Ok I really need someone's help here. I have a Galaxy note 2 with ATT stuck in boot loop. I traded my iphone 5 for it about a month ago. I didn't know the phone was rooted and tried to factory reset on it. Soon I learned that it was a huge mistake because it went in to boot loop. I downloaded odin 3.09 but im afraid to try anything to permanently hard brick the device. Before everything happened it was running android 4.3 and I would like to get it back to stock rom. I need some help, badly.
