Thank you for your reply, I tried the oldest version of the HD500x edit software from the downloads section v2.22 and still got the same error, it shows that it starts to transfer the patches but stalls out at 2% and then shows this error
I also followed the guide you kindly pasted above and got the same issue:
After this dialog displays the POD shows Updating Flash on the screen and stays like that until power cycled.
I've tried different USB ports and different cables and proved cables and ports all functioning ok.
My last ditch attempt will be to install windows 7 on my laptop, really don't want to have to do this but running out of options.
