For those of you who have bricked your Galaxy Note 2 (perhaps ended up in a bootloop), want to return to stock firmware (because you forgot to make a backup ROM!), or you want to return your Note 2 back to Samsung Service center for warranty, here’s how to unroot/unbrick your Galaxy Note 2 with stock firmware.
Also, you can use this method to update your stock ROM to the latest stock firmware. For example, if Android 4.2 comes out, you can use this method to update instead of Kies if you want.
First, if you are rooted, I HIGHLY ADVISE you to make a backup ROM (see How to Make Backup ROM). And after making backup ROM, do MAKE A BACKUP of your internal storage by copying everything to your hard disk. If something goes wrong, you will be able to do a factory reset in stock Android recovery and get all of your settings, apps, photos, and videos back.
Also, if you are on a ROM like CM10, AOKP, or any ROM that’s non-Samsung, non-TouchWiz, you will definitely need to do a factory reset. You can also do a factory reset in CWM Recovery BEFORE unrooting, that will not erase the contents of your internal storage (then you can skip the backups).
If you are returning your phone for warranty, run Triangle Away app before unrooting, that will erases any traces of root. (Also installing a stock firmware DOES NOT increase binary count.)
This method is using ODIN and Windows computer. If you have Linux or Mac computer, you can also use Mobile ODIN PRO (on Play Store) to do the same thing.
So, let’s unroot/unbrick your Galaxy Note 2.
