And if you still do not succeed ica (though the instructions are now very straightforward) I am sure there are some people here who would help you with the device directly.

Maybe you are willing to pay for shipment to and from someone who can deal with your device. Maybe somebody even lives close enough you can just visit him. It will certainly be cheaper and more successful than a visit to an repair store.

I would offer myself to unlock your device and even to put files onto an USB key if you send one with it. I am based in Germany near Munich.
