For the 3rd time....as far as I know, if your current redboot is in rom 
mode, you will need to boot linux (or some other os) and overwrite it 
from there.  Make sure linux is configured to have redboot partition 
support on.

#
# Memory Technology Devices (MTD)

CONFIG_MTD=y
# CONFIG_MTD_DEBUG is not set
CONFIG_MTD_CONCAT=y
CONFIG_MTD_PARTITIONS=y
CONFIG_MTD_REDBOOT_PARTS=y
CONFIG_MTD_REDBOOT_DIRECTORY_BLOCK=-1
CONFIG_MTD_REDBOOT_PARTS_UNALLOCATED=y
# CONFIG_MTD_REDBOOT_PARTS_READONLY is not set
# CONFIG_MTD_CMDLINE_PARTS is not set
# CONFIG_MTD_AFS_PARTS is not set

Then use a tool like flashcp.  See mtd utils .

bash-3.1# flash_unlock /dev/mtd0
bash-3.1# flashcp -v redboot.bin /dev/mtd0
bash-3.1# reboot

Good luck!
