Hey Ponyma2015, Could you run us through what behavior the switch is currently exhibiting, what led up to this situation, and what recovery procedures you have attempted so far?
oddhome, if you have gone through the recovery steps outlines in previous posts, and are still getting the uboot prompt. It would be best to call into your local support group and get a case open.
I have the same issue. Switch does not get to boot menu. tftpboot does not work. Does anyone have instructions for reloading from u-boot.
