Do it carefully.... Just try not to touch the butterfly... there is a guide on youtube I think, (did you do the TB reset too?)...
You may want to get it too Abbey so they can hook it up and do a reading, And whilst they are there get them to Revup it!!
I may well take it down to abbey and get her done but i was thinking... if abbey - mark or whoever just said they are working on it then the problem isnt resolved yet, so no point me going there yet?
On top of this i dont want the re-map to invalidate my warranty
