I really need some help. So I tried to root my device to have android N on it. I used odin and applied the Kernel for the at&t version and it said it succeeded. I unplugged the phone from my computer and it started to reboot. But it stuck in the reboot screen which i heard was normal. It didnt reboot again and again instead it just stayed on the "Galaxy S6 edge: powered by android" screen forever, i was able to get into recovery mode by holding the home button, volume down, and power, and when it went black for a second, taking my fingers off the keys and then holding the home, volume UP, and power button. I tried wiping the cache, doing a factory reset, i went through basically everything but whether clicking on reboot or shutting it down and starting it up again the "Samsung Galasy s6 edge: powered by android" screen stayed on. So i left it on and the phone died, now when i plug it in for the first 10 or 15 minutes the grey oultine of a battery with a lightning bolt comes up, but after a bit it starts turning off and then on showing the device isnt getting enough juice. I saw that being stuck in a reboot was normal but im not sure why this happens. I have a backup phone (S3) that i can use to call people but i would really like to get this fixed. The phone itself is in good condition its JUST the software.
