I was about to use Odin to flash the ATI1 firmware on my N20U (US unlocked), but I ran into a problem. When I reboot to the bootloader, instead of connecting to Odin and showing the familiar download screen, the phone shows a bootloader screen that lets me cycle through several options including Start, Restart Bootloader, Recovery, and Power Off, plus a few others. However, no matter which option I’ve cycled to, when I press the power button to select the option, nothing happens. The only way I can get out of the bootloader at all is to hold the Power and Volume Down buttons simultaneously for several seconds, forcing the phone to reboot again.
Any idea what the problem is and how to fix it?
