I tried the above and it worked, if you have the time, try it to and let me know how it goes! :)

Well, perhaps you can backup your uboot, but it seems that you can't write it back this way:

# mtd write u-boot.bin mtd0 Could not open mtd device: mtd0 Can't open device for writing!

[edit]
You can, but it's not as trivial, so it requires some hoop jumping to get it done.

# mtd write u-boot-env.bin u-boot-env Unlocking u-boot-env ... Writing from u-boot-env.bin to u-boot-env ... # mtd write u-boot.bin u-boot Unlocking u-boot ... Writing from u-boot.bin to u-boot ...

I found that reproducable when i got error message for not enough disk space left. ... afterwards i saw such errors...start from zero. Restore factory default and do sysbackup with nee binary... Pain in the a... but thats the only way that worked for me..

Just want to chime and point everyone to our documentation on the topics discussed above:
