Those following this thread may be interested to read the advice I finally received from Hornby UK.Notice he suggests waiting 30 seconds! not 15 for each step.Then he suggests of that doesn;t work to attempt to update without waiting at all during each step.About to try it now and see what happens. Dear Sir, Thank you for your email, Please try the following steps yourself - 1) Hold down STOP button.2) Plug power cable in.3) Keep STOP button held for 30 seconds.4) Release STOP button. Wait 30 seconds.5) Plug in USB cable.6) Launch Elite update, and try to update. IF this does not work, or an Error message comes up: 1) Pull both cables from Elite.2) Straight away, hold STOP button down, and plug power cable in.3) Do NOT wait 30 seconds, release STOP button once power cable is in.4) Do NOT wait 30 seconds, plug USB cable in straight away.5) Re-try update. This should cure your problem. If you have any issues with this, please come back to us. Kind Regards, Matt Jordan Customer Care Advisor
