Taken from another forum:
I've been in touch with one of the manufactures of the OpenBox, and apparently this can be caused by installing the Firmware, Dump or Misc files incorrectly, if for example you install new firmware or files without first removing the old one, it can on occasions, depending upon the size and file being installed become to large for the allocated space assigned for software updates, and as parts of the previous file was not removed, it will take up a portion of the allotted space required by the new update, as certain elements or parts of the installation can then end up overwriting, and damaging the bootloader, which will then give the Clone error message, as the software has corrupted the bootloader by overflow.
Try contacting your supplier, and see if he can send you a loader and the required bootloader software [most companys have a loader for re-installing the bootloader software, but they prefer not to make them public downloads] and you should be able to fix the problem yourself, that is if it is a bootloader problem.
