Which version of the bootrom does the phone have?
I have been told that once you upgrade to version 3.x,
you cannot go back (to say, version 2.6.1).
Some of the newer phones are being shipped with 3.x.

If your bootrom.ld file on your ftp boot server is version 2.x,
and your phone already has a 3.x image, then you will see the 0x4020
error.  It cannot replace the image, and the only thing it can do is
reboot.
