In any case, the VuJ chip will work on these motherboard, I have the same board tested with it.
Further to determine if you have a security chip issue, or a bricked nand flash chip can be seen when you connect the box to the serial port, and using a terminal program as Putty, or Hyperterminal.
The output from it should give the answer.

When you get no output, then you should use the jtag method to see if you can bring back the nand flash chip back to life.

If your solo2 has no issues, then it has no sense to modify it to the VuJ chip.
