So, yeah, my phone's been a douche lately and has developed a new symptom making me unable to start it at all.
That's pretty much it, it's frozen on this screen whenever I attempt to charge it and the power button does nothing except turning the screen off. It's been charging all night.
try to reflash the firmware with odin, or go to stock firmware with kies using this guide (you can find s/n of your phone by pulling out the battery)
report if it worked for you
