So first off, let me fully admit that I screwed up here! I was flashing the CIMC firmware on a new C220 M4 I picked up, without any UPS connected, and the power went out for 2 seconds, killing the server right in the middle of the firmware flash. Cisco seems to think that flashing a single firmware should take upwards of 2 hours, so that greatly increases your chances of encountering an issue - don't take chances and use a UPS!!
Since the power blip, I've been trying to flash the CIMC firmware (3.0.3f to 4.1.2k), but I continue to receive errors.
Flashing from the firmware ISO it takes FOREVER, but eventually gets to about 80% of the progress bar and fails with a 1902 error. Flashing within CIMC is much faster, only about 5 minutes, but it also gives an error that the flash failed. I've tried power cycling the server, holding power button for 30 seconds, and even tried flashing the 3.0.3f version again - all with no luck.
Reading online it sounds like there's some way that Cisco can correct this, likely with a NAND format, but I cannot find any mention of how to do this myself other than that it involves TFTP or something similar.
Anyone had any luck with fixing a firmware flash issue on these servers, or have some idea how to format the NAND?
