I have a new MK5 and this is exactly the steps I have taken only to be blocked by the "SecurityNotice" webpage that leads to nowhere. Correct me if I am wrong, but as I understood it the dip switches are for boot mode only, so if the page is requesting you to change your dip settings in order to proceed how are the dip changes even being effective. (Unless the intention is for you to power down switch them then power up again.) which I did with no luck!!!
I have tried everything that "cvnistc ", has done right after a flash update was interupted. Any help on this matter would be greatly appreciated!!
