Yeah I read your article very carefully and no I'm not trying to switch between regions. I'm trying to upgrade from 8.1J to 9.2J. My guess is that the 3DS is requesting the ticket for the browser since this unit does not have one. Would you mind to provide a ticket response for it?
I would really appreciate your help sir.
Thanks for your time sharing your knowledge!
Can you post your SOAP request with the identifying information stripped out?
