I can confirm that kwboot works with the Iomega IX4-200d which has BootRom v1.11 The trick is to flip the switch and start kwboot after approx 1 second. Quite reliable though. My command is kwboot -b uboot.2016.05-tld-1.sheevaplug.mtd0.kwb -B 115200 -t -p /dev/... I'm not sure whether this uboot image came from this thread, but it's certainly here on the forum.by pareidolia - uBoot
