I know that there is the Recovery Menu, that can be used to reflash firmware in case of firmware failure. This is entered using the Reset Button.
But is the recovery menu 'always' there, in all cases of firmware failure?, I ask as I have seen traces of it in firmware images, so it might be a part of the update firmware file, so will not be available in all cases of firmware flash failure.
Is there some way apart from the recovery menu, to flash firmware, no matter how bad the firmware flash failure was, e.g. flashing an completely empty file (assuming it happened). What are the alternative re-flash method choices in this situation?
I have seen a USB method, with software on PC to do the flashing. But what minimum condition does this reply the device to be in ?
