I tried to do clean install of 643 and it failed.  Actually, it worked
for the first time.  Then, I realized that I forgot to put Q2D05
firmware on my USB memory.  So I put the .rom file and tried the clean
installation again.  Then during the boot process I got:

tar: Short read

In the future, if you're only updating the ofw, you should just get to the ok prompt and type:  ok flash path_to_file

Also, after the firmware is upgraded, it reboots the machine, which would then lead the machine into trying to do an upgrade instead of a clean install if you don't hold the square key. That is probably why it created a backup and tried to restore from it. This means there may be some issues with the auto-reinstallation process, which should be looked into.
