Okay, to my big shock, my phone suddenly seized to work... It was charged a few hours ago and I just had it laying, nothing special. It's a flat-stock N-9005. I wanted to check it and it did not respond to the Home Key. I tried powering it on, nothing. I took the battery out and hooked a multimeter on it and it read 4.02 Volts so plenty of power left so it wasn't drained either. Also tried putting it in Recovery and Download mode but the thing seems dead. Any idea what else I could try?
