Martin knows best.....
but you could also try reading/writing nand with progskeet(This isnt an Team-Xecuter product, i know, but it might help), also Team Cygnos put out a device similar to the demon that is just a nand reader/writer, or Demon(I would suggest this if it isnt a BB jasper). these both bypass the southbridge for nand read/write. if the system boots after this, then use that to write your glitch image, and you can skip the SPI programming.
