Folks over at XDA has Developed Root Method for AT&T Samsung Galaxy Note which is going to hit retail stores today. With the developer’s ODIN-flashable pre-rooted kernel, you can now use custom boot animations, adb root, init.d scripts, and more. In the words of the developer:
This kernel enables custom boot animations, adb root, init.d support, runs a script to auto-root your /system partition, and then you’re on your merry way You may need the USB Drivers available here. (Support & Downloads for SGH-I717)
Once the USB Drivers are installed, power off the phone, then hold volume down and power it on, you’ll get a screen asking you to hit vol up to continue, do so. This puts the phone in download mode.
Stick the provided pda.tar in the PDA box of Odin3 1.85, flash away!
Install Superuser from the market after booting.
Those that are interested in doing this should realize that there are some dangers, though. There is a risk of voiding your warranty and/or bricking your device. If anything happens, the owner is the only person responsible for such results. With the disclaimer out of the way, just be careful about making the decision, take your time, follow instructions, and read the material before executing the procedure.
