There is a problem with the flash ram. it may be the expansion ram on the main board. Open up the XD9 and look for the large board in the middle, hopefully you will see a ram expansion port with some ram in there. You could try removing the ram, cleaning the connections and re-inserting - ot try running the tests without the ram.

If the test still shows an error without the ram installed then you either need to replace the CPU board or have the built in flash memory replaced (special tools required)
