blimey, seems bit drastic to just disconnect cluster and then 'loosing' it completely - there must have been more to this than only disconnect 'issue' (not saying of your doing) 😐
your best option is to get SDD software and let someone program it remotely - this way you won't need anyone to fly over 😉 if you are on facebook, join jaguar forums, there's programming magician Sul Jay, i'm sure he will help.
let us know how you get on.
