jag apears to be dead after firmware update

[Alex Chambers]

one of our black jaguars died when we were using it to firmware update a grey jag to v.101 using a db9 cable into a black jag with a connection into the grey jag with terminator at the end. has any one experienced a similar issue and if so how can we save our jag from being bricked from the failed attempt to update one of our grey jags? Ever since we tried this bdc com cant seem to connect to the jag, or at least it no longer can use firmware update which is usually how our team quickly identifies that bdc com has communication.

p.s in the past we have done this using the same cable we put together a year ago and nothing went wrong.
