Hi.. not heard of that before i must admit.. but as a first instinct did you leave the battery disconnected for long enough..? i think most people go for ten minutes, others 30 munutes just for certainty.. the other thought, do you have the correct rating battery in the first place..?
Hopefully there weren't any sparks flying anywhere when you were handling the jump leads, i guess i'm hoping your ecu hasn't been damaged somehow.
Let us know if you have any progress,
