Nandroid restore always fail at the boot.img

[DreamcastDC]

Can anyone help me, I'm trying to do a Nandroid restore, and it keep failing to restore when I try to flash the boot.img.

Here is what I did:
fastboot flash system system.img - Flash OK
fastboot flash userdata data.img -Flash OK
fastboot flash boot boot.img - Flash failed and I get this msg: Writing 'boot' ... FAILED (remote: image update error)

Can anyone tell me what is wrong?

Thanks

Nandroid back up again. Just flash the new boot.img and see if that works, if you alreayd tried that then try a new SPL, if that doesn't work... oh well...

i get the same problem mate have you by any chance sent the phone back to HTC for any reason? I have tried and tried and tried to get this to work with many different spl's and no luck.Also posted a thread on xda forums.
H E R E please let me know if you have any success i think we may need to somehow get permission of the /dev/mtd/mtd2 sector (boot) but i dunno how!
