Even more sorry for a longer delay :)
So I'm using the Chrome App. I'm happy to report that I have updated to v1.07.
I honestly have no idea what finally fixed it, i've reinstalled the Chrome IDE many times, I've switched COM ports because sometimes it sees a port then when in bootloader mode that port now disappears.
Then all of a sudden COM port 5 appears in bootloader mode and boom I get to update the firmware.
So relieved it's finally worked but sorry can't explain what the cause was.
