I have an ASR920 that does not boot because the bootflash seems to be broken. I tried to boot from USB but since the bootflash seems to be checked during the boot sequence I cannot boot nor do I see a possibility to format the bootflash. Does anybody see a trick to at least being able to boot the router to see if the bootflash can be reformatted?
Any hint is appreciated.
