I'm still a little confused since you said you mounted the boot_flash directory. The actual boot flash is a hardware device (typically sde on a 4-drive unit, but likely something else if you are doing this without 4 drives installed) and is not automatically mounted. So did you mount the sde1 partition (or other device if it's different) to boot_flash?
Are you booting with drives installed? The OS has to install on at least one drive before the GUI works properly.
If RAIDar is properly showing the model name and serial number, then you do have an intact vpd file. I'm not sure how far OS4.2.31 gets in booting without a vpd file, so if RAIDar isn't showing that info, then the vpd may be the issue.
