. It should boot up and thing should act mostly normal except that you’ll be able to adb in and use su to take root

If you don’t want a custom recovery, you may stop here. You are rooted.

Continuing on to get CWM on your device…

4. You’ll need adb installed and working for this. If you don’t know how, this isn’t the thread for that. Open a command prompt and follow these commands:

<cd to the directory with the files you downloaded earlier>

adb push recovery.img /sdcard/
adb shell
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18
adb reboot recovery

5. Profit

Should be it guys. It should be noted I haven’t really tested anything in CWM

I’ve only done it once, but you are welcome to join me in #verizons3 on irc.freenode.net for help
I’m tired, can’t guarantee there aren’t any typos here, if you are scared, just wait. I’m sure someone will come up with a simpler way to do this…

enjoy 

Thanks to many people…

Many others for bits an pieces for this whole thing

FAQ:

Q: It’s not working!!! Keeps failing!!!
A: Try again. Turn the phone off (battery pull) and boot into download mode again

Q: Odin doesn’t seem to be doing anything!
A: Be patient, it can take awhile sometimes. I’ve also noticed if you try to flash something, and leave the phone plugged in and try to flash something else it won’t work. Unplug, then replug, then try flashing again

Q: Does this trip the flash counter?
A: No
