Re: Weird boot failure

There are two possibilities that come to my mind: 1. The main bootloader is corrupt, and when you're depressing the reset button for a certain length of time, you are triggering the backup bootloader. 2. You managed to set the default boot mode to something like Netboot instead of Internal Flash / N...
