While flashing back to stock using Odin, something happened after the install and my phone ended up rebooting, and I have not been able to turn it on since. -When attempting to power on normally, phone shows white AT&T screen and hangs there -When attaching USB, phone shows battery screen but battery is all grey and rotating progress icon is frozen. Does not appear to be charging. -Computer does not recognize phone in any state. Latest USB drivers are installed and I have had no issues connecting via USB previously. -Cannot get into download or recovery mode using any volume/power button combination or through adb. Also tried attaching USB with ODIN running while attempting button combinations, inserting/removing battery etc, still nothing. - I have tried removing battery, plugging in usb, hold down up/down/power, plug battery in, let go of power, and it still goes into a stuck grey battery charging screen. Has anyone else experienced this? Anything else I should try?
