I suggest that you use this software card on other unit. This could be sure whether the unit or card is having problem.
Is this the Aisys FMI Kit Number is 2077667-001 (QTY: 1pcs..
Next if problem still persists, the Compact Flash Card, formatted (item 26 – see picture below), p/n M1055008 on the HPDU CPU board could be damaged.
This is not included when you order a new CPU board and it needs to be transferred to the replacement board.
I would first ask if you have replaced the CPU board, did you transfer the CFC?
If you did and still are unable to load SW, you should replace the CFC.
You should also confirm only one board replaced at a time, and downloaded SW each time - reference TRM Section 9.1.
