How to Root N7100

How to Root N7100Big Thanx to Chainfire and Chenglu for great work.
You can get root access by A.Rooting your existing and desired ROM or B.Flashing prerooted ROM. 

Select your choice from one of this
1. Root with Stock Recovery - It will give full root access but have stock recovery. You can set your flash counter '0' and so ready to claim warranty.If you want device full stock + root this is choice for you.
2. Root + Advanced CWM - This will give Root access as well advanced CWM - Here you can reset counter, but once reboot to recovery, it will raise flash counter, Find option to reset counter on every boot (only play store version).
3.Root with ExynosAbuse apk - simply install apk to gain root access. (not works on latest ROM, Jan 2013/LL7 and later)

So which one I should select? OR Which one is better? Both Methods are given by elite developer and both are good, but both having its cons and pros. e.g. Method 1: Disadvantage : Here you will get full root access, but here recovery will remain stock, so you won't have option to flash zip files (still you can flash zip with Mobile Odin), but you won't have any option for Nandroid backup/Restore. Advantage : You have to reset flash counter once only, then whenever you need to reset to unroot/ready to claim warranty, just you need to go to superSU - setting - unroot. So If you are Flash counter conscious and really don't have need for nandroid backup, This one is for You. Method 2: Disadvantage : Note2 having auto check sum boot loader and it will check for custom things on every boot. So rooting with this method your counter will remain 1, even if you have reset it with triangle away. Though one possibility is there to reset counter, you have to use market version of Triangle Away with option 'Reset counter on every boot'. But keep in mind this option only available if your kernel support this, stock kernel won't support it. Again before claiming warranty you need to flash stock recovery. Advantage : You will have feature rich recovery like flashing zip from recovery and Nandroid backup/Restore. So If you are not much worrying about flash counter or warranty and you really need Nandroid backup, This one is for you. Method 3: - Recommended , (not works on latest ROM, Jan 2013/LL7 and later)  Advantage :Biggest thing you can disable exploit and make device safer. Easiest, No PC Needed.  Simply install apk to root device, No flashing/Resetting counter needed. Disadvantage :Camera issue on some FW, but reversible by enabling exploit in one click

Note : normally, phone should auto-reboot into recovery. If it reboots into android and your recovery remains stock, repeat above steps and untick "autoreboot" in odin. Once flash is done, keep pressing power button until it reboots (normally will go to recovery) when in recovery, if you choose option "reboot system now" and you get "yes - disable flash recovery", select that option to avoid stock recovery overwriting cwm

Step 2 :
Now reboot to recovery and flash superSu and busy box file from recovery, which you have copied to Sd card and reboot system
Done ! you should have SuperSU application in drawer. Read post#3 regarding how to reset counter
